Safety Instructions
Before installing and using the printer, please read the following
items carefully.
1. Safety warning
The print head is a thermal element and it is at a high
temperature during printing or just after operation, therefore do
not touch it or its peripherals for safety’s sake.
The print head is an ESD-sensitive device. To prevent damage,
do not touch either its printing parts or connecting parts.
2. Notices
1) Install the printer on a flat and stable surface;
2) Reserve adequate space around the printer so that convenient
operation and maintenance can be performed;
3) Keep the printer far away from water source, and do not expose
the printer to direct sunlight, strong light and heat;
4) Do not use or store the printer in a place exposed to high
temperature, high humidity or serious pollution;
5) Do not place the printer in a place exposed to vibration or
impact;
6) No condensation is allowed to the printer. In case of such
condensation, do not turn on the power until it has completely
gone away;
7) Connect the printer power to an appropriate grounding outlet.
Avoid sharing one electrical outlet with large power motors or
other devices that may cause the fluctuation of voltage;
-3-
BTP-L540 User’s Manual
8) Disconnect the power when the printer is deemed to idle for a
long time;
9) Don’t spill water or other electric materials into the printer (e.g.
metal). In case this happens, turn off the power immediately;
10) Do not allow the printer to start printing when there is no
recording paper installed; otherwise the print head and platen
roller will be damaged;
11) To ensure quality print and normal lifetime, use recommended
paper or its equivalent;
12) Shut down the printer when connecting or disconnecting
interfaces to avoid damages to control board;
13) Set the print darkness to a lower grade as long as the print
quality is acceptable. This will help to keep the print head
durable;
14) Avoid turning on and off the printer frequently. It is advised to
turn on the printer at least 2 seconds after the printer is turned
off;
15) Do not disassemble the printer without permission of a
technician, even for repairing purpose;

Appendix 5 operation guide for paper loading under
peel-off mode (optional)
When using label paper with adhesive, the user can refer to “2.4
Installing paper roll” for installation, and the paper out mode can be
set to peel-off mode. When peel-off mode is selected, follow the
steps below to load paper:
1) Remove several labels on the front of label paper, ensure the
front of base paper is flush, and pull the peel-off turn board
outward (see figure appendix 5-1);
2) Pass the base paper through the peel-off module according to
the path shown in the figure (see figure appendix 5-2);
Figure appendix 5-1
Figure appendix 5-2
3) Push the peel-off turn board back into place and keep the base
paper in tension state to end paper loading.
4) When the printer is working, it peels labels off the base paper
and sends each label out one by one. After the user takes the
label away from the printer, the printer will continue to execute
the next command.
