c).
When attaching ESD brushes to the rear platen underside ensure even
pressure is applied to tape area. Press taped assembly into position for
approximately 30 seconds to ensure adequate bonding.
d).
Connect ground wire to a convenient earth return through the various screws
located on the underside of the platen chassis, refer to Figure A above.
CAUTION:
There is a serious safety issue when there is no earth ground
connected to the printer. The printer will basically function but can cause a safety
hazard if a person touches the printer chassis and another electrical device such
as a computer. The voltage on the chassis can be raised to a level of
approximately half the input AC voltage. The installer should always validate the
power and grounding scheme at the installation facility. A second issue would be
the lack of electrostatic discharge (ESD) protection. Without proper grounding the
ESD brushes are rendered useless. A higher incidence of cartridge failures will
occur if adequate grounding not properly supplied as well as possible
malfunctions of printer’s electronic circuitry.
e).
This completes the field installation kit procedure.
