Error sc 305 ricoh aficio sp 420dn?
Hi,
The SC 305 on a Ricoh SP 420DN is related to a AC bias charge error for the magenta color.
The machine sence there is a charge current that is less then
200 ?A is detected.
There are four reasons why this may happen.
• Defective charge roller
• Defective connectors
• Disconnected harness
• Defective high voltage power board 1
Follow this procedure, and see if that does the job.
1. Check the connectors.
2. Replace the PCU for magenta.
3. Replace the drum positioning plate.
4. Replace the high voltage power board 1.
Let me know if you need more info, part numbers and stuff like that.

yes you may it refers to a temp error int eh fuser... you may have a faulty thermistor or thermo fuse.. if you go into teh service mode by presssing teh yellow clear butto and then press 107 and then hold down the stop button the sreen will change turn the machine off and turn on again see if the errpr goes if it does it could have been just a temp error if it warms up then comes back on again you will have to look at the fuser.. you can check the fuser by touching the casing and see if it is warm after you have turned the machine back on..if it is warm the error could just be due to a build up of toner on the thermistor.. if you know about machines you can take the fuser out by opening the front of the machine up look to top right where fuser is there is a screw under the blue dial on the fuser take that out the fuser slides out put it on some paper and on the right hand side is the thermistors held inby a small screw if you take them out you may see some build up of toner on the resistor carefully clean this off.. put back together and turn on .. hopefully it will run ok.. good luck A

As NALDZ said, sometimes when the power drops out the thermistor will play up a little. Sometimes this can be caused by toner being caked up on the thermistor. But in most cases it can be reset easy enough.
if you walk up to the machine in COPY mode.
simply press.
(yellow clear), 1 , 0 , 7 (hold red stop button)
The screen will change, if you hold '#' on the keypad and press 'copy sp' on the touch screen you will be into ricoh service modes.
All you will have to do now to reset your error is simply switch the machine off at the main red switch below the plastic flap toward the bottom of the machine.
problem solved =]

This is a common error code for Ricoh copiers, Savin and Gestetner copiers that need service. Recently Ricoh has purchased Lanier and now is naming all their new machines Lanier instead of Gestetner, Savin and Ricoh. However, the copier service error codes have remained he same.
When you get this copier printer service code it means the fuser or fixing assembly (same part) has thermistor problem. The copier fuser's thermistors help regulate the temperature of the fuser assembly. The fuser assembly on all copiers including Canon, Kyocera, Ricoh, Sharp and other brands is the part that melts the toner onto the page.
Getting back to the repairing the copier on Ricoh, Savin, Lanier and Gestetner models that have the fuser or fixing code error. The majority of the time the fusers' thermistors (Middle and read) need to be replaced. Just cleaning them will not solve the copier repair service code.
It is usually, depending upon the machine, its a 1 to 2 hour copier repair job because the copier repair service technician will need to dissemble the fuser, insert the two new thermistors, re-assemble, reset the error code and test the copier machine repair. Also, ask the copier technicians to to do a copier cleaning maintenance while on site.
