Technical information

should bring the cartridge back to the Costco Photo Department and have it re-programmed (or

replaced). Also, request to have it weighed to ensure that it was properly filled.

In the interim, please verify the first two items below are not causing the issue:

ADDITIONAL CARTRIDGE RECOGNITION FAILURES/CAUSES:

NOTE: assumes smart chip has already been reprogrammed or replaced

We suggest you verify that there is no ink residue on the surface of the smart chip (at rear/lower side of

ink cartridge) – refer to 4

picture at the following link: http://inkjet411.com/?page_id=973

The failure to recognize an ink cartridge(s) could either be a possible Cartridge connectivity,

PRINTHEAD* connectivity or an end-of-life PRINTHEAD issue. We suggest you remove all the ink

cartridges and thoroughly clean BOTH PRINTHEADS manually along with cartridge chip contact surfaces

(located on bottom-rear side of each ink cartridge). Clean all electrical contacts, including those inside

the printer which mate to the PRINTHEADS. Reinstall both PRINTHEADS and cartridges and retest.

Ensure an "expired ink cartridge" alert state is not causing the issue, refer to this page on how to check

& bypass: http://inkjet411.com/?page_id=1384

---- If you observe an “Expired xxxx ink cartridge” alert or message, this error may be bypassed

by performing the following:

a. Press and HOLD the Power button.

b. Press Resume button 3 times.

c. Release the Power button

If, following HP 88 cartridge re-programming and complete cartridge/printhead/printer manual

electrical contact cleaning, the cartridge alert message(s) continue, then you may have a damaged

PRINTHEAD* (there are two printheads inside the printer) which may require re-priming or replacement

depending on problem symptoms. PRINTHEADS can be ordered on-line from either an authorized HP

reseller or you can purchase knock-off PRINTHEADs from Chinese vendors (i.e. Alibaba.com or similar).

* The HP 88 ink-series printer models have two electronic PRINTHEADS (each of these electronic devices

are responsible for pulling ink from the ink cartridges and then firing the ink droplets onto the paper) –
