My Gestetner DSm622sp says it has a hard drive problems, codes SC870, 872 what do I do

Go to SP Mode and Switch OFF and On the machine if the problem not solved change the thermistors - thanks

change the thermistors

It is software loading related. It could be you need to reload the machine firmware, replace the hard drive or the RAM.

sc546 is a fuser temperature detect error. One or both of the thermistors most likely need to be cleaned or replaced, but you will have to go into service mode to reset the code once you do that. You should contact your local service technician or Gestetner dealer, as they can easily fix that problem.

Most likely this is a hard drive failure. This is especially likely if your machine has the network print and or the document server and fax options installed.
If you let it sit with "Please Wait" long enough does it ever come up with the wrench light or service code?

Fusing unit problem.Verify the heater lamps,thermistor and thermofuse continuity.Enter in the SP mode turn OFF the main switch,unplugged the machine wait 10 sec.,plugged and turn ON the copier.

hi
on the screen there should be the letters ''SC'', followed by numbers.that code will tell what the problem is.

Hello sir; the error code you have display, that's means laser motor don't work, replace it!

Fuser error (warm up error). Needs to be repaired, then the code can only be reset in service mode.

Open the front door and close it and check if the display reads loading toner. Try this for 3 times.
If Add toner indicator is still there, check that you had removed the black cap of the toner, before you replaced the toner bottle.
Remove the bottle from the holder and check inside the neck of the holder if there is something blocking the toner supply. (sometimes the inner plastic cap of the previous toner is stucked in the neck).
Check and clean the toner bottle holder unit.
Another problem can be worn gears in the lower development unit and within the dev. bias roller.
Good luck and please rate me, thanks.
