ELECTRONIC VERTICAL FORMAT UNIT - EVFU

Downline vertical tab loading is accomplished through the EVFU. The EVFU allows loading a form table with a minimum form length of

.33 inches (240 decipoints) and a maximum length of 24 inches (17,280 decipoints).

Since the maximum length is 24 inches, the number of lines is dependent on the lpi setting. 3 lpi = 72 lines. 4 lpi = 96 lines.

6 lpi = 144 lines, and 8 lpi = 192 lines. Exceeding the maximum causes a fault.

Downloading the EVFU

▪The vertical format type must be set to VtType:Emul VFU through the control panel using the Program Mode.

▪No paper instruction lead (PI) is required.

▪When the printer has an EVFU table loaded, VFU is displayed on the control panel.

ESC ] !Start EVFU table loading sequence. Each line of the form requires an entry. Dummy values (filler codes - See Table of Channel Codes on page 5-30) are required in lines with no channel. Two bytes are required for each line of the form. Loading Is terminated by the ESC \ sequence.

Decimal:

27 93 33

Hex:

BASIC:

CHR$(27);"]!";

Loading the Table

The first table location is normally loaded with the channel 1 code. This is defined as the top-of-form (TOF) channel. The table may be left without channel 1, and a command to skip to channel 1 will cause a normal form feed as though there were no VFU. Two bytes are loaded for each line of the form to be controlled. One or more channel numbers may be indicated in the two-byte code.

The format of two-byte channel control code is:
