Description
These commands open the form compensation assembly for validation. When
the form is sensed, the printer automatically clamps it. Data sent to the printer
after the select validation mode command will be printed in validation mode.
The eject form command should be used to release the validation form at the end
of the transaction. The [ESC] [DC4] command requires that the form be inserted
to the right and completely down in the printer to be clamped. The [ESC] j <n>
command allows the positioning of the form to be selected.
If <n> = 1, the form may be placed anywhere in the print area; it need not be all the way to
the right. It must, however, be completely down in the printer.
If <n> = 2,
the form must be placed all the way to the right in the print area; it need not be
all the way down. The form will be clamped after the right sensor detects it. The
form must be manually positioned to the print line.
If <n> = 0 or 3,
the form must be placed all the way down and to the right in the print area. The
form will be clamped after both sensors detect it. This command is the same as
[ESC] [DC4].
Notes
1. All station select commands reset rotated print and print justification. Print
is set to 0
°
rotation with left justification. If rotated print or justification is to
be set, it must be set after the station select command.
2. Any data that is sent to the printer after an eject command is printed on the
receipt.
3. The command can be set to time out.
4. See validation control for additional control commands.

[ESC] c 0 <n>
Description
The [ESC] i command operates front-slip mode and takes several steps to
complete.
1. The front slip throat is opened, and the printer waits for a slip to be inserted.
2. When a slip is sensed, it is clamped. The slip is then fed up to the form
position sensor. The sensor is located close to the top feed rollers and to the
right side of the printer. The sensor location ensures that the top of the form
is accurately positioned and the form is not skewed. The operator should
