Safety instructions
Before installing and using the printer, please read the following items carefully:
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;
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) Do not disassemble the printer without permission of a technician, even for repairing purpose;
15) Keep this manual safe and at hand for reference purpose.

4 Installation and suggestion
4.1 Unpacking
Open the carton and check whether all items listed on the packing list are included or have any damages.
In case of damages or missing items, please contact your dealer or the manufacture for assistance.
4.2 Adjusting paper guide
Open the carton and adjust the paper guide to meet different paper width before installing printer.
BK-T680 can use paper adjustable from 48 to 82.5mm. Adjust the paper guide to right position as
showed in the following figure.
Three are six scale marks on bottom cover of paper guide: 82.5mm, 80mm, 76mm, 70mm, 56mm,
48mm. Remove the paper guide to adjust the gap to be aligned with the dot of target scale mark.
Figure 4.2-1 Adjusting paper guide
Note: Unscrew the screws that fix the paper guide in anticlockwise direction before removing the paper
guide (Don’t need to disassemble the screws completely.), and then tighten the screws after the paper
guide reaches the right position. (The default configuration of the screw is not assembled unless the
customer requires.)

4.3 Adjusting mark sensor position
The position of mark sensor on BK-T680 printer can be adjusted to right or left side, thermal or
non-thermal side. The mark sensor needs to be adjusted when following cases occur:
The position of mark on paper is inconsistent with the position of mark sensor (including right/left
side, thermal/non-thermal side).
Note: Please adjust the mark sensor before installing cantilever holder.
Steps to adjust the position of mark sensor to right/left side:
1) Make the cross screw driver deep in the printer in the direction shown in the figure 4.3-1, and then
rotate it in the direction shown by the green mark to adjust the position of mark sensor;
Figure 4.3-1 Adjusting mark sensor position
2) The bulge that aligns with scale mark indicates the relative position of mark sensor to the center
line of path as shown in the figure 4.3-2. Take out the cross screw driver when the sensor gets to
the right position.
Figure 4.3-2 Indicating mark sensor position
Steps to adjust the position of mark sensor to thermal/non-thermal side:
1) Refer to step 1 in “5.1 Cleaning mark sensor” to remove the paper guide module;
2) Refer to step 2 in “Cleaning mark sensor” to remove the screw module of mark sensor, and
exchange the upper and the lower screw modules of mark sensor, then the position of mark
sensor (thermal/non-thermal side) is changed.

shell and don’t pull the cable forcibly.
4.7 Installing paper roll and loading paper
Before starting to install the paper roll, make sure the specification of paper roll is in conformity with
printer requirements (refer to 2.2 Paper specifications).
4.7.1 Steps for installing paper roll
The paper roll installation of BK-T680 is quite easy, detailed operations are as follows:
1) Turn on the power and place the paper head into the paper feeding path as shown in figure 4.7-1;
Figure 4.7-1 Paper loading
2) The roller starts rotating when paper sensor detects paper presence to finish semi-automatic
paper feeding.
Note: Before loading paper, cut the paper head trimly as showed in the following figure.

BK-T680 User’s Manual
14
Figure 4.7-2 Paper head
Note: Before loading paper, make the radian of paper flat to ensure that paper loaded enters printer path
smoothly.
Figure 4.7-3 Paper head radian
4.7.2 Semi-auto paper loading
1) Turn on the power and the buzzer beeps for alarming paper end;
2) Refer to figure 4.7-1, push the paper into paper inlet slightly for a certain distance, and release the
hand when the platen roller starts to rotate and hold the paper;
3) The printer starts to feed paper and is possible to print when paper head stops at the normal
printing position after printer stops feeding paper.
Caution:
When pushing the paper into feeding path, the strength should be well-distributed and gentle, try to
make the front head of the paper parallel to the feeding paper path and the intersection angle
between paper center line and printer center line no more than 4° to avoid paper jams.
