Need Help Roland XC540 RIBBON CABLES & SCAN MOTOR ERROR HELP REQUIRED

This information is based on my SP540V, but your's looks very similar.

There are plastic hold downs for the cables. They are held in by tiny plastic pins/rivets. Looks like they came undone causing your issue. You can order those bits from a Roland dealer.
You will also have to set the correct looping of the cables to prevent binding. There should be a specification in the service manual.

 

Nothing should be glued. Only thing I can think of is something got hooked on the cables and pulled them creating extra slack. I know when I replaced the ribbon cables I manually moved the carriage to check for proper "looping" of the cables. I spent about 15 minutes making sure it was right.

Keep us updated and post the solution once you get it figured out.

 

The is always going to be some slack. It's a rolling loop. As RJ pointed out though, it needs to be the correct amount of slack and it takes some time to get it dialed in. If it's been caught on something, you'll need to replace the ribbon cable add well as the plastic guides. Then dial it in properly.

When i do it, i always recommend replacing the cable, the guides and the cut carriage board, but if you replace the board, you'll need to calibrate the crop mark sensor.
The board is probably not necessary, but that way, we've covered all the basesand it has to come out to replace the cables anyway and the board is cheaper than another service visit later.

Good luck,
Joe
