Engine Error Ignore Mode; One Push Print Recovery Mode - Brother HL-5440D Service Manual

1.4.6 Engine error ignore mode

When an engine error occurs and the machine cannot be recovered unless the main PCB is
replaced, using this function enables the machine to start, ignoring the engine error, to retrieve
the EEPROM data.

1.4.7 One Push print recovery mode

The One Push Demo function allows you to perform Demo printing by pressing the [Go]
button (mainly used for sales promotion at dealers). However, the One Push Demo function is
disabled once printing is performed from the computer. Entering this mode allows you to
restore the One Push Demo function. After restoration, however, the contents of Demo
printing will be the same as those of test printing.
