I keep getting sc 555, 542, 545 on this unit i have replaced the thermistors with the updated versions as well as the updated brackets, i changed the heat roller which had some wear on it, i am at a friggin loss here and the boss is riding me because this is at his lawyers office, any ideas?
Have you replaced the thermostats? How long does the machine run for until the code reappears?

We have found what appears to be a solution for these codes. Change the following:SP1-103-001 to 60, 1-103-002 to 60, 1-103-003 to 120. Lower all fuser temps by 5-10 degrees. Hope this helps.

I'd do the firmware too, just as a precaution

I followed the post by Kyle731 and it corrected my sc 555 problem.
The sc 545 was resolved by replacing the fusing unit main harness/connector.

thanks guys the problem is intermittent, about every 5-8k which is 2-3 days for them
I can't see Kylies response? what was it?Originally Posted by Ricoh-ono
This is what he said.
Step 1:
Check the lamp connectors (females specifically). From the factory they split and are not making good connection. I took my tweaker and pinched them so they were tighter. Depending on which lamp connectors are loose, you will get either 555 (fror the one lamp) or 546 codes ( for the other lamps). When I cheated the front door and would play with the lamp connectors I could get the machine to pop those codes, that is how i knew those connectors were an issue.
Step 2:
Per Ricoh, disable the 'panel off timer':
1) User tools
2) System Settings
3) Timer settings
4) Panel off timer, turn to off.
In addition to the info above I max out the energy saver modes. make sure all fuser idling modes are active, and use the latest thermistors (skinny ones).

the part where kyle731 mentioned about the connectors is new to me. Got to try it out.
