K. Carry out the print off center adjustment (1) Adjustments with simulations Since the off-center adjustment has been made at shipping, there is normally no need to adjust. If, however, the center is shifted, carry out the following steps to adjust. 1) Set a test chart (document) on the document table properly. 2) Execute SIM 50-5 (Print off center) by the key operation of the main unit. 3) In SIM 50-5, the display is shown as follows to allow setting of the print off center adjustment value for each paper feed tray.

Repeat this procedure as required. ∗ For details of the adjustment and check procedures, refer to the chapter of adjustments in the Service Manual of the main unit. (2) Mechanical adjustment Since the off-center adjustment has been made at shipping, there is normally no need to adjust. If the center is shifted, however, adjust with the simulation. If the shift is not recovered, perform the following steps to adjust. 1) Pull out the large capacity tray until it stops. 2) Loosen the stopper fixing screw (1 pc.) on the lower right side of the paper feed tray to disable the stopper function.
