Safety Advisement and PrecautionsModern photo processing equipment is simple and safe to operate. Thefollowing precautions should be taken in the operation of all machinery:

Mechanical:• Processors should not be left to operate unattended.When no one is on the lab premises, the power andwater supplies to the processor should be turnedoff.

• Be careful not to let loose clothing or jewelry becometangled in operating parts of processing equipment.

• Whenever possible, turn equipment off before attemptingto service it.

Electrical:• Disconnect power at wall outlet before attempting to

service electrical components.

• Remove loose jewelry before working on electrical equip-ment, to prevent it from coming in contact with power.

• All equipment installations must be thoroughly grounded.

• Any water and chemistry spilled in the base section of theprocessor must be wiped up immediately, to prevent pos-sible short circuiting of electric components.

Chemical:• Follow all the safety precautions listed by photographic

chemical manufacturer.

• Use eye and hand protection when mixing chemicals or per-forming routine maintenance on the chemical racks or

tanks.

• Ensure proper ventilation in chemical mixing area.

• Wipe up spilled chemicals promptly. Avoid spills and con-tamination by using the optional rack carrier tray, avail-able as an accessory. The carrier tray should be rinsedclean after each use.

Keypad Functions

The keypad is used to view current controlreadings and settings, and to change settings.Functions controlled by the keypad include:

– Process Temperature– Temperature Deadband– Dryer Temperature– Wash Timing– Process Time– Feed Delay Time– Dryer Delay Time– Replenishment Rates– Infra-red Scanner Pulse Count

Programming the microprocessor control withthe keypad is almost as easy as setting a digital

clock:

Use the Left and Right Arrow Keys to change the functionthat you are viewing, As you press the keys, you will note thatthe indicator light moves to a different function for each keypress. In this mode, the display will show the actual readingfor the indicated function. For example, when "Dev. 1" isindicated, the actual tank temperature for Dev. 1 is dis-played.

Use the asterisk key to display the Setpoint for the indicaterdfunction. This is the programmed value that you wish theprocessor to maintain.

DATA SELECT

Normally, the microprocessor control panel isdelivered fully programmed. Should any changes

be required, they can be easily made.

1. The control panel normally displays the actual (first)developer tank temperature. To see the temperature con-troller setting, press the asterisk (*) key once. When thetemperature controller setpoint is displayed, the up anddown arrows are illuminated. This indicates that it is possibleto raise or lower the setpoint by simply pressing the properarrow key. Holding the key in will cause the setpoint tochange at a faster rate.

2. When the setpoint has been programmed, the deadbandsettings may be checked by pressing the asterisk key asecond time. The deadband is the temperature tolerancefor turning heaters on. The recommended deadband set-ting is 0.2 °C., which is equal to ±0.1 °C. Although it ispossible to change the deadband setting, such changesare not recommended. Too tight a deadband setting willcause more excessive wear on heating and cooling compo-nents with no actual gain in performance.

NOTE: The last three process settings aredisabled on the Colette Pro processors for RA-4

and Black & White materials.

Programming TechniqueWhen the developer tank is heating, its indicator light willflash slowly.When the developer tank is cooling the indicator light willflash rapidly.When the tank is at the set temperature, the light will glowsteadily.

Dryer Temperature

Temperature Indication

3. To view the dryer temperature, press the left arrow untilthe dryer indicator is illuminated. The current dryer tempera-ture will be displayed.

To view the dryer temperature setpoint, press the asteriskkey. The dryer power percentage set point will be displayed,followed by the letter 'P' to indicate percentage and the upand down arrows will be illuminated, to indicate that thedryer setpoint may be changed, if so desired.

The setting for dryer temperature is expressed inpercentage of total dryer power. The relationshipbetween dryer power percentage and dryertemperature output is affected by several variablefactors, such as room temperature, room humidityand workload. As a general rule, use the lowestpossible percentage (of total temperature output)to achieve drying. The higher the percentagesetting the hotter the dryer will get.

*To achieve optimum performance, the optional Infra-red heating elements takeslightly longer than resistive heaters. Therefore, we recommend at least 3 minutes beprovided for warm-up.

NOTE:The operating temperature may need to be raised for long rolls. CAUTION: Itis recommended that the dryer be set to the minimum operating temperature to avoidexcessive curling of cut-sheet materials in the dryer section.

5. Process time is displayed when its indicator is illuminated.This is the time for which the machine will run after the lastsheet of paper has been fed into it. The control panel countsdown after paper has been fed, so the time displayed is thenumber of minutes remaining before the processor will shutitself off. (Minutes are expressed as decimals by the control, so "6.5" means six minutes, 30 seconds). To change theprocess time, press the asterisk key and use the up or downkey.

6. Feed delay time is displayed when its indicator is illumi-nated. This is the time for which the panel waits after the lastpiece of paper has cleared the sensor bar before soundingthe paper feed tone. This delay may be set by pressing theasterisk key and using the up and down arrows: 15 sec.paper & 30 sec. display.

7. Dryer delay time is displayed when its indicator is illumi-nated and the asterisk key is depressed. This is the numberof minutes for which the processor delays turning the dryeron after a print has been fed into the processor. The dryerdelay must be at least *2 minutes shorter than the processtime, this allows the heating elements to reach maximumoperating efficiency. The display counts down the timeremaining before the dryer will come on. To change thesetting, use the asterisk key and up and down arrows. Themaximum dryer delay time setting is always two minutesshorter than the current dry to dry time.

8. Replenisher time is the number of seconds the replenish-ment pump will run once the infrared area sensing systemhas triggered it. The display counts down the remainingseconds when the pump is running. Use the asterisk and upand down arrow keys to change this setting.

9. The last function displayed is the replenishment pulsecount, which is displayed when none of the indicator lightsis on. Pulse count is the number of replenishment pulsesneeded to trigger the replenishment pump. This is a factorysetting, and changes are not recommended. However, thepulse count display is a useful tool for troubleshooting re-plenishment problems.

Control Switches

Whenever the processor is switched on, the control systemautomatically starts the tempering system and recirculationpumps The transport motor will briefly operate at regularintervals to ensure uniformity.

When paper is fed the processor automatically turns thedrive motor on, and opens the water solenoid. The dryerturns on after a preset time has passed (dryer delay). Theprocessor then shuts down automatically after the last printhas emerged from the dryer. The infrared replenishmentsystem operates to ensure precise replenishment for theamount of paper fed.

The manual mode allows manual operation of the drivemotor, and dryer. This mode is not intended for general use.It is used for systems diagnostics and as a backup shouldthere be a problem with the automatic electronics.

The replenishment pushbutton enables the operator to re-plenish the chemistry manually. The switch should not beoperated for more than 45 seconds at a time, to avoidoverheating the replenishment pump motors. For anyamount of replenishment larger than a few hundred millili-ters, do not use the pumps, simply replenish by placing therequired amount directly into the processor tank.

"Dura" Speed Capability

PAPER

DISPLAY Duratrans is Kodak's trade name for a display printmaterial coated on a translucent plastic base.Duraclear RA is a similar material with a clear filmbase. These materials may be rear-illuminated foruse as a display transparency. These materialsare processed in standard RA-4 chemistry, but alonger development time than the standard timemust be used, and a higher replenishment ratethan normal must also be used. Therefore, anyprocessor used for Duratrans must be equippedwith a variable speed motor, and a means ofchanging the replenishment. On Colex rollertranspor t processors these functions areaccomplished automatically on the control panelby the DISPLAY switch. This switch willautomatically select the correct motor speed forthe material selected.

When the DISPLAY switch is pressed the following changesare made to the normal process parameters:

• Dryer and drive motor are automatically switched tomanual. Both dryer and drive motor will operate continu-ously until the DISPLAY key is deactivated at the end ofthe process run.

• Motor speed is slowed to provide the correct processingtimes for display materials.

• Replenishment is automatic.

"Display" materials require approximately 2.5 times the nor-mal replenishment rate used for ordinary color paper. Sincethe processor transport speed is slowed down from 45 sec-onds development to 110 seconds, no replenishment changeshould be required.

NOTE: Always return the processor to normalAutomatic operation after the end of the DisplayMaterial run.

The Chemical Replenishment SystemWhenever photographic material is processed, chemicalconstituents of the developer are used up and by-productsare left behind in the processing solution. Replenisher solu-tions are formulated to restore the chemical to its originalactivity and to dilute the by-products to the proper level. Itis therefore necessary to add the proper amount ofreplenisher for the amount of paper that has been pro-cessed.

This task is performed automatically on the processor by theInfra-Red sensor pairs located on the scanner bar. (#1)These sensors emit pulses of infra-red light which have noeffect on photographic emulsions. When paper is beneaththe scanner bar, the pulses are reflected and are sensed bythe sensor.

The pulses are then transmitted to the control panel (#2),where they are counted by the microprocessor. When thenumber of pulses reaches the amount that has been pro-grammed on the microprocessor, the replenishment timerfunction is started .

The replenishment timer runs the replenishment pump(s) (#3) for the number of seconds that have been preset on themicroprocessor (#2). Any number from 5 to 39 seconds maybe set on the computer. When the replenishment pumpsare activated, the replenisher solutions are drawn throughfootvalves located at the bottom of the replenisher tanks(#4 & 5) to the processor tanks (#6 &7). The footvalves (#8)contain a filter and a checkvalve which prevents chemistryfrom flowing back into the replenisher tank.

The calculations illustrated above translate intothe following formula:

Max. Width x Speedx Repl. Rate (ml/ft 2)

144 (ft 2)

It should be remembered that all replenishment rates givenby chemical manufacturers are merely suggestions, andshould be verified by careful observation of quality controlplots. If the plots trend upwards, the chemistry is overactive,and you may need to lower replenishment rates. If theytrend downward, the chemistry is underactive, and replen-ishment rates need to be raised. Once the equipment isinstalled, replenishment rates may be modified by changingthe replenishment timer setting on the front control panel,and adjusting the pump output volume if necessary.

CalibrationThe pulse count and scan rate of the replenishment systemhave been preset at the factory to cause the replenishmentpumps to start every minute if all the sensors in the scannerbar are activated. Therefore, the replenishment systemmust be calibrated to provide replenishment for an area ofpaper equal to the width of the processor in inches multi-plied by the speed in inches per minute.

The Chemical Replenishment Rates

Please note: The figures listed are suggestions only. They represent mL/cycle and are based on a replenishment rate prescribed as a suggestedstarting point. Actual replenishment rates will vary with operating conditions.

Refer to Kodak RA-4 process manual for information regarding processmonitoring and the calculation of utilization percentage as it affects thereplenishment rates. Utilization percentage can significantly affect thequality of the processed materials and therefore must be taken into accountwhen determining operable replenishment rates.

For B&W, use the recommended replenishment rates listed by the chemicalmanufacturer. The rates given may be used in the formula on the previouspage to determine your initial replenishment rate. Further testing mayreveal slight deviations from the manufacturers recommendations.

Checking the Replenishment RatesTo check the actual replenisher volume delivered by thereplenishment system, use a 500 ml graduated cylinder.Remove the replenishment tube from the processor tankthat you are testing and insert it into the graduated cylinder,being careful not to allow any chemical to overflow thegraduate.

Insert sufficient paper under the scanner bar to fill the entirewidth of the scanner area. This will activate the replenish-ment pumping cycle. Insert the paper far enough that thesensors are activated, but not so far that it actually feedsinto the processor. A piece of writing paper may be used ifyou don't have any photo paper. Be sure not to let it go intothe chemistry.

When the replenisher pumps stop, turn the main powerswitch off. Remove the replenishment tube from the gradu-ated cylinder. Read the volume of chemistry in the cylinderto determine the amount pumped during the replenishmentcycle. Compare this amount with the amount which youhave calculated for your processor's width and speed. If thevalues are within 5% of each other, leave the replenishmenttime at its programmed value. If the values differ by morethan 5%, divide the amount pumped by the programmedtime to determine the amount pumped per second. Dividethe number from the table by this value to determine thenumber of seconds to program on the replenishment timer.

If a number other than the programmed value needs to beset to obtain the correct replenishment, repeat these stepsusing the newly programmed replenishment time to con-firm your calculations.

Replace the replenishment tubes in their respective tanksand remove paper from below the scanner bar beforeturning the main power switch on.

The Replenishment PumpGorman Rupp • Replenish-ment Pump

Both the Single and Double Metering Pumps are cam oper-ated bellows pumps. The pump head is mounted on a singlepump motor. An eccentric cam activates the cam of eachpump head as it rotates. The amount of chemistry pumpedmay be adjusted by means of the adjustment screw locatedon each cam. This adjustment changes the length of thepump stroke and therefore the amount of chemistry pumpedper stroke. The stroke adjustment pointer is numbered inpercent for ease of setting, and is directly proportional tothe amount of chemistry pumped by the stroke.

Adjusting Cam & lockingSet Screws

The adjustment screw may be turned to the percentage ofthe rated output using a standard screwdriver. Exact ratesdepend upon particular application which is best deter-mined with an on-site testing and calibration procedure.Reproducible results cannot be obtained below 10% ofmaximum stroke length.

Do not restrict flow with control valves, unless authorized andmodified by a factory representative.

Cleaning The Poppet ValveThe poppet valves are designed in such a way that chem-istry can only flow in one direction through them, withoutflowing backwards. However, if dirt or chemical crystalsbecome trapped between the check-valve and check-valve stem, backflow is possible, and an erratic replenish-ment rate can result. Replenishment rates should be checkedevery month or so to be sure that they are correct. Shouldthey be erratic, a simple cleaning will often solve the prob-lem. Clamp off the replenishment hoses on both sides,unscrew the hose fittings, and remove the poppet valvesand springs, then rinse them with water. Examine the areabetween the valve stems and poppet valves for any foreignmatter, and also clean the inside of the hose fitting.

Check-valve Cleaning

Once the poppet valves have been cleaned, proceed tore-assemble the pump. Be careful to replace the poppetvalves back the same way you found them, since they mustface in the correct direction if they are to work properly. Thenarrow end of the checkvalve should point away from thedirection of chemical flow arrow engraved on the top of thepump.

The Tempering SystemWhen the Developer or Bleach drops below the correctprocessing temperature, the thermostat probe (#1) sensesthe temperature change and activates the temperaturecontroller in the Control Panel.

The Control Panel in turn activates the Circulation Motor (#2)and the Heater (#3). The Circulation Motor pumps the tem-pered water through the Heat Transfer Coil (#4). The recircu-lation system is also activated to ensure even temperingthroughout the entire tank. In standby mode, the systembriefly engages the transport motor at regular intervals, toprevent the possible buildup of chemical by-products in thetank during periods of low usage. The system also includesan air purging "T" vent (#5) and a tempering system fillersolenoid (#6 shown in the off position - with the magnetdisengaged) which should be left in the off position duringnormal operation.

The Wash Water System Water Control Panel

All water going into the processor originates at the watercontrol panel. The water panel should be set about 5°Celsius below the actual process temperature, or at 92° F.for Kodak RA-4.

The water solenoid is located on the processor base section,under the tank section. The hose from the solenoid is con-nected to the Developer/Bleach Crossover Wash ControlValve and the Wash System Supply Valve. The Developer/Bleach Crossover Wash Control Valve is used to regulate theflow rate in the chemical crossover troughs. The WaterSystem Supply Valve is used to control the amount of waterpassing through the wash tanks.

IMPORTANT: Proper adjustment of crossoverwash flow is critical. Too low a flow rate will not wetthe rollers. Too much flow will result in wateroverflowing the trough and diluting the developerand bleach tanks. The crossover wash flow shouldbe checked periodically before starting theprocessor. Please refer to the procedure on thefollowing page for instruction on crossover flowadjustment.

Filter and Overflow StandpipesFiltration and overflow are achieved by means of standpipesscrewed into the bottom of the tank, on the side away fromthe drive chain. The filter is covered by a tubular nylon meshfilter material and held in place using nylon tie wraps. Thefilter is screwed into the return line from the recirculationpump, and is located toward the rear (dryer side) of thetank. The filter should be removed and cleaned bybackflushing with running water at least once a month.The overflow standpipe is screwed into the tank drain. Todrain the tank, simply unscrew the standpipe. Remove thestandpipe slowly to prevent any splashing of the chemistryas it surges down the drain. A hexagon shaped key is pro-vided for this purpose.

Unique Rack Design

Reinforced CrossoverSection

The Standard Colex fea-tures not found in othercompetitive systems are:self cleaning crossovers,submerged racks, stag-gered rol lers and thesealed tank concept.

The self Cleaning Cross-overs rinse and squeegeethe material as it is passedfrom one solution to an-other, thereby removingexcessive carryover andreducing contamination.

The Submerged Racks re-duce oxidation and crys-tallization of chemistry,eliminating the scratchesor abrasions from hard-ened solids in suspension.

The Staggered Rollers per-mit the material to trans-port through the systemwithout emulsion pressure,further reducing the possi-bil ity of scratches andmarks.

Processor Rack Removal & Replacement

Rack Removal

The procedure for removing and installing the rack is asimple operation. Normally two persons can easily accom-plish the task of rack removal and replacement.

Carefully remove the rack, so as not to cause any splash-ing. Remove the rack sections with the transport hooksprovided with the processor. Removing the rack will beeasier if you lift both sides at the same rate, this will keep therack from binding inside the tank . Always take notice ofrack orientation when removing and replacing the racks.All chemistry racks should be kept well away from the otherchemistry racks. The Developer Rack can be easily con-taminated by very small amounts of bleach!

Take extra care when replacing the rack sections and lowerthe racks slowly, this is especially important when the tanksare empty. Be sure that the drive sprocket is correctly seatedon the chain.

Rack Replacement( Not recommended

when the tanks areempty!)

Sheet Paper FeedingSheet paper should be fed into the processoremulsion (light-sensitive) side down. It is betterto feed prints into the processor with the long sideas the length, and the shorter side as the width, asillustrated below. Simply push the paper forwardinto the feed opening until the paper catches thefeed rollers and the rollers start to pull it into theprocessor. Be sure that your hands are clean anddry before touching photo paper.

Do Not attempt to feed prints smaller than 4 x 5inch test strips, as they may not travel through theracks properly.

Prints may be fed into the processor side by side.It is best to let one print "lead" the other by an inchor two, as shown above. This helps both prints totravel through the processor without any side toside motion.

D 6.36

Roll Paper FeedingIf roll paper is to be processed, an optional Roll Feed/Takeup system should be used. Thisconsists of a cradle which holds the roll paper straight so that it feeds into the processorevenly, and a motorized take-up that winds the processed paper onto a roll as it comesout of the dryer. It is recommended that the flanges always be used on the paper corewhenever roll paper is processed, to ensure even feeding. The Feed Cover allows thedarkroom lights to be turned on while roll paper is being processed

Failure to properly employ a Roll Feed/Takeup for long roll processing maydamage the paper, in severe cases damage to the processor may result.Feed Roll Paper emulsion down, threaded between feed rollers.

The locking collars should be used to retain the flangeguides, when long rolls are to be fed into the processor. It isnecessary to retain the guides at only one side of the flange.

Paper Sensor & Scanner BarThe unit has internal (#1) Scanner Bar equipped with a row ofInfrared sensors (#2). These sensors continually read from leftto right, searching for any indication of material being in-serted into the machine. As material passes beneath thesensors the width and length of the material is calculated bythe electronic feedback (pulses) from the sensors. After apredetermined amount of pulses the replenishment systemwill pump one cycle of replenishment into the chemistrytanks.

Daily Maintenance ScheduleStart-up

Before Start-up: Turn water supply on at the water controlpanel.

Start Machine.

Before Production: Check tempered water supply tempera-ture at the water control panel and adjust if needed.

Before Production: Check water flow rate (GPM) at thewater control panel and adjust if needed.

Before Production: Fill a spray bottle similar to those used forwindow cleaner with warm water and lightly spray thecrossover roller and drive gear sections of each rack toremove any chemical deposits. DO NOT SPRAY ENTRY ROLL-ERS!

Before Production: Check chemistry solution levels and topoff with water if needed.

Before Production: Check crossover flow (manual mode)and adjust if needed.

Before Production: Check replenishment supply and mixchemistry if needed.

Before Production: Confirm that process temperature hasbeen achieved at display, and check that transport systemis running smoothly.

Before Production: Confirm scanner bar and replenishmentpump operation by running a few (1-2 rows across full ma-chine width) clean-up sheets, fogged or old emulsion paper(RA-4 ONLY!) which you have saved.

Before Production: Run a process control strip and takeappropriate action if necessary.

Shut-downBefore Shut-down: Purge the wash tanks. This will help pre-vent the build-up of algae.

Before Shut-down: Turn water supply off at water controlpanel.

Shut machine off at control panel.

Weekly Maintenance ScheduleRemove wash racks and all removable crossover rollers.Clean the rollers with water and a Scotchbrite pad orsimilar product. Do Not use steel wool or highly abrasiveproducts. Inspect and clean if necessary, the crossovertrough & trough drainage hole located at the base ofdrain stem.

One at a time - remove each chemical filter standpipe(not the drain standpipe - page 4.6) from each tank byunscrewing it with the hexagonal wrench. Backflush eachfilter to loosen and remove any debris. Replace eachfilter pipe (do not overtighten!) before proceeding toremove and clean the next filter standpipe.

WARNING!Do not reverse the pipe positions - fluids will expel from theprocessor. All Colette Pro processors have been water testedand are shipped with the pipes in the proper position.

Examine the base of the processor for leaks or chemicalspills. If any are found, confirm that the power to theprocessor is off before cleaning them up. Check hosefittings and tighten or replace the hose & clamps if nec-essary.

Examine the feed tray, remove any paper trimmings anddirt which may have settled on the loading surface. Besure the feed tray surface is dry before loading anymaterials for processing. DO NOT spray cleaning sub-stances directly onto Feed Tray! The Feed Tray should becleaned with a pre-moistened cloth or paper towel.

Clean the outside of the processor with Fantastic orsimilar spray cleaner. DO NOT spray cleaning substancesdirectly onto Control Panel! The Control Panel should becleaned with a pre-moistened cloth or paper towel.

Caution! Chemical solutions may behazardous. Use adequate hand and eyeprotection when handling componentsused in chemical solutions.

Monthly Maintenance ScheduleChange the filter cartridge in the Water Control Panel.

Check all fittings.

Inspect recirculation pumps.

In manual mode test and confirm replenishment pumpoperation, and inspect replenishment lines for kinks whichmay restrict flow and reduce pump life.

Check and confirm proper settings for Developer Tempera-ture, Deadband, Dryer Temperature, Process Run Time, Pa-per Feed Delay, Replenishment Pump Time, and Replenish-ment Pulse Count.

Every three months

Lubricate the processor drive chain with a light machine oil.

Replace chemical filter pipe material.

Remove the replenishment filter foot valves from the replen-ishment tanks and clean the filter screens. Replace themafter cleaning.

The dryer rack may be removed from the processor andcompressed air may be used to blow dust off the foamrubber rollers. The clear plastic covers may be cleaned witha dish detergent. Do not use a glass cleaner, as this canscratch the plastic covers.
