(cc)NORMAL The Normal mode command. If the form count
parameter was not used in the Execute command,
enter the SFCC and NORMAL to return the IGP to
the Normal mode. The Normal mode command is
input following all other Execute commands to
enter variable data. (Refer to the following
sections.) Input a line terminator to leave a blank
line before entering the Normal command.
Execute Form: Electronic Vertical Format Unit
Purpose Provides an efficient method of rapidly slewing paper.
Mode EXECUTE
Format See Appendix C
.
Comments The Electronic Vertical Format Unit (EVFU) is processed as
overlay data within the Execute Form mode. Detailed EVFU
information is provided in Appendix C.
The EVFU must be loaded while in the Execute Form mode and immediately
following the Execute command. After executing the form and returning to
Normal mode, the EVFU information is automatically deleted from printer
memory. To print the form again, re-send the EVFU command.
Several key points to operating the EVFU are listed below.
• Send EVFU commands immediately following the Execute command or
the format form feeds.
• The EVFU can be unloaded by issuing an END LOAD command only.
• The number of lines slewed is dictated by the current line spacing (lpi)
setting.
• In those circumstances where the EVFU is being used to control the
forms length only, the IGP forms length parameter can be used in place of
the EVFU.
• The maximum number of EVFU channels is 192.
• Changing the LPI unloads the EVFU.
