The drive signal waveform generated when the drawer is driven according to the above conditions
is shown in Figure F-1.
OFF
ON
t1 × 2ms t2 ≥ (t1 × 4) × 2 ms
Figure F-1 Drawer Drive Signal Waveform (Formulas F-1 and F-2)
The ON time depends on the specifications of the drawer used. Be sure to check the drawer
specifications and set a suitable time. To use a drawer that does not meet the conditions of
Formulas F-1 and F-2, see the following section.
3) Using a drawer that does not meet the conditions in 2) (ESC p, DLE DC4)
i. For ESC p
Setting the values of t1 and t2 according to the conditions in 2) results in a maximum ON time of
126 ms (0 ≤ t1 ≤ 63), since the setting ranges of t1 and t2 are 0 to 255. To use a drawer that
requires an ON time exceeding 126 ms, the following conditions must be met:
ON time
ON time + (OFF time + α)
≤ 0.2.................................Formula F-3
α:other sequence processing time
NOTE: α is the drawer-driving prohibited period from the OFF time until the next ON time.
ii. For DLE DC4
Since DLE DC4 sets ON time equals to OFF time, use α so that Formula F-3 is met.
