2-3. Handling Notes

(1) Install the printer near an easily accessible socket-outlet. (2) Place the unit on a flat and stable surface for operation. (3) Do not connect the AC Power Plug to the same outlet used for other noise

generating devices (large motors, etc.).

(4) Be careful not to drop paper clips, pins and other foreign objects into the

unit.

(5) Wipe off dirt with a soft cloth soaked in alcohol or benzine. Do not use

Lacquer thinner, Trichlorethelene or Ketone solvents because they may

damage plastic parts. (6) Use a soft brush, etc. for cleaning the printer mechanism and PCB. (7) Keep hands out of printer while power is on. (8) Do not attempt to print when there is no ink ribbon or paper in the unit. The

print head life could be severly reduced. (9) If the paper is fastened tightly to the roll, the paper may not detach from the

roll when the end is reached.

If this happens, the no paper detection function and paper feed will not

operate. (10) Always keep the printer cover attached when printing to prevent paper

jams, noise, and other problems. (11) Always turn the power off before opening the printer cover. (e.g. When

renewing a ink ribbon)

because it can get very hot.

Figure 4-1. Printer Cover Removal

(2) Unwind ribbon so that the spools are separated as shown in Figure 4-3.

Hold the ribbon taut as shown with the drive pins facing down and slide the

ribbon between the print head and the platen. While keeping the ribbon taut,

wrap one side around the black ribbon guide on the end of the platen and

drop one spool on the spool shaft. As you move the spool downwards, move

the detecting lever aside to allow the spool to drop into place. Make sure the

spool drive pins engage with the spool drive holes. As the spool drops into

place there will be a click. (3) While continuing to hold the ribbon taut, install the remaining ribbon spool

in a similar fashion. (4) Turn the spool that rotates freely to take up the ribbon slack.

OUTLINE

This code causes the printer to perform validation printing of a maximum of 32 subsequent characters (at 15 CPI, from the thirteenth to the forty-forth column). After the GS code is received, a maximum of 32 characters should be input, followed by the LF code which indicates the end of the validation printing data. (At this time, control codes except FS, ENQ, CAN and SUB codes, or any character received beyond the limit of 32 characters are ignored.) When the printer enters the validation mode, the ribbon is shifted up and the ON-LINE lamp blinks. (This lamp goes on and off at a 0.5-second interval until the end of the validation mode.) After the material to be validated is inserted, and the LF button is pressed, the validate line is printed, followed by a single line feed. When the check is removed and the ON-LINE button is pressed, the printer returns to regular mode and is set to ON-LINE status.

REMARKS

1) The print settings by commands (such as emphasized mode and underline mode) are invalid only during val-

idation printing.

2) When the CAN code is received in the validation mode, the printer returns to regular mode, and the mechanism is initialized.

3) If the FS or SUB codes is received in the validation mode, these codes are executed just after the printer returns to regular mode.

4) In the validation mode, the LF button and the ON-LINE button do not work except the above behavior.

5) If the printer has a Red black ribbon installed, the validate line will be printed in red.

9. DATA STRUCTURE AND CONTROL

9-1. DTR Mode (1 BLOCK)

Controls Data Transfer by using DTR line as BUSY FLAG (a)

(b) In case of Paper Empty

Paper Empty

When the paper out detector indicates end of paper, the printer stops printing after a maximum of two lines of printing or paper feed. The printer goes OFF LINE and sets the DTR to “MARK” status immediately after occurrence of a paper empty. It is necessary to install paper into the printer and press the ON LINE BUTTON to light the ON LINE LAMP in order to recover from paper empty status.

Machine Error

A machine error may be generated by paper jamming or when the printer is unable to print data. When a machine error occurs the printer stops printing. The printer goes OFF LINE and sets the DTR to “MARK” status immediately after the occurrence of Machine Error. It is necessary to turn the printer power off and on again in order to recover from Machine Error.

– 39 –

9-2. X-ON/X-OFF Mode

The printer transmits an X-ON (Control Code; DC1, Hexadecimal Value; 11H,) signal after power is turned on, if there is no printer error being generated. When this signal is received by the host computer, the host computer transmits the data to the printer. The X-ON signal is output intermittently every three seconds until the host computer receives and responds to this signal. The X-OFF (DC3, 13H) signal outputting begins when the amount of empty space in the buffer becomes less than 256 bytes. When the computer receives the X-OFF signal, it will halt data transmission as soon as it can. However even at this time the printer can receive data until the buffer is completely full. An X-ON signal is output when the contents of the buffer goes below 256 bytes. The increase of the empty area in the buffer is caused by printing. If the computer causes a buffer overflow, a flag bit in the status register will be set. (See Status) The X-OFF signal will continue to be output at a 3-second interval until the data buffer becomes near empty (less than 256 bytes).

– 40 –

Paper Empty

When the paper out detector indicates end of paper, the printer stops printing after a maximum of two lines of printing or paper feed. The host computer can receive the printer status by transmitting an ENQ code to the printer. The printer goes OFF LINE and sets the DTR to “MARK” status in 5 seconds after occurrence of a paper empty. It is necessary to install paper into the printer and press the ON LINE BUTTON to light the ON LINE LAMP in order to recover from paper empty status.

Machine Error

A machine error may be generated by paper jamming or when the printer is unable to print data. When a machine error occurs the printer stops printing. In the X-ON/ X-OFF mode, the printer outputs an X-OFF signal immediately. At this time the host computer can receive the printer status after transmitting an ENQ code to printer. The printer goes OFF LINE and sets the DTR to “MARK” status within 5 seconds after the occurrence of Machine Error. It is necessary to turn the printer power off and on again in order to recover from Machine Error.

STATUS

Parity

In DTR mode and X-ON/X-OFF mode parity check is done on vertical parity only.

Framing Error

Framing Error occurs when SPACE signal is detected at STOP Bit time. Framing error and vertical parity error will be indicated by printing “?”.

– 41 –

9-3. STX-ETX Mode

The start of the STX-ETX mode should occur with a totally empty print buffer. This can be achieved by sending an ENQ code to the printer and checking the status until the status code indicates an empty buffer. At that point, the STX code is sent by the host computer followed by a data block. While receiving the data block, the printer generates a horizontal parity check character. After the data block is sent, the host computer sends an ENQ which causes the printer to return 2 characters, one would be the normal status character, and the second would be the horizontal parity check character that was generated by the printer while the data block was received. The host computer checks the status character to determine if any vertical parity errors or other errors occurred during block transmission, and checks the horizontal parity character against a character generated in the host computer while the data was transmitted. If there are no errors, ETX causes the buffer to be printed, but if an error is detected, CAN code clears the buffer and the data is transmitted again. Any control codes transmitted to the printer during the STXETX mode will be ignored as control codes, but will be included in the check character. This is done to prevent a control code received in error from causing printing of erroneous data.

STATUS

Parity

Vertical and horizontal parity check is executed in STX-ETX mode.

Framing Error

Framing Error occurs when SPACE signal is detected at STOP Bit time. Framing error or even vertical parity error will be indicated by printing “?”.

When printer power is supplied by the user rather than through the accessory power source unit, please be careful of the following points.

Note 1: The power supply must be +12V 2A or above. An electrolytic ca-

pacitor (C = 4700µF/25V to 6800µF/25V) must be connected across the output of the power supply.

Note 2: A DC power plug is available as an option.

Reference: Design the power supply referring to the power supply circuit shown

below.

Note: A line noise filter must be used to prevent line transients from passing

through power supply. Filter design to be determined by environmental noise requirements.
