TROUBLESHOOTING
Symptoms Cause Remedy
POWER SUPPLY
Machine not
warming up
Power cord
Fuse
Connect the machine to power outlet.
Check the fuse and change if necessary.
ADHESIVE APPLICATOR
Adhesive
not spread
evenly
Not enough hot melt in
the reservoir
Adhesive roller does
not rotate properly
Add hot melt adhesive.
Check the cable and driving wheel connected to roller.
Adhesive
applicator is
difficult to
move or
jammed
Glue not warm enough
or still solid
Mechanical block
Adhesive overcooking
Switch the machine on and the power indicator lights up
green. Let the machine warm up properly (20 min).
Inspect the adhesive reservoir visually and remove any
foreign objects.
If the machine is turned on but not used for a very long time,
adhesive will degrade and turn into a plastic like substance
blocking the roller. Contact your dealer.
BINDING
Spine shape
not
satisfactory
Paper block jogged
poorly
Short nipping time or
low compressing force
Back support and or
levelling plate not clean
Wrong nipping to
ol
Nipping tool
misalignment
Jog the paper block carefully and align it with the paper guide.
For the best results, press firmly for 5-7 seconds.
Clean the levelling plate and back support regularly. Lock the
clamp completely.
Use H-nipping tool for hard covers and S for soft covers.
A properly aligned nipping tool is parallel with the back
support
support to ensure even
compression
when the hand lever is pressed
down. Use nipping tool’s adjustment screws to eliminate any
clearance between nipping cams and nipping tool.
Binding
strength not
sufficient
Adhesive applied too
slowly
Nipping began too late
or the time was too
short
Poor adhesive quality
or low temperature
Book bound against
paper fiber direction
With the four step adhesive application method, the whole
cycle takes 4 - 6 seconds. Average time for a single back and
forth application is between 3 and 4 seconds.
Start nipping in 1 – 2 seconds after adhesive application.
The sooner the better. Proper compressing time is between
5 – 7 seconds.
Use Fastbind hot melt type 1adhesive. Normal operating
temperature for the adhesive applicator is 170 - 180 °C.
Highest binding strength results when the cover and papers
are bound along the fiber direction.
