Description
Printing out [NOZZLE CHECK PATTERN], check nozzle eject-
ing condition.
Execute [CLEANING (A)] or [CLEANING (B)], if non-fire or
misalignment found. When still unsolved, clean the head and
around the restoration tub.
When outstanding is vertical streak on image, though head nozzle
is ejecting in well-conditioned or when replacement of head.
Remake head shading data and recopy to host computer.
Ink recycle system is installed in the printer, taking waste ink
appeared through head cleaning operation and put it back to reuse
for printing, ink cartridge, even if ink remains in the ink cartridge,
however, should be replaced with new one to prevent excessive ink
viscosity caused by water evaporating in the long time.
This is included in the customer's required maintenance, but
positive replacement at the periodic maintenance is preferable.
Check whether ink is running out from the overflow tube (1) into
the breath ink tub (2) or not. Replace the breath ink tub if necessary.
Remove and clean ink around the pump unit.
