Overriding Used Cartridge Message

[hconn]

My printer recently said it needed a replacement printhead which was sourced and installed (a brand new printhead). However, when I went to put the cartridges back in the printer that I had previously been using, it said I needed to install new cartridges. The cartridges are about 90% and since a new set are £125, I refuse to buy new ones until these are empty. I tried to reset the printer to accommodate this issue but I still get the same message. Is there anyway to override this message and continue to use the cartridges I already have? Cartridge protection was already turned off on the printer before so that doesn't work.

With the new printhead, you should receive 4 new setup ink cartridges that need to be used for a new printhead initialization.

You can save your old used cartridges, they will work later after the ones new you got with the new printhead are emptied.

I didn't receive any setup cartridges with the new printhead and the company are currently out of office due to Covid-19 and so are unable to send me any out, hence my taking to the forums.

Does your printer on the screen ask for SETUP cartridges?

[hconn]

It says 'New, unused cartridges must be used for startup'

Older models have a message to use SETUP ink cartridges, maybe HP changed the message on newer printers.

If you want to take a look in this YT video how it's done on the older printers ( not your model, but the steps should be the same).

I think it is a different message as I have followed those instructions (in fact I already had trade supplies enabled) and it still didn't work

If you want to risk trying there is a resets menu in the hidden menu. The first level is a partial reset. If partial reset isn't helpful full reset and finally OOB ( out of box) reset maybe that will help.

I have tried both a full and partial reset and the same 'New, unused cartridges must be used for startup' message still appears
