Printheads 1 and 3 Printhead Reservoir Fill Error RAP or the 93-553-00 to 93-556-00 and 93-
561-00 to 93-564-00 Printheads 2 and 4 Printhead Reservoir Fill Error RAP.
The purge line
errors are found and corrected.
YN
Check the printheads for evidence of ink drooling from the printhead jetstack area, for
example: printhead not turning off, ink pouring out of the printhead, ink all over the drum
or waste tray overfilling. If necessary, install a new printhead, PL 91.20 Item 2 or PL 91.25
Item 2.
NOTE: Drooling may occur after a purge is completed and the printhead will continue to
‘ooze’ small amounts of ink out of the printhead. Drooling may also occur at initial warm
up and effects all four printheads and does not continue after the purge cycle.
This may eventually lead to clogged jets and may stain the face plate.
Perform SCP 5 Final Actions.
