Sleep Mode
Power saver mode is supported to save standby power. If Printer has been left idle or has not received
print data for a certain period of time or longer while it is in online or offline state, it enters Sleep
(power saver) Mode automatically. Printer exits Sleep Mode when Power key is pressed on Operation
Panel or print data is received from Host Computer.
Conditions for Entering Sleep Mode
Printer enters Sleep Mode upon completion of shutdown process under any of following conditions:

Sleep mode button is pressed from Printer Driver, except when there is print data yet to be printed.

Specified interval of time has passed while Printer is in ready state (default: 4 minutes and time to
enter Sleep Mode is variable from Printer Driver). It is assumed that Printer is in User Mode and
that Operator Call Errors have not occurred or that there is no print data yet to be printed.
*1. Except when Service Call Errors are occurring.
*2. Various error notifications are suppressed while Printer is in Sleep Mode.
*3. Not displayed in Status Monitor.
*4. Because Printer is unable to detect error clearing while it is in Sleep Mode, Operator Call Errors and
warnings existing at the time of its migration to Sleep Mode are cleared once.
