Removing the Head Retainers and Installing

Lifting and carrying are operations that must be carried out by two persons, by grasping the bottom of the
machine. Failing to do so may result in injury.

Be sure to remove the head retainers before use. Failure to remove them may not only impede operation, but may cause
breakdown.
Do not attempt to touch any internal area other than the items described below, or to use excessive force to move any item.
Doing so may result in breakdown.

After you take the machine out of the carton, the
first thing you need to do is to remove the head
retainers. Carry out this operation before you
connect the AC adapter. When transporting the
machine, reattach the head retainers. Store the
head retainers in a safe place so that they do not
get lost.

1. Use the hexagonal wrench (3 mm) to

remove the three screws, then detach
head retainer 1.

2. Attach the three included caps.

3. Open the door. The blue panel visible to

the right of the table at the back is head
retainer 2. Use the hexagonal wrench
(2.5 mm) to remove the five screws, then
detach head retainer 2.

4. Remove head retainer 3, which is blue

and located at the top of the head unit.
Use the hexagonal wrench (3 mm) to
remove one screw, then pull head
retainer 3 up and out to extract it. Take
care not to drop the retainer when
extracting it.

Switching the Power On and Off and Opening and Closing the Door

Steps for Switching On the Power

There is a proper procedure for switching on the power to the machine. Follow the steps
below.

1. Close the door.

2. Press the Standby key .

3. The Movement LEDs flash. Keep the door closed until the flashing stops.
During this interval, the machine is performing initialization.

4. When initialization ends, the Standby key lights up green and the Move­ment LEDs go dark. Scanning is now possible.

Initialization may take up to about 40 seconds. If the door is opened during initialization, operation is interrupted to ensure safety.
In such cases, correct scanning cannot be performed. Switch off the power, close the door , then switch the power on again. Also,
sound that is differ from what you usually hear may be heard for several seconds during initialization, but this does not indicate
a malfunction.

Starting the computer after switching on the machine may make it impossible to perform scanning. This may occur depending
on the computer, but does not indicate a malfunction. If this happens, start the computer first, and then switch on the power to the
machine. Also, if the computer is restarted, reset the power to the machine as well.

Movement LEDs

Standby key

Switching Off the Power

When the machine will not be in use for a prolonged period, unplug the power cord from the electrical outlet.
Failure to do so may result in deterioration of the insulation, leading to electrical shock, short circuit, or fire.

Hold down the Standby key for 1 second or longer.

Opening and Closing the Door

When you open the door, the Standby key flashes green. Scanning cannot be performed while in this state. Close the door, then start
scanning.
To ensure safety, an emergency stop occurs when the door is opened while scanning is in progress. Scanning cannot be resumed even after
the door is closed.

If the Standby key does not flash when you open the door, the safety device may have failed. If this happens, immediately stop
use and contact your authorized Roland DG Corp. dealer or service center.
