Help Needed

[weeker2014]

Does anyone know anyone locally who fixes photocopiers? Model is a Ricoh MP C4000, quite a few errors and jammings :( Not interested in a big company like HOE unless engineer as a homer.Any info would be appreciated.Thanks

[captain chaos]

What error codes are on the machine?
Can you send me what are showing in a PM amd might be able to help

Below is a list of most common Ricoh error codes spread over the next 3 replys as tooooo long for one reply


Ricoh photocopier/printers error codes can be divided into three levels (A, B,C). The “A” level codes have high risk and involve the fusing unit problems. The machine operation is disabled. Only a service engineer should reset and repair this error. The B level errors are caused by one or more specific units. The machine operates as usual, excluding the related units. The C level errors have no effect on machine operation except to display a warning on the control panel. Error levels can be checked in service manuals under “troubleshooting” section.
SC543, SC545 codes:
SC543, SC545 are most common errors in Ricoh products. These errors indicate a problem in fixing temperature or thermistor. It is strongly recommended to call an authorized technician to reset and fix this problem because defected parts must be replaced/repaired before resetting these errors otherwise it may result in fire or other damages.

Error Code List:
Ricoh error codes are generally categorized into 9 categories. Each category starts with a unique number starting from 1 to9. A brief description is given below:
