How to Remove and Replace Linear Bearing Blocks on SP VP XC VS LEC Rail

[graphicsphere]

Hi I have a VP-540 that I need to replace the cutting carriage and print carriage L-bearing blocks since its binding and is really hard to move freely along the rail.

So I'm trying to find a good how to video or instruction manual so I can see what parts I need to remove first before I replace the L-Bearing Blocks. Is there one bearing block for the cutting carriage and one bearing block for the print carriage? How many bearings do I need to replace and what are the Roland part numbers so I can order them?

Can anyone explain how the L-Bearing Blocks are removed off the rail? Do I need to remove all printheads from the print carriage first? What else needs to be removed first?

Thank you

The cut carriage has one bearing, and the print carriage two. To remove them you need to remove the carriages from the bearings, they are held on with large hex bolts at the back of the carriage and are easy to identify ( It is easier to remove them if you take off the top printer cover and screen to give you more access). You don't need to remove the heads, you can just undo the carriage to allow the bearing to be free from it. Move the carriages over to the middle of the printer to get the best access.
It is best to remove the dampers and head cables ( Unplug the machine from the wall and leave at least 15 minutes before removing any cables ) as this makes it easier to get to the hex bolts

Once you have done this you can remove the left hand cover and slide the bearings all the way to the left, there is a plastic stop you need to remove on the rail and after doing this you can slide them off the rail.

It is a pretty straightforward job, but after replacing them you will probably need to run the print and curt alignments as the carriages can be in slightly different positions

Thank you that makes a lot more sense. I’ll get the linear bearing blocks out and see what exact part numbers they are. I wasn’t sure if I needed to remove all the heads first because that would take a lot more time to reinstall.
