mp4001 sc544/sc554

[dankaboy]

hi guys,

i have got a ricoh mp4001 black and white copier that has only 10k on the meter with two intermitant error codes sc554 and sc554, thermistors/hot roller in perfect condition and firmware up to date.

had those codes on a mp4001 along with a bunch of other codes. replaced the IO board and they went away, then came back a month later. replaced the fuser exhaust fan and another exhaust fan and they haven't come back since.
