AR-405 * Note for assembling the copy lamp unit Move the copy lamp unit to the paper exit side, and fix the copy lamp unit wiht the harness guide so that the distance between the copy lamp harness and the lower frame is about 25 ~ 30 mm with the copy lamp harness extended. Shift the copy lamp unit to the paper exit side, and fix it with the harness guide so that the distance from the lower frame is about 24 ± 2mm with the copy lamp harness extended. After fixing, manually shift the copy lamp unit a few times to check that it moves smoothly. If the copy lamp harness is loosely fixed, the copy lamp unit may jump up when reading, resulting in abnormal reading. AR-2XX/3XX series
