Abstract

Paper jams and buckling can occur during unattended printing if the platen is reverse indexed above the default line and then forward indexed. The default line is the first possible writing line on the paper when the leading edge is under the printer paper bail. In order to reduce jams and buckling, a code is stored each time the paper bail is either opened or closed during preparation of a job for unattended printing.

Paper Bail Actuation During Unattended Printout

Paper jams and buckling can occur during unattended printing if the platen is reverse indexed above the default line and then forward indexed. The default line is the first possible writing line on the paper when the leading edge is under the printer paper bail. In order to reduce jams and buckling, a code is stored each time the paper bail is either opened or closed during preparation of a job for unattended printing.

A multicolumn format can require that text be printed higher on the page in a second column than in the first column. Upon input keying during preparation for unattended printing, if the first line of the first column is printed on the default line, the paper bail is closed for holding the paper against the platen. When closed, a close code is stored. After completion of the first column, the platen is reverse indexed above the default line for printing the first line of the second column. The paper bail will not be holding the paper at this time.

As the platen is forward indexed for subsequent lines, the default line will be approached. To prevent buckling and/or a paper jam, the paper bail is opened and an open code is stored. When the default line is reached, the paper bail is closed and a close code is stored. During this preparation for unattended printing, the text is also stored. Upon later unattended printing of the stored text, the reading of open and close codes will cause the paper bail to...
