My year old Canon Pixma TR8520 stopped rpinting and copying, error code 6004. Deleted all drivers, did all the error code instructions which was to turn off and on-nothing worked. Turned in my machine and bought another TR8520. Doing exaclty same. When you copy the paper comes out blank allthough youcan here the printer printing. when i print from PC the ink is on the paper but super light and not discernable. Whats going on- i have reinstalled drivers again- no error code like last TR8520 but really the same issue.
