4085-001 Cleaning Printheads The Clean Printheads operation is used to clean and maintain the printheads. This mechanical operation performed by the print engine is recommended when print quality becomes degraded. There are two classes of cleaning that can be performed: • Short Clean is a "spit and wipe" cycle followed by a Print Quality test page. Short Clean should be used first. • Long Clean consists of printing a Print Quality test page, prompting the user for "bad" printheads, selective priming of "bad" printheads, printing the Print Quality test page, and then prompting the user to see if print quality has improved. If print quality improves and is acceptable on all printheads, the Ready prompt appears. If print quality has not improved, the process repeats. Long Clean can result in the disposal of a significant amount of ink and as such should be used only when Short Clean does not correct the problem. Diagnostic Aids 3-7
