16.5.6 C2152: Transfer belt pressure welding alienation
Have a tech come and re-flash the firmware, and check the NVRAM. Firmware is only available fro secure Konica Minolta Web site they like to keep they software secure. You mite also have a bad control board. Or the memory on the board, a Tech is required.
Replace any new toner you put in the machine and shut it down for 2 min then power back on. If that doesn't fix it you will have to call Xerox service to replace a sensor that may be broken.
You likely can't fix this yourself. Konica does list a solution addressing this issue but it will require a firmware update to your machine. There may be other causes as well. First be sure you don't have any HVAC vents aimed at the machine (particularly the exit side of the machine) as this is a fuser temp related service code. Contact an authorized Konica Minolta dealership and ask if they can update your firmware for you.
