I keep getting error 116-357 on my Xerox versalink C7000 - What am I doing wrong

This error code could indicate an issue with the drum or fuser. Ensure that the toner cartridge/drum has been seated correctly, and if necessary contact a qualified technician or Xerox support to further investigate and resolve the issue.

Turn off the printer and the system then remove the cables that made the connection in between them.
Open the upper cover and remove the printer cartridges.
Clean the cartridges clearly and make sure no dust or extra material should be there inside the printer.
Make connections once again then turn on the device and print a test page.
If the issue is not resolved then chat with our expert

This show in the manual but some time only need shake the toner

It is because of drum failure, especially caused by communication, better to reinstall window and install your driver. It will erase all unnecessary file from the cache.

If the main motor speed feedback signal does not appear after 2 sec from the main motor.or If the copier does not communicate with the sorter for at least 12 sec. cheek Sorter controller PCB or DC controller

19,003.48 Scale and offset voltage error too large. Something is wrong with the Electronics Module or Wave Amplifier.

that is pretty straight forward. More then likely the elsctronics module has failed. Wave amplifier is pretty unlikely.
If you do not have a maintenance agreement or under warranty, that is a very expensive module to replace.
Check @ 1-800-835-6100 to see if you are under warranty or have coverage.
