Maximum insert specifications are based
on single sheets. When multiples are
handled, more room inside the envelope is
needed depending on the application.
In general more space between the set
width and the envelope width will improve
the performance of the system.
The specification of the paper handling
equipment is often wider than that of the
envelopes and documents handled.
We recommend that materials to be
handled are stored at a temperature of 20°C
(68°F) with a relative humidity factor of 50%.
If difference in temperature occurs between
store room and mailing area, the material
has to be stored near the system at least
24 hours before use.
