Verification Stamp option (FO-45VS)
Note: This feature is available as an option. Consult your dealer if
you wish to use this feature.
When transmitting a document, you can have the fax machine stamp
each document page as it is scanned. After scanning, you can check
to see if all document have been stamped to verify that no double
feeds occurred. (A double feed occurs when two pages are fed through
the scanner at once, which means that one of the pages is not
scanned.)
To use this function, have your dealer install the Verification Stamp
option, and then set Option Setting 29 to ON.

Press the cover release to open the print compartment cover.
•
Caution! The fusing unit inside the print compartment becomes
very hot during operation. Be careful not to touch the
inside of the compartment.

If you are replacing the toner cartridge, remove the old cartridge and
dispose of it according to local regulations.
Go directly to STEP 5 if you are only replacing the toner cartridge
and not the drum cartridge.
•
If you are replacing the drum cartridge but not the toner cartridge,
remove the toner cartridge and place it on a sheet of paper.
To make the cartridge more compact for disposal, press the buttons on
the ends of the handle and fold the handle down.

If you are replacing the drum cartridge, remove the old cartridge and
dispose of it according to local regulations.

Remove the new drum cartridge from its packaging. Insert the drum
cartridge into the print compartment.
•
Caution! Excessive exposure to light will damage the drum
cartridge. Install the cartridge promptly after removing it
from its packaging.
•
Make sure the drum cartridge is inserted in as far as it will go.

If you are installing a new toner cartridge, remove the new toner car-
tridge from its packaging. Remove the tape from the cartridge and
then open the cartridge handle so that it stands straight up.
6
Shake as indicated by the arrows to distribute the toner evenly within
the cartridge.
•
If the toner is still lumpy after shaking, the gears in the cartridge
may make a noticeable sound when the print compartment cover
is closed after installing the cartridge. This is normal and does not
indicate a problem.
