Replacing the Stamp Cartridge
Originals can be stamped to indicate that they have been sent. Replace the stamp 
cartridge when this mark is faint or no longer visible.
When replacing the stamp cartridge, take care not to allow ink to come in contact with your hands or clothing. If 
ink gets onto your hands or clothing, wash it off immediately with cold water.

Open the feeder cover, then open 
the inner cover (B) by holding its 
front tab for removing the old 
stamp cartridge (A).

Remove the old stamp cartridge 
using the tweezers.
Widen the tweezers if necessary.

Insert a new stamp cartridge into 
the feeder using the tweezers until 
it clicks.
Set the stamp cartridge so that the two 
projections on the cartridge are aligned 
with the hollows on the feeder.
Be careful that the stamping surface of the 
stamp cartridge does not protrude.
Insert the stamp cartridge properly, or it 
may cause paper jams.
