VS 640 issues.

Hello everyone.

I have a Roland VS640. I've had it for about 11 years now and it has been a pretty good machine. For a while now, I've been fighting with some faint CMYK lines that print around the 42" mark. Usually they're not very noticeable, but I would like to finally fix the issue. Just recently (yesterday) the printer has begun stopping before a print is complete. Versaworks would say the print job is 80% done, the display on the printer shows "Now Processing", but the carriage will sit over the cap top. If I lightly slap the side, the carriage will make a pass, but then come back and it won't do it again. What could the issues be on this? I've read through posts here saying to clean the encoder strip and also lube the rail bearing. Lubing the bearing...no problem. Where is the encoder strip though? What does it look like and what's the best method for cleaning it?

Any help would be appreciated.

Thank you.

Any photos of the issue?
I'm suspecting a dirty encoder strip at the moment.

It's a clear strip that runs along the back of the main rail that the head travels across. There are very tiny lines printed on it that enable the machine to determine where across the rail the head is so it can drop ink appropriately. If it gets dirty it can get confused as to where the head is and either print in the wrong location or travel back home unexpectedly.

Thank You for this info. My roland XR 640 just did this today.
I'll be cleaning the En oder strip in the morning.

flat cables from main board to carriage board they are three, change them, cables are cheap but job is not to cheap

I'm sorry for the delayed reply. Thank you for the information. I plan on addressing the issue this weekend. I don't have any new pics, but will post some when I have a chance. Thanks again.

OK, thank you for this information. I'm not afraid to work on this printer, as I've done it before. I'll get some cables for it and swap them out. Thanks again.
