SECTION 4 - Maintenance

This section covers how to care for the Ink Cartridges, clear paper jams, replace the Sheet Separators, and perform

routine maintenance on the Printer.

Inkjet Cartridge

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. Approximate life of the HP 45 Inkjet cartridges, based on three lines of 20 characters

at 10-point size per address, is:

600 x 600 DPI

50,000 addresses

300 x 600 DPI

100,000 addresses

200 x 600 DPI

150,000 addresses

150 x 600 DPI

200,000 addresses

NOTE: These figures can vary depending on font selected.

To Replace Inkjet Cartridge:

1. Open Latch Lever to release Cartridge, then pull Cartridge up and out of Holder.

2. Remove new Inkjet Cartridge from packaging, taking care not to touch copper contacts,

metal plate, or gold printhead. Remove protective tape from Printhead.

3. With Cartridge’s Printhead pointing down, slide Cartridge into Holder and push down and

toward contacts in Holder.

4. Make sure Cartridge is seated in Holder, then close Latch Lever to secure Cartridge.

DO NOT force Latch Lever into place.

5. Repeat Steps 1-4 for 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

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.
