Never heard of this happening to five machines before.  Check the connections in the laser unit.

SOURCE: machine shows a service code of sc 928

The SC - 928 is a Memory error problem.
The machine detects a discrepancy in
the write/read data during its write/read
test (done at power off/on and at
recovery from low power or night/off
mode). To try to reset this code -- Turn the MAIN power switch off, wait about 30 secs. then turn switch back On.

Possible causes:
• Memory defective
• BICU defective
• Poor connection between BICU and
The cheapest repair would be to replace the memory. It is rare the the connections came apart unless some one was in the back of the machine for some reason.

Thermistor defective or out of
position (replace thermistor)


Printer Ricoh sp 210SU "service call error SC491". using compatable cartridge instead of Ricoh original. Service centre suggests to change the cartridge to solve the issue. any idea else pl share me

SC491 on a Ricoh SP 210SU is a code for bias leak.

The machine detects that a bias leak has occured from the drum charge, development charge or transfer charge.
PWM signals are sampled at 20 msec. intervals. This SC is issued if 10 PWM samplings within 200 msec. are abnormal.

• HVPS (high voltage power supply) harness loose, broken, defective
• HVPS board defective
• AIO terminal defective (the terminal for the toner cartridge)
• Cycle the machine off/on
• Check all the harness connections of the HVPS
• Check spring-loaded AIO terminal installation behind the HVPS.
• Replace HVPS.

Usually this error is related to the cartridge. Some manufacturers of compatible cartridges will replace the cartridge with a new one.
At least they should give a discount based on how many pages that was printed before it failed.

I have not seen this problem with a new genuine Ricoh cartridge.
It is important that the cartridge is not refilled more then 3 times. There is no counter on this, and companies that refill cartridges they collect (with unknown number of cartridges) may have problems quite often.
