The ESC pm t1 t2 commands select either Drawer Kick-out Signal 1 or 2 to set the pulse time.

T1 x 2ms When ON

T2 x 2ms When OFF

Note:

•T2 (when OFF) ≥ T1 (when ON) Ω4 is satisfied.

•The maximum amperage at +24V is up to 1A. When connected to one that exceeds 1A, the printer and connected equipment may be damaged.
