How to Fix “Could Not Perform Correction” Issue on Canon Printers

Solution: load regular or recycled A4 or letter-sized paper into the paper drawer.

Solution: put the adjustment image on the platen glass with the print side face down and the black line toward the back side of the machine (as shown in the following picture).

III) Paper jam during the correction

Solution: remove the jammed paper, and perform correction again (as shown in the following picture: 1-Feeder, 2- Interior, 3- Paper drawer, 4- Output area).
