Section 4 – 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.
Inkjet Cartridge Maintenance
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.
The Approximate life of the HP 51645A Inkjet cartridges based on three lines of 20 characters at 10-point
size per address is:
High Quality 600 dpi 50,000 addresses
Standard Quality 300 dpi 100,000 addresses
Letter Quality 200 dpi 150,000 addresses
Draft Quality 150 dpi 200,000 addresses
NOTE: These figures can vary depending on the font selected.
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.
