let's say, you refilled your cartridge and all of a sudden, your printer doesn't want to print anymore or the pages come out absolutely white... It's time to reset the printer with the following steps (thanks to http://canonmp495error5200.blogspot.de/2012/06/question-how-to-resolve-critical-error.html):
- Unplug the printer from power and wait 5 sec then plug it back in.
- Press "Stop/Reset" button for 2 sec and hold it.
- Now press and hold the "Power" button also with "Stop/Reset" for 5 sec.
- Release only "Stop/Reset" and wait for 2 sec (still holding "Power" button)
- Now press and release "Stop/Reset" 5 times.
- After 5 sec release "Power" button also (no LCD only power light is working).
- Wait for a minute (counting starts after step 6).
- Now power off the printer by pressing "Power" button.
- After 30 Seconds press "Power" button again. You are ready for printing NOW :-)
Good luck.
