HP 952, 952XL Ink Cartridges: Printhead Failure, Printer Failure or Ink System Failure Errors

NORMAL Cartridge Alerts

Upon installation of a refilled HP 952, 952XL or 956XL ink cartridge you will observe various ‘Used’, ‘Counterfeit’ & ‘Non-HP’ alert messages. Choose ‘Yes’, ‘Continue’ and/or ‘OK’ to bypass the various nuisance alerts. This will enable normal print operations.  With refilled ink cartridges, if you received an “Unauthorized ink”, “non-genuine ink cartridge may affect warranty”, “counterfeit ink” or similar message, you can simply ignore/dismiss these messages by pressing ‘OK’ once for each cartridge, so that the printer resumes its normal operation. If you do not have the full printer driver version installed it is possible that you may not be able to see the cartridge error bypass option – you may need to install the complete printer driver version for your computer’s operating system.

ABNORMAL Cartridge Alerts

1) For the HP printer error(s): “Printhead Failure“, “There is a problem with the ink system” or “Ink System Failure“, we suggest you return to ink refill lab and request to have the cartridge’s chip evaluated and request to have the ink cartridge weighed to ensure it has an adequate amount of ink inside (i.e. if air is ingested into the internal PRINTHEAD this will usually cause a ‘Printhead Failure’ error condition, or similar).

0_Ink-System-Failure_HP-950-951-(8600)_sm

2) For the HP printer error “Problem with Printhead” or “Depleted Ink Cartridges“, then one (or more) of the refilled ink cartridges is likely empty and will need to be checked for proper ink fill volume/weight. Return cartridge(s) to your ink refill lab for evaluation.

If you have a grams weight scale you can perform the ink weight checks yourself:

HP      gwt. Full 75% 50% 25% Empty
952/setup blk 81.2 72.9 64.5 56.1 47.8
952xl black 102.7 89.4 76.1 62.8 49.4
952/setup cy 40.5 36.8 33.1 29.4 25.6
952xl cyan 55.9 48.8 41.7 34.6 27.4
952/setup ma 40.2 36.6 32.9 29.2 25.5
952xl mag 56.0 48.9 41.8 34.7 27.5
952/setup yl 39.5 36.1 32.7 29.3 25.8
952xl yellow 53.8 47.2 40.6 34.0 27.4
956xl black 130.5 109.9 89.3 68.7 48.1

 

3) For HP printer error condition “Alignment Failed” or “Incompatible Printhead” which is preventing printing, this could be a Printhead nozzle firing problem (with one of the colors), possible electrical connectivity issue between carriage and the PRINTHEAD assembly (i.e. dirty contacts or poor contact) or an internal electrical failure of the built-in PRINTHEAD assembly.* These types of printer errors typically do not have anything to do with the ink cartridges as this is more of a PRINTHEAD issue in most cases.*

DIAGNOSTIC CHECKS & TESTS:

 

1) Plain paper should be used for testing to ensure this is not a paper sensing issue. However, depending on how much you have printed to date, there could be ‘ink mist’ interfering with the media sensor/sensing optics (a very common problem in the large format printer models). Run thru our quick checklist to evaluate all variables that may be causing the issue: HP 952 Cartridge Troubleshooting

 

2) Remove ink cartridge and inspect cartridge’s smart chip surface (i.e. gold contacts) – check for scratches or ink residue. Verify cartridge’s smart chip position is correct – see pictures of cartridge chips at following link for reference: HP 952 Cartridge Troubleshooting

– Retest printer using plain paper or a different paper type (standard bond is suggested).

– Replace cartridge if suspected to be physically damaged.

– If smart chip position looks incorrect, return ink cartridge to your refiller for evaluation and/or chip replacement.

 

If the HP 952, 952XL ink cartridge error condition still persists, verify none of the internal PRINTHEAD pins, which the ink cartridges have direct contact with, are bent or broken. Click here for details: HP 952 Cartridge Troubleshooting

NOTE: An error could also be caused by a slipped chip issue. We suggest you remove the refilled cartridges and inspect cartridge’s smart chips for proper placement, alignment….ensure no DEEP scratches are visible on chip surfaces (see photo at right). Return cartridges to refill lab if any of these conditions are present. Refer to photos here: HP 952 Cartridge Troubleshooting

 

3) Perform Tap 41 (43) PRINTHEAD Health Diagnostics Test, along with supporting service level/diagnostic tests (NOTE: service menu access procedures do vary by HP printer model, refer to HP printer diagnostics document, pages 45-47, to view normal display messages,  https://www.inkjet411.com/?page_id=1813  )

 

Tap 41 PRINTHEAD Health Diagnostics (NOTE: the following procedure applies to touchscreen printer models only):

  3. Use arrow keys to advance to the ‘Special Reports’ Menu. Select OK.
  4. Use arrow keys to advance to the ‘print mech button tap’ menu. Select Ok.HP-OJPRO-8600_Print-Mech-Button-Tap-menu_small
  5. ‘code = 0’ will be displayed. Use arrows keys to change value to ‘41’ (i.e. press and hold right arrow key).
  6. When ‘Code = 41’, select ‘OK’. The diagnostic test pattern will print.
  7. Check the 4th line at the top of the printed report; an electrically good/stable PRINTHEAD will state “Pen Status: Pen OK”………if any other message is displayed then the PRINTHEAD may have failed and may need to be replaced. Re-seat PRINTHEAD and/or clean rear electrical contacts and repeat ‘Tap 41’ test to verify connectivity is not the issue.*

* An internal electrical failure of the PRINTHEAD generally has nothing to do with refilled ink cartridges as failures will normally occur over time and with average print use. The PRINTHEAD assembly is a separate electronic unit in which the cartridges plug into and feed ink into.**

4) To rule out printer/cartridge connectivity (i.e. PRINTHEAD assembly interface/connection) issues please ensure you have followed all steps on HP’s support page – this includes PRINTHEAD removal and thorough cleaning of the electrical surfaces on the PRINTHEAD and on the CARRIAGE ASSEMBLY:

http://www8.hp.com/h22157/video-gallery/us/en/customer-care/printers-and-all-in-ones/replace-ink-and-toner/2286857593001/replacing-the-printhead—hp-officejet-pro-8600-e-all-in-one-printer/video/

 

5) Remove all 4 ink cartridges, then remove the internal PRINTHEAD and thoroughly clean rear electrical contacts and carriage electrical contacts. Inspect ink foam ports to see if they are ‘wet with ink’…this will confirm whether ink is being pulled into the PRINTHEAD or not. If the ink foam ports are completely dry (no significant amount of ink present when blotted with a paper towel, etc.), then the PRINTHEAD is likely considered too dry to support proper ink flow and subsequent printing operations. Refer to PRINTHEAD removal process at HP.com (see link above).

 

6) If after thorough electrical contact cleaning the problem persists, you may need to replace the PRINTHEAD ASSEMBLY (i.e. Amazon), however, as a last ditch effort, you might want to perform a hot water flush on the PRINTHEAD:

  1. Remove all ink cartridges from the printer.
  2. Remove the PRINTHEAD – for most printer models you will need to pull up on the lever adjacent to carriage assembly to unlock the printhead (NOTE: printhead cannot be easily removed on 8100 series printer models as partial printer dis-assembly is required). Lift printhead straight up to remove.
  3. Over a sink, run warm tap water directly into the 4 ink ports for approximately 2 minutes – this will effectively saturate the foam ports and blow ink out/thru the nozzle plate bottom.
  4. Using a lint-free towel, remove water from rear/bottom electrical contacts. Ensure printhead electrical contacts and exposed surfaces are fully dry.
  5. Install the printhead into the printer. You may observe a “Replace Printhead message” so you will need to cycle printer power by turning printer off and then on to clear the error.
  6. Install ink cartridges and retest printer. You should observe a New PRINTHEAD alert message followed by an approx. 4-minute preparation countdown prompt.
  7. If permissible, activate the ‘Clean Printhead’. This can be done from the printer’s control panel or software printer driver (for example, by selecting ‘Tools’ – ‘Clean Printhead’, or similar).
  8. If you have reached this point of the troubleshooting and all the previous troubleshooting steps did not work, then the printhead is likely damaged or at end of life* and may need to be replaced.

 

NOTE: If you are unable to remove the PRINTHEAD assembly then consult your User’s Guide for specific instructions or refer to HP.com.

 

7) If this does not remedy the problem, then you may have a defective PRINTHEAD in the printer (worst case scenario), unrelated to the refilled cartridges.**

ADDITIONAL NOTES:

 

However, if you observe missing colors or poor image quality then air may have been accidentally ingested into the ink lines between the cartridge(s) and PRINTHEAD. To recover from this problem, you will have to run the “Clean Printhead” procedure 2-3 times to recover the ink system. Watch the video on the HP support page which describes some of the common issues you may encounter with refilled ink cartridges. This type of problem is common and completely recoverable.

NOTE 1: The HP 952 ink-series printer models have an electronic PRINTHEAD within the base of the carriage assembly (responsible for pulling ink from the 4 ink cartridges and then firing the ink droplets onto the paper) – these will eventually fail depending on print usage type and printer duty cycle (i.e. generally rated for an estimated 20,000 printed pages over printer life, but the consumer average may typically be closer ~10,000 pages over life). The printhead is replaceable and genuine parts can be ordered from Amazon, or similar.  For information on how the PRINTHEAD functions, please watch the following video: https://www.inkjet411.com/?page_id=2054

HP-950-951-Printhead_sm

**Typically the printhead should not reach it’s end-of-life until after a minimum of 8 or more complete sets of cartridge changes. While some printheads may last 20,000+ pages others may only last 4000 pages, actual results will vary. The printhead will eventually fail in time due to an internal micro-electronics failure, due to the following leading factors: general customer print usage and printer care, printer duty cycle (i.e. # pages printed per month), printing frequency (i.e. time between each print job), print mode (i.e. draft vs. normal) and content printed (i.e. photos vs plain pages) and color mode (black and white only vs. color/greyscale printing).

https://www.inkjet411.com/?page_id=2934

 

Paper types used (i.e. plain paper, photo papers & matte/heavy bond papers) and paper edge curl (i.e. duration in printer and/or exposure to low relative humidity) can also quickly lead to premature printhead failures due to physical ‘head strikes’ of the paper edges making repeated contact with the printhead nozzle plate surfaces.

 

Printhead Life

The built-in PRINTHEAD will eventually fail over time with usage and age (may or may not be replaceable depending on printer model – see User Manual)

NOTE: A compatible (clone) ink cartridge can be problematic; the embedded smart chip may not provide reliable printer-cartridge connectivity once installed. Compatible/clone cartridges are typically purchased on-line or at select retailers (i.e  sold under a different label than the regular HP cartridge packaging and are typically manufactured overseas) and is essentially a “clone” of the HP original/genuine ink cartridge (if cartridge is original/genuine then the official HP trademark logo will be displayed on the side label of the ink cartridge). For the best refilling experience, only use HP original/genuine ink tanks which display the HP trademark logo on label/side of ink cartridge. NOTE: Our retail labs will NOT refill non-genuine HP 952/956XL ink tanks.
