Printhead Nozzle Area
WARNING : Be careful not to damage the
“star rollers” when wiping the printhead.
These rollers are designed so they can roll
across a wet image, without damaging the
image. If the rollers are bent, they will not
turn free; causing media feed issues
(jamming) and possible damage to the
image or media.
Using the Clean Printhead Button:
A “Level 1 Maintenance” can be activated by pressing the “Clean
Printhead Button”, located on the print engine; as shown. The wiper
roller, in the Service Station, will perform a quick cleaning of the
printhead nozzles.
Manual Printhead Cleaning:
NOTE: We recommend the use of disposable gloves for this process.
As a last resort, if running the built-in User Maintenance Levels doesn’t help improve print quality; the
printhead cartridge can be cleaned manually.
1. Carefully open the clamshell.
2. Clean the printhead nozzles. Dampen a lint-free cloth, with
deionized or distilled water. Keep the printhead nozzle area facing
down and gently wipe the printhead nozzle area, from end to end,
in one direction and in one fluid motion. You can repeat this
process a few times, but only wipe in one direction.
NOTE
: The use of deionized water (reference ASTM
D5127-90 Type E-II Electronic Grade Water) is preferred; however it is acceptable to use distilled
water if deionized water is not available. Do NOT use tap water or paper towels to clean the
printhead nozzles. Doing so may cause damage to the printhead cartridge and possible
contamination to the ink system.
3. Carefully Close the Clamshell.
CAUTION: To prevent damage, hold onto, then lift and release both latches when closing. If you
force it closed without holding the latches open, you will eventually damage the latches and
clamshell switch (door switch).
