Vertical Format Units 5-10
Start Load - Clears and initializes the EVFU memory for the memory load program. The
Start Load code is 1E hex when the PI line is not used or 6E hex when the PI line is used.
End Load - Terminates the memory load program. The End Load code is 1F hex when the PI
line is not used or 6F hex when the PI line is used.
Channel 1 - The top-of-form code, reserved as the first line on the form or the first line
printed (top-of-form position). The operating program sends the channel 1 code to advance
to the top of the next form.
Channels 2 through 11, 13 and 14 - Used as general channel codes, line identification codes,
or filler channels. Each line on the form must be identified by a channel code. When the operatĆ
ing program sends the channel code, the paper advances to the line identified by the channel
code. Filler channels are used to identify lines that will never be accessed by the operating proĆ
gram.
Channel 12 - Reserved as the Vertical Tab channel. The Vertical Tab code (VT, 0B hex) prints
any data in the print buffer and rapidly slews the paper to the next line identified by the channel
12 code. If channel 12 is not loaded in the EVFU memory, a single line feed will be executed
when a VT code is sent.
Form Feed - A Form Feed code (0C hex) advances the paper to the next top-of-form posiĆ
tion.
P-Series EVFU Form Definition Program
The P-Series EVFU form definition program (memory load program) is sent to the printer
from the host computer to assign channel codes to the lines of a form. The channel codes are
later accessed by the operating program to print specific data at the lines identified by the
codes. A sample EVFU form definition program is shown in Figure 5-2.
