Check manual or tech support. Maybe youtube has video. check your automatic document feeder for blockage.

Automatic Print Head alignment failed
Possible causes are as follows:
A4 or Letter-sized paper is not loaded on the Auto Sheet Feeder.
Press the RESUME/CANCEL button on the printer to clear the error, then load one sheet of A4 or Letter-sized paper in the Auto Sheet Feeder.
Automatic print head alignment cannot be performed using paper from the Cassette. For automatic print head alignment, always load paper in the Auto Sheet Feeder.

Print Head nozzles are clogged.
Press the RESUME/CANCEL button on the printer to clear the error, and then print out the nozzle check pattern to examine the print head condition.

For information on how to print a nozzle check pattern, see "Printing the Nozzle Check Pattern."

The Paper Output Slot has been exposed to a strong light source preventing correct Print Head alignment.
Press the RESUME/CANCEL button to clear the error and move the printer to a darker location.
After carrying out the above measures, if the problem continues after aligning the Print Head again, press the RESUME/CANCEL button to clear the error, and then perform manual print head alignment. For details on manual print head alignment, see "Manual Print Head Alignment."

Printing envelopes on Canon MX892: Remove paper from rear tray. Adjust gray width handlers to the size of your envelope. Insert a blank envelope in the rear feeder, with flap oriented on the back left side.

Did you download and install the MP Toolbox (shown under the Software heading) from this link? This is the software program that allows the computer to use the scanner.

There is a paper sensor just under the rolers in the lifting tray. Clean the area thoroughly with a damp cloth. Keep some sheets and try ]count only'. If it works then the sensor is okay, then you can try your scanning. If it is not sensing paper, check the sensor or connections to the sensor.

You omitted some details which might help diagnose the problem. For example, are you using the document feeder or the flatbed? Anyway, I'll take a guess here.

Check your paper size setting and make sure it matches the sheet you are scanning. (Letter, A4, Legal, etc.)

If this is not it, then try scanning from both flatbed and feeder and see if results vary. Note that when you use the feeder, scanning is done in a smaller window to the left of the flatbed, so make sure that is clean.

Open the cover over the scanning area and check the narrow strip of glass to the left of the platen glass. See if there is any foreign material there (dirt, whiteout, etc) and clean it gently with a damp cloth. You may find a piece of clear plastic covering that area. It's there to keep the glass from getting scratched. If the plastic is heavily scratched at that point, it can cause the line you're seeing. Removing the plastic will clean up the scans.
