SHARP SF-A56
Service Manual

�

If the mode is to be set in combination with other options, use the table shown below to add up the total of the setting values for all the peripheral devices to be set, and set that total value. For example, if the SF-A56 and sorter are to be set, the total setting value is 1 + 10 = 11. Operate the keys as follows:

The leading edge position can be adjusted within a range of 8 mm (8 steps) on the stopper side and 7 mm (7 steps) on the glass side in 1 mm increments. Adjustment can be done separately for the one-sided, two-sided, and thin paper modes.
