Replacing the Inkjet Cartridge:

Remove the used cartridge from the pen stall by raising the latch lever to release the cartridge, then pull the cartridge up and out of the pen stall.

Remove the new inkjet cartridge from its packaging, taking care not to touch the copper contacts, or the nozzle plate. Remove the protective tape from the printhead

The cartridges are held in place by a lever mounted on the pen stall. Release the lever by raising it vertical.

With the cartridge’s nozzle plate (printhead) pointing down, slide the cartridge into the pen stall and push down and toward the contacts in the pen stall.

Make sure the cartridge is seated in the pen stall then close the lever to secure the cartridge in the pen stall. Do not force the lever into place.

Reset the Ink Level Monitor for this cartridge position. See “Ink Level Monitor Reset

Repeat the above for the remaining cartridges.

CAUTION

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.
