Cleaning the Printhead
The Printhead is cleaned automatically during shut-down, power-up, Mid Job Servicing and other circumstances.

Clean Printhead
” features.

Toolbox,
under the
“Service” Tab,
or from the
Touchscreen
, under the
“
Maintenance”
Menu drop-down.
If running these Cleaning Levels doesn’t help improve image quality, the Printhead surface can be cleaned
manually; as described below.
Tip:
Before you begin this process you may want to set the Media Thickness to 10 mm. This will give you more
room to get your hand under the Printhead. Be sure to make a note of your current setting, so you can reset this value
after you have completed the cleaning process.

Tip
: If you find that you need to clean the printhead surface frequently (more than a few times a day), to fix
color-mixing or nozzle firing issues; this may be an indication that there is a problem with automatic printhead
maintenance or capping. Please contact your service representative to have them inspect the printer.
In General, if the image quality remains poor (fuzzy/missing print, in same location), even after verifying that
all ink lines are filled with ink, running “
Full Clean Printhead
” and manually cleaning Printhead; this is an
indication that the Printhead may need to be replaced. It is recommended to replace the Wiper Roller when
replacing the Printhead.
CAUTION

shown circled in red. If they get bent
this will cause feeding issues.
Avoid contact with the Print Platen
(silver metal grate), to avoid scraping
(injuring) the back of your hand.
