MPC 300 SC240

**limo** · 04-17-2013

For me the problem was with the laser unit.Replace it with one from a defective SPC430 eventhough the p/n is different the unit is the same.

Interesting to see this. I saw some sort of alert mentioning that with either 240 or 241 to consider replacing the laser housing unit and the power supply together. No mention of boards being an issue.

Not like Ricoh has not been having some "wires rubbing on the frame" issues here lately.

I just helped another tech with a SC241. Didn't see any wire issues. Replaced the DC power supply and laser unit and machine was fine.

Old post I know! but I have a brand new laser unit for this MPC300/400 & also fits the SPC430, if anyone needs it let me know can ship worldwide.

A new laser will fix the SC240 error issue.

Make sure you fit the modification too otherwise it'll just do it all over again. M026 9904.

Maybe this bullitin can help you:
RM028047SC
Change the LD unit and install these pcb kit M0269904
it´s a modification for the sc240 (see RM028047SC from Ricoh)

I've just had this code pop up on a machine myself, and am away for a few days and unable to attend the call.
I have someone that can fit an LD unit for me, which sounds like the main problem.
My question is:
"Should" that resolve the problem temporarily (for a week or so) until I can get back and fit the Modification, or is the Power supply typically damaged and will take out the LD unit right away?

ALSO..any chance it coould just be a k- PCU? It is actually a bit overdue for one

Thanks!

It should Sandy, it has for me. After eating the cost of a new LD unit a couple of times, I went ahead and put the mod on all my c300's in the field.

Thanks Mika!
Replacing the LD unit has fixed it for now. I'll decide what to do when I get back.
I had a parts machine to harvest from, but I'm also lucky that I live so close to a massive machine wholesaler that's very good to me when I need replacement parts like that.
