Motor Speed Adjustment
If "Sub-scan Magnification Adjustment Procedure" does not solve the sub-scan
magnification error, the setting of the motor speed adjustment may be out of adjustable
range. Check the following three points.
1. An error ("1") occurs in the SP1-803-004.
[Setting values of the following SPs + input value with SP1-803-001] > motor speed
adjustable range
e.g.) 3.5 (SP1-801-002) + 1 (SP1-803-001 to -003) = 4.5
In this case, "4.5" is over the maximum adjustable value ("4") of the SP1-801-002. As a
result, the result of the motor speed adjustment issues "1" (error).
 Adjust the settings of the SP1-830-001 to -003 so that the total value (motor speed
setting value + input value) is within the adjustable range for each motor described
below.
