Top Validation Operation - TransAct Ithaca 90PLUS Series Programmer's Manual

Programmer's Guide
After the eject form command, the printer will automatically reselect the receipt station if additional
print data is sent to the printer. This mode uses the same time delay as the open-for-validation
command without autoform sense. The delay specified must expire before the printer will close the
clamp and return to receipt mode. In this case, the form clamp will be held open for at least two
seconds. This time can be set from 1/2 second to two minutes, or it can be turned off (no time out).

Open for validation
[ESC] [DC1]

<27> <17>
&%VO
[ESC] c 0 <n>
The [ESC] [DC1] command opens the form compensation assembly for
validation. No automatic validation form sensing is performed. The application
must poll the printer for validation forms present and then issue a close
compensation command.
1. The command can be set to time out.
2. If data is sent to the printer after the command but before a close-for-
validation command, the printer will return to receipt mode and print the
data.
Close for receipt/validation
[ESC] [DC3]

<27> <19>
&%VC
[ESC] c 0 <n>
The [ESC] [DC3] command closes the form compensation assembly and enters
validation mode if either the top form sensor or the slip-stop sensor recognize a
form. If no form is sensed, the printer will close the form compensation assembly
and enter receipt mode. If a form is sensed, the printer will be in validation mode
until another mode is issued. After the validation operation is complete, an eject
form or open-for-validation command should be issued. The printer will not
count validation lines or sense the end of the form. The application should take
care to not print past the end of the form. There are two inches of validation
space. The receipt mode select command can be issued at the end of the
validation operation. However, the clamp will not be opened, and if a form is
sensed, the printer will enter dejam mode.
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.
