Theory of Operation
Recovering from Heat Error
Heat error is automatically recovered when the error is only caused by Low
Heat Error, and not the Heat Errors in Warm-Up state and the Over Heat
Error.
When an error occurs, the engine memorizes the present temperature.
In case of Low Heat Error, the maximum heat is supplied to the fixing unit.
When a specified time is elapsed, the engine detects the temperature again. If
the present temperature is higher than the memorized temperature, the error
is recovered.
In case of Over Heat Error, no heat is supplied to the fixing unit. When a
specified time is elapsed, the engine detects a present temperature again. If
the present temperature is a specified degree lower than the memorized
temperature, the error is recovered.
Low Heat Error When the engine is at Standby, Printing, or
Warm-Up mode, if the temperature of the
fixing unit is lower than the specified
temperature at each state and the lower
temperature state is maintaining during a
specified time.
When the error occurs, the engine stops all
functions and keeps it at error state.
Standby
■ Lower than -20° C for more than 10
seconds.
Printing
■ Lower than -20° C for more than 10
seconds.
Warm-Up End
■ Lower than -10° C for more than 10
seconds.
All LEDs blinking.
Over Heat Error For overall engine state, if the temperature
of the fixing unit is higher than the specified
temperature and the temperature state is
kept during a specified time.
When the error occurs, the engine stops all
functions and keeps it at error state.
■ It has been higher than 220° C for more
than 20 seconds.
■ It has been higher than 230° C for more
than 3 seconds.
■ It has been higher than 10° C for more
than 180 seconds.
All LEDs blinking.
