Keep the upper registration roller position adjustment top [1] in position
when replacing the upper registration roller.
The position of the upper registration roller is factory-adjusted. Changing
its position could result in troubles, such as skewing during document
scanning.
Note the reading on the scale [2] observed before replacing the upper
registration roller position adjustment top, so the new upper registration
roller will be set exactly at the same position as the roller just replaced.
Remove the rear cover with the two claws released.
