8 SINGLE-TICKET
HANDLING
8.1 Overview
The TTPM2 comes with one of two different single-ticket-handling systems: upper rear
entry load (standard), and front load (optional). In both cases, the upper document track
of the printer is used for the single-tickets.
This means that single-ticket processing restricts the use of fanfold ticket stock to the
lower track.

Previously encoded tickets
One use of the single ticket handling is to process a ticket several times. For example, if
you issue a return train ticket (Stockholm to Oslo and back to Stockholm) you can add
print, and re-encode the magnetic stripe when the first part of the journey is made.
1. Use the applicable decode command to read the previously encoded ticket informa-
tion.
2. The data is transmitted to the host computer, and the ticket is positioned in the active
position of the upper track, ready for a new encoding and printing.
3. Printing and encoding is effected using the same commands as for processing a ticket
from a fan-fold ticket stock, and the ticket is ejected to the customer.
TIP!
To avoid printing on top of the existing print of a previously used ticket:
•
Include information in the magnetically encoded string, about which area of the ticket
has already been used for printing
•
Read the magnetic stripe and let the host computer position new text on free spaces
of the ticket.
