Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

This problem relates to the Main Motor Drive on the printer.
The L4 error details that the Motor Drive has been Overloaded.
Try disconnecting the power and blowing it out with air-cleaner

L4 means that there is an overload in the drive system. Check the developer unit if its running smoothly or the drum. Make sure the exit unit is not jamming. This can be done by openning the cover on the right side and you will see a small motor. Clean its sensor.
