TR8520 - black box in prints and scans

[ryaffe]

Hello:

When making a b&w or color copy or scan, an area in the lower left corner prints all black.  This just started happening.  I checked all the ink cartridges and ran some troubleshooting diagnostics, but nothing changed.  Any help would be greatly appreciated.

Thanks,

Hi, 

Since this happens when copying and scanning, there is most likely a issue with the scanning element inside the printer and 

 I recommend to have this issue looked at by our support team. 

Canon does have a chat team that would be happy to assist you with this issue. Please click HERE and in the chat box, ask to speak to a live person. Our chat agents are available Monday-Friday 8:00 am to 8:00 pm ET, excluding holidays.

Hello:

I spoke with a customer support person several days ago.  The recommendation was to use the document feeder instead of the flat panel when copying or scanning, since the "black box" issue does not occur when using the feeder.  So, the answer was to live with the problem and use a work-around.
