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	≤ 0.2	Formula F-3
	ON time + (OFF time + α)

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.
