MX-FN11 OPERATIONAL DESCRIPTION 4 – 13
a)
A hole is punched along the trailing edge of the 1st sheet.
While two holes are being made, the 3-hole puncher
makes a single round trip in escape direction (moving up
the hole puncher).

b)
Holes are made along the trailing edge of the 2nd sheet.

(4) Horizontal registration operation
The horizontal registration drive for the punch slide unit is provided
by the horizontal registration motor (FPSM). The home position of
the punch slide unit is detected by the horizontal registration home
position sensor (FPSHPD). The punch slide unit detects the trailing
edge of sheets using the trailing edge sensor (LED5, PT5) and the
horizontal registration sensors (LED1 through 4, SREG1 through
4), and causes a move to a specific position matching the trailing
edge of each sheet (in relation to the size of the sheet).
The horizontal registration operation takes place as follows:
1)

the punch slide unit is detected by the horizontal registration home
position sensor (FPSHPD). The punch slide unit detects the trailing
edge of sheets using the trailing edge sensor (LED5, PT5) and the
horizontal registration sensors (LED1 through 4, SREG1 through
4), and causes a move to a specific position matching the trailing
edge of each sheet (in relation to the size of the sheet).
The horizontal registration operation takes place as follows:
1)
When the leading edge of a sheet from the host machine is
detected by the trailing edge sensor (LED5, PT5), the horizon-
tal registration motor (FPSM) starts to move the punch slide
unit toward the front.

unit toward the front.
2)
When the horizontal registration sensor (LED1 through 4, PT1
through 4) suited to the paper size signal from the host
machine detects the rear edge of the sheet, the horizontal reg-
istration motor (FPSM) causes a further move to a specific
position, and stops the punch slide unit.
