| Black Copies on KM / CS 3050 4050 5050 All the black copies I ever had with the 3050, 4050 and 5050's was always due to the Main Charge Corona Unit. I usually remove the motor that cleans the corona unit, because they fail a lot, and leave the one gear that drives the corona wire and grid cleaner. Remove the Corona Assembly and clean the grid and wire real good with alcohol. If this resolves the problem, make sure you keep a Corona in your Car Stock. If not could be the Main Board. Check to see if you get print while in simulation 1087, 1087, maintenance 000 and print. If you get a print in simulation could be the board. Check to see if the scanner bulb is coming on. Black copies can also be caused by the laser unit but you'll get a code. Most likley it's the Corona... good luck. |
