ink box. The colors are marked as K (black), C (blue), M (red) and Y (yellow). The last

one without label is filled with cleaning fluid. Examples are shown in the following figure:

� Inject ink into the auxiliary ink tank

Please make sure that there is enough ink in the main ink bottle before injecting ink into

the auxiliary ink tank and the steps are as follows:

� Ensure that there is enough ink in the main ink bottle and conduct inspection of the

machine before starting.

� When you switch on inkjet printer for the first time, since the auxiliary ink tank is

empty, ink pumps of all colors will start working automatically and pump ink from

main ink box into auxiliary ink tank.

� When all the ink pumps stop working, it means all the auxiliary ink tanks have been

injected with ink.

� The transient buzzer sound during the process may be resulted from rather long

ink pump route and timeout.

� In the event of ink pump not working or prolonged alarming of buzzer, please switch

off the machine in time and examine. In case of failure to settle the problem, please

contact the local dealer or after-sales department of our company immediately.

� Inject ink into the print head

Since it is a very important operation to inject ink into the print head, please operate in

strict accordance with requirements. There are two critical operations, namely print

head cleaning and venting.

� Print head cleaning:

ink for the first time because protective liquid has been injected into the nozzle of

print head. You must wash off the protective liquid before injecting ink.

Maschinenvertrieb

LIYU DMS GmbH


In view of the power of cleaning fluid pump, it is suggested that you clean

a single print head every time. First, put the three-way valve of single print head

at purging state with other print head valves off, then unscrew corresponding

two-way valve, press purging button and make the cleaning fluid flow out from

two-way valve, clean the pipelines of this part. About one or two seconds later,

tighten two-way valve and make the cleaning fluid cascade out from nozzle for

about five seconds. clean other print heads according to the above method. Five

minutes later, clean all the print heads again as per the above method. Thus

print head cleaning is completed.

Print head cleaning operation involves cleaning fluid pump directly pumping

cleaning fluid to clean the print head, without any positive pressure, so

pneumatic three-way valve body operation is not required.

� Venting of print head:

Inject ink into the print head after cleaning print head. Venting operation shall

be conducted together with ink injection with the specific operation process as

follows:

1. It is also suggested that you conduct venting for every single print head,

that is to say, venting operation is conducted for only one print head every

time with valve body of other print heads off.

2. First of all, put the corresponding three-way-valve in working state and at

the same time place pneumatic three-way valve body in positive pressure

state.

3. Unscrew the corresponding two-way valve core to ensure smooth ink outlet.

Press positive pressure button and impress ink from the auxiliary ink tank

into the print head, then ink will flow out from two-way valve core. Observe

the ink flow state at the ink outlet. If the ink flows down vertically without

any bubbles around, you can tighten two-way valve so that ink will flow out

from the nozzle. (Tips: it may take long to impress ink for the first time with

such long pipelines, moreover, there is no sufficient ink in the auxiliary ink

tank, please hold on for a while after positive pressure so as to enable ink

supply system to refill the auxiliary ink tank and then continue positive

pressure).

4. Carry out the above operation for every print head in succession. Place all

three-way valves in working state after completing venting for all print

heads. Press positive pressure button and impress ink for all print heads

again, then complete ink injection of print heads.

5. Meanwhile, in case of bubble found in ink tube leading to print head, which

affects ink out of the print head, the above method can also be adopted to

carry out venting operation.

� Positive pressure ink

Maschinenvertrieb

LIYU DMS GmbH


Positive pressure ink refers to impressing ink of the auxiliary ink tank into the print head

by pressing positive pressure button to eliminate the air in the nozzle and flush through

the nozzle blocked not so seriously, as well as solve some common problems of printing

disconnection.

You can impose positive pressure to either a single print head or several or all print heads

with the specific operation steps as follows:

� Move the carriage to idle position, the far left of the machine.

� Make sure that the corresponding ink route three-way valve body for the print head

demanding ink impression is in working state. In case there are other print heads

for the same color, switch the corresponding ink route three-way valve body of other

print heads off.

� Turn the pneumatic three-way valve body to positive pressure state.

� Press positive pressure button and hold for a while, observe the ink out status of

print head and release positive pressure button when you feel ink flowing smoothly.

� Wait for two seconds and wipe the nozzle surface with clean non-woven fabrics.

� Negative Pressure Adjustment

Since negative pressure is an important factor for guarantying print quality, the operation

of its adjustment is crucial. The target of adjustment is to make ink form meniscus in every

nozzle printer. As long as sound meniscus is maintained, we can assure that ink droplets

are ejected at a high speed with few flight drops. Vacuum negative pressure system is

applied to this printer.

� Negative pressure system introduction

As described above, FH series products have the standard configuration of negative

pressure design for color print heads. If you also equip the product with ink degasser,

another line of negative pressure system will be added to provide high negative

pressure for ink degasser. Vacuum pressure switch is used to adjust all the negative

pressure of print heads and located on the left front console panel (see introduction

of “Left Front Console Panel”). Degasser is connected with vacuum negative

pressure components by means of high negative pressure switch. You may see it by

opening the left side door behind the machine. (See Article 12 of front view for details)

Maschinenvertrieb

LIYU DMS GmbH


The two operation methods in the above figure can be used for manual movement of X

and Y axis.

� Media positioning

The equipment provides origin orientation function and automatic detection function. You

may set these functions in the dialog box “system setting-origin setting”. You can also open

the dialog box “origin setting” by clicking the icon in LiyuPrint main interface.

� Origin orientation

Origin orientation function can locate the printing media position according to the

coordinate of X axis, thus realizing accurate positioning printing. The coordinate origin

is the original 0 point, that is to say, the carriage stops at the right-most position

of X axis. however, we usually don’t start printing from the original 0 point. Therefore,

this value can’t achieve precise and intuitive positioning. instead, certain test and

calculation shall be needed for the accurate positioning. You may realize the function by

setting the parameters in the following red frame:

Maschinenvertrieb

LIYU DMS GmbH


X 轴 X axis

原点位置 Origin position

获取 X 轴位置 Get X axis position

When you tick and enable any origin position, the origin printing function on LiyuPrint

main interface will be ticked. Then you can quickly select whether to use the origin

printing function by ticking or not ticking “origin printing” on the main interface.

Meanwhile, you can obtain the current coordinate of the carriage by getting the position

on certain axis on the interface after moving the carriage to the corresponding position,

and the coordinate acquired from operation is also relative to

the original 0 point position.

� Automatic detection

Select media origin in dialog box “origin setting” as the origin orientation type and

then select the quantity of materials to be detected, up to 6 portions of media

allowed, click “detection” button and the machine starts detecting. After completing

detection, the position and breadth of media will be displayed in the corresponding

place according to the material quantity that you select.

Origin printing

Maschinenvertrieb

LIYU DMS GmbH


The position and breadth are not necessarily accurate due to the sensor and other

reasons. In case of large deviations during printing, you can adjust to the relatively

accurate value through the dialog box “correction”.

Positioning operation after successful detection: there are two methods for

positioning after detection:

1. Switch positioning method to carriage origin and fill in the corresponding origin

location through the position and breadth of materials obtained.

2. Select the image position and print directly in the current interface. Here are three

typesetting modes provided, namely boundary printing, central printing and user-

defined. You can directly set the distance from the image to the boundary, as

Chapter 4 Maintenance and

Service

Contents of this chapter:

� Daily maintenance instructions

� Print head maintenance instructions

� Ink use guidelines

Maschinenvertrieb

LIYU DMS GmbH


� Daily Maintenance Instructions

1. Keep the working environment of the printer clean and ventilated, and clean dust

and ink on the printer periodically.

2. Keep the work surface clean. Every time before starting it up, check whether the

working board is cleaned, to avoid scatching the print head.

3. Inject lithium base greases into the slider by grease gun every forty hours operation,

to reduce its frictional resistance against the guide rail and extend its service life.

4. Maintain an appropriate belt tightening of the ink carriage timing belt, which can be

adjusted after removing the upper left end cap. After the adjustment, connecting

screws must be fixed tightly.

5. Every time after finishing refilling ink, make sure the cover of the main ink tank is

screwed tightly. Wipe off residual ink on the tank.

6. For positive pressure printing, after wiping the printhead, flash spray for around 10

seconds first before printing pictures, to achieve sound meniscus formed by ink

droplets in the nozzle.

7. The area around the orifice must be maintained clean,. No residual ink,dust or fiber

is allowed. Orifice shall not be scratched.

8. Since the ink and the cleaning fluid contain strong solvent, they mustn’t contact

electrical components and wires. Were ink or cleaning fluid spilled on them

accidently, they would be wiped off cleanly as soon as possible.

9. Clear liquid waste in the liquid waste box in time.

10. Every day before the startup and shutdown, it is recommended to print nozzle test

chart to check whether the nozzle is in normal condition. Provided that ink outflows

brokenly, press the ink or clean the nozzle to make it work properly.

� Print head Maintenance Instructions

As the core component, the print head is much expensive and sensitive, which requires good

maintenance. Otherwise, print quality and its service life would be seriously affected. Print

head maintenance instructions are as follows:

1. In using the printer, please use the ink appointed by the manufacturer. Do not change

the ink at will, or it might lead to malfunction of print head.

2. When the device stops running, maintenance methods of different sorts should be

adopted in accordance with the length of downtime:

� If printer downtime is within a working day and you are not willing to turn it off, it

should be set under the state of flash spray. Before the flash work, please confirm

Maschinenvertrieb

LIYU DMS GmbH


the status of print head. If it is not in a good condition, do the ink press operation

first.

� If the downtime is over 12 hours to a whole day, it is recommended that the valve

knob be screwed to the closed state, the ink carriage be stopped within the upper

left case, power be switched off, a layer of non-woven fabrics be embedded into

the wet protection tray, a small amount of cleaning liquid be injected into the wet

protection tray (non-woven fabrics should be drenched), and then the print head

can be moisturized with the wet protection tray, during which operation make sure

that the whole nozzle surface is in touch with cleaning liquid.

� If the downtime is within two days, the maintenance operations are the same as

the previous one. Meanwhile, non-woven fabrics in the wet protection tray should

be replaced every day, and new cleaning liquid should be injected into it (Cleaning

liquid needs to be changed, because components of moisturizing function within it

are easy to volatilize).

� If the downtime is over three days, clean up the ink within the print head following

its cleaning method, inject a little cleaning liquid into it (Leave some cleaning liquid

in the print head when doing the cleaning.)Meanwhile, moisturize the nozzle

surface with the wet protection tray according to method 2. In addition, replace non-

woven fabrics in the wet protection tray every three days and inject new cleaning

liquid into it.

3. Scrubbing the nozzle panel

� Every time when pressing ink with positive press or after cleaning the printhead,

scrub the nozzle panel. Wipe away residual ink and cleaning liquid on the nozzle

panel, to prevent it droping onto the printer or print media.

� When scrubbing the nozzle panel, dedicated non-woven fabrics should be used,

and make sure of its cleanness. Non-woven fabrics contaminated by dust, stain or

water, especially the one which has been used to scrub ink, should not be used to

wipe the nozzle panel, as ink on it can lead to a seriously blocked nozzle.

� Scrub the nozzle panel along a single direction rather than back and forth. Do not

scrub it with great strength, but touch it lightly, to avoid damage of nozzle surface.

� Dispose the used non-woven fabrics properly. Do not reuse it.

4. Adjusting the printhead condition in printing

� To guarantee print quality, please make sure every nozzle on the printhead is in

good condition, whose condition can be improved by pressing ink with positive

Negative pressure or doing the cleaning. The following items are very important to

guarantee the nozzle condition.

� The requirement of printer’s working environment shall be maintained well,

especially the temperature. The print head temperature shall be between 150C and

260C.Print quality may be affected if the temperature is below 150C or above 280C.

Maschinenvertrieb

LIYU DMS GmbH


� Make sure the print head exhaust completely, and no bubble remains in it.

� Adjust voltage and negative pressure of print head. A higher print head voltage can

improve the accuracy and color saturation of ink droplets, but it can cause the ink

outflow to be frequently broken as well.

� Ink Use Guidelines

1. Very Important: Prevent ink or any part of ink route from contacting water or any

solution containing water molecules, otherwise, gel may be produced, blocking

ink route or even print head.

2. Safety instructions:

Some chemical substances contained in ink are of very low toxicity and irritation, which

will irritate eyes and respiratory system and cause allergic reaction. Contact with ink can

be effectively reduced with sound ventilating device and personal protective devices.

When dealing with ink, acrylic gloves and work clothes should be worn. If ink spills onto

the skin, it should be washed immediately with soap-suds.

Eating, drinking and smoking are forbidden in the workspace.

3. Storage of ink:

Ink should be stored in sealed containers and placed in a cool, dry place with good

ventilation, free from exposure to strong light, with the proper storage temperature of

10℃ to 40℃. Though ink has the storage duration of 12 months, it is recommended to

use it up within 3 months. Pay attention to the production date when using ink. The

expired ink shall never be used. Because temperature has a great effect on viscosity of

ink, during change of seasons the different viscosity of ink may affect printing effect,

especially between winter and summer. In addition, ink manufacturers may adjust the

viscosity of ink according to change of seasons, hence you should select ink as per

actual ambient temperature.

LIYU DMS GmbH


I. Detailed Setting of Vacuum pressure gauge

Panasonic DP-101 digital Negative pressure switch is specially designed to

inspect and control vacuum, whose range is -100~-100KPa. 4-core interface is

applied to the control signal line and negative pressure gauge, which is

completely compatible with ink plate as well as SMC ZSE 30A. DP-101

Pressure gauge has two display screens, among which the main display shows

real-time value, while the minor screen shows the setting value.

( A ) Calibration of reference pressure of the pressure gauge ( When setting parameters for

the first time, the method below must be followed) .

The calibration of its reference pressure has already been completed when ex-factory, i.e.

standard atmospheric pressure is set as the datum zero. Normally, calibration is not

required.

When reference pressure changes due to some unpredictable factors, pressure calibration

is required. Otherwise, the displayed Negative pressure would deviate from actual

pressure.

Calibrating method: 1. Disassemble the air tube behind the pressure gauge,

2. Energize the pressure gauge, and some value will be shown

on its screen.

3. Press both ▲and▼ buttons for over 2 seconds at the same

time, and the main display will show the value 0.0.

Calibration of reference pressure has been completed.

( B) Working mode

The negative pressure gauge always display “RUN Mode” , while “Menu Setting Mode”

is used for basic setting, , and “PRO Mode” is used for advanced functionalities, . Under

“RUN Mode”, reference values can be adjusted, locked and so on. Under “Menu Setting

Mode”, basic settings, such as setting the output mode and switching between NO and

NC, can be operated. Under “PRO Mode”, advanced functionalities like Hysteresis

adjustment and copy function, can be set.

During the normal operation of “RUN Mode”, by pressing “MODE” button, the mode

switching button, for 2 seconds, it will switch to “Menu Setting Mode”, while by pressing

“MODE” button for 5 seconds, it will switch to “PRO Mode”.

( C) Output mode and seting

As for comparison output 1 and comparison output 2, output mode can be chosen among

EASY Mode as well as Hysteresis Mode and Window Comparator Mode.

1. Long press “MODE” button for 2 seconds to enter Menu Setting, and the main

1. Above values are common-used setting values. Specific values may be

sort of different.

2. The instantaneous display of pressure gauge at its being energized is not

in measuring status, but as follows:

It means that the pressure gauge will enter the working state after being energized for

5 seconds.

II. Adjustment of vacuum negative pressure value

Vacuum negative pressure is adjusted through vacuum pressure gauge. The negative

pressure value has been set while leaving the factory and users can make minor

adjustment of negative pressure value. Notes: When you set the negative pressure

gauge or change the setting value of negative pressure, be sure to unplug the

windpipe of the negative pressure gauge or make other air passage of negative

pressure system lead to the air outside, so as to prevent reverse suction of

auxiliary ink tank resulting from overpressure due to output of negative pressure

gauge.

The specific adjustment method is as follows:

1. Calculation of setting value for negative pressure gauge

A) Differential mode: threes values to be set for negative pressure gauge: Lo_1,

Hi_1 and P_2 with the unit Kpa, among which p_2=Lo_1=Hi_1-0.2.

For example, suppose Hi_1 = -50, -50-0.2=-50.2. then the setting value for p_2 and Lo_1

shall be -50.2. the final negative pressure value is between Lo_1 and Hi_1.

B) EASY mode: two values to be set for negative pressure gauge: P_1 and P_2

with the unit Kpa, among which p_2=P_1-0.2.

For example, suppose P_1 = -1.6, -1.6-0.2=-1.8. then the setting value for p_2 shall be -

1.8. the final negative pressure value is between P_1 and p_2.

2. Alteration method of setting value for negative pressure gauge

A) Differential mode: Press “MODE” button to enter setting state and the secondary

display shows Lo_1 once and then the value of Lo_1. Adjust the value by pressing ▲

or▼ button.

Continue to press “MODE” to enter setting state of Hi_1 and the secondary display

shows Hi_1 once and then the value of Hi_1. Adjust the setting value of Hi_1 by

pressing ▲ or▼ button.

Continue to press “MODE” to enter setting state of P_2 and the secondary display

shows P_2 once and then the value of P_2. Adjust the setting value of P_2 by


B) EASY mode: Press “MODE” button to enter setting state and the secondary display

shows P_1 once and then the value of P_1. Adjust the value by pressing ▲ or▼ button.

Continue to press “MODE” to enter setting state of P_2 and the secondary display

shows P_2 once and then the value of P_2. Adjust the setting value of P_2 by


Note: when adjusting the setting value of pressure gauge, the interval for every setting

value shall not exceed 0.2.
