Replacing the Verification Stamp
If you are using the Verification Stamp function, you will need to replace the
ink cartridge in the stamp unit when it runs out of ink (when the stamped mark
on original documents becomes faint). A new ink cartridge can be obtained
from your dealer.
1
Remove the ADF exit tray.
2
Press down on the protruding tab of
the green ink cartridge and pull the
cartridge out with your fingers.
3
Insert the new ink cartridge into the
machine (make sure that the tab is
facing out).
