HP LaserJet 4
HP OfficeJet 7000 no cartridges recognised
I have this Officejet 7000 wide format printer just over 1 year old so out of warranty. It was working fine then all 4 cartridge lights started flashing, the HP on-screen toolbox says no cartridges recognised.
So far I've removed the print head & cleaned the contacts with IPA then re-seated it. I've done a power re-set. I've replaced all 4 cartridges with new HP originals.
If I go to the HP on-line diagnostic page & enter the fault, cartridge lights flashing, netrwork light steady, power light steady, it tells me this condition can not exist!!!
I'm out of ideas & would be grateful for any help you can give.
