Vertical Format Units 5-6
DAVFU Line Slewing
Another method of moving paper using the DAVFU and PI line results in vertical slews of a
specified number of lines within the form, rather than slewing to a specific line. For this to ocĆ
cur, two criteria must be met:
1) PI line must be high
2) Data bit 5 must be 1 (set)
If these criteria are met, a specific number of lines will be slewed based on the status of data bits
1-4 as shown in Table 5-4. With bit 5 set and the PI line high, this type of vertical paper motion
will occur whether the DAVFU memory is loaded or not.
