1,002.47: The lower 525-sheet feeder had an over-current condition. The lift motor or clutch may be shorted.
  • 1. Unplug all connectors to the feeder.
  • 2. Remove the feeder and inspect the connector.
  • 3. Replace any damaged connectors either on the feeder or engine.
  • 4. Reset and reconnect the feeder.
2,001.47: The print engine cannot detect the presence of the I/O Board.

2,006.65: This fault code indicates a problem with the printer program. ROM could not be loaded.
37,002.47:PEST Error - Printhead Left jetstack disconnect. The left jetstack is not drawing the expected power from the supply.
Devices sharing the printer’s AC circuit shared, such as a laser printer, a coffee maker, or a space heater, may be placing heavy intermittent demand on the AC circuit. This sudden inductive demand creates momentary AC voltage sag that causes the PEST test to fail. Verify the AC power source prior to troubleshooting these errors.

Toshiba Error codes

Toshiba E-Studio machines do not display service code automatically. To read a code you should press down the “8” key and the “Clear/Stop” key at the same time. All codes, except fuser errors are reset by turning the machine off and back on again. PM cycle counter can be set in 0,8 mode, turn on the machine while holding down “0” and 8” keys, enter 251 to set PM limit, and 252 to see the number of copies that have been run since the last PM.

Ricoh Error Codes

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.
