HP M252n not printing black

[cloggydog]

My HP 252n doesn't print black at all, despite registering the black cartridge (and showing it at c90% full). Have also tried a brand new black cartridge, same problem. 

The 3 colours all printed fine, just not black.

Any ideas, please?

Thanks, but I have run through all those steps in the document at least twice, to no avail.

As you say, it sounds like a hardware issue affecting the contacts between the printer and the black cartidge. The colour ones all print fine.

Since you've tried two new cartridges too, this looks  like an issue with the Printer.
