1. Getting Started
This section describes the features, part names, and the like of the HU-
740/640/540.

Chapter 1: Installation
1-1 What's the HU-740/640/540?
Features
The HU-740/640/540 is a heater unit for Roland DG SOLJET ProII series large-format printers. It enhances the fixation
of the ink on the media and dries ink faster by preheating the media before printing. The controller for the HU-740/640/
540 allows you to adjust the heater temperature to match the media.
Installable Combinations
The HU-740/640/540 can be installed on the following printers.
HU-740 ... SJ-740
HU-640 ... SJ-640
HU-540 ... SJ-540/SC-540
In this manual, the HU-740/640/540 is referred to as the "heater unit," and each model of the printer is referred to as the
"printer."
Recommended Ink
Use ECO-SOL INK to ensure acceptable printing results when performing printing while using the heater unit.
Using inks other than ECO-SOL INK may cause unexpected printing results.

Chapter 1: Installation
1-2 Installation and Transport
Installing the Heater Unit on the Printer
The heater unit is to be installed on the printer by an authorized service engineer.
About the Power Supply
Be sure to use an electrical outlet for the power supply. Also, do not connect multiple electrical loads on a single
electrical outlet.
Low or unstable voltage may result in inadequate heater performance. If the temperature of the heater fails to rise
adequately even when used correctly, check the voltage of the power supply.
When Moving the Printer
Cables for the heater unit are located under the bottom of the printer. When removing the printer from the stand in order
to move the printer to a different location, take care not to damage these cables. Otherwise fire, electric shock, or other
serious damage may occur. In addition, the printer that the heater unit has been installed on cannot be repacked. In the
event of damage to the cables or when repacking the printer, please contact your authorized Roland DG Corp. dealer or
service center.
Never attempt to install the heater unit on the printer by yourself.

Switching Off the Controller
Switch off the [POWER] switch on the controller.
Power Source for the Heater
The heater is connected to the sub power for the printer.
The heater operates only when both the controller and the sub power for printer are switched on.
When the display shows characters other than numerical figures, such as UUUU or LLLL, immediately switch off the control-
ler and contact your authorized Roland DG Corp. dealer or service center.
Switch off the controller when not using the heater.
The preset temperature of the heater is saved in memory when the controller is switched off.
2-1 Switching the Power On and Off
When not in use for extended periods, unplug the power-cord plug from the electrical outlet.

2. Using the Heater Unit
2-2 Loading Media
About the Ambient Temperature During Heater Use
To ensure stable printing quality, we recommend use in an environment where the ambient temperature is 20˚C (68˚F)
or higher.
At low temperatures, warm-up may take a long time, or the temperature may fail to reach the preset value, or large
differences in temperature may occur. Inadequate temperature may result in coarse printing.
If the media fails to warm up sufficiently, try setting the heater to a higher temperature. If this fails to resolve the
problem, raise the temperature of the room.
Points to Observe When Loading Media
Check and observe the following points when loading media. For detailed information on how to load media, refer to
the user's manual for the printer.
Use Media With a Width of about 1 m (40 in.) or More
We recommend using media having a width of about 1 m (40 in.) or more. Media of narrower width may take a long
time to heat, or may fail to reach the preset temperature.
Also, in no event should media having a width of 50 cm (19-11/16 in.) or less be used. Doing so may lead to danger of
overheating.
Before Loading Media, Allow the Heater to Cool Down to 30˚C (86˚F) or Lower
Before loading media, switch off the controller or set the preset temperature to 30˚C and allow the heater to cool down.
Loading media when the heater is 30˚C (86˚F) or more may cause the media to wrinkle or warp due to the sudden rise
in temperature.
When Printing, Use the Media Clamps
Set the height of the printing heads to either "Middle" or "High," then engage the media clamps. Depending on the
media, the edges of the media may warp due to heat or the media may strike the printing heads, causing jams or
malfunction.

18
2. Using the Heater Unit
2-3 Printing and Cutting
Printing
Before performing printing, set the preset temperature to 40˚C (104˚F) and wait until media becomes sufficiently warm.
For information on how to perform printing, refer to the user's manual for the printer.
1
After loading media, set [SV] on the controller to 40˚C.
It may take from few minutes to approximately 30 minutes to reach the
preset temperature, depending on the ambient temperature.
2
To heat the media sufficiently, wait for five minutes after
making sure that the [PV] on the controller reaches 40˚C.
Then perform printing.
The recommended ambient temperature for ensuring acceptable quality when performing printing is 20 to 32˚C (68 to 89.6˚F).
When the ambient temperature is less than 20˚C, the media doesn't heat up enough to ensure acceptable quality. In such cases,
set the preset temperature to higher value.
The setting range of preset temperature by the controller is 30 to 50˚C ( 86 to 122˚F).
Performing printing as soon as the heater temperature reaches 40˚C may result in coarse printing because the media is not warm
enough.
When the heater reaches the preset temperature, the [C1] indicator goes dark and the heater stops operating. The heater is
switched on and off automatically to maintain the preset temperature. Meanwhile the [C1] indicator lights up and goes dark to
indicate the status of the heater.
