QT-2100 Installation & Down Recovery Manual
With the QT-2100 system, the satellite terminal assumes that the master printer is down
when it could not obtain any response to its inquiry. The master printer is assumed to have
gone down in the following cases:
1) The power cable is disconnected from the outlet (the terminal or the printer).
2) Trouble with the inline between the terminal connected with the master remote printer
and the satellite terminal.
3) Trouble with the connection between printer and terminal.
4) Trouble with the terminal hardware connected with the master printer.
5) Trouble with the printer hardware.
Note that the master terminal or the remote printer is not really down in the first three cases.
When a satellite detects the master printer down, the satellite sends the data to the backup
printer automatically. (No operation is necessary at the terminal.)

1The terminal requires an inquiry about the printing data, but it cannot obtain any
response from the terminal with remote master printer.
2Then the terminal makes an inquiry to the terminal with remote backup printer.
3The terminal broadcasts remote printer down data to all terminals of the system.
When the remote backup printer or the terminal with remote backup printer goes down,
there is an option to retry printing/to display on the screen/to discard data.
