4.6 Hexadecimal Dump Printing
This function is to print all received data in hexadecimal numbers. If problems
such as missing data, data duplication, etc. should occur, this function allows
checking whether or not the printer is receiving data correctly.
Set paper to the printer and keep the paper cover open. With the FEED switch
pressed and held, turn the printer power on and then close the paper cover.
The printer prints “HEX dump print mode” followed by the received data printed
in hexadecimal numbers and some characters.
CAUTION!
● The printer prints “.” if there is no characters corresponding to data.
● During hexadecimal dump, functions except some command will be disabled.
● If print data does not cover a line, press the FEED switch to print the line.
When you press the FEED switch three times consecutively, or you turn the
printer power off, or the printer receives a reset signal from the interface, the
hexadecimal dump printing is terminated.

4.7 Error Indication
●
Paper end
Paper empty is detected in two steps: paper near-end and paper end. It causes the ERROR lamp to light. If
paper end is detected, refill the paper. If the paper cover is open, a paper-end is detected.
●
Paper cover open
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.
