Canon ir 2200 help
For problems with the hard disk on the Canon ImageRunner (my model is 2220n):
Step 1: Unplug the unit (leaving power switch on), and then plug back in while holding down the 1 and 9 keys
Step 2: Wait. The hard disk will reformat - you should see at first a flashing white block in the upper right hand corner, then you will see white blocks building rows on the screen left to right with the screen eventually filling entirely. This may take an hour or more.
Step 3: After reformatting, your screen should say "Download Mode" at the bottom. Now just turn the machine off, unplug it for a few seconds, plug it back in, and then turn it on (you must switch power toggle off and then on - not sure if unplugging is necessary but it worked for me).
This site is great and has saved us at least $1,000 on copier repair this year - repairs that really didn't require a tech at all.
