6.6 Self Test Printing

Your printer has a built in self print function for purpose of checking print operation without the need for a ny
other external device.

Procedures for Actuating the Print Function

1) Be sure that a paper roll is properly loaded.

2) Confirm that the ribbon cassette is properly installed and turn the power switch off.

3) Turn the power switch ON while pressing the LF switch, and release the LF switch after the self test
operation has begun.

In the above operation, the self print function will stop automatically when completed.
However, the self print function will not operate without paper.

6-7. Alarm and Paper Near-End Detection

This printer has the paper near-end sensor to stop the operation when the paper comes to near-end, sending out
both BUSY and FAULT signals. This status is indicated by the SEL / ALARM lamp blinking at an interval of

1.0 second.

7. Input Buffer Back-up Function

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 will be
retained. When the power comes back on, the power failure symbol (…..PD) will be printed, 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 24
hours or more.

7.2 Clearing the Input Buffer

In case it is desired to delete the data in the input buffer, the power switch should be turned on while pressing
the SEL switch. When deletion of the buffer is completed the buzzer will sound.
Please be sure to continue pressing the SEL switch until that time.

If the printer fails to work properly at the time the power switch is turned on, please delete the input buffer as
described above before inputting new data.

8.3.4 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.

8.3.5 Buffering

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

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

9.3 Desc ription of Input / Output Signals

9.3.1 Input / O u tput Signals

a) RD:

This is the serial signal for received data. When framing, overrun or parity errors occur, the data is
converted into (7FH).

b) DTR:

Please write in data or commands when this signal is in a “ready” state. If w ritten 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 generated when the power is turned on,
while test printing, when ONLINE 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 SEL 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 of failure of the print head to r eturn
to the home position.

iDP3540/3541 User's Manual

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 reduced to 2K bytes, the DC1 (11H) code is issued, which indicates that data
receipt is possible.

g) FG:

9.3.2 Data Composition

[1] Start bit
[2] Data bits (and parity 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 start bit is recognized, but if it is MARK, it is not taken as a start bit.
This is not regarded as an error, but the search for the start bit is performed once again.

2) Data bit and parity bit
Data bits and parity bits are the data of the bits in question, which are represented by the state at the
time 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…..., parity 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.

9.3.3 Error Detection

The printer detects Parity, Framing and Overrun Error. When any error is detected, the data is
converted into (7FH).

1) Framing Error
Framing error occurs when SPACE signal is checked out at STOP BIT.
And the data is converted into (7FH).

2) Parity Error
When parity check is designated and if the parity error is detected, the data is converted into (7FH).

3) Overrun error
When an overrun error is detected, the data is converted into (7FH).

4) Other er rors
When trouble is detected in the printer mechanism, the SEL / 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, the SEL / ALARM lamp can be turned off by pressing the SEL switch or by making
RESET = “0”. When the printer is put ONLINE, data receiving restarts.

9.3.4 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.

9.3.5 Buffering

Data transfer to the input buffer is controlled by the DTR and TD signals.

14. Maintenance

14.1 Maintenance Procedures

It is recommended that users perform periodic cleaning of their printer.

14.1.1 Exterior

The exterior case of the printer can be cleaned with alcohol. Care should be taken to keep water
from reaching the electronic parts and the printing mechanism.

14.1.2 Interior

There is no particular requirement, however, when the printer case is opened to change setting etc.,
dust and other foreign matter may be removed from the printer mechanism and circuit boards with a
soft brush.
Special care should be taken to avoid damage to electronic parts and wiring. Furthermore, be sure to
disconnect the power plug from the electric outlet before opening the printer case.

15. General Cautions

1) Never operate your printer without loading paper and ribbon cassette. Any printing without

paper and ribbon cassette may cause damage to printer head.

2) Replace ribbon cassette before it is worn with rents.

3) Be careful not to drop any foreign matters, such as paper clips, pin and the like into your printer.

Those can cause mechanical trouble.

4) Nothing shall be placed on the radiation vents to the printer.

5) Place your printer always on a stable desk which is set horizontal.

6) No organic solvent (thinner, benzin or the like) shall be used in sweeping clean the surface of the

main body case.

7) Make sure that the power of the printer is turned off whenever you do the following.

(1) Taking out any foreign matter which were dropped into the printer.
(2) Replacing the ribbon cassette.
