Disconnect the power cable and wait at least 5 minutes
for capacitors to drain before disassembling the
POWER UNIT. If you touch the POWER UNIT with
the power supplied, you may receive an electric shock.
Do not touch the motors immediately after using the
printer, or you may burn your hand. Allow the motors
to cool enough to work with them.
To prevent the HCPP sensor cable insulation from
being damaged by the metal edge of the cable guide
notch on the HCPP SENSOR UNIT, pull the protective
tube up close to the HCPP sensor.
When installing the HCPP SENSOR UNIT, match the
positioning holes of the HCPP SENSOR UNIT to the
pins on the side frame.
