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 informa-
tion on the SFCC.

Clearing the EVFU Memory

Following one of these actions resets (clears) the EVFU memory.
Sending only the start load code.
Sending a start load code followed immediately by an end load code.
Sending a second start load code, which reinitializes the EVFU. (This restarts the host
data.)
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.
