5. Sealing belt is easy to be
scorched.
4. Clean the surface of sealing belt in time
5. Clearance between two heating blocks
is too small or temperature is too high.
Embossing is not clear
1. Embossing wheel is worn out.
2. Pressing spring on embossing
wheel is not tightened enough.
1. Replace embossing wheel.
2. Adjust the tightening spring of
embossing wheel.
There is resistance
when the sealing belt is
conveying
The clearance between heating
blocks or cooling blocks is too
small, the friction is too much.
Adjust the clearance between sealing
belts properly, which should be about
thickness of packing bag in one layer, so
as to ensure strong sealing and clear
printing, but not make the two ends of
sealing part extend too long.
There is block or fold
phenomenon when the
packing bag is conveyed
to middle pressing
wheel or embossing
wheel
Too much pressure caused by
pressing wheel or embossing
wheel.

、
Adjust the pressing wheel or
embossing wheel to proper pressure, so
as to make the clearance between two
sealing belts be about thickness of
packing bag in one layer. So that not only
ensure the strong sealing and clear
printing, but not make the two ends of
sealing part extend too long.
2. Adjust limiting screw after adjusting
clearance.
Conveyor belt is
off-tracking
The active roller shaft is not parallel
to the driven roller shaft
1.Adjust the two adjusting screws of the
driven roller shaft (rear axle).
Conveyor belt and
sealing belt don’t move
synchronously
The conveyor belt is not tight
1. Tighten the chain of driving roller shaft
(front shaft) and middle shaft properly.
2. Tighten the conveyor belt properly
Solid-ink does not work
1. The power is not connected.
2.The main control circuit board
is not inserted or is in poor cont
act.
3. The main control circuit boar
d is damaged.
1.Check the power line is inserted or
not and the indicator light is bright.
2.Check whether the pin of circuit board i
s tight, and whether the wire lead droppe
d out.
3.Check the circuit board, and replace the
components.
Printing wheel does not
work
1. The contact of start sensor is
stuck
2. The sensor is not clean and the
photocoupler hole is blocked by
1.Remove obstacles.
2.Remove the dirt from the surface of the
optocoupler hole.
3.Check and replace components.
