Hey Chase38,
All of the above ideas are relevant, but don't forget to update the printer firmware (which improves crop mark and feed functions).
Also, it's important to verify the problem is truly the printer hardware and not something else, such as the material itself. The following information will help you isolate the problem to its source.
Crop mark detection and/or cutting inaccuracy could be the result of the sensor being out of calibration, it could be a lighting issue in the room, it could even be a light reflection/glare issue with the lamination.
Try the following:
1) Print a job with crop marks and when it's finished printing, do NOT remove the media from the printer.
2) Use the UP arrow to reverse the media until the lead edge crop marks are positioned properly over the cutter protection strip.
3) Set the "base" point on the printer so when the printer scans for the marks, it does not advance the media.
4) Setup the software for "cut only" and send the job to the printer so it can detect the crop marks.
If the marks are not detected, or the cutting is offset of the print, the printer will require inspection and calibration.
However, if the job cuts spot on, then the problem is likely related to the laminate, or the way you're manually reloading the media after it's laminated.
Try reloading the media, being very careful that you're positioning the leading edge crop marks properly over the protection strip. Once you're 100% sure the material is loaded properly, try adjusting the lighting in the room to reduce reflection/glare that the sensor is likely detecting (even move the printer to another part of the room, if you have space to do so).
Try cutting again.
Ultimately if the problem continues, please call your Roland dealer and explain the details of the failure. They'll take over and resolve your issue.
Take care,
