[Error Code] Ricoh Pro C5110s SC689

[Bricorley]

Hey guys, Just did a fuser rebuild on this unit. It has 900k on the clock. Well after reinstalling the fuser im now getting SC689 (SM says IH Inverter Board Communication). I rechecked my work and found nothing wrong. SM advises Inverter board replacement or IOB. Anyone else have tHis issues before? I checked the IH coil harness, re-assembled the fuser, reseated both inverter/IOB and checked power supply fuses. Ive already both boards and waiting for them. Any help will well help. Thanks

I never had to work on one of these before I retired, but I remember that older models had a thermostat mounted on the IH coil assembly. At that time Ricoh did not show the thermostat in the parts catalog as it took a major tear down of the IH coil assembly just to get to it. If it popped, it was the same SC code as for an open IH coil or bad harness.

I have a 5110s with 750k on the clock fuser is now over life but working fine.

Can I ask how long the rebuild took you? It was half a day on the course not done one since!

(Sorry this dont relate to your post!)

Thanks fellas. I checked for continuity and it was a dud. Gave it a small smack and presto! Why cant Ricoh just program a SC thats thermostat specific. So annoying.

Thank you so much.

Its solve the problem.

SC689-00.


Thermostat have NO connectivity when checking with Multi-meter. The little metallic plate over this thermostat-sensor go inside.

i have to drop this sensor on the floor couple of times, then metallic plate comes outside, and show connectivity when checking with multimeter, after reassemble into fusing unit. Machine is fine and working.

Thank all of the forum participants for there help in this regard.
