Mpc3001 sc531

[mrfuser]

Ok got the sc531. Changed both fans by the fuser. It will run a single page no problem, but as soon as we try 3 duplexed pages we get another sc531. Any ideas?

Re: Mpc3001 sc531

Wrong fans. The fan you need to replace is Ventilation fan(s) at the left side of the machine. The fusing unit is at the right side of the machine. See Airflow fans under Laser Optics in the Replacement and Adjustments portion of the service manual.

Here's one!

How about stating that problem in your first thread from 2 hours previous to this one:
Mp c3001 exhaust fan part

.....And then, returning to that same thread to update us about your failure, and ask for more help, rather than starting a brand new one!

You actually expect that much out of mrfuser?

Foolish me. I can't set the bar low enough!

Re: Mpc3001 sc531

I’m sorry to have offended you gentlemen that was not my intention. I was figuring because I had two different questions that I should open to different threads but if the consensus is not to do that then in the future I will not

I certainly hope that no one‘s feathers were to ruffled

so the two fans on the left side of the machine by the laser assembly are the problems eh?

My bad 531. Other fan SC would be

530 - fusing fan
532 - IH Coil fan
533 - IH inverter fan
534 - Second duct fan
535 - Paper exit fan
536 - Third duct fan

Re: Mpc3001 sc531

I replace the two fans on the left side the front fan comes on no problem but the real one will not come on and I tested the rear one on the front and it comes on just fine

any other ideas on this gentleman?

Re: Mpc3001 sc531

531
- Defective ventilation fan motor-front or rear
- Defective IOB

So, if you ruled out the fans, and checked the connections, the IOB is your next suspect - D0895123 PCB:IOB
