HP 950, 950XL, 951, 951XL ” Missing or Damaged Cartridge ” Errors

NOTE: On March 12th 2016, HP released a new printer firmware version (R1547A) which effectively “locks-out” the previous smart chip versions and may result in printer blocking errors such as “Older Generation Cartridge”, “Cartridge Missing or Damaged” or “Cartridge Problem” which prevents refilled cartridge usage on HP Officejet Pro 8610, 8615, 8620, 8625 and 8630 printer models. Click here for details on how to resolve this issue.


Providing the latest compatible chip versions are installed or for other printer models (HP OJ Pro 8100, 8600, 271dw, 276dw) which display printer/cartridge error message “One or more cartridges may be missing or damaged” or “Cartridge Problem” then either:

1. The chip has poor connectivity with the printer (i.e. possible ink residue on chip contacts – thoroughly clean chip’s surfaces with a damp towel).

2. The chip has been incorrectly placed onto the cartridge by the refiller (i.e. slipped to one side or installed upside down).

3. “Missing or Damaged” & “Older generation cartridge” alerts may also be caused by an incorrect chip version installation (i.e. Standard chip vs. XL chip) or the chip is incompatible with your printer model.  You can ask your refiller to verify chip positioning and that the correct chip type and color was installed.

Chip-ComparisonsNOTE 1: Your ink refiller (i.e. Costco US/Canada/UK, Fry’s Electronics, Sam’s Club, Auchan or University bookstore) should have installed a new replacement chip (green in color) onto the refilled cartridge(s) – see pictures below.  If the chip is missing then return to your refiller for replacement chip installation.

NOTE 2: HP 950, 951 ink cartridges which have new replacement chips attached to base of cartridge do provide ink level tracking but will give one simple nuisance message (i.e. “Non-genuine ink cartridge installed”, etc.) following initial cartridge installation. You may simply clear the message by pressing Ok.

NOTE 3: Verify the cartridge’s smart chip is positioned properly as shown below and ensure gold contacts are thoroughly clean with no visible damage to chip surfaces. Thoroughly clean with lint free towel and isopropyl alcohol as necessary.

“MISSING OR DAMAGED CARTRIDGE” ERROR CAUSES (chip has already been replaced)

If you have already returned to your refill store and received a 2nd replacement chip on ALL REFILLED INK CARTRIDGES, but the problem persists, then there are additional causes for this type of failure.  See below.

1) The internal built-in PRINTHEAD may have bent or damaged contact pins (the ink cartridges plug into the PRINTHEAD). Remove ink cartridge and inspect internal PRINTHEAD contact pins for visible damage (i.e. pushed in pins or broken pins – see photo below). When this problem occurs typically you will observe the error message “Missing or Damaged Cartridge”, though other ‘damaged’ messages may be observed (i.e.  “Ink Cartridge Failure”, “Cartridge Damaged”, or “The following cartridges are not intended for use in this Printer”) may appear depending on your specific printer model.

While the PRINTHEAD pins can be ‘carefully’ bent back into position using a very small flat head screwdriver (i.e. using eyeglass screwdriver or similar), the PRINTHEAD may need to be replaced with a new one if pin damaged is too severe. A replacement HP 950-951 PRINTHEAD (genuine part) can be ordered from Amazon.com

2) The replacement smart chip is incompatible with your HP printer model, incompatible with the latest HP software version, or incompatible to a newer HP Replacement-Chipprinter model. We suggest you return to your refill store and request a compatible replacement chip.




BYPASS OPTION

A bypass option is available for HP OJ Pro 8100, 8600, 271dw, 276dw printer models only, but you will need a 2nd set of spare ink cartridges (empty or full) in order to proceed.HP930-950-Chip-Removal_small

a) Obtain 2nd set of spare ink cartridge(s) – these can be used, empty or full. NOTE: You cannot use Setup cartridges from another printer.

b) Remove the replacement chip, or chips, from the refilled ink cartridge (chips are affixed with standard adhesive – gently pry chip off with tweezers). The original HP chip should be seen underneath – DO NOT REMOVE.

c) Perform the HP 950-951 Refilled Ink Cartridge Swap Procedure – see video here:  http://www.youtube.com/watch?v=uKfGFn1-yxI
