Cutting problem that nobody seems to have....

[Brilliant Colorworks]

I have a sp540v. Been a great machine. Recent problems and attempted remedies:

1. a few black jets just quit firing right at one edge of the printhead. Cleaned several times, soaked, manually expressed cleaning fluid from syringe from top of manifold. (i chalked it up as "I need a new head" and I'm living with it.) I compensated by dialing up the print adjustment (user menu)

2. Started having intermittent pinch roller errors/ sheet setup error. Have clean the interuptor sensor on the tool carriage several times. Based on process of elimination, I have identified 2 pinch roller assemblies that are causing this problem. No issues when those are not used. I can live with that.

3. What I CANNOT live with is this, I make a lot of install patterns with the plotter/pen. Been great for years, no issues. Cutting vinyl, BIG STUFF, LONG STUFF, been great for years, no issues. NOW all of the sudden, if I have a file that say the start point and the end point should measure 100", it only measures 98". Have replaced ALL the pinch roller wheels. Environmental matched, adjusted the "hold down bar", it was starting to become easier to push down, so the media is gripping fine. I've tried adjusting the calibration both in the user menu and the service menu to no avail. I tried different medias, tried a different file. No matter what the overall length of whatever I am cutting comes up about 2" short (story of my life). The surprising thing is that all cut/drawn objects have closed paths. No gaps in any letters. Am I missing something? Would a bad cable cause this? I do need to replace some but I would think that a cable would cause this sort of problem. I am challenging anyone to help me solve this. It seems after days of reading/searching all over forums that nobody has had this problem. I do most all service work myself. Now that I have a service manual my next adventure is replacing the printhead.

Thanks in advance.

Ya
when the material hits the ground hard it pushes the material or doesn't push the material . so it hits the ground and cannot move the material forward as much as it should. ends up short, the more it happens the farther off it gets. One thing we hated about cutting with the roland we had to baby sit anything longer than 32" cause it could hit the ground.
Also try slowing down the cut speed.
Hope this helps

Thanks for the reply. I've had no issues forever. I feel there is something obvious that I'm missing or I'm not understanding how to properly adjust. If so far out of whack all of the sudden, I don't know what would have happened.

Major Problem SOLVED!

3rd problem solved. Embarrassed to say but at least I was able to figure it out.

Solution: I recently 2 weeks ago changed operating systems from XP to Win7. I have my Versaworks A Queue setup for Printing Only and my Queue B setup for cutting only ( i only use one specific profile for every cut-only job). When I made the change I had to reinstall Versaworks. I forgot to change the factory default profile from "Generic Vinyl I" back to my usual profile MCVP. The "Generic" profile had a feed calibration setting of 0%. The MCVP profile has a calibration of (-.05%). Changed to this MCVP profile and all is back to measuring properly! What a relief. I KNEW it was something like this. Weird thing is since the OS change, the past several jobs that I cut were not long enough to expose this issue. I guess it was just a coincidence that the pinch roller problem started happening at the same time. Yay Me!

I'm going to replace my ribbon cables over the next few weeks to see if the other issues clear up.
You may all go back to happily printing!
