Service Manual JET3
Rev. 1.0 27
The print head should be mounted to the printed product that the notch in the head cover
is placed vertical to the moving direction of the product. It can be installed horizontal,
vertical, from the top or from the bottom.
For installation from the bottom it has to be prevented that dirt can enter in the print
head. For this a head ventilation is required which can be purchased optionally.
The print head mounting should be carried out that a fast separation of the print head
from the device for cleaning purposes is possible.
The print head should be attached vibration-free. The hose connection
of the print head should not be smaller as a radius of R60 statistically
and dynamically not below R100!
The distance of the print head to the product depends on the required character height.
As smaller the required character height, as smaller the distance of the print head to the
product (smaller distances produce better type quality)
Note: In general a distance of round about 8-10mm is recommended.
For applications with extreme small or large character heights a micro- and macro print
head are available optionally.
Installation of print head
During an installation of a device in a production line, the operating
staff should be not endangered. Due to moving products under the
print head danger of bruisings and shearing can be caused. The
regulations of the machinery directives should be observed!
