replace the defective heater if necessary.
There is a foreign material or dirt absorbing ink around the PRINT HEAD(s). Check around the PRINT HEAD(s) for a dirt or foreign material, and remove it if
any.
The paper is buckling. Re-load the paper once the set heater temperature is reached.
Make sure the heater temperature is not set too high.
The color dots are smearing and mixing into each-other. The ink dots dry too slowly: try increasing the heater temperature.

Symptom Description Remedy/Points to be checked

Ink smear (backside) The backside of the paper is contaminated by ink smear in the paper feed path. Check the platen and PRESSURE ROLLER(s) for ink smudges, and clean them if
any dirt is observed.
C A U T IO N
If the PAPER SIZE CHECK in the PRINTER SETUP menu has been
set to OFF, the printer will print on the platen which results in the ink
smear, so be careful.

The ink does not have enough time to dry before it is rolled on the Take-up Reel. Try increasing the drying time between the passes, increasing the heater
temperature or put a fan in front of the printer to dry the media before it gets rolled-
up.

Horizontal banding Paper setting made in the custom paper menu is wrong. Correct the paper setting of the custom paper menu.
There is something wrong with paper feeding. Carry out the Paper feed adjustment (p.223).
Check the PF ENC SCALE for scratch, contamination, and correct it if any.
Check the PF ENCODER ASSY for contamination, and clean it if needed.
Replace the PF ENCODER ASSY (p.123).
The PRINT HEAD(s) has not been adjusted properly. Carry out the Head slant adjustment (p.212).
The PF belt’s tension is not proper. Carry out the PF reduction belt tension adjustment (p.222).
The parameter settings of the NVRAM may be incorrect if the banding occurs right Import the NVRAM parameters from the old MAIN BOARD ASSY.
after replacing the MAIN BOARD ASSY.
The print head has a defect. Replace the PRINT HEAD(s) (p.158).
There are too much blanks between the color dots. The ink dots may be drying too fast: try lowering the heaters temperature settings.
Vertical banding Adjustments have not been carried out properly. Carry out the head Uni-D/Bi-D Low/High gap adjustment (p.219).

The carriage unit cannot move smoothly. Check the CR BELT and the drive pulley for a defect.

Check whether the CR MOTOR is correctly installed. If not, install it correctly.

least a 150 cm distance from the print.

power circuit, so power is always supplied unless the power
cord is unplugged. Unless otherwise stated, be sure to unplug
the power cord and wait at least for one minute and 30 seconds
before disassembling or assembling the printer to prevent
electric shock and damage to the circuit.

„ Do not touch electrical circuit boards with bare hands as the
elements on the board are so sensitive that they can be easily
damaged by static electricity. If you have to handle the boards
with bare hands, use static electricity discharge equipment such
as anti-static wrist straps.
„ When reassembling the printer, make sure to connect the
connectors of the electric components or parts correctly and
securely. Use extreme care when connecting FFCs (flexible flat
cables). Improper connection of the FFCs, such as inserting
them diagonally into the connectors, could cause short-
circuiting and lead to breakdown of the electric elements on the
boards.

5.1 Overview
This chapter describes the Service Program software utility and the adjustment
procedures required after repairing or replacing certain parts.

5.1.1 Precautions
Always observe the following cautions whenever making an adjustment on the printer.

C A U T IO N „ Always refer to ?5.1.2 Adjustment Items and the Order by

Repaired Part? (p.186) and make sure to perform all
adjustments listed in the table in the given order.
„ Always read and follow the precautions given in each section
that explains each adjustment. Ignoring the precautions can
result in malfunction of the printer.
„ Do not use the Auto Take-Up Reel Unit when printing patterns
with the printer in the serviceman mode in order to prevent
back-feed troubles.

5.1.2 Adjustment Items and the Order by Repaired Part

The following table shows the required adjustments by repaired or replaced part and the order in which the adjustments must be performed. Find the part(s) you repaired or replaced
in the table, and carry out the adjustments in the indicated order.

NOTE 1: Blue cell: indicates that the adjustment is required when the part is once removed or replaced.
Red cell: indicates that the adjustment is required when the part is replaced.
2: The adjustments required for the Main Board differs depending on whether the NVRAM on the old board can be backed up or not.
3: When you repaired or replaced multiple parts, check the order of required adjustments using the sequential mode of the Adjustment Program.
4: When the FW update is required, first check the version of firmware currently installed on the printer, then update the firmware if necessary.
5: If a part is not listed on the table, there is no corresponding test or no need for any adjustment.
6: The tests can be performed before a part exchange to confirm a failure. They can be performed after an exchange to confirm the repair. The tests are not mandatory if
the parts operations can be confirmed in another way.
7: The numbers in the table indicate the order in which the adjustments must be done.

5.1.3 Description of Adjustments

The following tables describes the general outline of the adjustments.

NOTE 1: The meanings of abbreviations in the “What to Use” column are as follows.
SP = Service Program
SM = Serviceman Mode
MECH = Mechanical Adjustment can be performed. (In some cases, a dedicated tool for the adjustment or a commercially available tool such as a tension gauge is
necessary.)
2: When both SP and SM are checked, both can be used but we recommend using the service program as it is more user-friendly.

directly to the ink charge sequence.
Figure 5-42. Sequence
Examples of use:
„ In case the parameters in the NVRAM cannot be backed up during a main
board exchange, the parameters of the new board are reset to the ex-factory
situation so the washing sequence mentioned above will be executed the next
time the printer is turned ON. In case a washing sequence was no required
(ink already charged, no cleaning cartridge available, etc.), setting the flag to
“Off” can skip the washing sequence and go directly to the ink charge
sequence. If necessary, the ink charge sequence can be skipped by modifying
the ink charge flag.
„ In case a printer is washed and the sequence stopped before the ink charge
(preparation for a transport, refurbishment, etc.), setting the flag to “On”
allows having a washing sequence re-started again from the beginning the
next time the printer will be turned ON. (Reset to the same situation as the
factory shipment.)
