Section 6 - Maintenance
This section covers how to care for the ink cartridges, clear paper jams, replace the sheet separators, and perform
routing maintenance on the printer.
The Inkjet Cartridge
The inkjet cartridges must be replaced when out of ink, when print quality is poor, or when purging and cleaning
have not helped the image quality.

NOTE: These figures can vary depending on the font selected.
To Replace the Inkjet Cartridge:
•
Remove the used cartridge from the cartridge holder by raising the latch lever to release the cartridge, and
then pull the cartridge up and out of the holder.
•
Remove the new inkjet cartridge from its packaging, taking care not to touch the copper contacts, the metal
plate, or the gold printhead. Remove the protective tape from the printhead.
•
The cartridges are held in place by a lever mounted on the inkjet cartridge holder. Release the lever by
raising it vertical.
•
With the cartridge's printhead pointing down, slide the cartridge into the holder and push down and toward
the contacts in the holder.
•
Make sure the cartridge is seated in the holder then close the lever to secure the cartridge in the holder. Do
not force the lever into place.
•
Repeat the above for the remaining cartridges.
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
