Important Notes on Handling and Use
This machine is a precision device. To ensure the full performance of this machine, be sure to
observe the following important points. Failure to observe them may not only result in loss of
performance, but may also cause malfunction or breakdown.
This Machine
This machine is a precision device.
Never subject the machine to impact or excessive force.
 Never needlessly put your hand or ngers inside the cover, the ink-pouch ports, or other
internal areas of the machine.
Install in a suitable location.
 Install in a location having the specied temperature and relative humidity
Install in a quiet, stable location offering good operating conditions.
The print heads are delicate.
Never needlessly touch or allow media to scrape them.
The print heads may be damaged if allowed to dry out. The machine prevents desiccation
automatically, but improper operation may render this feature inoperative. Operate properly,
as specied in this manual.
Never allow the machine to stand with an ink pouch removed. Remaining ink in the machine
may harden and clog the print heads.
The print heads are components that wear out. Periodic replacement is required, with the
frequency of replacement depending on use.
This machine becomes hot.
Never cover the ventilation holes with cloth, tape, or anything else.
Ink pouches
Ink pouches come in various types.
Use a type that is compatible with the machine.
Never subject to impact or attempt to disassemble.
Never drop or shake forcefully. The impact may rupture the internal pouch and cause the
ink to leak.
Never attempt to disassemble.
 Never attempt to rell the ink.
If ink gets on your hands or clothing, wash it off as soon as possible. Removal may become
difcult if you leave such adhered ink untreated.
Storage
 Store unopened in a well-ventilated location at a temperature of 5 to 30°C (-4 to 86°F).

Overview
Important Notes on Handling and Use
14
Warning labels are afxed to make areas of danger immediately clear. The meanings of these labels
are as follows. Be sure to heed their warnings. Also, never remove the labels or allow them to become
obscured.
Warning Labels
Caution: Moving Print Head Car-
riage
The print head carriage inside the
cover move at high speed and
pose a hazard. Never insert the
hand or ngers into the gap.
Caution: Pinching Hazard
Be careful not to allow the ngers
to become pinched when closing
covers.
Caution: High Voltage
Removing the cover may result in
high-voltage electric shock.
Caution: Moving Print Head Car-
riage
The print head carriage inside the
cover move at high speed and
pose a hazard. Never insert the
hand or ngers into the gap.
Ink, cleaning liquid, and discharged
uid are toxic
If these uids come into contact with
the eyes or skin, it may be hazardous
to the health. When performing mainte-
nance work, for example when dispos-
ing of discharged uid, wear protective
eyewear and protective gloves (refer to
the safety data sheet (SDS)).

Basic Operation
Preparing Media
Types of Media
In this manual, the paper used for printing is called “media”. There are the following main two media types
used in this machine.
Roll media: Media wound onto a paper tube
Sheet media: Media not wound onto a paper tube such as standard-size media
Various paper quality types of roll media and sheet media are selectable according your purpose. For detailed
information about each media, contact your media supplier.
Conditions for Usable Media
This machine cannot necessarily print every kind of media. When selecting media, be sure to carry out testing
in advance to make sure that satisfactory printing results are obtained.
Size
Width (*a) 259 to 1625 mm (10.2 to 64 inches)
Maximum media thick-
ness (*a)
1.0 mm
Roll outer diameter 210 mm
Paper tube (core) inner
diameter
76.2 mm (3 inches) or 50.8 mm (2 inches) (*b)
*a Applies to both roll and sheet media.
*bTo use 2-inch media, the optional media anges are required. For information about optional items, contact
your authorized dealer or us.
Maximum roll weight
40 kg (88 lb)
Note: If using the take-up system, this specication depends on the conditions of media that can be used
with the take-up system.
Other conditions
Media such as the following cannot be used.
Media whose end is attached to the paper tube (core)
Media which is severely warped or which has a strong tendency to reroll
Media whose paper tube (core) is bent or crushed
Media that bends under its own weight when loaded
Media on a sagging roll
Media that is rolled unevenly
Media Storage Environment
Depending on the type of transfer paper, if it is stored in a humid environment for a long time, the coating of
the paper may degrade and aect print quality. (In most cases, once the coating degrades, it will not return
to its original condition.) Avoid storing transfer paper in humid environments.
Read the precautions regarding your media carefully, and store it in an appropriate environment. For details,
contact your media supplier.

Procedure

Close the front cover.

Switch on the main power.

Switch on the sub power.
Sleep Mode (Power-saving Feature)
This machine is provided with a power-saving feature that switches to a low-power“sleep mode”when a xed
interval passes with no operation. The factory default for the time after which the machine switches to the
sleep mode is 30 minutes. When the machine is in the sleep mode, the sub power switch ashes slowly. Using
the operation panel or sending printing data from the computer restores the machine to its normal mode.
This setting of sleep mode can be changed. However, we recommend setting the activation time for the
sleep mode to 30 minutes or less to reduce power consumption and prevent problems such as overheating, .

Loading Media
Loading Roll Media
CAUTION Load roll media correctly.
Otherwise the media may fall and cause injury.
CAUTION Roll media weighs about 40 kg (88 lb). To avoid injury, handle with care.
CAUTION Do not load roll media that weighs more than 40 kg (88 lb).
The machine may fail to withstand the weight and tip over or cause the media
to fall.
1. Install the media on the media holder.
Note: The media holder of this machine is designed to be used exclusively with media that has a paper tube
(core) with an inner diameter of 3 inches. To use 2-inch media, the optional media anges are required.
For information about optional items, contact your authorized dealer or us.

Switch off the sub power.

Open the front cover.
Do not open the front cover until instructed to do so.
