Printer won't recognize almost new Maintenance Tank
Epson 7800 suddenly has message "No Maintenance Tank Installed," even though the Maintenance Tank is almost new, and was recognized up until then. The same thing happened a few months ago. I used a resetter on the Maintenance Tank chip without response. I thought maybe the chip was somehow corrupt, so installed a brand new Maintenance Tank. Still didn't recognize it. Then the issue resolved itself without me doing anything. Since I didn't really do anything to fix it the first time, I'm stumped as to what to do now. Anyone ever run into this before?
Try to change the firmware of the printer.
