HP OfficeJet Pro 8615 printer not recognising any ink cartridges.
I have used my printer for more than 4 years without a problem, always with HP-branded ink cartridges.
This week I used a replacement "compatible" cartridge for the first time. Two days later my printer doesn't think any cartridges are installed (including the three remaining HP-branded ones).
I have tried a "semi-reset" which takes me through the initialisation procedure every time the printer is powered up (after various lengths of power-down time), but it always stalls when I have to "insert the cartridges that came with the printer", obviously not happy with the cartridges I am putting in (even my old empty HP-branded colour cartridge that I retrieved from the bin).
I am now aware that these printers (and cartridges?) keep track of how often they are used in combination and HP doesn't like the same cartridges being used.
Basically I want to know whether a completely new set of HP-branded cartridges will solve my problem, or whether there is something even extra-special about the catridges that actually come with a printer? I don't want to invest in a new set of HP-branded cartridges if even that is not going to work, but I can't believe a perfectly good printer should become completely unusable because of a single cartridge mistake.
Any advice / confirmation welcome. Thanks.
