The best way is to update the firmware in the copier. You have to download the current firmware and put it on a flash card and and plug it in to port 2 after powering down the copier. Power it back on and the firmware will set itself up to your copier.

SC390 = Toner Density Sensor abormality

Possible causes:

  • Poor concentration of developer
  • Toner density sensor faulty

Are the prints/copies coming out ok? If the copies are very faint or heavily overtoned then changing the developer may cure the error code. If the copies look OK then you probably need to get the toner density sensor replaced by an engineer.

Hope this helps.

No such code for that model. But the 500 range you mention is fuser related. Replace the fuser....but parts are no longer made for that model...it was made in 1999.

Most of the time is trash on the network.
Also SC990 sometimes occurs if the signal timing during scanning and printing causes a delay in the process.
There is a firmware that fix this error. You need to download it (if you know how to do it of course).
