Red indicator lights up Indicates unsuccessful read-after-write. The TTPM2 makes a
second attempt to encode and read the ticket. During that attempt
the red indicator will go out. For each unsuccessful attempt, the
red indicator lights up again. If a single-ticket operation is in
progress, the red indicator stays ON until a new ticket is inserted
and successfully processed. Also refer to the previously described
procedures regarding the yellow and green indicators.
Red indicator is ON If the Red indicator stays ON, even though ticket stock is present
in the selected entry station, this indicates that the paper path in
the TTPM2 has been blocked. Follow the description on the next
page to remove blockage.
Note • No data is lost in the process of detecting and acting on errors as long as the printer is
not switched OFF. If, however, the printer is switched OFF by mistake when an error is
attended to, two tickets will normally be lost. Because of the error, the ticket being printed
will be lost. The reason for the next ticket being lost is that even though the printer has
battery backed up memory which preserves data, it is not possible to guarantee that no data is
lost in the serial communication during the power OFF condition. It is, therefore, necessary
for the printer to erase the input buffer and wait for either an !C or an !P command before it
can synchronize printing to incoming data.
