To determine whether high frequency vibration is affecting the product or the print head, simply
pass a piece of paper under the print head and the trigger the print. Take care to move the paper at
a steady speed.
If it is the product which is vibrating, then the print quality will be good. If the print quality is poor,
the vibration is likely to be coming from the print head.
To test for print head vibration, pass a piece of paper under the print head in the same way as
described above, but this time hold the print head with your other hand to dampen any vibration in
it. If print quality improves as a result, then the print head is suffering from the effects of
vibration.
