Section 5 –
Maintenance
This section discussed how to care for the inkjet cartridges, clear paper jams, replace
sheet separators, and perform routine operator maintenance to the AstroJet 1000
Printer.
The Inkjet Cartridge
The AstroJet 1000 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 50,000 addresses
Standard Quality 100,000 addresses
Draft Quality 200,000 addresses
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, 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.
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.
Storage
Short-term storage is defined as less than 2 days or less than 1 day in a hot and dry environment.
Long-term storage is defined as more than 2 days or more than 1 day in a hot and dry environment.
