these cartridges are not intended to be used in this printer

[Nick371]

Product: HP Office Jet Pro 6978 All-In-One Printer

Operating System: Microsoft Windows 10 (64-Bit)

I've just bought the original cartridges from Challenger store and replaced with the empty ones and then suddenly it displays the problem that these cartridges are not intended to be used in this printer, the device software is up to date. 

I just follow the instructions to getting replacement from HP also no use.
HP customer support is also not available online.
HP Smart App is also of no use as it says "Printer Status Unknown"
HP used to be a reliable company but lately I've been disappointed with their product.

Is this because of printer too old?
