TM200 Service Manual
Note:
The handshaking, data word length, baud rate, and parity depend on the DIP switch settings. Data transmitted from the printer has 1 stop bit (fixed)
Switching between online and offline
The printer does not have an online/offline switch. The printer goes offline:
When the cover is open
When an error has occurred
When the printer stops printing due to a paper-end(in cases when an empty paper supply is detected by either paper roll end detector or the paper roll nearend detector with a printing halt feature using
ESC c 4)
Interface connector terminal assignments and signal functions are described in the table below.

|
|
|
|
|
|
SPACE indicates that the host computer can |

|
|
When DTR/DSR control is selected, the printer |
|
|
|
transmits data after confirming this signal (except |
|
|
|
when transmitting data by DLE EOT, and GS a). |
|
|
|
|
|
|

1.5Buttons, Switches, and Panel Lights
Power Switch
Type: |
Rocker switch |
Function: |
The power switch turns the power on or off. |
Note:
Turn on the power only after connecting the power supply.
Panel Button
FEED button: |
If you push this button once and release it, the printer |
|
feeds paper for one line based on the line spacing set by |
|
ESC 2 and ESC 3. If you hold on the button, the printer |
|
will feed paper continuously. |
|
Paper feeding using the FEED button cannot |
|
be performed when the printer cover is open. |
Note:
The ESC c 5 command enables or disables the panel button. When the command disabled the button, it will not function.

1.8Paper Sensors
The printer has 2 paper sensors as follows:
Paper roll near-end sensor
The sensor detects a near-end of a paper roll.
When the paper roll diameter becomes sufficiently small, the sensor detects a near-end of the paper roll and the PAPER indicator lights on.
Paper roll end sensor
This sensor detects whether paper is present or not.
When the sensor detects a paper-end, the printer stops printing.
Note:
After installing new paper roll, close the printer cover; then the printer restarts printing.
Cover Open Button
When the cover open button (located to the right of the cover) is pressed, the printer cover is opened. When the cover is closed, the cover open button is latched.
Note:
Be sure to use the cover open button to open the printer cover. Do not open the cover during printing.
Do not open the cover during the autocutter is operating; otherwise the mechanism may be damaged.
Cover Open Sensor
The cover open sensor monitors the printer cover. When the sensor detects a cover open during printing, the ERROR light blinks and the printer stops printing. The printer recovers when the cover is closed.
When the sensor detects a cover open while the printer is in the standby status, the printer goes offline. The printer recovers when the cover is closed.
Note:
Whether the cover is open or not does not affect the status reported by the paper roll end sensor.
