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.92 Setting the Interval until Activation of the Sleep Mode, P.92 Deactivating the Sleep Mode
When the machine is in the sleep mode, the POWER light flashes slowly. Using the control panel or performing
operations such as sending output data from the computer (when media is loaded) restore 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
How to Load Media
CAUTIONLoad roll media correctly.
Otherwise the media may fall and cause injury.
CAUTIONRoll media weighs about 30 kg (67 lb.). To avoid injury, handle with care.
CAUTIONNever load media that weights more than 30 kg (67 lb.).
The machine may fail to withstand the weight and tip over or cause the media to fall.
1.Load the media onto the roll shaft.
Open the front cover.
Move the media clamps to the sides.
Attach the media flanges to the roll media.
Place the roll media on the shafts.
Make sure the brake is engaged when you do this.

Pass the media between the pinch rollers and
the grit rollers, bringing the end of the media as
far as the platen.
2.Align the media.
Position so that both edges of the media are aligned above the grit rollers, and move the pinch
rollers to position them above the grit rollers.
Move the entire roll media to perform positioning.
The pinch rollers cannot be lowered at any position other than above the grit rollers. You can vary the number of
middle pinch roller used according to the width and composition of the media. Increasing the number used
makes media feed correspondingly more stable.
Grit roller Pinch rollerMedia
For the middle pinch rollers,
choose positions that are as
evenly spaced as possible
with respect to the width of
the media.
Position the left and right pinch rollers over
the edges of the media. Grit roller position
Symbols are present to serve as
guides for positioning the grit rollers.
Rear Be sure to place the right edge of the
media on these grit rollers.

Secure the stoppers in place in alignment with the width of the media.
The stoppers number four in total. Tighten all screws.
Important!
Make sure the media flanges are straight. Correct media feed is impossible if either of the media flanges is at an
angle.
3.Load the media so that it is without slack.
Pull out the media.
Hold the media at the center and pull it out, being
sure to keep it straight.
Make sure all areas of the media are taut.

Important Note When Using the Media Clamps
Insert the media clamps firmly all the way until they engage with an audible click, and make sure they will not come
loose. Incorrect mounting may cause the media to catch or snag and make correct printing impossible, or may lead to
malfunction or poor output quality.

Position the pinch rollers over the grit rollers.
If the following message appears when you close the front cover, open the front cover and check the positioning of the
pinch rollers. These must be placed over the grit rollers.
Placement of the Pinch Rollers
Position the pinch rollers at locations that are not overly close to the edges of the media.
Remove when not using roll media.
If roll media is allowed to stand unused in a loaded state for an extended period, the media may sag. This can cause
poor output quality and motor errors, so be sure to remove and properly store such media when not in use.

Procedure
Open the front cover.
Detach the media clamps.
Close the front cover.
Make sure the  lights up.
Hold down  for one second or longer.
Cut-off Operations
Before you perform cutoff, be sure to detach the media clamps. .
Performing cutoff with the media clamps remaining attached may cause the operation to be interrupted due to detec-
tion of the media clamps.
When youre performing cutoff, never use the  to pull the media back.
Unless the end of the media has been pulled out to a location to the front of the platen, cutoff may not be
performed smoothly.

2-3 Settings of the Media Heating System
What Is the Media Heating System?
This machine is equipped with a media heating system that warms the media. You use this mainly to improve ink
adhesion and dry the ink. You can adjust the temperature settings to match the type of media and the printing speed.
WARNINGCaution: high temperatures.
The platen and dryer become hot. Exercise caution to avoid fire or burns.
WARNINGRemove any loaded media or switch off the sub power when printing is not being
performed.
The continued application of heat at a single location may cause fire or produce toxic
gases.
WARNINGNever use media that cannot withstand the heat.
Doing so may result in fire or the release of toxic gases, or may degrade the media.
WARNINGNever use the platen or dryer for any purpose for which they are not intended,
such as to dry clothing.
Doing so may cause overheating, resulting in fire or accident.

General Guide for the Preset Temperatures
The optimal temperature for the media heating system varies according to such factors as the type of media and
differences in the print mode. Use the following as a general guide and adjust accordingly.
General Guide for Adjustment
Preheater
Set this to a temperature that is the same as or lower than the temperature of the print heater.
You use the preheater mainly to heat media gradually. This is because media becomes more likely to shrink or wrinkle
if heated suddenly.
Print heater
You use this mainly to improve ink adhesion and inhibit smudging.
If the ink forms lumps or smudges, raise the temperature. Note, however, that a temperature that is too high may
degrade the media or cause it to wrinkle.
Dryer
When ink drying is poor, raise the temperature. Note, however, that a temperature that is too high may degrade the
media or cause it to wrinkle.
The relationship between the print mode and temperature
If smudging or poor drying occur even after raising the temperature, try using a print mode offering higher image
quality. Conversely, when you want to use a faster print mode, raise the temperature.
Amount of ink
When you change the amount of ink using the settings for your software RIP, adjusting this may yield better results. If
problems such as smudging persist even after raising the temperature, try reducing the amount of ink.
Use at an ambient temperature of 20 to 32ºC (68 to 90ºF).
If the machine is used at an ambient temperature less than 20ºC (68ºF), then depending on the type or width of the
media, wrinkling or temperature-caused unevenness may occur. To obtain stable printing results the machine should
be used at an ambient temperature of 20 to 32ºC (68 to 90ºF).

Examples of Preset Temperatures
➢These are only rough estimates. Make adjustments to match the media youre using.
➢Using the media heating system does not necessarily make it possible to apply ink to every kind of media. Be
sure to test in advance.
➢Results may vary greatly depending on the print mode and other factors. Make settings suited to the media.
➢When suggested settings for temperature, print mode, and other values are given, use the suggested settings.
