Vertical Format Units 5–6
Relative Line Slewing
Another method of moving paper using the PI line results in vertical slews of a specified number 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:
•
The PI line must be enabled and set high;
•
Data bit 5 must be 1 (set); and
•
The EVFU must be the selected Vertical Format Unit.
The Slew Relative configuration and the status of data bits 1–4 determine the number of lines slewed as
described in Table 5–3. (Note that the state of data bit 5 is the difference between line slewing and us-
ing the interface lines as EVFU channel codes.) As long as the EVFU is selected, this type of vertical
paper motion will occur, regardless of whether the EVFU memory is loaded or not.
If the Double High for One Line attribute is active, n + 1 lines are slewed rather than n lines.
