Calibration (Feeding Direction) - Roland VersaCAMM VP-540 Service Notes

4-11 CALIBRATION (FEEDING DIRECTION) (Referential Time : 20 min.)
This adjustment is for calibrating the feed amount of media. It allows the media to be fed proper amount by
calibrating the variation in Grit Roller diameter. Calibration is made based on the value in feeding media
[PET-G].
Without proper calibration, it may cause misalignment in the feed amount of media, and it results in the
problems such as white banding, banding of overlap or the dimension error of print result compared to the
original data.
Take-up Unit must not be used during this adjustment.
Turn on the Sub Power SW while pressing [
1
[ ] keys to enter the Service Mode.
Setup the PET-G on the machine.
Select [PRINT MENU]> [CALIB.DEFAULT]> [TEST

PRINT], and press [ENTER] key.
Test Pattern will be printed.
Test print requires 510mm or more of the
media setup width.

to calculate the calibration amount with the formula
shown at step 4.
Test pattern is always printed with offset
0.00%. Even if a correction is made in the
[SETTING] menu, the test pattern is not
changed.
