incompatible cartridge message in laserjet M1212NF

[wfillier]

I've had this printer for a number of years. Recently it's started giving me headaches when trying to print. I keep getting a message stating Incompatible Cartridge. However, IT'S THE SAME CARTRIDGE I'VE BEEN USING FOR 2 YEARS!!!! How is this now all of a sudden an issue?

Maybe because I built a new computer and put a fresh install of Windows 10 on it. It won't allow me to install an older version of the driver either, I have to keep using the broken and corrupt "HP Smart" App, which to be honest, is the furthest thing from Smart.

@wfillier,

Welcome to the HP Forums 🙂 I would like to take a moment and thank you for using this forum, it is a great place to find answers. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for First Time Here? Learn How to Post and More. I see from your post that you're getting Incompatible ink cartridge error on your HP LaserJet printer. No worries, I'll be glad to help 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?

Are you using genuine HP Ink cartridges or refilled ink cartridges.

Did you try to update the printer firmware?

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

Let's start off by updating the printer firmware. 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 on your printer from our HP support website. Alternatively you can also try to update the printer firmware directly from the printer control panel.

For more details on how to update, please use this link:  HP LaserJet - Update the firmware

If the issue persists, I would suggest here is to do 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.

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.

Next thing, I would suggest here is to follow the support document for - HP LaserJet Printers - A Supplies Error Code or Message Displays on the Printer Control Panel

Inspect the toner cartridge for damage:

1. Remove the toner cartridge from the product and verify that the sealing tape has been removed.
2. Check the memory chip for damage.
3. Examine the surface of the imaging drum on the bottom of the toner cartridge.
CAUTION: Do not touch the roller (imaging drum) on the bottom of the cartridge.

Fingerprints on the imaging drum can cause print-quality problems.
4. If you see any scratches, fingerprints, or other damage on the imaging drum, replace the toner.

Try cleaning the contacts.

Use a pencil eraser & clean the contacts on top of the toner, tiny green circuit with contacts on it.

Then slowly insert the toner and look on the left hand side, you will see a black plastic piece flip up to meet with the toner, before it meets the toner you will see 2 contacts sticking out of the black plastic piece, use the pencil eraser to also clean it to see if that resolves the issue.

Try the old Toner to see if it is still recognized.

If you have followed the steps suggested and still having the issue, I would suggest this could be a possible hardware failure.

I will share you few details through a private message about the service options dedicated to your product, please watch your inbox for more information.

I hope this helps resolve this issue completely,

Regards,
