Cleaning the Inkjet Cartridge (Printhead)
To maintain good print quality it is important that the printheads are kept clean. During the
printing process ink spray, paper fibers, and dust can cause a build-up on the cartridge nozzle
plate (printhead). This build-up will eventually degrade the print quality. If you begin to notice
problems with the print quality, or if you want to help prevent imaging problems before they
occur; the nozzle plate of the cartridge should be cleaned with a damp, lint-free, non-abrasive,
cloth, such as Rena Cartridge Wipes (part # 2023).
Cloth should be: Cloth should not be:
 Soft
 Fiberless
 Moist with Water (Distilled is best)  Abrasive
 Made of small fibers
 Dry or containing chemical additives
 Place a drop of distilled water near the edge of the
Cartridge Wipe cloth.
 Start by placing the cartridge onto the damp area of
the cloth.
 Using a small amount of downward force, slowly pull
the cartridge from the damp area, across to the dry
area of the Cartridge Wipe, while slowly decreasing
the amount of downward force.
 Repeat this procedure a few times. Make sure you
only clean the cartridge in one direction. Either from
the front of the head to the back of the head, or from
back to front.
 It is recommended that you perform a purge, just before starting to print again.
NOTICE
NEVER SHAKE, DROP, OR HIT THE CARTRIDGE AGAINST THE PALM OF YOUR HAND OR
ANY OTHER HARD SURFACE. SHAKING THE PRINT CARTRIDGE DOES NOT “MIX” THE
INK AND HITTING THE CARTRIDGE AGAINST A HARD SURFACE DOES NOT CLEAR THE
NOZZLES BOTH OF THESE ACTIONS ACTUALLY HURT THE PRINT QUALITY BECAUSE
THEY ALLOW BUBBLES TO FORM NEAR THE INK FIRING CHAMBERS. THESE BUBBLES
PREVENT THE NOZZLES FROM FIRING CAUSING WHITE STREAKS IN THE PRINT IMAGE.
Purging the Nozzles
If the inkjet cartridge sits inactive for a period of time, ink may dry in the nozzles. Normal
printing may not remove these “ink plugs” from the nozzles. White streaks will then show up in
the printed text or graphic. In order to obtain better print quality, these ink plugs need to be
forced out or purged. This can be done from the Printer’s Control Panel; as follows:
1. Take the printer Off-Line.
2. Press the MENU key momentarily.
3. Use the + key to scroll to the “PURGE” feature and then press the ENTER key. If the
rest of the system is setup to run; a piece of media will feed and a purge pattern will be
printed onto it. If desired; press ENTER again to print an additional purge image.
