 PRINT HEAD(s) (p.158)

Ink smear (printed area) The paper is contaminated by ink smear in the paper feed path. Check the PRESSURE ROLLER(s) for ink smudges, and clean it if any dirt is
observed.
Paper is rubbed against the printhead. Widen the platen gap.
Because the vacuum fan is not operating properly, the paper is not held flat during
printing.
Turn on the printer in the serviceman mode, and check whether the VACUUM
FAN(s) operates normally (p.234). If any abnormality is found, check the
connection status and replace the defective VACUUM FAN if necessary.
Drying ink is insufficient. Raise the heater temperature and make the print again.
Turn on the printer in the serviceman mode, and check whether the heaters operate
normally (p.234). If any abnormality is found, check the connection status and
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.
