EDITORIAL

B&W is 'Where It's At!'Which is more im-

portant or the printerservice industry, color or

black and white printers?Color certainly has

power. Blue calms and redexcites us, it is said. A lit-tle color on an otherwisemonochrome page seizes our attention. Because it canbe used to manipulate us, color is a persuasive orce.

Most business printing, however, does not need tobe gorgeous, but rather legible and economical. Teseneeds are met perectly by monochrome laser printers.Tey print aster than color laser printers, are more

reliable, last longer, have ewer maintenance parts andhave, best o all, a lower cost-per-page. Tis is why sixout o seven HP users and maintenance kits we sell atLP are or monochrome printers.

Oce printing is integral to society and will remainso or a long time. Whether you need parts or coloror monochrome HP, Lexmark, Oki or Samsung laserprinters, Liberty Parts eam is your wholesale partssource.

PRINTER TECH ARTICLE

Calibrating the ouch ScreenDisplay On HP LaserJets

Te control panels o the larger HP multi-unctionprinters (MFPs) are touch screens: instead o pressingbuttons to navigate printer menus, you touch dier-ent areas on the glass display itsel. Occasionally, thesedisplays become unresponsive and require calibration torestore unctionality. Despite the act that service man-uals routinely overlook this issue, there is a standardprocedure or monochrome and color MFPs released byHP since 2004.

Standard ouch Screen Calibration (or LaserJetM3027, M3035, 4345 MFP, M4345, M5025/5035,9040/50 MFP, M9040/9050, Color LaserJet 4730MFP, 9500 MFP and the 9200C digital sender).

1. Press and hold the number (#) and C keys whilepowering on the printer.

2. Release these keys when a small dot or square ap-pears in the upper let corner* o the display.

3. Precisely touch the small dot or square with apointed, but not sharp, object. Te manuals suggest astylus or a pencil eraser, but a pen cap will do do notuse anything that will scratch or mark the screen.

4. A second small dot or square will appear in the

lower right corner* o the display. ouch this dot in thesame way.

5. Ater a ew seconds, the printer will resume its nor-mal boot sequence. Once it reaches the Ready state, itshould operate normally.

*Te details vary on some models. I both dots appearat once, touch the upper let dot rst, then the lowerright dot. I they appear in dierent corners than de-scribed above, touch the dots in the order that theyappear. I the second dot does not appear, redo the cali-bration procedure.

9000 MFP ouch Screen Calibration

Tis printer has its own procedure. Its successors,the 9040 MFP and 9050 MFP, use the standard one.

1. Hold down 1, 2 and 3 on the keypad while pow-ering on the printer

2. Release the keys when crosses appear in the cor-ners o the display.

3. Gently touch each cross with a thin object.ouching them makes them disappear.

4. Power o the printer once all our crosses are re-moved in this way. Ten power the printer on again.

5. Use the diagnostic menu to access the controlpanel. Select the OUCH SCREEN option.

6. Zigzagging squares appear on the display. Count-ing rom the let, press the second square so that itdarkens. Ten press the seventh and the seventeenth. I

they do not darken when touched, repeat the calibra-tion process.

7. You are nished. Press Start.

I you come across an HP printer with an unrespon-

sive touch screen, and it is not listed above, check themanual or that printer. I the manual does not mentionthis issue, try the standard touch screen calibration, es-pecially i the printer model was released since 2004.

Reverse the above steps to re-assemble the printer.

Important Note: When re-installing the user driveassembly, make sure that the black plastic part o theassembly gets properly coupled to the small white pinin the printer body. Te coupling controls the userentrance fap, which should rotate up when the ront

door is closed. Figure N shows this coupling rom thelet side o the printer; Figure O shows it rom the rearwith the fap up; Figure P shows the rear view withthe fap down. Note that the user is removed in thesephotos. I the black plastic and the white pin are notcoupled properly, this fap will always be down, causingprint quality issues and paper jams.

Replacing the Fuser DriveGear in the P4015 series

Tis series o printers is HPs replacement or theLaserJet 4200/4300 series. It is a similar design, andhas similar problems, including a tendency or the userdrive gear to wear out. In the 4200/4300 printers, youcould oten get away with replacing just one gear (rath-er than the whole swing plate assembly), and there wasa shortcut procedure or doing this. Tis shortcut is notavailable in the P4015 series, but it is still possible toreplace the user drive gear. A step-by-step procedureollows (unless stated otherwise, let-right designationsare as viewed rom the ront o the printer):

1. Remove the toner cartridge and paper cassette.

Ten slightly fex the coverto release the ront edge, rotate the top edge awayrom the printer, and lit up to remove it. Whenre-installing the cover, make sure that the plasticpower switch (on the cover) couples properly to themetal power switch rod (in the printer).

10. Remove the let-side cover. Open the ront cover

and gently fex the retainers to separate them romthe tray 1 arms so that you can open the cover allthe way (this is to provide clearance or the let cov-er). Now release two tabs (one along the top edge othe let cover, and one along the ront edge), rotatethe top o the cover away rom the printer, and litup to remove it.

11. Remove the power supply PCA guide (right sideo printer, toward the back). Remove two screws,release the retaining tab, and slide the guide towardthe rear o the printer to remove it (Fig. B).

12. Remove the power supply. On the right side othe printer, remove our screws and one ground-ing screw (Fig. B). Ten unplug ve cables (Fig. C)rom the DC Controller. Feed these cables throughthe hole in the chassis into the paper tray cavitybelow the power supply. Unhook the power-switchrod rom the chassis, and then pull down to re-move it rom the power supply (note that the rodattaches to the power supply inside the paper traycavity observe this beore removing it so you willknow where to re-attach it later). On the let side o

the printer, remove two screws to remove the an-cover plate (below the an). Tis gives you access tothree cables. Unplug them, and remove our screwswhich correspond to our screws on the other side(Fig.B). Now grasp the power supply rom behind,lit it slightly, and slide it out the back o the printer.NOE: When removing and re-installing the pow-er supply, take care not to dislodge the small rubber

Replacing Rollers inthe CM1312, CM2320,

CP1210/1510 & CP2025With most laser printers, replacing the pickup,

eed, and separation rollers is simple and intuitive, butit is more involved with the printers we will be discuss-ing here: HP LaserJet models CM1312, CM2320,CP1210/1510 series (CP1215, CP1515, andCP1518) and CP2025.

Tese models require you to use the printer menusto rotate the rollers into the correct position or re-placement. Tis article will explain the procedure using

the CM1312 as our primary example. Te other mod-els are similar, and the key dierences are noted at theend o the article.

1: Go into the menu(s) and rotate the roller(s):

NOE: I there is paper in the cassette, the roller rota-tion will pick up one piece o paper, so you may want toempty the cassette beore perorming this step. However,the cassette must be installed or the procedure to work.

a. On the CM1312, start by pressing the Setup but-ton (it has an image o a wrench on it). Tis brings youto a menu listing, but the menu we want (2ndary Ser-

vice) is not among those listed.b. Now press both the let arrow button (on the squaresurrounding OK) and the Cancel button (X) at

the same time, and then release them.Tis brings back the main Ready

screen. Now press Setup again,and we are back to the menu listing,but now our desired menu is listed.

c. Use the arrow buttons to scroll to2ndary Service and press OK to

select it. Now use the arrow buttons toscroll to Pick Roller (Fig. B.) and press OK to selectit.

d. Press OK a second time to rotate the roller.

e. When the roller has nished rotating (you should beable to hear it), turn the power o and then unplug theprinter (disconnect both the power cable and the data/interace cable).

Step 2: Remove/replace the pick roller:

a. Remove the paper cassette, and then careully placethe printer ront-side up (back side resting on the ta-

ble). CAUION: In this orientation, the ADF and scan-ner cover are not captive and can open suddenly. Alwayssupport these pieces beore placing the printer ront-side up.Also note that debris on the work surace can scratch theprinter covers, so beore placing the printer ront-side up,clean the work surace and/or cover it with a clean, drycloth. Te roller should look like Fig. C. (i it looks likeFig. A., it has not been rotated and you may need to re-

peat Step 1 above).b. Release the two white plastic locking tabs (one oneach side o the roller) and remove the roller. I also re-placing the separation roller, it is best to do that beorere-installing the pickup roller.

3. Remove/replace the separation roller.

a. First remove the black plastic roller cover (Fig. D. ) byreleasing the two locking pins (one on each end).

b. Now you should be able to pry the let end o theseparation roller and its holder ree by slightly spread-

ing the surrounding plastic on that side (Fig. E., F.).c. Once the let end is ree, you can lit the entire rollerassembly out. Note that the new roller does not in-clude the plastic holder, so you will have to transer theholder rom the old roller to the new one. Also notethat both the roller and the holder are asymmetrical.Te roller only ts in the holder one way. Te fat spoton the let end o the roller shat (Fig. G.) must ace upso that the retaining clip o the holder ts over it. I itdoesnt seem to t properly, try rotating the holder 180degrees it will t properly in one orientation but notthe other. Te roller/holder assembly also only mounts

into the printer one way with the larger end o theshat to the let. Once the separation roller is mountedin the printer, re-install the roller cover and the pickuproller (this also ts one way only i it doesnt want toseat, try turning it 180 degrees).

When the machine is powered back on, the rollershould automatically rotate back into the normal posi-tion. It is a good idea to go into the Reports menu andprint a demo page or conguration page to make surethat the rollers are properly installed and positioned.

Variations in the procedure or other printer models:

CM2320 and CP2025: o get to the 2ndary Servicemenu rom the Ready state, simultaneously pressthe Let Arrow button and the Cancel button, thensimultaneously release them. Menu operations are asdescribed above. When the roller has rotated, rst un-plug the power cord, then place the power switch in theo position. Roller removal is as described above, butto access the rollers, just lit the ront o the printer. Donot tip it all the way back onto its rear surace, as thiscan cause contamination o the laser/scanner. Ater re-

placing the rollers, plug the power cord in rst and thenpower on.

CP1215: With the printer power o, press and holdthe Resume button. Continue holding this buttonwhile powering on. Wait at least 30 seconds (but lessthan 40 seconds) beore releasing the button. I this isdone correctly, the control-panel LEDs will cycle on

and o, indicating that the roller has moved to the re-quired position. Now power o. Roller removal proce-dures are as described above or the CM1312.

CP1515/1518: o get to the 2ndary Service menurom the Ready state, simultaneously press the LetArrow button and the Cancel button, then simultane-ously release them. Menu operations are as describedabove. Ten power o. Roller removal procedures are asdescribed above or the CM1312.
