SC 670 - Engine response error. After powerig on the copier machine,a respons is not received from the engine .possible defect controller board or SBCU installed incorrectly.Try reset the code to turn ON/OFF the main power switch.
Hi, it looks like a bad controller board. Try resetting it from in service mode with 7807. Also if you can view or printout the error history with 5990-004 for further trouble shooting. Hope this helps
Well, that is not an easy error. Your machine is detecting a short circuite in the discharge plate. It could be just a defective harness between the High voltage supply unit and the BICU.
So... The best advise i can give you is to call your technical support.
Transfer belt mark detection error
• The main motor is operating; and
the lock signal is detected. → The
belt mark sensor signal does not
change for 120 milliseconds.
• Defective main motor
• Image transfer belt out of position
• Belt mark blurred or absent
I would remove the pcu unit (3 screws)and check the transfer assy belt mark and clean the sensor that reads the belt mark. Worst case senerio is replaceing the entire pcu unit.
Well, I have no idea why changing your password would affect it this way. the code you're experiencing is a fuser warm up error, due to blown fuse, thermostsat, possible power supply prob...regardless, it can only be reset by a service tech in service mode once the problem is fixed. Sorry.
Hello sir; try to turn off and back on the machine to reset, if don't work next few steps need to follow;
1, press "clear mode" then enter 107 then press and hold "clear/stop" key until SP mode show up.
2, turn power off and back on .
This SC code relates to the charge corona cleaner not working or not working properly. the charge corona is located towards the bottom left of the machine after opening the front cover. It will have a screw you can undo by hand and a cable with an end like a telephone cable plug. toner may have fallen in to the unit or the motor that drives the cleaner along the wires has decided to jam up. remove the charge corona and blow it out with compressed air. You can also remove the end of the unit and check that the motor is not gummed up. Be very careful you do not break the hair thin corona wires! Hope this helps.
