MBM Corporation CREASEMATIC AUTO 50 - Manual (Page 28)

Auto 50 problem solving:
1. ‘Knife error’ or ‘stop’ showing on screen.
1.1. Machine jamming with card
1.2. Knife out of position.
Try a different matrix tool
1.3. Knife pulley loose on motor shaft
2. Knife does not always cycle or behaves erratically:
2.1. Ensure knife flag is aligned with and passes through the slotted photocell.
2.2. With age and use the knife may over run at the end of cycle. Ensure that at the
end of cycle the flag is still obscuring the slotted photocell.
2.3. Check output from photocell. Place positive probe (red) of meter (set to 24v DC
range) on orange at local terminal strip and place other probe (black) on pin 29
(white/red wire) of the green IDC connector. When the photocell beam is broken
(knife flag) the meter should read 5volts, other wise 0volts should be shown.
2.4. Check and change as necessary R4, the knife motor run relay.
2.5. Knife pulley loose on motor shaft
3. Paper feeds through machine without being creased:
3.1. Ensure a crease position is set.
3.2. Check output from photocell. Place positive probe (red) of meter (set to 24v DC
range) on orange at local terminal strip and place other probe (black) on pin 31
(white/blue wire) of the green IDC connector. When the photocell beam is
broken (paper present) the meter should read 5volts, other wise 0volts should be
shown.
4. Feed motor does not run:
4.1. Ensure cover is closed (white/brown wire).
4.2. Ensure catch tray is properly attached.
4.3. Ensure main (large 11 pin relay) is actuated. Contacts are in up position.
4.4. Ensure motor inverter shows green LED (enabled). If LED is red, motor is not
enabled.
