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.
Manual Printhead Cleaning:
NOTE: We recommend the use of powder-free, nitrile gloves for this process.
As a last resort, if running the built-in “Clean Printhead” Levels doesn’t help improve print quality; the
printhead cartridge can be cleaned manually.
1. Wait for the printer to finish performing any maintenance
operations.
2. Open the Top Cover
3. Carefully open the Clamshell.
4. Clean the printhead nozzles. Dampen a lint-free cloth, with
deionized or distilled water. 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.
CAUTION: 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.
5. Carefully Close the Clamshell.
6. Close the Top Cover.
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.
