Cleaning Print Head Nozzles
This section explains how to handle print heads.
• Head cleaning consumes ink. Perform this function only when necessary.
• Perform no other operations during head cleaning.
• Cleaning may be incomplete if ink in a cartridge gets too low or runs out during cleaning.
• An error will occur and head cleaning will not be possible if:
• There is a misfeed.
• One of the machine's covers is open.
• The machine is performing maintenance operations.
• The machine has run out of ink.
• The waste ink bottle is full.
• The service call icon is displayed on the display panel.
About Head Cleaning
There are two types of head cleaning. Perform head cleaning according to the result of test printing.
• Nozzle Cleaning: Low
If there are bending lines or clogged nozzles in the test printing result, perform Nozzle Cleaning:
Low.
• Nozzle Cleaning: High
If there are missing lines or ink has mixed, perform Nozzle Cleaning: High. Nozzle Cleaning: High
cleans the print heads more powerfully than Nozzle Cleaning: Low. Perform [Nozzle Cleaning:
High] also in the case of a media jam (scratches on the media) and extended decap. The ink
consumption for Nozzle Cleaning: High is greater than that of Nozzle Cleaning: Low.
If the printing problem is still not resolved even after performing Nozzle Cleaning: Low three times,
perform Nozzle Cleaning: High and clean the cap. See "Cleaning the Caps", Requests for Daily Care
and Maintenance. If the problem is still not resolved, see page 184 "When You Want to Clear Nozzle
Clogging".
