2) Notes on using the specified pulse generation command (ESC
p)
When the drawer is connected to the drawer kick-out connector and
driven using the specified pulse generation command (ESC P), specify
the parameters n1 and n2 in this command so that they will meet the
following conditions.
ON time
ON time + OFF time
0.2
(Formula D-1)
or OFF time ON timeX4
(Formula D-2)
When the drawer is driven in accordance with the conditions above, the
signal waveform of the drive signal is as shown in Figure D-l .
ON
OFF
n1X2 ms
n2 (n1X4)X2 ms
Figure D-l . Drawer Drive Signal Waveform
Because ON time differs depending on the drawer used, set the ON time
according to the drawer specifications. However, drawers which do not
meet formulas D-l and D-2 cannot be used.
3) Notes on using the drawers that do not satisfy the conditions described
in 2). When the values of n1 and n2 are determined according to the
conditions described in 2), the setting value range of n1 is 0 to 255 and
the n1 value range inevitably becomes 0 n1 63, and the maximum
ON time is 126 ms. If the drawer needs more than 126 ms ON time, set
the ON time and OFF time so that they can satisfy Formula D-3.
ON time
ON time + (OFF time + α)

NOTE: α means the drawer driving prohibited period from the end of
OFF time to the start of ON.
