Typical issues
16.1
Uneven surfaces (Distance between substrate and print head)
The T3 is designed as on all purpose over printer for printing on absorbing materials, such as paper, inkjet
coated substrates (PP, PE etc.) and even some wooden materials. Besides the requirement of an absorbing
surface, it is also important that the print surface is as even as possible.
It is important that the paper bag is as flat/smooth as possible, crumbled paper bags will result in a poor
print quality and smearing from touching the print head.
16.2
Print head too far
The image will look blurred (often seen as sand bank/fish bone like patterns in solid colours).
16.3
Print head too close
The image will smear.

The recommended distance between the print head and substrate is
0,7-1 mm
. Please consult the T3 user
guide on how to adjust the height.
16.4
Residual ink smearing on substrate
A clean wiper, cap and print head is important for the print quality, please refer to chapter 18.1 for details.
