5.4.1 Replacing the prefilter
The prefilter bag must be changed after every 10,000 - 15,000 cassettes - de-
pending on the type of laser printing (positive or inverted) - or 1x a year.
If the laser printer detects a reduction of the air flow rate, an audible signal is
sounded by the filter unit and you see the following message on the monitor.
When either condition (warning or beeping) is present the user must
change the prefilter bag.
Fig. 28
In the case of the warning, click OK on the warning massage window after
you have changed the filter to reset the counter back to zero. If you click the
Cancel button, the window is closed, but the window reappears after the
next cassette is printed.
In the case of the beeping, changing the prefilter bag should stop the beeping.
If this is not the case, contact your Leica service technician!
