The motor turns a worm gear. This gear pulls the wire that is attached to the
cleaner.
The wire cleaner first goes to home position (at the front, by the motor). Then
it moves to the rear (by the sensor), then to the home position again.
The corona wire is cleaned immediately after the main power switch or
operation power switch is switched on, if these two conditions occur:
The temperature of the hot roller is less than 50
˚C (122˚F).
600 m of paper fed through the machine since the last wire cleaning.
The 600-m interval can be changed with SP mode 2804.
The interval can be 300, 600, 900, 1200, or 1500 m. The
factory setting is 600 m.
To disable cleaning, set the SP to 0.
To enable cleaning immediately after every power-up, set the
SP to 1.
There is also a forced wire cleaning procedure - SP 2803. Do this when it is
necessary to clean the wire.
This SP also moves the cleaner to home position. Because of this, it is
important to use this SP after you change the motor or do some work
on the wire cleaning mechanism.
The actuator for the wire cleaner sensor turns while the cleaner moves. The
signals from this sensor tell the machine when the cleaning pad moves.
If the wire cleaner stops before it gets to the end, or if stops too long at
the far left position, the wire cleaner sensor detects an error.
The machine also uses this sensor to monitor the home position of the
cleaning pad.
