4-4. Special Notes on Servicing
(1) Service test print
Be sure to perform the service test print after replacement of the logic board, valve unit, or ASF unit.
If the printer is started in the user mode without performing the service test print after replacement of the
logic board (or the valve unit in some instances), the reactor error (8 times of cyclic blinking of the Alarm
and Power LED's) occurs.
< Purpose of the service test print >
Before service test printing, Clear ink is supplied to see if the sensors inside the valve unit operate
properly or the tubes are securely connected. (If a sensor is faulty or a tube is disconnected, too much
Clear ink will be supplied, causing leakage of Clear ink.)
< If nothing is printed in service test printing >
When the valve unit sensor detects a problem, nothing is printed in service test printing (no error
indication).
In that case, perform the following, then print the service test pattern again:
1) Confirm that the tubes are securely connected.
2) Replace the Clear ink tank.
3) Replace the valve unit.
(2) For smeared printing, uneven printing, or non-ejection of ink
When smeared printing, uneven printing, or non-ejection of ink occurs, print the nozzle check pattern to
determine whether the print head is faulty or not.
< Procedures >
0) Using the tool print head, confirm that the test printer (to be used to examine the print head in question)
operates properly, then install the print head in question in that test printer.
1) Print the nozzle check pattern (in the user mode or in the service mode).
2) If there is a missing portion in the printed pattern, perform the print head cleaning (2 times at the
maximum), and print the nozzle check pattern again.
3) If the problem persists even after the print head cleaning is performed 2 times, perform the print head
deep cleaning, then print the nozzle check pattern again.
4) If the problem is still not resolved, i) turn off the printer and leave it for 24 hours or longer, ii) perform
the print head cleaning, and iii) print the nozzle check pattern again.
5) If the problem still persists after steps 1) to 4), the print head may be faulty. Replace the print head.
