(during start of EWC/line voltage detection).
121.11 Fuser reached the required temperature (during
final EWC/line voltage detection) too late.
121.12 Fuser did not reach the required temperature
(during final EWC/line voltage detection).
121.13 Fuser reached the required temperature (during
final EWC/line voltage detection) too fast.
121.19 Fuser high power trace reached the required
temperature (during final EWC/line voltage
detection) too fast.
121.20 Fuser high power trace heating rate went over the
limit.
