CAUTION
• Assembling and disassembling of the plotter are possible only for the parts that
disassembling procedures are shown in this manual. Do not disassemble any frame parts
or parts that disassembling procedures are not shown in this manual.
Doing so may cause trouble that cannot be restored, as the plotter is originally assembled
in the factory with a high accuracy of 1/100 mm.
• Do not touch the elements on the circuit board with bare hands.
Doing so may cause static electricity and break the elements.
• Do not press the transparent film on the damper assembly with your hands. Doing so may
discharge the ink filled inside the damper assembly.
• Be careful not to damage the transparent film on the damper assembly.
• Do not touch the nozzles of the print head. Make sure that the nozzles do not get any dust.
• There are some remaining ink in the tubes. Be careful that the ink is not spilled from the
tube outlet onto the plotter or items close to the plotter.
• If you need to operate the plotter with the cover removed for maintenance, be careful not
to get hurt by the driving parts.
• Never lube the plotter mechanism with lube other than that designated by MUTOH. Doing
so may damage the parts or shorten the lifetime.
• If the power board assembly needs to be removed, remove the power cable and wait for
5 minutes or more before taking it out; this will discharge the residual electrical charge of
the electrolytic capacitor.
Touching the board before the capacitor discharges may cause electric shock.
• When connecting or removing an FFC type cable on a main board assembly connector,
make sure to connect or remove the cable perpendicular to the connector.
Connecting or removing at a slant angle may damage, break or shortcircuit the inner
terminal of the connector. That may damage the elements on the board.
• When connecting or removing an FFC type cable on the CR board assembly connector,
make sure to connect or remove the cable perpendicular to the connector.
Connecting or removing at a slant angle may damage, break or shortcircuit the inner
terminal of the connector. That may damage the elements on the board.
• Make sure the followings when performing cutter endurance operation.
• Install usable ink cartridges.
• Make sure media initialization is finished.
Performing cutter endurance operation without an ink cartridge may make the cutter go
down beyond the cutting range and damage the product.
• Make sure the power of the plotter is OFF before performing the parameter backup.
Performing the parameter backup with the power ON may damage the main board or the
data may not be installed properly.
• Make sure the power of the plotter is OFF before installing the firmware. Installing the
firmware with the power ON may damage the main board assembly or the data may not
be properly installed.
