Exposure lamp the bright light under the big glass is burned out, try reset, by opening front door look to your upper left small access plate remove it this must be done with machine on. press the reset button if the code goes away OK.

The C0400 deals with the scanning lamp not turning ON. I would check the fuse for the scanning lamp and check the lamp to see if it is blown. You will most likely need to replace one or both of the parts. Good Luck

C0400 -Exposure lamp failure to turn ON
C0410 -Exposure lamp turning on at abnormal timing
Turn OFF the copier,remove the glass,Work a screwdriver trough the hole in the frame at the left front side of the copier and remove the screw that secures the scanner unit.Move the scanner to rhe right hand side of the copier.Remove 3 screws to free the scanner.(To remove the scanner turn it counterclockwise).Remove 1 screw and the wire guide,remove 1 screw and the ground wire.Unplug the exposure lamp terminal connector,unplug the thermal fuse connector.Remove the scanner from the copier.Verify the continuity of the exposure lamp and thermal fuser.If is defective change.

Well the C0500 code is the code that is given when the fusing unit is bad (THE HOT PART) to reset that code need to go to the rear remove top rear cover and press the small black button on the control board lower left. The C0400 is Exposure Lamp the bright lite under the big glass. Might need to get a new one try web site below as for the C0500 if it comes back do not reset get Konica Minolta rep to look at the fuser unit. IT can catch on fire and that would ruin a perfectly good day. If parts required see the web site below for a start Precision Roller Printer Toner Cartridges Parts and Supplies Office...
