Weigh hopper occasionally 
overfills. 

Lower the hopper size under “Hopper Setup”

used 

Check the hopper’s scale calibration and verify that the hopper is 
not overfilling.  If the hopper is overfilling, adjust your hopper 
size.  If this is correct, then you are probably not accounting for 
material scrap or other items in your process. 

Printer did not print 

Check that the printer is a SERIAL printer.  If not, then you will 
need to either get a SERIAL printer or purchase a SERIAL to 
PARALLEL converter. 

 

 

The feeder calibration values 
are moving too much. 

Check to ensure that the weigh hopper is not touching any part of 
the frame and that the loadcell bracket is not touching the plastic 
cover of the loadcell.  If these have been verified then check 
loadcell and replace if necessary. 

 

I can’t calibrate the Scale 
without an error message. 

This Is caused by the difference in bits not being large enough.  
Using the Direct Scale Readout, examine current loadcell bits with 
and without the calibration weight.  If the bits do not change 
significantly, then check for pellets jamming the loadcells and 
check the loadcell circuit.  You might have a bad loadcell.
