7.1 Input Buffer Back-up

If the power is turned off, or there is a power failure during printing, the data in the input buffer willbe retained.

When the power comes back on, the power failure symbol (..... PD) will be printed in red, and then the data which

was interrupted will be printed from the beginning of the line where the interruption occurred.

Note: The input buffer back-up function may not operate properly if the related capacitor is not sufficiently

charged. This may be the case if the printer has not been operated for a long period of time. After the printer
power switch has been turned on for 10 minutes, the buffer back-up should be effective for approximately
100 hours or m ore.

(4) Data Receiving Control

Your printer is able to receive data sent from the host side when the BUSY signal is LOW, but unable to receive
when the BUSY signal is HIGH.

(5) Buffering

1) N Type
Your printer is provided with a two line input buffer.

2) B Type
Your printer is provided with a 7K byte input buffer. This makes possible a large amount of data buffering,
and therefore, the host side is free immediately after data transmission.

9.3 Description of Input/Output Signals

(1) Input/Output Signals

a) RD :

This is the serial signal for received data. When framing, overrun or parity errors occur, the data concerned are
ignored.

b) DTR :

Please write in data or c ommands when this signal is in a "ready" state. If written in when in a BUSY state, an
overrun error will occur and the data will be ignored. Data can be written into the input buffer even during
printing. Further, a BUSY signal is gene rated when the power is turned on, while test printing, when
ONLINEE and during reset.

c) FAULT :

When there is a problem in the printer mechanism the FAULT signal will be issued, and all control circuits will
be interrupted. To RESET this signal, first correct the cause of trouble in the printer mechanism. Then, by
pressing the LINE switch or by inputting "0" (LOW LEVEL) at the RESET terminal, the FAULT can be
cleared.
Causes of the FAULT signal are lack of paper and errors in the printer mechanism. Printer errors include such
as, the print head stopping during print operation or failure of the print head to return to the home position.

d) RESET:

This signal resets the entire printer.

e) PE :

This signal is output when the paper roll is near the end.

f) TD (Valid only for type B):

When receiving data signals, and when the printer's input buffer has less than 1K bytes remaining open, the
DC3 code (13H) is issued, indicating that receipt of data is not possible. When the data in the input buffer is
reducedto 2K bytes, the DC1 (11H) code is issued, which indicates that data receipt is possible.

g) FG:

Frame Ground

h) GND:

Common ground for all circuits.

(2) Data Composition

[1] Start bit
[2] Data bits (andparity bit)
[3] Stop bit (1 bit or more)

[1] Start bit

1/2 bit past the line dropping from MARK to SPACE, a status reading is taken again. If the reading is SPACE,
a st art bit is recognized, but if it is MARK, it is not taken as a start bit. T his is not regarded as an error, but the
search for the start bit is performed once again.

[2] Data bit andParitybit

Data bits and parity bits are the data of the bits in question, which are represented by the state at the times
sampling is performed. This is accomplished at time intervals equal to one bit in length, beginning from the

middle of the start bit. The order of the bits is, starting with the bit closest to the start bit, bit-0, bit-1 ....., pa rity

bit. (Note: data bits are based on "one point sampling".)

[3] Stop bit

The stop bit consists of one or more bits at "mark" level. When "space" level is detected for a stop bit, a framing
error occurs.

(3) Error Detection

Parity, framing and overrun errors can be detected by your printer. When an error is detected, the ALARM
lamp goes on, the buzzer is sounded, the related data is abandoned, and the printer shifts to the next incoming data.
The ALARM lamp can be turned off by pressing the LINE switc h.

[1] Framingerror

When "space" state is detected during stop bit sa mpling,the ALARM lamp goes on, the buzzer sounds, and the

related data is ignored.

[2] Parityerror

When parity check is designated, and if when checked an error is detected, the ALARM lamp goes on, the

buzzer sounds and the related data is ignored.

[3] Overrunerror

When an overrunerror is detected, the ALARM lamp goes on, the buzzer sounds and the related data is ignored.

CBM-710/720/730/750 User’s Manual

29 CITIZEN

[4] Other errors

When trouble is detected in the printer mechanism, the ALARM lamp goes on, the buzzer is sounded, the

FAULT signal is output, and the DTR signal becomes BUSY. After the cause of the trouble has been corrected,

theALARMlampcanbeturnedoffbypressingtheLINEswitchorbymakingRESET="0".Whentheprinter

is put ONLINE, data receiving restarts.

(4) Data Receiving Control

When the BUSY signal is LOW, your printer receives data from the host side, but when this signal is HIGH, it
cannot receive data.

(5) Buffering

Data transfe r to the input buffer is controlled by the DTR and TD signals. Please refer to 9.3 b) for the DTR
signal and 9.3 f) for the TD signal.
