Crop Mark Sensor Adjustment (Referential Time: 10 Min.) - Roland VersaCAMM VP-540 Service Notes

4-8 CROP MARK SENSOR ADJUSTMENT (Referential Time : 10min.)
This adjustment is for adjusting the sensitivity of the Crop Mark Sensor. If not adjusted, the crop marks cannot
be read correctly and it results in an error of cut position to the print. This adjustment is required under following
cases.
- Crop Mark Sensor or Tool Carriage Board is replaced or adjusted.
- The VR for adjusting the voltage is unexpectedly moved.
- The distance between Crop Mark Sensor and the bed surface is changed.
When it needs to be adjusted for a particular media, use the media instead of SV-GG. However, in this case, the adjustment
is to be optimized for the media and it may affect the crop mark detection on other media. The result of the crop mark
recognition on Roland media is not assured, when any media other than SV-GG is used for this adjustment.
The Print Heater and Dryer must be off during this adjustment.
