My one + year old Epson R260 printer acted up last week. I replaced 4 color ink cartridges about two months back and i did that as i was in the middle of prints. The R260 printed normally with these new (Epson genuine) cartridges at that time however, after two months of sitting idle, when I powered it up, I got "unknown cartridge" message for one of them. While trying to fiddle and figure out, I re-inserted a few of the cartridges only to end up with 3 of them showing as "unknown".
After having no luck with Epson tech support, I took apart the printer to make sure all the ribbon cables from the head assembly to the main board are snug.
Does any body know how this cartridge sensing work on Epsons / R260's. Is it possible to some how to fool the printer, perhaps by shorting some contacts on the cartridge itself to make it recognize them as good. Actually I dont even know if the problem is with the cartridges. They are new and have gone only through 6 / 7 printouts at 5"x7".
