  2. Click the link for your HP printer model in the following table and run the downloaded firmware update file from your Internet browser.
  3. Look in the HP Printer Update window to see if your printer serial number displays.If the serial number is listed, select the printer serial number, and then click Update.
    1. If the serial number is listed but status is not applicable (grayed out), the firmware does not need to be updated. Click Cancel.
    2. If the serial number is not listed and your printer is using a network connection, connect a USB cable, wait 20 seconds, and then click Refresh.
  4. When the update is finished, click OK.

NOTE 1: HP printer firmware update is not available or required for the HP Officejet Pro 8100, 8600 and 8600 Plus, OfficeJet Pro 276dw & OfficeJet Pro 251dw printer models which use HP 950/951 cartridges. If these printers display a cartridge error condition, please refer to our general support page for suggested resolutions: Click Here

NOTE 2: If you experience difficulties with downloading the HP printer firmware update file, we suggest you close all other network/web processes and attempt to download the file again. In addition, the presence of too many tracking cookies running on your computer or your computer’s storage space allocation may be too low (the firmware download file is ~24MB in size). You may also need to ‘clear cookies’ & ‘clear browsing history/temporary internet files’ under you Internet “Settings” tab….this usually makes things run much faster overall. Once these suggested items have been completed, close your browser, relaunch and try to download again.

NOTE 3: We suggest you Disable HP Auto Updates, see below for instructions.

Additional Resolution Steps:

If you have recently updated your printer’s software/printer firmware and continue to observe cartridge error messages, we recommend you return your cartridges to the retailer for smart chip evaluation.*  Please be aware that printer error/message can jump from color to color; all refilled cartridges may be suspect. You will need to bring in ALL refilled cartridges to ensure each has a compatible chip version installed.



How to Disable HP Auto Updates

0_hp-chip-lockout_sept-2016Some of the newer HP printers may receive a firmware update (either installed automatically or manually installed by customer) which may lock-out the cartridge’s smart chip and prevent printing.  It is suggested that you disable either the ‘Auto Update‘, ‘Update Printer‘ or ‘HP Update‘ feature moving forward to help prevent future chip lock-outs when using refilled ink cartridges. Win 10 Users, please refer to NOTE 4 below.

HP can use at least two different methods in attempt to get firmware updates pushed out to inkjet printers.

1. The first affects all printers and uses a piece of software that is installed during the printer setup called HP Update. This HP Update software will periodically check on the web to see if any firmware, drivers, or other software updates are available for the HP products installed or connected to the computer. Once an update is found it will prompt the user that the update is available and ask them if they want to download and install it; “Yes/Continue or No/Cancel”. The prompt does not provide the user any information about the update or what it wants to install. If the user selects “Yes/Continue” then it will grab all the available updates and begin installing them onto the computer and attached printer hardware (i.e. via USB or WiFi). If they select “No/Cancel” the prompt is hidden for a short period of time but the prompt will eventually return.

HP-Updates_5_sm2. The second is an Auto Update or Update Printer feature that appears to only be installed onto printers with display panels with web services enabled and is turned on by default on select new printer model series. If this feature is enabled then the printer can, without any notice, download updates automatically and install them.




All Printers – HP Update Software

To prevent the software from updating the firmware on the printer the user must continue to select “No/Cancel” when prompted or they must remove/uninstall the HP Update software from their computer (i.e. refer to your computer’s program removal instructions). The HP Update software is not part of the print driver so functionality will not be affected if you remove.

Step 1. At computer, either go to Programs and locate the HP Update software in the HP folder and open, or when the HP Update prompt is displayed, select Settings.


Step 2. Select ‘Never’ under Notification software update frequency.


Step 3. If your computer continues to display the HP Update prompt, select Cancel.



NOTE 4: With respect to disabling HP Auto-Update on Win 10 platforms, unfortunately there is no such button or feature for Win 10 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 link to disable ALL Win 10 Updates, but not to select individual updates: How to Uninstall and Block Updates and Drivers on Windows 10 (via HOWTOGEEK):



Web Services Enabled Printers – Disabling Automatic HP Updates

HP 950-951, 970/971 & 980/981 Ink-Series Printers

These 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 it is suggested to perform the following steps:

  • 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 (Off to disable)


All Other HP Officejet & Officejet Pro Ink-Series Printers

This procedure applies to printers with and without a display. The printers without a display panel can only be updated through the HP Update software. The printers with a display panel, with Web Services enabled, may come with Automatic updates already enabled on the printer by default (varies by model). To change these automatic update settings on printers with display units it is suggested to perform the following steps:

  • Open the Setup (or Settings) screen
  • Select Printer Maintenance
  • Select Update Printer
    • Select the On or Off option (Off to disable)



Initial report from ACTIONABLE INTELLIGENCE on this subject (Sept. 20, 2016) – HP Inkjet Printer Firmware Update Disables Some Third Party Inkjet Cartridges



*Typically when a cartridge lock-out occurs the error message “Cartridge Error: cartridge missing or damaged”, or similar language will be displayed when using refilled ink cartridges that have a replacement chip installed.  Providing the printer firmware has been updated, it is suggested you ensure all four (4) ink cartridges have the latest replacement smart chip installed (verify with your ink refiller). If cartridge detection problem continue to persist, it is possible the internal PRINTHEAD may have dirty electrical contacts or internally bent or broken pins (click here for more information).
