Other Control Features

The printer has the following useful features;
5.6.1

Sleep mode

When the printer does not receive data for a certain period of time (timeout), it enters sleep
mode. The default timeout is 5 minutes and it is automatically adjusted to the most suitable
time-out setting depending on the frequency of your printer use (Intelligent Sleep Mode).
While the printer is in sleep mode, all the LEDs are off and it is as if it was turned off, but the
printer can still receive data from the computer. Receiving a print file or document
automatically wakes up the printer to start printing. Pressing the button also wakes up the
printer.
NOTE:


When the printer goes into sleep mode, the fan will not stop until the printer engine has
cooled down. The fan running time varies depending on the sleep mode timeout because
the fan running conditions are defined as follows;
1) The fan runs for 10 minutes whenever printing finishes.
2) The fan runs while the printer is in ready status.
3) The fan runs for at least 5 minutes after the printer goes into sleep mode.
(EX: If the timeout is 5 minutes, the fan will be running for 5 minutes after the printer goes
into sleep mode.)


Sleep mode allows the print engine to cool, so the temperature of the room and how long
the printer has been in sleep mode affects the warm-up time. This warm-up time can take
up to 45 seconds. The Ready LED blinks to indicate that the printer is warming up.


You can change the timeout for the sleep mode with the supplied printer driver (all models)
or Remote Printer Console program. The time-out setting is in the range of 1 to 15 minutes.
Refer to the Help section in the printer driver or RPC program for more information about
the sleep mode setting.
Description
If the button is pressed during printing, the printer immediately stops
printing and ejects the paper.
If the printer is in sleep mode, pressing the button wakes it up into the
ready status. It will take up to 45 seconds for the printer to go into the
ready status.
If the Data LED is on, press the button. The printer prints any data
remaining in the printer memory.
If an error occurs, the printer will recover from some errors automatically.
If the error does not clear automatically, press the button to clear the error
and continue printer operation.
You can reprint a print job without sending it from the computer again.
When you press the button with the Data LED off, the printer reprints the
last job you printed if the whole job can be kept in printer memory. If the
print job is too large or there is insufficient memory, the last page only will
be reprinted.
