How do I change setting on my Office Jet Pro 6978 to accept a non HP Ink Cartridge

[JimKraus]

I have an office Jet Pro 6978 and I purchased a "Premium Ink Cartridge" fro LxTek. Upon installation the printer has blocked the printer firmware because its cartridge contains a non HP Chip.   My understanding is that I can change a setting so that the printer does in fact work with this cartridge.  How do I do that?

Hi @JimKraus,

Welcome to the HP Support Community. 

I'd like to help!

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

Step 1: Update printer firmware

Let's start off by updating the printer firmware. If your printer is connected wirelessly, make sure to temporarily connect the device with USB and then follow the link to install the latest firmware update on your printer from our HP support website, using this link. Alternatively, you can also try to update the printer firmware directly from the printer control panel. Once done, restart the computer.

For more details on how to update, please use this link: HP Printers - Updating or Upgrading Printer 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, and 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 the warm-up period finishes and the printer is idle.

The next thing, I would suggest here is to follow the steps in this support document.

Hope this helps! Keep me posted for further assistance.

Thank you.  I will be following your suggested fix.  But first I want to provide you with some info.  I contacted the 

Amazon vendor who provided the cartridges that did not work.  They told me that HP changed their software and as a result, they needed to upgrade their cartridges.  They sent me 2 replacement cartridges - no charge.
