FC8600 what a gem

Check you friction rollers. Sounds like the pressure is uneven

 

There is a calibration test you can do where you print out a series of crosshairs and have it cut, then adjust as needed.

The fact that it's off in different directions on the front & back of the sheet is odd. I can't think of anything that would cause that. Does it have issues finding the crop marks on the sheet?

 

i read this post this morning, and i was wondering if what he was describing is just the
friction feed slipping a little when it advances?.
something like bad pinchrollers?

 

Correct me if I'm wrong, but wouldn't that cause the cuts to all be off in the same direction? he described the cuts being off in opposite directions on the front vs. back of the sheet.

 

I love how something can work "fine" for 5 years and all of the sudden something doesn't go quite right and now the plotter's "a pig". It sounds as if the scale is off for some reason.
Is it just this file or are all jobs doing this now?
What media are you printing on? Is the liner slick? Is it heavy? - Magnetic could do this to you.
Check the pinch wheel pressure as mentioned above.- are they the same? are you using all available wheels?
Are the grit wheels clean? Have you checked the pinch wheels? - they're a consumable you know.
Is this laminated media? I've seen laminators with improper tension stretch a print and cause this type of mis-cut.
For print/cut troubleshooting I like to create a simple file of 2" blocks spaced 1/4" apart in a matrix of roughly a square that will fill the width of the media with a contour cut right on the edge of the print. So, on a 54" printer/plotter combo, do like 20 across and 20 deep. Now you can measure your print as it comes off of the printer, then measure after lamination if that's part of the workflow, and then measure the cuts after you cut it. Compare all of these with the file. Many times the printer is off, and we think it's the cutter.
A little more rare, it could be the feed motor is wearing out and not keeping track, but you'd probably be seeing error codes when this is the case.

Good luck

 

the plotter is just a piece of equipment a person has to operate and set up, it doesn't do anything other than what the operator makes happen.

 

You need to apologize to your cutter.

 

Like I said it isn't the plotter it is the operator, now you need to go hug you Graphtec and appolgize for calling it a pig:-{)}
