Special features of the document processing
When processing documents, in contrast to the normal processing of single
sheets or continuous forms, the varying sizes of the documents and the docu-
ment feeding mode must be considered.
Insertion and ejection of documents
In principle there are two possibilities for controlling the insertion and ejection of
documents.
One possibility is that the printer initiates an insertion automaticallyat a holding
position (set ifnec essary by appropriate commands), when adocument is fed in
by the user. When the first print or positioning command for this document is re-
cognized, it will be drawn in and transported to the correct processing position.
If the document printer receives print instructions and no document is available,
the user will be requested to insert a document by a flashing LED indicator and
the LCD display on the operating panel.
The ejection of a document can be initiated by a form feed command.
Using a special CSI command, documents can also be drawn in explicitly to the
base of the first print line and processed; or documents only fed in can be ejec-
ted. Thus insertion and ejection procedures can be secured by means of sepa-
rate control cycles in the program.
