5. Turn the power off to exit HEX dump mode.
HINT
•
If you switch the printer to OFFLINE when there is less than 16
bytes per line, the printer goes to OFFLINE after a print-dump.
HEX DUMP MODE is reinitiated when the printer is put in ONLINE
mode.
•
The ONLINE LED blinks when there is still data in the buffer
memory in OFFLINE mode.
- 27 -
2.8 Printing
1. Turn on the power to the printer and the computer.
2. Check that the ONLINE LED lights.
When the thermal paper is not set, the OFFLINE LED blinks. When
the thermal paper is loaded, the OFFLINE LED lights. Press the
ONLINE button so put the printer ONLINE.
3. Send a print command from the computer to the printer.
Example:
Printing ABC in parallel input using BASIC
1. Set SWDIP switch 1-1 to ON.
2. Input LPRINT "ABC" on the computer, then press the return key.
The printer should print ABC.
If the printer does not print, see Section 7, Troubleshooting.
HINT
•
Some forms of BASIC use the PRINT# statement or the PR#
instead of the LPRINT statement.
2.9 Buffer Memory
The buffer memory, which has a capacity of about 28000 characters
(approx. 28KB), receives and stores data at high speed, greatly
reducing the time that the computer cannot be used while it outputs to
the printer. When the printer is ONLINE, data can be input during
printing until the buffer memory becomes full.
If the printer is turned OFFLINE when there is still data in the buffer
memory, the ONLINE LED will blink. Printing resumes when the printer
is turned ONLINE.

Handling the Battery Pack
A fully charged battery pack can print about 3000 lines (40 columns of
the number "8"). The battery discharges when it is not used for a long
time, therefore, immediately recharge the battery after purchase or after
long periods of storage.
NOTE
 Always use an SII specified battery pack.
Inserting the Battery Pack
1. Turn the printer over and open the battery cover as shown in Figure
1.
2. Connect the battery pack as shown in Figure 2, turn it so the label is
visible, insert it into the printer, and close the battery cover.
3. Close the battery cover.

Removing the Battery Pack
1. Remove the battery cover as shown in Figure 1.
2. Pull out the battery pack, grab the connector with your thumb and
index finger, and remove it by pulling up on it.
3. Close the battery cover.
Figure 1
Figure 2
Charging the Battery pack
1. Connect the AC adapter to the printer.
2. Turn on the printer. The Power LED will blink once every second
indicating the battery pack is charging.
It takes about 10 hours to fully charge the battery pack.
When the battery pack is fully charged, the Power LED stops
blinking and goes on.
3. Disconnect the AC adapter.
NOTE
 Always charge the battery pack in a location that is from 5C
(41F) to 40C (104F) otherwise it may lead to a degradation of
the battery pack.
 The printer does not charge the battery pack when the power is in
OFF state.
HINT
•
Battery charging is temporarily disrupted while the printer is
printing and resumed automatically when printing is completed.
- 30 -
When the Battery pack Gets Low During Printing
When the Power LED starts blinking about once every 0.5 seconds and
the printer goes OFFLINE, connect the AC adapter.
The ONLINE LED will blink if there is data left in the memory buffer. In
order to print the remaining data, connect the AC adapter as quickly as
possible and push the ONLINE button.
NOTE
 Battery pack efficiency will decrease if battery pack is recharged
more than necessary. Confirm whether Power LED is blinking and
battery charge has decreased before recharging battery pack.
 When using the rechargeable battery pack:
Turn off the Power Switch after use.
Leaving Power Switch ON will consume battery pack and
eventually run battery pack out, leading to low performance and
malfunction.
 When using the AC adapter:
If you are not using the printer, turn off Power Switch, and unplug
the AC adapter.

3 PRINTER FUNCTION
3.1 Buffer Full Printing
The DPU-414 has a line buffer to receive data in one-line units.
If data with more columns than one line is received, printing will start,
even if there is no print command.
This is called "Buffer full printing".
3.2 Interval Home Return
To protect the printer, the head returns to the home position (the leftmost
position) automatically when;

data is not sent from the computer

the ONLINE button is pressed to set the printer OFFLINE

the printer runs out of the thermal paper
3.3 Errors
Both the ONLINE and OFFLINE LEDs and data input and paper feed are
disabled when one of the following four errors occurs:
A
The head does not return to the home position even when the power is
turned on;
B
The head does not return to the home position at interval home return;
C
Printing is attempted at extremely low or high ambient temperatures;
D
The battery runs out;
- 32 -
If an error occurs:
A or B:
1. Turn off the Power Switch.
2. Remove the foreign material.
3. Turn on the Power Switch.
C:
Use the printer at 0C to 40C (32F to 104F).
D:
Connect the AC adapter and turn on the Power Switch to charge the
battery pack.
3.4 Out-of-Paper Detection
When the thermal paper runs out, the printer goes OFFLINE and the
OFFLINE LED flashes. The printer cannot be set ONLINE while the
OFFLINE LED is flashing. When the thermal paper has been loaded, the
OFFLINE LED stops flashing, and stays lit. Press the ONLINE button to
print.
If the thermal paper runs out during printing, the printer will go OFFLINE.
Load new paper and press the ONLINE button to resume printing.
