MF644CDW Scanning paper feeder crumpling source paper

[noorezk]

When the paper feeder pulls in the paper to scan, it does not pull the paper in properly..   instead of going in flat and smoothly, the paper slightly lifts on the sides, folding the paper slightly upward and towards the centre... the result is a skewed scan result image and the original copy having crumpled/torn sides (the impression of the torn sides is similar to how gears would crumple the side of a paper if it got caught in them).

Greetings,

There might very well be something going on with your ADF.  It should be opened and inspected.

In addition, setting the paper guides too "tight' can impede or skew proper feeding.

Thanks,  sorry but what is ADF?

The paper guides are opened up fully and they don't appear to be hugging the paper too tightly at all.

Hi Noorezk,

Welcome to The Canon Forums!

Please ensure the proper paper is being used when scanning,

Try cleaning the automatic document feeder used for scanning. Cleaning the Feeder instructions

1.Turn off the machine and unplug it from the power outlet.

Turning the printer OFF erases any queued print data. Data such as documents received and held in memory, documents waiting to be sent, and reports that are automatically printed after sending or receiving faxes are not deleted.

 2. Open the original supply tray.

 3. Open the feeder cover.
 
 4. Wipe the rollers in the feeder.
Wipe the rollers with a cloth that has been moistened with water and wrung out. Then wipe with a dry cloth.
If the rollers and surrounding areas are very dirty, clean them out. To do this, wet a cloth with water and wring it out well, then wipe the dirty areas. Afterwards, wipe the areas with a soft and dry cloth.

 5. Close the feeder cover and original supply tray.

 6. Open the feeder.

 7. Wipe the document feed scanning area.
