1.3 Important Safety Instructions
General safety instructions that must be observed to use the equipment safely are explained below.
WARNING
Do not place the printer in the following areas. Doing so may result in the printer
tipping or falling over and causing injury.
• Unstable surfaces
• Angled place
• Areas subject to vibration by other equipment
Do not stand on or place heavy objects on your printer. Doing so may result in the
printer tipping or falling over and causing injury.
Doing so could obstruct ventilation and cause fire.
Do not cover the ventilation hole of your printer with cloth, such as a blanket or table
cloth.Doing so may result in fire.
Do not place the printer in humid and dusty areas. Doing so may result in electrical
shock or fire.
Make sure to use the power cable packed with the printer you purchased. Not doing
so may result in electrical shock or fire.
Make sure that the following is performed before parts replacement.
• Turn off the power of the printer.
• Remove the power cable from the power outlet.
Not doing so may cause electric shock or damage to the electric circuit.
• Unplug the cables connected to the printer.
Failure to do so could result in damage to the printer.

CAUTION
Assembling and disassembling of the printer 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 printer 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.
Never lube the printer mechanism with lube other than that designated by MUTOH.
Doing so may damage the parts or shorten the lifetime.
There are some remaining ink in the tubes. Be careful that the ink is not spilled from the
tube outlet onto the printer or items close to the printer.
If you need to operate the printer with the cover removed for maintenance, be careful
not to get hurt by the driving parts.
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 short circuit 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 short circuit the inner
terminal of the connector. That may damage the elements on the board.
Make sure there is sufficient space around the printer when performing maintenance
work.
Maintenance must be done by more than two person for the following work.
• When disassembling or reassembling the product and the optional stand
• When packing the printer for transportation
