This printer is 10 yrs old. Worked fine until this morning. Turned it "on", got "carriage jam" error message. Viewed HP video for the machine, applied all the possible fixes: clear any paper jams, clean encoder strip, power resets, re-seat cartridges; still have the same error message.
When i watch the carriage in action, it does fully slide from right to left a couple of times, like it is working fine; then it sits at the extreme right side for a second, moves forward 6 inches and then slams back to the extreme right position; error message appears.
Any suggestion are appreciated. Thanks!
