Caution - MUTOH Rockhopper II series Maintenance Manual

1.3.2. Caution

Assembling and disassembling the printer are possible only for the parts shown in the operation manual.
Do not disassemble any frame parts or parts of which disassembling procedures are not shown in the
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 down the transparent film on the sides of the damper assembly with your hands. The
damper assembly is filled with ink and pressing on the film will make the ink spurt out.
Be careful not to scratch the transparent film on the sides of the damper assembly.
Be careful not to touch the surface of the print head's nozzles or to let dirt adhere to them.
There is some remaining ink in the tubes. Be careful that the ink is not spilled from the tube onto the
printer or objects 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 moving parts.
Do not oil the printer mechanism with oil other than the oil designated by MUTOH. Doing so may
damage the parts or shorten the lifetime.
If the power substrate assembly needs to be removed, disconnect the power cable and wait for at least 5
minutes before taking it out. This will discharge the residual electrical charge of the electrolytic capacitor.
Touching the substrate before the capacitor discharges may cause electric shock.
When connecting or disconnecting the FFC type cable from the connector of the main substrate
assembly, be sure to connect or disconnect the cable straight out from the connector. Connecting or
disconnecting at a slant angle may damage, break or short-circuit the inner terminal of the connector.
That may damage the elements on the substrate.
When connecting or disconnecting the FFC type cable from the connector of the CR substrate, be sure
to connect or disconnect the cable straight out from the connector. Connecting or disconnecting at a
slant angle may damage, break or short-circuit the inner terminal of the connector. That may damage
the elements on the substrate.
Before replacing parts, be sure to adjust the capping position. When the capping position adjustment
has not been implemented, the cleaning position and other operational positions can exit the alignment
and normal operations become impossible.
Pay attention to the following points when performing the cutter endurance operation.
 I nstall an available ink cartridge.
 M ake sure that media initialization has been completed.
Make sure that the power of the printer is OFF before performing the parameter backup. Performing the
parameter backup with the power ON may damage the main substrate or data may not be properly
installed.
Make sure that the power of the printer is OFF before installing the firmware. Installing the firmware with
the power ON may damage the main substrate assembly or data may not be properly installed.
Ensure there is sufficient space around the printer when performing maintenance work.
Maintenance must be done by more than one person for :
detaching the printer from the stand or attaching it.
packing the printer for transportation.
Be sure to directly clean when spoiling RH Cleaning Liquid. Because this liquid could damage the paint.
