Character Sets and Global Commands 3-30
If the paper is not at the top-of-form position when the printer
receives the clear current path command, the printer executes a form
feed operation before attempting to park tractor-fed paper and
displays a prompt to PLEASE TEAR paper.
If the PAPEROUT=BUSY option in the Setup/Test menu is set to
YES, clearing (parking) the paper causes the printer to send a BUSY
signal to the host, which may suspend communication.
The clear-current-paper-path command (n = 1) is executed as follows:
q
With tractor-fed paper loaded, the printer parks the paper.
q
With friction-fed paper loaded, the printer ejects any cut sheets.
q
With no paper loaded, the printer accepts but ignores the command.
If tractor-fed paper is currently loaded, only the clear/park command
(n = 1) is executed; any other paper path command is ignored.
If friction-fed paper (cut sheet) is currently selected and loaded, the
command functions as follows:
q
Any command option to select another paper path causes ejection
of the current paper before execution of the command.
q
A friction-feed command for the currently selected paper path is
accepted but ignored.
q
A clear/park command (n = 1) causes ejection of the cut sheet.
