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.
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
after replacing the MAIN BOARD ASSY.
Import the NVRAM parameters from the old 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.
