Possible that the INDETECT paper sensor is not working. Sometimes this can be an opto sensor, If so you need to remove and check using a multimeter and replace the component. It can also be due to a jammed roller, a failed motor drive or a faulty motherboard .
If you feel adventurous, pull the AC plug and remove the lower panel in the rear.
Using a good light, inspect the area around the circuit board(s) and look for traces of paper and possibly a cylindrical component that has obviously burst.
A part that is prone to explosive failure is the electrolytic capacitor. These are not costly parts but if it is a larger one, there is a chance that it failed as a victim of another component failure, possibly a semiconductor called a rectifier which can be in any number of different packages that a technician is much more likely to recognize than a layman.
Replacing a failed capacitor without doing further troubleshooting is not a good idea; it could just destroy the new capacitor.
Possible that the in-detect switch/optocoupler detect is sensing a fault.
Check on the paper feed section for the in-detect sensor and make sure that it is reading into the paper. If there is no issue in this section the voltage change on the sensor must be checked with a multimeter as the paper is inserted.
if absent replace the sensor or otherwise the fault is in the main board which can be a digital switch failure to the processor..
C0960 Bypass lifting motion failure.To fix this problem, check that there is a clear paper path. The take-up roller has possible not returned to the 'home' position. Turn off the copier, manually rotate the roller to check that it is free. Turn on the copier, once start-up is completed, check that the paper path sensors are clean. Close the by-pass tray and open again.If this fails to reset the code, refer to your service technician.
this is a tray 1 lift up failure code pull the paper tray out and check to see if some torn paper is blocking the lift sensor look around where the paper is fed into the feed plates if not it could be a failed lift motor or sensor and they will need to be replaced
Take out your paper (check if you are loading the roll from "underneath" and not from the front) . Switch off and on. If the machine gives you the same fault again, press cancel for about 2 seconds, it should then go to ready mode. If it does not then you have a carrage sensor failure. In any case the sensor is failing and its finding it difficult to find the paper. Its a bit technical but if the sensor fails you will need to replace your carrage (head) unit
If there are no obvious paper pieces stuck, you could have either a problem with the dirty or worn rollers in the ADU, a dirty or defective sensor, or most likely a clutch problem in the ADU. Likely will require a service tech on site to repair to no obvious defects are seen.
