4.4.4.1 Points to Note When Replacing the Upper
Registration Roller
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.
