What kind of error messages are customers seeing when impacted by this firmware issue?
If the customer has accepted the firmware upgrade and are using older versions of the smart chip that are not compatible with the new firmware, they will see lockout error messages such as “Cartridge Problem”, “One or more cartridges are missing or damaged” or “Older generation cartridge” which prevents HP 950-951 refilled cartridge usage.
Please be aware that printer error/message can jump from color to color; all refilled cartridges may be suspect.
If the HP 950/951 cartridge error condition still persists following a firmware update, It is possible that 1 of the 4 cartridges has an older revision smart chip installed on it (i.e revision ‘G’ or ‘J’) and this could be causing the issue; you must have a matching set of chips on all 4 ink cartridges, all must be at revision ‘ L J ‘ in order for the printer to function correctly. In addition, verify none of the internal PRINTHEAD pins, which the ink cartridges have direct contact with, are bent or broken. Click here for details: https://www.inkjet411.com/?page_id=4675
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. Return cartridges to refill lab if any of these conditions are present. Refer to photos here: https://www.inkjet411.com/?page_id=4675
If you have recently updated your printer’s software/firmware and continue to experience a cartridge lock-out, we recommend you return your cartridges to the retailer for smart chip evaluation. You will need to bring in ALL refilled cartridges to ensure each has a compatible chip version installed.
How to Disable HP Auto Updates:
To help prevent future cartridge lock-outs it is suggested to disable HP Updates as they appear (i.e. 1 or 2-week time-based message).
Step 1. When the HP Update prompt is displayed, select Settings (if shown).
Step 2. Select ‘Never’ under Notification software update frequency.
Step 3. If your computer continues to display the HP Update prompt, select Cancel.
NOTE 1: The HP 950/951 ink-series printers use a display panel and require that the Web Services function be enabled for automatic updates to work. To change the automatic update settings you will need to follow the below prompts:
- Open Web Services (open internet web browser and type in the printer’s IP address, i.e. 192.168.x.xx for example)
- Open the Settings screen
- Select Printer Update
- Select Auto Update
Select the On or Off option
NOTE 2: With respect to disabling HP Auto Update printer firmware on Win 10 platforms, unfortunately there is no such button or feature for Win10 operating systems. Microsoft systems removed the options that were there in the prior OS versions to select and deny individual updates. They are now automatically imposed on all who use Win10 Home platforms.
You can follow the instructions in the following link to disable Updates, but not to select individual ones: How to Uninstall and Block Updates and Drivers on Windows 10 (via HOWTOGEEK): https://www.howtogeek.com/223864/how-to-uninstall-and-block-updates-and-drivers-on-windows-10/
TECHNICAL NOTE: The built-in PRINTHEAD will eventually fail over time with usage and age (may or may not be replaceable depending on printer model – refer to User Manual).
