Top Mounting Bracket - Weber Markoprint XB4JET Manual For Installation, Operation And Maintenance

Installation and initial operation

Top mounting bracket

In preparation
Note the following if the Multiline MX / XR Top mounting bracket cannot be used
and you have to use your own bracket:

The level between the print head and the ink system has to be set accurately at
all times. Any height adjustments of the print head must always be carried out
together with the ink system.

The lower edge of the print head should be set higher as the lower edge of the
ink system. According to the drawings in the manual.

If the ink system is higher than the print head, the ink will leak from the head; if
the print head is installed too high, the surface tension of the ink at the nozzle
plate will be disturbed, causing air to enter.

As explained in the functional description, the print head should not be subjected
to impacts or vibrations. To ensure faultless operation, the print head should
therefore be protected against:

Impact and vibrations near the point of installation. It may be preferable to install
the print head and the ink system on a Multiline MX floor support (see appendix)
on the floor of the hall.

The product itself! Lateral guides must reliably prevent the material to be printed
(e.g. the front edge of a cartons) to come into contact with the print head, which
could result in impacts (causing air bubbles in the system) or even damage to the
nozzle plate.
Installation must be performed by specialised staff:
1. Install the mounting bracket on the production line.
2. Push the print head with the clamp on the bottom or into the mounting bracket.
3. Set the distance between the print head and the product surface. A distance of 0 to 4 mm
is optimal (see page 73 Fig. 25).
4. Connect the print head cable to the connecting socket of the print head and tighten.
5. Connect the photo sensor cable to the connecting socket of the photo sensor and tighten.
6. Mount the light barrier to the print head in such a way that the product to be printed
passes the light barrier before passing the print head. The photo cell should have an
unlimited view to the product (send- and reception diode). Tighten the screws only to the
extent that the plastic enclosure will not be damaged. Alternatively, another sensor may
be used.
7. Mount optional rotary encoder on production line.
8. Connect the rotary encoder cable to the rotary encoder connector and fasten.
9. If necessary, mount an additional screen to protect the print head.
10. Check data of the public power supply with the technical data of the power supply.
 Chapter Technical data, Page 20 Take the electrical connection by correlation only!
11. Put the power plug in an isolated ground receptacle.
12. Put the ink bottle in the fixing.
To avoid faults caused by potential differences, the print head must be electrically
connected to the conveyor belt.
13. When laying, ensure that cables are not tripping hazards and do not lay them around
corners and sharp edges. Avoid abrasive surfaces.
