PIXMA MX722 Thick Black Line on scanned document

tfeichtel — Fri, 01 Dec 2023 14:00:12 GMT

I have a Canon PIXMA MX722. When scanning a document through the ADF or directly from the glass plate the document has a 1 inch thick vertical black line about 1 inch from the hand margin. When scanning a PDF it's on the right side but JPEG is on the left. I have cleaned the glass based on suggestions from other posts. I'm not sure what else to try to resolve this issue. Any help is greatly appreciated!

Hi Spooky4721,

The lines on copies that you are experiencing is a result of the scan glass being dirty or scratched. The scan glass that the printer uses when scanning from the ADF is located to the left of the larger glass area (platen) when you open the cover. It is the smaller glass strip on the left hand side of the unit.

Spray some glass cleaner on a paper towel and then clean the smaller glass area. Once cleaned, try scanning from the ADF again.

I have had this problem for a number of months now on my Canon MG6450.

I don't have an autofeed so everything is done on the platten.

It happens when scanning or copying and appears as a broad bar on the left ie originating from the back of the platten side.

On copies it seems to be just black but on scans you can enlarge it and see it's more complex - see pic which represents the 1 inch width.

This does not seem to be a dirt/cleaning problem.

Any suggestions?

Hello, the suggestion to clean the glass did not work at all. There is a 1/2" vertical bar on the page after you make a copy or scan. I changed the head alignment and the bar moved to right side to the left side. What is causing this and how can I fix it?

The thick black bar that we are experiencing has NOTHING to do with the glass being dirty. Based on the picture provided that should have been obvious.

Was this issue every resolved? I have the exact same problem with my MG3022. Only happens when scanning a document on the platten. There is no feeder on this model so it can't be the ABF.

Same problem on my MG6620. 1/2 inch wide down the left margin.

I have a Canon pixma TS3355 All in one Wireless Injet printer when I scan or copy there is a wide margin on the right side of the document. I too have cleaned the glass as advised, installed and unistalled the printer but nothing works. I have advised canon support but to date had no answer other than an acknowledgemnt of my query.

This thick black line has NOTHING to do with dirty glass. A section of the glass scanning rod is burned out and is not repairable.

I have the same issue with a 2-month-old TR8520. I tried scanning for the first time a few days ago and have been looking for a solution. The bar is there when scanning on the platen, the adf, and when copying. Is there really no fix for this problem? I'm very disappointed that it's not working.
