NOTE: The ESC code cannot be used simultaneously as the EVFU VT code and the Special Function Control Character (SFCC). If ESC is used as the SFCC, the EVFU must be used with the PI line enabled and set high. Refer to the Configuration chapter for more information on the SFCC.

Clearing the EVFU Memory

The following actions will reset (clear) the EVFU memory:

1.Sending only the start load code.

2.Sending a start load code followed immediately by an end load code.

3.A second start load code is received, resulting in reinitialization of the EVFU. (This alF lows the host data to be restarted.)

When the EVFU memory is cleared, the forms length returns to the previously set value and the current print position becomes the top-of-form (TOF).

Relative Line Slewing

Another method of moving paper using the PI line results in vertical slews of a specified numF ber of lines within the form relative to the current print line (rather than slewing to a specific line). For this to occur, three criteria must be met:
