2. The first printing page for a reception, a substitute file output, a report or a pattern output
may be blank. (AFO/AF2)
[Cause]
1. By a software fault, the DC loop over the OH relay is closed during an incoming call to result
in putting the ringing voltage (energy) through the DC loop.
The current faulty program allows the rin gin g off signal be enabled during a r inging sequence, so the OH relay is to be switched on.
Possible occurrence rate is ;
1/1800 ∼ 1/8300 at incoming calls.
(For more details, refer to page 3.)
2. By a software fault, the command for 24V power supplying to the thermal head may be
turned off instantly.
However, the printing sequence continues to result in a blank page outputted.
This is caused by the faulty priority assignment of the signals of 24V power on, of status
check and of RXSTART trigger.
It may occur at random as 36 µs/160 ms ≅ 1/4400.
