COPY ADJUSTMENT

Main Scan Dot Position Correction

NOTE: Before adjusting the scanner, adjust the printer registration.
1. Enter the Copy SP mode and open SP4-932.
2. Check that each value corresponds to the factory-set value.
3. Touch the COPY Window key and copy the C-4 chart in the full-color photo
mode.
NOTE: Be sure to copy in the photo mode. This is because color displacement
cannot be checked properly in text mode.
4. Check the yellow and cyan vertical lines. (Use a Magnification Scope to do
this.) If they exactly overwrite the black line at the edges of the copy, exit the
SP mode to end the adjustment. If the yellow and cyan lines significantly
extend beyond the black line, proceed to the next step.
5. Press the SP Mode to return to the SP mode. Adjust the SP settings until the
output is acceptable.
