Adjust the envelope separation by turning knob D counter
clockwise until two envelopes (flap down and trailing), one
on top of the other, can be moved backwards and forwards
between the rollers without resistance.
The turn knob D clockwise until one envelope will pass
between the rollers.
After starting the machine it may occur that more than one
envelope at a time is pulled in. If this happens, rotate knob
D clockwise a quarter turn. Repeat if necessary to obtain
correct operation.
Once the envelope separation has been set, a wide variety
of envelopes can be handled.

4.8.1 Envelope separation
Fig. 17
4.8.2 Side guides
Take a stack of about 20 envelopes. Fan the envelopes a
bit (see fig. 18) and place the envelopes in the hopper with
the flap down and “trailing” on the envelope support B
(fig.17).
The bottom envelope must enter the separator first. Adjust
the side guides C (fig.17) by turning the thumbwheel A
(fig.17) to provide enough space to move freely. Too much
play causes skewing.
4.8.3 Envelope support
Adjust the envelope support B (fig.17) so that the flap side
of the envelope is lifted about 20 mm (0.8 inch).
Envelopes may skew on the insert table. The envelope
support B can be rotated slightly to compensate this. Turn
the envelope support B so that the weight of the envelopes
is distributed evenly on both sides.
Top up the envelope hopper with more envelopes.

4.8.4 Envelope receiving tray
The SI 72 has a rear envelope receiving tray A (see fig.19)
this can be adjusted according to the envelope height, by
shifting it in or out.
