More Features
The printer has the following useful features:
Sleep Mode
When the printer does not receive data for a certain period of time (timeout), it enters sleep
mode.  Sleep mode acts as though the printer was turned off.  The default timeout  is 5
minutes,  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 the printer was turned off, however the printer can still receive
data from the computer.  The printer automatically wakes up when it receives at print file or
document. Pressing the button also wakes up the printer.
2Note
· When the printer goes into sleep mode, the fan will not stop until the printer engine has
cooled down.
· Sleep mode allows the print engine to cool, so the temperature of your 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 will blink to indicate that the printer is warming up.
· You can change the timeout for sleep mode with the supplied printer driver (all models) or
Remote Printer Console program.  Refer to the Help section in the printer driver or RPC
program for more information about the sleep mode setting.

How to add extra Memory
This printer has 4 Mbytes of standard memory and a slot for optional additional memory . The
memory can be expanded up to a total of 36 Mbytes by installing a commercially available
single in-line memory module (SIMM).
Additional memory is useful and may be necessary if you are using the Page Protection
function.
It will also help if you are printing a page that is complex or at high resolution or is a complex
PostScript Document.
This printer can accept memory SIMM with the following specifications:
Speed 60 nsec - 80 nsec
Pin Type 72 pin
Height 35.00 mm (1.38”) or
less
Output 32 bit or 36 bit
2Note
This printer can also support a resolution of true 600 dpi and 1200 x 600 dpi under Windows®
95/98, Windows® 3.1x and Windows NT® 4.0 with the supplied printer driver. We recommend
that you expand the printer memory to avoid any memory full errors.
2Note
The printer has only one slot for a SIMM upgrade. If you want to increase your printer
memory again after you have already installed a SIMM module into the slot, you must remove
the previously installed SIMM first. For example, if you had previously increased the printer
memory from the standard 4MB to 12MB by adding an 8MB SIMM and you wish to increase
your total memory to 36 MB, you must remove the installed 8MB SIMM and install a new
32MB SIMM into the printer.
