During printing, do not open the paper cover. If you open the paper cover accidentally, the ERROR lamp blinks. Confirm the paper and close the over. Printing resumes automatically.

● Thermal head overheat

When you print dense characters or dark image, the head temperature rises. If the head temperature exceeds a specified level, the printer stops printing operation and waits till the head temperature is lowered. During waiting, the ERROR lamp blinks. When the head temperature is lowered, printing resumes automatically.

● Cutter lock

If the cutter blade stops operating due to paper jam or the like, the ERROR lamp blinks. Remove the cause of the trouble and press the FEED switch. If the blade does not move and the cover does not open yet even in the above procedure, follow the procedure in section 4.4 to open the paper cover.

● Black Mark detection error (in Black Mark mode)

When no Black Mark can be detected even if a certain amount of paper feed is carried out for Black mark detection, a Black Mark detection error occurs. If black detection continues more than the specified period, a No Paper condition is assumed and the same error as No Paper is indicated.

Lighting and blinking status of each error including the above is shown below.

Manual Setting of Memory Switch (Memory SW)

The memory switch can be selected, changed, or written by the combination of three actions: pressing the FEED switch, pressing and holding the FEED switch, and opening or closing the paper cover.

1. Entering memory switch setting mode.

Set paper to the printer and keep the printer cover open. With the FEED switch pressed and held, turn the printer power on, and then press the FEED switch twice. Close the cover. If the current settings of the memory switch etc. are printed, the printer is now in the memory switch setting mode.

Memory SW (1) 00000000

0: OFF state

1: ON state

2. Selecting memory switch

When the FEED switch is pressed short (within 2 seconds), printing occurs in the order of "Memory SW1" → "Memory SW2" → "Memory SW3" → "Memory SW4" → "Write/Factory Setting" → "Memory SW1" → ...... repeatedly. When the memory switch you want to change is reached, press and hold the FEED switch (for more than 2 seconds).

3. Selecting each switch item

There are eight setting items for each switch. Press and hold the FEED switch for long, the printer goes to the next item and prints the current setting of the item. Repeat pressing and holding till the item you want to change setting is reached.

Power ON notify setting (Valid)

OFF state: ERROR LED OFF

ON state: ERROR LED ON

4. Changing the setting

When the item you want to change is reached, press the FEED switch short. The changed set value is printed. (To return to the previous setting press the FEED switch short). When you press the FEED switch long, the set value is accepted and then the printer goes to the next setting item.

5. Returning to the memory switch select mode

When the setting of the desired content is completed, open the paper cover and then close the paper cover. This allows the printer to print the setting of the changed memory switch.

6. Saving the setting and exiting the memory switch setting mode

Press the FEED switch short to move to "Write/Factory Setting". Then press and hold the FEED switch. The printer prints the content of new setting and exits the memory switch setting mode to return to the normal standby state.

* Unless saving the setting is executed, the changed setting cannot be enabled.

7. Initializing the memory switch

When you want to return the memory switch setting to the initial state, go to "Write/Factory Setting" in the above procedure. Here, open the paper cover and press and hold the FEED switch till buzzer sounds. This allows the printer to return to the initial state.

* All the memory switches settings are returned to the factory set values.
