3.2 Low Handler Sensor Adjustment

1. Remove the cover.
2. Check the high handler bar sensor can move freely. If not, unscrew the M4 screw that fixes
the bar slightly (see "1", Figure 3).
3. Check the bar is aligned to the sensor OPT1, on the bottom of the electronic board. If not,
gently bend the bar to realign it.
4. Check the bar hook doesn't touch the drawer, and that the distance from the hook and
the bottom bar of the drawer is less than 1mm (see "2", Figure 3). If not, alter the
distance using the M3 screw and lock it with the M3 nut (see "3", Figure 3).

5. Disconnect the motor cable from the electronic board (2 poles connector J3)
6. Close the drawer completely and manually lift up the platen (rotate the motor manually)
until the hook completely blocks the drawer. Check the drawer can move by
approximately 1 mm by pushing it (see Figure 4). If not, unscrew the two screws that fix
the L-bar to the drawer, and re-position it. Re-tighten the two screws (see Figure 5). If
necessary, gently bend the L-bar.
7. Reconnect the motor cable.
