8 ERROR
CODES
TTPM2 reports error conditions in the form of error codes. An error condition is reported
as a NAK (15H) followed by a one-character error code. The error codes have been de-
fined, starting with ASCII character "1" (31H) according to the following table:
"1"
No paper in the input path selected with !L1, !L2, !L17, or !L18.
"2"
Paper jam when executing !L1, !L2, !L17, or !L18.
"3" Reserved.
"4"
Cutter error. No full cut performed. Cutter blade returned to home position by
reversing the cutter motor.
"5"
Cutter error. Cutter blade not returned to home position.
"6"
Cutter error. Cutter blade not moving. If this error code is received immedi-
ately after power ON, it indicates that something is wrong with the +24V sup-
ply.
"7"
Paper jam when executing the !P command.
"8"
Magnetic encoding on track 2 (or center track) failed.
"9"
Magnetic encoding on track 1 or 3 failed.
"A"
Not possible to read magnetic information with !D command.
”B”
No document inserted within time limit following an !L3 command (front
load).
”C”
Document inserted (front load) but immediately retracted.
”D”
Document inserted through front load is blocked.
”E”
Document blocked in the front load input feeder during an !L3 command.
Also used when combining the characters | and } in a hex magnetic string to
get normal behavior if the encoding was successful. If an error occurs then
the ticket is transported back to the start position and NAK + ‘E’ is sent.
“G”
Document found in the ticket path during power on has been erased, VOID-
printed and ejected.
“P”
If !P is sent to the printer and paper is out, it replies with NAK + P and dis-
cards data.
1
"X"
Critical error. This is issued when the printer must be turned off, error condi-
tion cleared, then turned off again.
NOTE!
– For TTPM2 to send ACK, or NAK + error codes, the DIP-switch 6 on the
TTPM2 control board must be set to ON. The DIP-switch position OFF places the unit in
a silent mode preventing these codes from being transmitted to the host computer.
