mpc 5503 jammed

[copier tech]

Its finally fixed.. The problem was the BICU type H board. The little one that attaches to the BICU. After I changed that it threw up an SC202 so I changed the poly motor and it finally ran a copy and no more C jam. Now to put the machine all back together. I swapped so many boards around. Its a good way to end the week.

All these parts for a simple jam 🤔

Sounds to me like it was just a loose connector.

The initial problem most likely was the polygon mirror motor. A failed polygon motor can take the BICU. Any time you have a BICU fail, replace the polygon at the same time.
