EEPING THE FAX MACHINE IN GOOD WORKING ORDER
CLEANING THE OPTICAL READER
Dust accumulating on the glass of the optical reader
can cause problems in reading documents. To pre-
vent this problem, you should clean the glass every
so often as follows:
1.
Disconnect the machine from the electrical
power supply.
2.
Push in the lever situated under the right hand
side of the operator panel and lift the panel.
3.
Holding up the panel, clean the optical reader
glass using a cloth dampened with a product
specifically for cleaning glass, and then dry care-
fully.
Do not pour or spray the cleaning agent di-
rectly on to the glass.
4.
Close the operator panel.
5.
Reconnect the machine to the electrical power
supply.
To check that the optical reader is clean, make a
copy of a blank page. If vertical lines appear on the
copy and further inspection of the optical reader
shows it to be perfectly clean, contact a qualified
technician.
