features described below.
Built-in Print Server
This machine has a built-in print server as a network interface. When you use the print server, you can send printing
data to the machine from anywhere on the network.

2-1 Switching the Power On and Off
Switching the Power On and Off
This machine has a main power switch and a sub power switch. Switch on both to use the machine.
Whenever printing is finished, switch off the sub power. You also flip down the loading lever to the rear of the ma-
chine.
Leave the main power switch 
➀ on at all times, never switching it off. Leaving it on activates the alarm feature.
 P. 64, Alarm Feature
WARNINGWhen printing is not being performed, remove any loaded media or switch off the
power.
The continued application of heat at a single location may cause the release of toxic gases
from the media or pose a fire hazard.
Important Note on Switching Off the Power
Never switch off the main power or unplug the power cord
suddenly while operation is in progress. Doing so may dam-
age the print heads. Be sure to first switch off the sub power.
If the main power is accidentally switched off, immediately
turn the power back on.

The Power-saving Feature
This machine is provided with a power-saving feature that switches to a low-power sleep mode when a fixed interval
passes with no operation. The factory default for the time after which the machine switches to the sleep mode is 30
minutes.
You can change the setting for the time of the shift to the sleep mode. You can also switch off the power-saving feature.
 P. 78, Setting the Interval until Activation of the Sleep Mode, p. 78, Deactivating the Sleep Mode
When the machine is in the sleep mode, the sub power switch flashes slowly. Using the operation panel or performing
operations such as sending printing data from the computer (when media is loaded) restores the machine to its normal
mode.
To reduce power consumption and prevent problems such as overheating, we recommend leaving the power-saving
feature on and setting the activation time for the sleep mode to 30 minutes or less.

2-2 Loading and Cutting Off Media
Usable Media
For information about media that can be used with this machine, refer to the page indicated below.
 P. 118, Conditions for Usable Media
Loading Media
Media may be of one of two types: media wound onto a paper tube (called “roll media”) and media not rolled in this
way (called “sheet media”). This section explains how to load media, using roll media as an example. For information
on how to load sheet media, refer to the page indicated below.
 P. 76, How to Load Sheet Media
CAUTIONLoad roll media correctly.
Otherwise the media may fall and cause injury.
CAUTIONRoll media weighs about 30 kg (66 lb.) to 50 kg (110 lb.). Handling roll media is an
operation that must be performed by two persons or more, and care must be
taken to prevent falls.
Attempting to lift heavy media in a manner that taxes your strength may cause physical
injury. Also, if dropped, such items may cause injury.
CAUTIONNever load media that exceeds the loadable weight.
The machine may fail to withstand the weight and tip over or cause the media to fall.
1.Load roll media and align the left and right sides.
Open the front cover.
