Won't accept serial number or product number

[thirda]

I've tried and tried to get things set up but it's not working. When I try to add the serial number it tells me to add the product number and then tells me it's invalid and to add a valid number but it's the number both on the computer, on the app and on the printer diagnostics. I bought it second hand so I'm wondering if needs to be reset or if there's something else I need to do.

Use following page to check serial number is it recognized for your printer model

The serial number is 10 digit starting with 2 letters

The serial number is accepted but it needs the product number and the exact product number isn’t there. There’s a similar one but the letter at the end is different and in the title it has “loyal” but otherwise is correct. Have they stopped servicing this printer or something?

Check the product number on the printer itself, it must be on a label, on the back side, or under toner access door.
