pinchroll errors on Roland SP-540V

[Mantaworld]

Hi All-I am having this same issue with my SP540V. I've ordered the carriage cable, but my vendor will not allow one of their techs to come out and install it. Does anyone know of resources online with good instructions for DIY?
I appreciate any help/advise.

Thank you! I'm going to give it a shot and if that doesn't fix it I will be buying a new printer/plotter

Hi Carrie,

If you can get your hands on the service manual, it does give you instructions on how to do this. I have had to change them on our SP-300V's a few times over the years and the manual is very helpful. If you are unable to get your hands on it, I would recommend taking the top covers all off the machine and run the new cable with the old one and disconnect and connect as you go, so it all stays the same way.

Definitely the carriage cable. I had the same issues on mine and had to replace it and worked fine after. Definitely get a manual to see where the cable goes. It's not really hard just a little tricky in spots to get in.

Deeper Detail

Just some deeper detail here...

When the printer is reading the pinch wheels, it uses the pinch wheel sensor which is on the back of the cut carriage. This is transmitted to the servo board via the cut carriage cable.

The sensor that reads the linear encoder strip is on the print carriage. The linear encoder strip is only used by the machine to know where the print carriage is along the linear rail.

You can have a hole in your linear encoder strip, and it will still find the pinch wheels. It just wont print where the hole is... (Yes I've seen this)

I will replace a cut carriage cable in an SP-series machine at least once every few weeks. It's a known issue, and there is a field service note from Roland.

Don't delay in resolving this issue.

BTW... Roland revised the way the cut carriage cable works on the VP and newer machines.

Check that the data cable to the pinch wheel sensor is connected! You will have to have a mirror to see behind the cut carriage. Easy enough to plug back in if you have tiny hands :/

Pop one of these bad boys in there and it should fix the issue. It's a pretty common isI

Completely agree. I've run three SP-300V's for close to 15 years on a narrow width media so lots of scan movement and only get about 12 months out of a ribbon. Interesting thing we've noticed is when the cable's close to failing one of the cable strands gets a magenta stain close to where the cable comes up out of the main board cabinet so we always know about 2 - 3 months before the cable fails.

I had a crash, my right media clamp came loose. I was getting the left position error, I replaced the pinch roller but was still having a pinchroll error invalid left position or invalid right position so I replaced the carriage cable.

Now I can print and cut but when I try to sheet cut, it says to remove the media clamps even though they are not present, any thoughts on this?

Just ignore it and press enter, it is just a warning, the printer can't actually tell if they are installed or not
