Remove/Replace Printhead Cartridge
IMPORTANT
TO ENSURE OPTIMUM PRINTING PERFORMANCE, IT IS RECOMMENDED TO
REPLACE THE WIPER ROLLER WHEN REPLACING THE PRINTHEAD.
Use this procedure to remove and or replace a Printhead that is currently installed in the Printer. If the printer does
not have a Printhead installed at this time; please refer to the section titled “Install Printhead Cartridge”.
Printhead Cartridge is a delicate precision device. Handle with extreme care to avoid damage and issues that could
degrade print quality.
CAUTION
•
Use electrostatic discharge (ESD) protection when handling.
•
Hold Printhead Cartridge by handles ONLY.
•
DO NOT touch ink couplings, nozzle surface or electrical contacts.
•
DO NOT unpack Printhead Cartridge until Printer is ready for installation.
Once unwrapped, delay in installing Printhead can compromise print quality
due to dehydration.
•

Protect Printhead from scratches, dust, fibers, dirt and other contaminants
at all times.
