Z6100 not recognizing maitenace cartridge


New Member
I have a HP Z6100, and all of a sudden it wouldn't load paper, then it won't let me replace the maintenance cartridge. My tech told me pull out all the consumables, inks, print heads, maintenance cartridge/ media. Then turn machine off, Then clean encoder strip thoroughly, then re-install all consumables when prompted.

I've done it all, when done cleaning, it lets me replace the inks, but then it says to replace maintenance cartridge, but when I re-install the cartridge, it just asks me to install the cartridge, and I can't exit out of the menu. It's a vicious cycle.

Of course we're swamped, and my tech is on vacation.

Any ideas?!!???
