● Cover open
The printer lid is opened.
● Fatal errors
In the following cases, the printer recognizes them as fatal errors and enters the fatal error mode. The fatal error condition cannot be recovered until turning the power off.
●Carriage does not move correctly
●Control circuit cannot work correctly
When the error condition is detected, the printer automatically enters ‘PAUSE’ mode and outputs appropriate interface signal.
When parallel interface is selected, the following interface signals are outputted to indicate the error and to stop data transmission.
●BUSY signal becomes HIGH
●ERROR signal becomes LOW
●Output no ACKNLG pulse
●PE signal becomes HIGH (only paper out error)
1.6.5 Buzzer Operation
The buzzer sounds under the following conditions:
● A paper-out error is detected (beeps 3 times for 0.1 second respectively, with 0.1 second intervals).
● Ink end error is detected (beeps |
5 times |
for 0.1 second respectively, with |
0.1 second intervals). |
||||
● Cover |
open |
error is detected (beeps 5 |
times for 0.1 second respectively, |
with 0.1 second intervals). |

is detected (beeps 5 |
times |
for |
0.5 second respectively, with |

●When panel setting is accepted (beeps 1 time for 0.1 second).
1.6.6Printer Initialization
There are three initialization methods: hardware initialization, software initialization, and panel initialization.
(1) Hardware initialization
This type of initialization takes place when |
the printer power button is turned on with the AC power |
cord plugged in or when the INIT signal is |
received. |
When the printer is initialized, it performs the following actions:
(a)Initialize printer mechanism.
(b)Clears input data buffer.
(c)Clears downloaded character set.
