Do this procedure to confirm that the paper is centered in the paper path.
- Make sure that the I/F cable of the unit is connected to the upstream device.
 - Disconnect the unit to the left of the unit to be tested.
 - Execute a run by feeding paper from Tray 2 of the host machine.
 - When each sheet exits, check the position of the paper on the scale to see if the paper is centered.
- Read the rear scale for DLT-size paper
 - Read the front scale for A3-size paper.
 - The scale lines are spaced 2 mm apart.
 
 The paper must not deviate more than ±2 mm on the scale.
[A]
Leading/trailing edges centered. No adjustment necessary.
[B]
Leading/trailing edges offset to the rear by more than 2 mm. Adjustment required.
[C]
Leading/trailing edges offset to the front by more than 2 mm. Adjustment required.
If the edge of the paper is on the scale at the center [A], no adjustment is required.
-or-
If the edge of the paper is ±2 mm off the center line on the scale, adjustment is required. Do the procedure in the next section.
