Description: 917.00 Transfer service error 917.01 Transfer servo result too low.
Code: 920
Description: 920.00 Under temperature during steady state control. 920.01 Fuser took too long to heat up after transitioning to new enhanced mode. 920.02 Fuser fell too far below desired temperature while printing. 920.03 Fuser too cool while checking for slope change. 920.04 Fuser too cool when heating to desired temperature after slope change. 920.05 Fuser under temperature while printing 920.06 Fuser under temperature while printing 920.07 Fuser under temperature while printing 920.08 Fuser temperature did not increase after IR recovery. 920.20 Belt fuser under temperature during steady state control. This can occur in printing or standby modes.
