Hi @bb119,


Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community! I came across your post and want to assist you. I understand you are getting an error message on your HP Printer. Don't worry we'll work together to find a solution for you.


To provide you with an accurate solution, I'll need a few more details:

Have you recently made any changes on the printer before the issue started?

Have you tried to clean the cartridge contacts?

Have you tried to update the firmware on the printer?

Are you able to make a copy from the printer?


In the meantime, let's try these steps here:


Perform a Hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector.


Remove all the ink cartridges and then try to perform a hard reset on the printer.

With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.

Remove USB cable, if present.

Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer.

Turn on the printer and wait till warm-up period finishes and the printer is idle.

Now insert the ink cartridges and then try to print a test page and check if it works.


Let’s first try and make a “photocopy” to determine whether the issue is with the printer or not. Place a document on the scanner glass and choose “Copy” option. If the printer is making a good copy, then the printer hardware is fine.


If your printer connected wirelessly, make sure to temporary connect the device with USB and then follow the link to install the latest firmware update, using this link:


Please ensure to clean the cartridge contacts once again and check if that helps. For more details, please follow the steps suggested in the support document for - A 'Cartridge Missing,' 'Cartridge Problem,' or 'Incompatible Ink Cartridges' Error Message Displays ...


If nothing works, I would personally suggest this could be a printer hardware. I would recommend you contact our HP phone support for available service related options. If your product is out of warranty, please choose paid options to get the tech support number.


HP Technical Support can be reached by clicking on the following link:

(1) Once the support page opens please select the country in which you're located. Next, enter your HP model number on the right.

(2) Next, choose the 'Contact Support' tab at the top and scroll down to the bottom of the 'HP Support- Contact' page to fill out the form provided with your contact information.

(3) Once completed click the 'Show Options' icon on the bottom right.

(4) Lastly, scroll down to the bottom of the page and select 'Get the phone number.' A case number and phone number will now populate for you.


Hope this helps, for any further queries reply to the post and feel free to join us again.


Feel free to post your query for any other assistance as well,

It's been a pleasure interacting with you and I hope you have a good day ahead.
