6.3.1 SUB-SCAN MAGNIFICATION ERROR
If a sub-scan magnification error of an image occurs on an output, follow the procedure
below to adjust the sub-scan magnification.
Sub-scan Magnification Adjustment Procedure
1. Adjust the sub-scan magnification for each paper type and print mode with the
following SPs.
Input the same value in these SP settings. Otherwise, color registration errors
occur on outputs and this cannot be recovered by the line position adjustment.
SP1-803-001: Plain paper/ 600 dpi Input
SP1-803-002: Plain paper/ 1200 dpi Input
SP1-803-003: Thick paper Input
2. Turn the main power of the machine off and on.
3. Check if all settings of the following SPs are "0" (success).
SP1-803-004: Plain paper/ 600 dpi Result
SP1-803-005: Plain paper/ 1200 dpi Result
SP1-803-006: Thick paper Result
If one of the settings of SP1-803-004 to 006 is "1" (error), return to step 1 and
then input a value which is closer to "0" compared with the previously input
value.
For example, if "+0.9" is input in the settings of SP1-803-001 to 003 and an
error occurs, input "+0.8" or less with SP1-803-001 to 003.
For example, if "-0.9" is input in the settings of SP1-803-001 to 003 and an
error occurs, input "-0.8" or more with SP1-803-001 to 003.
If an error still remains, refer to "Motor Speed Adjustment".
4. Execute the line position adjustment (rough) with SP2-111-003.
5. Execute the line position adjustment (fine) with SP2-111-001.
