Cleaning/Replacing the Printhead Cartridge

Cleaning
The Printhead Cartridge in the RENA Mach 5 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 or the User Maintenance Levels in the Printer
Toolbox. Level 2 and Level 3 Maintenance can be used to more thoroughly clean or clear the Printhead.
If running the automated Maintenance 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 Printhead Assembly.
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 Printhead Assembly.
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.
•
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.
