Roland Xj740 Sheet Cut Assembly
Hi
I’m after a bit of help with the sheet cut assembly on my Roland XJ740.
It packed up a while ago and the last time our engineer was in he looked at it just before he was about to walk out the door and told me it was a simple fix, I just needed “a new screw”. Time passed and I’ve completely forgotten what I need to do.
All the bits were taken off and taped to a piece of scrap dibond so I should have everything except any idea how to reassemble it.
The spring mechanism is working fine, but I have no idea how the blade engages to stay down to cut.
Any advice would be greatly appreciated 😀
Thanks, Paul

Does this help?

Hi Paul, The blade engages when part 12 in Stafford’s diagram hits a stopper inside the left panel when the carriage travels to the far left position. It cuts on the return pass and then disengages automatically.
-
brilliant, thank you both very much 🙂
-
I’ve reassembled it and when the carriage moves over the maintenance cover the cutter hits the stopper, the blade moves down but as soon as the carriage starts moving back towards the right the blade springs back up.

I’m not sure what’s supposed to keep the blade engaged? Before I fixed it back onto the head carriage it was moving freely, but it never ‘locks’ in the engaged position.
Any idea where I’m going wrong?
Thanks for any help you can offer 🙂
-
Have you run the ‘limit and cutter down position’? Also, if you take the left side maintenance cover off, that will make it retract. Might be a hint?
-
I’ve just run ‘limit and cutter position’ but it’s still doing the same thing.
Not sure what you mean about removing the maintenance cover, or rather why it would help?
Thanks, Paul

I’ll try and get a video when I’m in the office later…

I know it’s an SP but I’m pretty sure the mechanism on an XJ works in a similar way.

thanks so much for your patience!
The blade just isn’t staying down at all, as soon as it moves away from the stopper it springs back up. I’m wondering if I’ve assembled it incorrectly, or there’s something missing.
If I manually push part 12 on your diagram to the right should the blade stay engaged? Mine doesn’t stay engaged, this is with the carriage over the capping station: https://www.youtube.com/watch?v=MyzDwI9 … e=youtu.be
Thanks again 🙂

Sorry Paul, I’m out of the office again and not seeing another Roland for a couple of days. I’ll have a look when I can.
