Possible Causes for Short Print Cartridge Life
Cause Reason
Higher coverage rate than
listed in the specifications
The rate of coverage on the page significantly impacts the number
of pages per print cartridge. Heavy concentrations of ink and
higher print quality settings significantly reduces the number of
pages per print cartridge.
Pages contain graphics Generally, graphics use ink at a much higher rate than text. If
possible, print drafts of documents without the graphics.
Selected print mode Higher quality print modes use more ink than a draft print mode. To
maximize print cartridge life, print drafts of documents in
EconoFast mode, then print the final copies in Best mode.
Tape covering the bottom
of a high-capacity print
cartridge
The high-capacity print cartridge, part number 51626A, has two
pieces of tape: one tape covers the print cartridge nozzles and the
other tape covers the bubble generator. Removing tape from the
print cartridge nozzles without removing tape from the bubble
generator will result in a short print cartridge life.
Remove the tape from the high-capacity print cartridge and run the
print cartridge cleaning routine. If this does not restore the print
cartridge, replace the print cartridge and be sure to remove both
pieces of tape on all high-capacity print cartridges before installing
them in the printer.
Print cartridge is past its
expiration date
Replace the print cartridge. Use a FIFO (First In-First Out)
inventory process to minimize having a stock of expired print
cartridges.
