General Maintenance Issues
.
When performing service and maintenance operations,
sufficient space should be assured surrounding the place where
the work is performed.
The printer should be set in a place where there is no vibration,
and where it is level and stable.
This machine is extremely heavy (the body only weighs
approximately 43.5 kg / The body + the stand weighs
approximately 52 kg), so adequate caution should be exercised
when handling it. (If you are taking or reinstalling the body and
stand, there should be 2 or more persons doing the work.)
If operations are performed which involve the removal of ink
system parts, there is danger of the product or the floor, etc. in
the place where it is installed becoming soiled, so sheets, etc.
should be spread on the floor, etc. during the work o removing
parts related to the ink channels.
If you are handling electrical circuit boards, to prevent
destruction of the elements by static electricity, the elements on
the board should not be touched with bare hands. If necessary,
take the necessary measures to prevent static discharge, such as
wearing a ground strap, when performing such work.
If you are removing the various covers and operating the printer
in that state, adequate caution should be used so as not to be
injured by high speed operating parts such as the PS fan.
The cutter blade is extremely sharp, care should be taken not to
be injured by it.
The an ultra-hardened blade is used for the cutter blade, and
materially, this item is extremely brittle, so it should not be
bumped against any metal or other parts on the printer when
handled.
If the printer needs to be transported for any reason, refer to
Chapter 9 of the Users Guide to put the printer into printer-
transport mode. Also, only use original packing materials and
pack the printer as shown in the Start-Up Guide or Assembly and
Setup Guide.
