MP 7000 black screen and sc 202

[kalaris]

Hi! A power-MP 7000 dark screen and code sc-202. I checked the connections and disconnect the motor without resolving prism. Has anyone had the same problem? Thanks

Many of us had the same problem. Polygon motor and controller to replace at the same time.

Even after replacing the envelope containing the IPU controller etc.. the problem is not solved. You can barely see the code 202 through the dark screen ....




Any suggestions?
thanks!

You say IPU board,etc...I asume etc=polygon motor?
If you changed IPU board and Polygon motor then I'd say problem is PSU board,it happened to me once on MP7001.
I powered on imported used machine in workshop and PSU board fuse got blown,after I replaced fuses it showed me dark screen with SC202,I replaced the PSU board and it worked like a charm.

Another cause I've have for this is the side gates in the LCT harnesses chafing, wearing through and arcing out, dropping machine causing SC202. Pull all the trays open and switch on. If it comes to ready, that's your cuplrit. I had it on an MP5500.

I suspect too that it's a problem of tension and I want to try replacing the power supply board although in this case the fuses have no problems. I'm afraid that might be the card Bicu I do not own. Even disconnecting the fuser unit and drawers do not change anything.

Doesn't has to have blown fuses...I replaced fuses and only then culd I power on machine to see what's wrong with it...Blown circuits was the problem

Resolved. Thanks for the advice. I replaced the main power board and the polygon motor and it works.
