Physical Page Characteristics of the LA75 Plus Companion Printer
2.1 Paper Handling
The LA75 Plus Companion Printer uses the form length, as determined by the
setup feature or by the Set Lines Per Page (DECSLPP) command, to compute
the tops of forms other than the first.
Fanfold Paper — Bottom Feed/Rear Output (Pull Tractor Mode)
In this mode there is no autoload function, so the printer cannot detect the top
of form.
The power-up paper position is assumed to be the top of form.
Cut Sheet Paper — Manual Feed/Top Insertion and Top Output (Friction
Mode)
Paper is considered autoloaded when the printer loads it automatically at
power-up or when the user presses the Form Feed (FF) button.
Paper is considered manually loaded when the user inserts it using the platen
knob.
Automatic Sheet Feeder (Friction Mode)
When the sheet feeder is installed and selected there is no manual load
function.
Sheets are automatically loaded when the user presses the Form Feed (FF)
button or when characters are received to be printed.
Manual Feed Mode with Sheet Feeder Installed
The sheet feeder can be deselected by the DECASFC command.
When the sheet feeder is deselected, paper can be inserted manually.
In this mode, the printer works as in Cut sheet paper/Manual feed, except that
the backward motion features (Parking and Viewing) are disabled.
To reactivate Automatic Sheet Feed mode, the DECASFC command must be
used. Alternatively, the sheet feeder can be reselected by turning the printer
power off, then on again.
2.2 Response to Form Feed (FF)
The following information refers to paper motion when the Form Feed (FF)
control code is received; actions that occur when the user presses the Form
Feed (FF) button are not covered.
Fanfold Paper — Rear Feed
When paper is autoloaded, Form Feed (FF) advances the paper to the next top
of form.
