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.

Sorry, but I think your laser is dead ... :(

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.

  1. Go to this code with "Clear Mode"+107+"Clear/Stop" hold for 5s.
  2. Go to System Settings
  3. Go to 5875
  4. Check the setting of SP5875-001. If the setting is set to "1 (OFF)",change it to "0 (OFF)".
Try checking or changing the thermistors!
The metal contact spring on the thermistor broken causing all sorts of 'unrelated errors including 'Please Wait' sc 670 and sc 402...

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).
