� Add ink and fill the print head with ink

� Install ink and cleaning fluid

Directly place the cleaning fluid bottle and ink bottle with enough ink in the lower right

box of the machine according to the color order marked on filters (placement is shown in

the following figure), and insert the ink tube of corresponding color into the ink bottle.

Note: In the following figure, K, C, M and Y stand for corresonding four colors of ink, and F

is the cleaning agent.

� 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.

� Start the inkjet printer. You can either reset the machine or not reset the machine by pressing

motor power button and cutting off motor power line.

� After the inkjet printer starts, ink pumps of various colors will set to work and pump ink

from the main ink bottle to the 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:

The new print head must be purged with cleaning fluid before being injected with 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. Otherwise, the

printing quality of print head will decline. Cleaning method of new print head:

a Properly connect all the wires of the machine (including print head wire), start

the machine and press high voltage button of the print head.

b 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. c

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

d Wait for five minutes and clean them once again.

� 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.

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

tube of ink outlet until there is no bubble in the ink tube, then tighten two-way

valve and make ink flow out from the nozzle. (Tips: it may takes 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

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:

� Stop the ink carriage at the cleaning position, namely the far left of the machine, and ensure

that the liquid receiver tank has been put in place under the bottom plate of print head.

� Turn the three-way valve of the print head demanding ink to working state, with other valves

off.

� 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.

The adjustment of negative pressure is as follows.

� Vacuum Negative Pressure Adjustment

The intensity of vacuum negative pressure can be adjusted by the vacuum pressure gauge.

Panasonic DP - 101 vacuum pressure gauge is selected to control negative pressure for this

printer. The vacuum pressure gauge is operated on the right button panel. The following picture

demonstrates the negative pressure system.

For detail settings, please refer to appendix 1.



Mark

Number

Name Function

1 Vacuum pressure system To provide steady negative pressure for print head in accordance with the settings of the

vacuum pressure gauge.

2 Positive Pressure gauge To maintain pressure within the setting range when ink is pressed with positive pressure.

1. Calculation of the setting value of negative pressure gauge:

In total, two values are required to be set on the negative pressure gauge, namely,

P_1,P_2，whose unit is Kpa. Among them, p_2 = P_1 - 0.2 . For instance, P_1is set

to be -1.6；-1.6 - 0.2= -1.8；the setting value of p_2 should be -1.8 and the final

negative pressure value lies between P_1 and p_2.

2. Operation to change the setting values of negative pressure gauge:

a: Press “MODE” button to enter the setting state-the minor screen will show Lo_1

for one time-then the value of Lo_1will be displayed- adjust its value through ▲or

▼button.

Press ”MODE” button again to enter the setting state of Hi_1- the minor screen will

show Hi_1 for one time and then shown its value, - adjust the value by pressing ▲or▼

button.

Press ”MODE” again to enter the setting state of P_2- the minor screen will show P_2

for one time - showing its value- adjust by pressing ▲or▼ button.

b: Press “MODE” button to enter the setting state, and the minor screen will show P_1

for one time-and then will show its value-adjust its value through ▲or ▼button.

Press ”MODE” again to enter the setting state of P_2, and the minor screen will shows

P_2 for one time and then show its value– adjust its value by pressing ▲or▼ button.



Caution: When adjusting the setting values of the pressure gauge, the interval between your

settings should not exceed 0.2 at best.

Operation is set as an example as follows to demonstrate the setting process.

The vacuum pressure gauge shows normal negative pressure

The Pressure gauge shows Lo_1 and its current setting value. Adjust its

into the calculated one value following the above - said method by using the up/ down arrow.

� Ink use guidelines



� 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 20

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

in the nozzle.

7. During the interval of printing pictures, printer please keep the print head under the

state of flash spray, in order to guarantee a smooth nozzle.

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

allowed. Orifice shall not be scratched.

9. 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.

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

11. When the suck-back phenomenon occurs to the printer and ink appears in the air tube

of the minor ink cartridge, the printer should be stopped immediately to discharge the

ink from the air tube and the waste liquid tank (safety bottle) and replace the air tube

with a new one.

12. 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 or authenticated

by KONICA. 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 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 print head,

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.

� To guarantee print quality, please make sure every nozzle on the print head 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

300C.Print quality may be affected if the temperature is below 150C or above 300C.

� 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. 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.

2. Storage of ink:

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

no long-period exposure to light (including indoor sunlight, illumination light, etc ) and with

temperature of 10 ～ 40 . Although ink has a storage duration of 24 months, it

recommended to use it up within 12 months. Pay attention to the production date. Out-of-date

ink cannot be used.
