*While the HP 02 permanent printhead is rated for ~20,000 pages, the average life is typically less than
10,000 pages due to infrequent use and age of electrical components. This is just part of the natural
degradation of this printer writing system over time & with usage (i.e. image content/print density). The
printhead is the core electronic engine behind firing the drops onto the paper...not the ink cartridges
(these are just plastic ink holding tanks).
You can verify PRINTHEAD electrical performance by running the Tap 41 diagnostic test from the Service
Menu â depending on your printer model, two procedures are provided here (see Advanced HP Printer
Diagnostics): http://inkjet411.com/?page_id=1372

CANON âTANKâ UNRECOGNIZED CARTRIDGE ERROR (3,5,6,8, 220,221, 225,226)
Regarding your recent inquiry about the Canon 225 cartridge error condition associated with your Canon
MX892 printer, the cartridge probably has a defective chip which was mis-programmed during the refill
process. We suggest you take the suspect ink cartridge back to Costco and request they either re -
program the chip since it is not being recognized....however, let's run just a few simple checks first to
screen out all variables....
1) Remove the ink cartridge from the printer and carefully inspect the small chip on the bottom/rear
side of ink cartridge - ensure there is no ink residue on gold contact surfaces. Clean contact surface with
an isopropyl alcohol dampened lint-free towel or cloth.

2) Otherwise, we suggest you bring the cartridge, or cartridges, back to the Costco Photo Department
and have the cartridge chip re-programmed. Also, request to have it weighed to ensure that it was
properly filled.
3) If this does not remedy the problem, then we suggest you remove the ink cartridge and thoroughly
inspect the PRINTHEADâs electrical contact points for ink residue, etc. Reinstall cartridge(s) and test.
Refer to User Manual for instructions on PRINTHEAD removal/replacement subsequent contact
cleaning.
NOTE: Canon 'ink tank' based printer systems are the most reliable of all inkjet printer systems when it
comes to refilling and ease of use. Unfortunately in this case, something went wrong. Please
