I have a new C552 with C3722 code. I can reset the code, but it comes back. I monitored the fuser temps in Service Mode, the temps are all over the place on Edge,Center and NC sensors. Don't see break down for fuser unit in parts guide. I would hate to have to replace brand new fuser.Any other suggestions?:confused: DC Trouble
Does the machine work for a while before the code come back again?

Yes, for a while meaning a day. I thought about it some more. It could also be a bad connection between fuser and PRCB. Still open to other ideas.

there are three ir sensors on the copier frame. try tradeing their positions around. i think the one on the back side of frame is only used when the other 2 fail. redundant thermal protection.(remove fuser and you will see plastic bracket they are mounted in)
Yes it should be one or more of these sensors.

<Workaround>
Change the setting time of Low Power Mode setting as longer than the time of Seep Mode settings.
Administrator Settings -> System Settings -> Power Save Settings
-Default settings
Low Power Mode Settings: 15 min. Sleep Mode Settings: 30 min.
-Workaround (For example)
Low Power Mode Settings: 35 min. Sleep Mode Settings: 30 min.
-Note
Sleep ON/OFF Choice under Service Mode has to be set [Prohibit] as default settings.
System1 -> Sleep ON/OFF Choice: Prohibit
<Countermeasure>
-Temporary measure
