4-9 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 a problem of the position error of the cut line
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.
The Pre-heater, Print Heater and Dryer must be off during this adjustment.
When it needs to be adjusted for a user media, use the media instead of SV-G-1270G. However, in this
case, the adjustment is to be optimized for the particular 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-G-1270G is used for this adjustment.
