B2.3.2 Major Trouble Errors
B2.3.2.1 Fuser Error
The fuser error indicates an error in thermister on heater.
In case the fuser error occurs at the time of printing, the heater is turned off soon but the printing contin-
ues of that page.
However, if the error occurs before the write sensor is turned on, the motor stops soon.
B2.3.2.2 Fan Error
The fan error is generated when the FANSNS signal lead goes "1" while the fan is running at full speed.
Operation of the FANSNS signal when the fan is turned on is described below.

Since the fan alarm is not monitored during printing, the fan alarm does not appear from the moment the
printing is started until the completion of printing operation.
In other words, the printing will continue even if the fan alarm occurs during printing.
