Re: Ricoh mpc3501
Is there any print engine activity / movement on power up?
If there is try accessing the web interface and seeing if there is any error code displayed.
If it just sits there with a green light and no engine activity on power up it could be number of things.
- Missing voltage range / check blown fuse conditions on the PSU.
- Faulty PSU
- Faulty controller
- Faulty polygon mirror motor / BICU
- Knowledge not shared, is eventually knowledge that becomes lost... like tears in the rain.

Re: Ricoh mpc3501
If you can access WIM, check the status for error codes. SC 202, SC 203 or SC 204 would indicate a blown polygon mirror motor. On some models, the polygon mirror motor will also take out the BICU. Replace both as a set to prevent blowing the new part if you only replace one.Comment

Re: Ricoh mpc3501
Hi there!
Take a flashlight in an angle of ca. 45 degrees & look if can see the errorcode on the display. As slimslob mentioned the BICU/polygonmotor you can see the error-code with this trick.

Re: Ricoh mpc3501
Taking a solution from a previous thread...and we used successfully.
If this is a SC 202 resulting from a bad polygon and the BICU has also failed.
Take a look at the BICU for a tiny resistor (very tiny) near the lower right power connector. There is a row of them, they all have a "0" printed on them, except for the one which is "burnt"
If your good with soldering, there were some who have replaced them. I just soldered across the resistor and has been good for quite a while now. ( I did replace the polygon to prevent another failure)
Figured it would need a new BICU anyway, nothing lost in trying.Comment
