I have a GX4020 that's a little over a year old and has seen very light home usage. The scanner ADF has been used probably less than 20 times. Now when ever I try to use the ADF, it jams on the first page. Even with a single page it will jam, let alone multiple sheets.
The feeder grabs the top sheet and pulls it in about 2cm, then the paper stops moving while I can still hear the mechanism trying to pull it through. After a few seconds it beeps and gives an error. Clearing the error and jam then trying to scan again results in the same problem. I am only able to scan manually as multiple attempts using the ADF result in failure. I'd guess less than 1 in 10 attempts will actually succeed.
I've cleaned the rollers and have made sure there is nothing else stuck in the ADF. It still jams.
I reported this to Canon support and was told it was referred to another team to process and approve for exchange. However that was over 2 weeks ago (Feb 11) with no further updates. I suspect because my printer is out of the 1 year warranty period (bought Nov 2023, problems reported Jan 2025) they are not going to do anything.
Anyone have any suggestions on how to get this working? I purchased this printer because it was supposed to be reliable. It looks like it's time to abandon it and Canon for a different brand.
