[ 7 ] Envelope drawer
The envelope drawer is an option to allow a standard envelope to be fed from the drawer. Different side
walls compared to those of the current drawers are adopted. These side walls are positioned by being
aligned to the width of an envelope and they have the function of holding envelopes.
By using the drawer paper size detection sensors 1 and 2, the level where the envelope drawer is
installed is detected. Since the size of the paper in the envelope drawer is not detected automatically, it
is necessary to set it manually.
