hi,
open and close front door cover to reset error.
If it persists you have to execute (TCR Toner SUPPLY)
Tell me if you need to execute it.
Bye.

Theres a service code to run the calibration program to reset the colors. It should be ran by a technician because that machine is very picky about running the procedure the right way. If someone shortcuts it, it makes a big mess.
With three error codes on the screen, it won't be something easy on your end to clear it.

Reset it, start it with the right door open, go to service mode, clear the counters for drum and developer and go to functions menu. Close the right door and start immediately the F8 function. It should work.

Utility/Counter -> Details -> [STOP][0][0][STOP][0][1]
Go to counter and clear the life of the developer and drums and then run F8 from functions.
