Cleaning/Replacing the Printhead Cartridge
Cleaning
The Printhead Cartridge in the Printer is cleaned automatically each time the machine is turned on or when
the “Quick Clean Printhead” routine is performed by the operator. This can be found under the
Service tab,
“Quick Clean Printhead” in the Printer Driver or the User Interface in the Printer Toolbox. “Normal Clean
Printhead” and “Full Clean Printhead” can be used to more thoroughly clean or clear the Printhead.
If running the automated Cleaning Levels doesn’t help improve print quality, the Printhead Cartridge can
be cleaned manually.
1. Open the Top Cover.
2. Release and lift up the two latches at the same time
to raise the Print Engine Clamshell.
3. Moisten the Printhead nozzles using
deionized/distilled water (
reference ASTM D5127-90
Type E-II Electronic Grade Water ) and a damp, lint-
free cloth, wiping end to end. ( Gray strip located
below orange strip. ) Take care not to damage the
copper contacts, the metal plate, or the gold
Printhead surface.
4. Close and relatch the Print Engine Clamshell.
Generally, when the ink supply is adequate and the print quality remains poor, or when the automated
cleaning processes or manually cleaning the Printhead has not helped the image quality, the Printhead
should be replaced.
CAUTION
•
Use electrostatic discharge (ESD) protection when handling.
•
Hold the Printhead Cartridge by the handles ONLY.
•
DO NOT touch the ink couplings, nozzle surface or electrical contacts.
•
DO NOT unpack the Printhead Cartridge until the Printer is ready for
installation. Once unwrapped, delay in installing the Printhead can
compromise print quality due to dehydration.
•
DO NOT place an unwrapped Printhead on any surface before
installing. Protect the Printhead from scratches, dust, fibers, dirt and
other contaminants at all times.
