2.3 Learn Mode
This key places the counter in learn mode. Learn mode can
only be activated if the folder is idle.
The learn mode allows the user to setup the suction valve
controller. Both manual and automatic setup is accom-
plished in this mode. The large display (1) shows two
separate data items. On the left is the suction mode and the
right shows sheet length. The small display (2) shows the
current gap length. The suction length display is active.
During Learn Mode, the Learn Mode key LED indicates
whether a valid sheet has been learned. See table 15.
Table 10. Learn Mode Status
When the LED is on, pushing the sheet start button will
feed a single sheet of paper. If the sheet is fed properly, the
indicator LED will go off. The suction mode will be set to
automatic. The length of the sheet will be set as the current
sheet length. The suction length will be set based on table 9
and the gap length will be set to 1.5 inches/4 cm if P06 is
set to 0 (no knife is active); the gap length will be 4.0
inches/10 cm if P06 is set to 1 (knifes are active).
Gap Length Adjustment
The minus and plus keys adjust the gap length. The gap
length range is 0.2” to 98.0” (0.5cm to 250cm).
Suction Length Adjustment
The suction length adjustment keys allow the user to
change the amount of suction applied to the current sheet
length. The display shows the percentage in 5% steps. All
of the bars must be totaled to get the value. The range of
adjustment is 5% to 50% of the current sheet length. If the
suction length is manually adjusted while the Learn Mode
LED is on, the suction length will no longer be the Single
Sheet suction length of 6.0 inches. The new suction length
will be based on the current sheet length and suction
setting.

Select Suction Mode
These keys toggle between automatic control and cycle
mode. In the cycle mode, the suction valve will be on for
the suction length and off for the remainder of the sheet
length plus the gap length. No adjustments are made for
slipped sheets or process changes. The automatic mode
corrects for process changes and controls the timing of the
suction valve to maintain the user selected gap. If the gap is
less than 2” (50 mm), the right hand decimal point of the
small display (2) will flash and the Leading edge control
will be active. If the gap is greater than or equal to 2.0” (50
mm), full Leading and Trailing edge control is maintained.
Refer to table 8 for suction mode symbol definitions.

Sheet Length Adjustment
The sheet length adjustment keys allow the user to
override the automatic Learn Mode. When the user
changes the sheet length, the suction length will be
adjusted according to table 9. If a different suction length
is desired, the value may be overridden with the suction
length adjustment keys. The sheet length range is 4
inches/10 cm to 98.5 inches/250 cm.
