Ricoh MPC5501

**scanmc** · 10-09-2018

I don't do a lot of work on Ricoh's but I've got this one out in the field. My issue is when duplexing the machine gets about an inch out of the fuser when entering the bridge then jams (J024 code) I pulled the exit assembly from a very low meter parts machine and installed it with same results. Machine will run all day on simplex. Any help would be appreciated.

has it printed on both sides, then misfeed as it exits or is it flipping the page over when it misfeeds?

J024 is a Junction Gate Sensor. I would suspect maybe the junction gate is "cracked" from heat from the fuser, and allows those teeth on the shaft to move or fall off. Or maybe the "arm" on one of those guides (that the solenoid engages with) may be broke or missing.

Agree... It happened to me already

Replace D029 4580.

This. Ricoh refers to it as an "open/close guide" and they released a TSB for this.

Well It ended up being the gate shaft and bushings were so gummed up that the solenoid would open or close properly. After a good cleaning she's working like a champ again. You would thing after all the years of doing this I would remember the KISS rule.

Thanks to all who responded!
