Moving the lever to its highest position disengages the
separator. This position is used for the improved feeding
of heavy cardstocks.
Tray Pressure
Increasing the tray pressure gives the feed wheels greater
force on the paper; too much will result in double feeds
and increases the possibility of scuffing the paper.
The ideal pressure will depend upon the stock in use.
Always use the least pressure possible. The lever has five
positions and is adjusted by gently pushing downwards
whilst sliding the lever in or out. The innermost position
gives minimum pressure. Initially set the pressure to
minimum for small stock. For large sheets (i.e. if tray
extenders are used) initially position the lever one notch
out.
Air Separation
Air directed from the right hand sidelay is used to separate
the top sheets of paper in the stack. The overall air level
is adjusted if required by altering the
AIR BLOW
value, in
the
BASIC
window (see p.14). The air level is also adjust-
able on each individual bin via a tap on the right hand
sidelay.
The tap on the sidelay controls the air level into the side
of the paper stack. The tap has three positions. The default
position is 90° to the sidelay which provides 100% air.
Moving the lever one notch towards you provides 50%
