Cleaning/Replacing the Printhead Cartridge
Cleaning
The Printhead Cartridge in the Colordyne 1600-S Printer is cleaned automatically each time the machine is
turned on or when the Level 1 Maintenance routine is performed by the operator. This can be found under
the Service Tab, Level 1 Maintenance in the Printer Driver. Level 2 and Level 3 Maintenance can be used
to more thoroughly clean or clear the Printhead.
If running the Maintenance Levels doesn’t help improve print quality, the Printhead Cartridge can be
cleaned manually. Open the Top Cover. Release and lift up the two latches (one on each side of the
Printhead Assembly) at the same time to raise the Printhead Assembly. Moisten the Printhead nozzles
using distilled water or deionized water (reference ASTM D5127-90 Type E-II Electronic Grade
Water) with a wet, lint-free cloth. Take care not to damage the copper contacts, the metal plate, or
the gold Printhead surface. Close and relatch the Printhead Assembly. Generally, when the ink supply
is adequate and the print quality remains poor, or when the built-in cleaning processes or manually cleaning
the Printhead has not helped the image quality, the Printhead should be replaced.
CAUTION
 Use electro-static discharge 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 dust, fibers, dirt and other
contaminants at all times.
Replacing the Printhead Cartridge
