Also, autocutting ahead of the perforated line may cause problems when feeding paper. Therefore, autocutting must be performed 0.5 mm to 1 mm {0.02 to 0.039"} behind the perforated line.  Black marks must position away at least 0.5 mm {0.02"} from the perforated line.  The perforated lines on both sides of the paper edge must be left uncut.  Make sure to keep the same position of the black marks to the perforated lines (position that can be detected by black mark sensor) when inserting the paper from either side in order to use the paper inserting from reverse direction. 5 207
