Relative Line Slewing
Like the DAVFU, the PI line can be used to slew a specified number of lines rather than
slewing to a specific line. To accomplish this, three criteria must be met:
1.
The PI line must be enabled and set high;
2.
Data bit 5 must be enabled and set high;
3.
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 5-6. (Note that state of data bit 5 is the difference be
tween line slewing and using 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.
NOTE: When using Relative Line Slewing with Elongated (Double High)
print, the paper will be moved n + 1 lines rather than n lines.
