5.2. Diagnostic information
Holding FEED button while power on for ~ 0.5 sec (STATUS LED lights) – short self test
Holding FEED button while power on for ~2.5 sec (one beep and POWER LED turns green) –
start DUMP mode. All input data are printed hexadecimal and as text.
Holding FEED button while power on for ~8.5 sec (4 tone sound signal) – enter firmware
updating mode
Holding POWER button while power on for ~2.5 sec (one beep):
If cable is connected (RS232 communication) – temporary forcing bps serial speed to 9600
If no cable is connected (Bluetooth communication) – starting a hardware menu for fast
Bluetooth pairing info reset.
Holding POWER button while power on for more than 6 sec(printer prints) – enter hardware
menu
5.4. Loading paper
Press the cover open button to open the paper cover

6. Functions
6.1. Self test
The DPP-255 has a built-in test pattern that shows the printer’s current configuration as well as the
various resident printer fonts. The self-test can also be used as a troubleshooting tool to determinate
problems or battery level.
Holding FEED button while power on for ~ 0.5 sec (STATUS LED lights)

UM 07.01.01/v1.0.0 14
6.2. Page mode
In page mode the result the result of incoming commands is forwarded to a reserved memory
area (page). The page place and size is defined using commands ESC W. Command GS T selects the
print direction in this page. At the end the collected information is printed using one of the
commands, provided for this. Commands ESC FF and GS FF print only the currently defined page, but
command ESC Z prints the area between the first and last line containing at least one black point.
All commands except GS L and GS W work in page mode. The centering and right alignment
(command ESC a) id working in the currently defined page width.
6.3 Ruled lines
The printer has two line buffers with size the maximum printing width (paper width in standard
mode or the selected page width in page mode). When ruled lines are active, then every horizontal
line of the text line is combined with the selected ruled line buffer. Bit ‘1’ in the ruled line buffer is a
black dot in OR mode and inverts the color of the dot in XOR mode. Two commands allow the ruled
line buffers to be printed without combining with a text line.
When pressing the FEED button, no ruled lines buffer is applied.
All ruled lines commands start with symbol DC3 (ASCII code 13h). Please see command DC2 =, too
6.4. Protocol mode
The purpose of this mode is to give stronger real time access to the printer. All input data are
sent in packets. The printer returns an answer to the packet immediately.

No error signal Is detected
- Standby – It is possible to print and the printer waits for printing data
- Initialization – Initialize printer memories. The printer goes OFFLINE during
initialization. After completing initialization, the printer goes stanby.
- Status of waiting error cancellation – Printer status move to this status when some
error factors like paper end etc. is removed. OFFLINE status and STATUS LED remain its
status. Printer becomes standby when FEED button is pressed.
Status of detecting errors
- Temperature – The print head temperature is increased when heavy-duty printing is
continuous. If the print head temperature exceeds 70 degreesoC, operation of the
print head is automatically stopped to prevent overheating. The printer goes OFFLINE.
- Paper empty – Detect the paper empty through paper end sensor. Paper runs out and
the printer detects paper empty, the status LED turns On and the printer goes OFFLINE
- Paper cover open – When the Paper cover open, the status LED turns ON ant the
printer goes OFFLINE

8. Maintains
Periodically clean the printer to maintain the printing quality and avoid failures.
Roll Paper: It is recommended to maintain the printer every 6 months or 1 million lines of printing.
Label Paper: It is recommended to clean up the printer head and roller everyday or every five rolls.
Thermal head
When cleaning the thermal dot line on the print head, use a cotton swab with alcohol (ethanol,
methanol or Isopropyl alcohol) and wipe off stains and dust.
Paper feed roller
When cleaning the paper feed roller and peeler roller, use a cotton swab with alcohol (ethanol,
methanol or Isopropyl alcohol) and wipe off stains and dust while rolling the roller. Isopropyl alcohol
is available to wipe deposited dirt.
Sensor and peripherals
Clean the stain, dust and paper powder on the paper empty sensor and paper cover sensor.
Peeler Unit
It’s necessary for using continuously and smoothly to clean accumulated residue of paste from
peeler unit as shown below, or the unit won’t work because of the residue.
If the sign appeared, please clean up peeler unit.
Indication of regular cleaning is once per five rolls.
o Prior to maintenance work, be sure to turn OFF the printer.
o Avoid cleaning the print head immediately because the print head is hot. Start maintenance work
after the thermal head becomes cool.
o Do not touch the print head with fingers directly. It may cause damage by electrostatic discharge and
contamination.
o Do not touch the thermal head dot line with bare hands or metal objects.
o Do not use volatile chemical agents, such as thinner and benzene.
o Do not get moisture or spill liquids inside of the printer.
o Turn ON printer only after alcohol is completely dried.
For maintenance and service, please contact you Datecs local distributor.
