6.3.7 Radial and axial printhead rotation
An application with a combined axial and radial printhead rotation is more difficult, because both graphs,
Fig. 6.13 and Fig. 6.16, cannot be combined. As described in section 3.3, it is important that for any
orientation of the printhead the top ink level in the reservoir is at least 3mm below the level of the first
(bottom) nozzle, otherwise the printhead starts ‘bleeding’ ink.
The top ink level lies 16.8 mm below datum-B if the reservoir is levelled. This means that datum-B lies 13.8
mm above the first (bottom) nozzle of the printhead. The distance between first (bottom) nozzle and the
bottom of the printhead housing is 15.4 mm.
To roughly set the ink level of the coding unit for a axial and radial printhead rotation:
1. Rotate the printhead housing so that the plane of the front-plate is positioned parallel to the
substrate and perpendicular to the direction of the product.
2. Position the printhead housing at the desired location. Datum-A is now fixed
3. Clamp with a cramp an aid-strip, levelled at 13.8 mm below datum-B, to the ink reservoir. The
topside of the aid-strip lies now 3 mm above the top ink level.
4. Position the aid-strip in the horizontal plane of the first nozzle while keeping the aid-strip and
reservoir level with the build-in leveller.
5. Mark the position of the ink reservoir.
6. Mount the ink reservoir at the marked position. Use, if necessary, extra clamps, poles or shafts.
7. Check whether the ink reservoir is levelled.
8.
Check with the aid-strip if the horizontal plane of the first nozzle is 13.8 mm below datum-B.
Beware:
After the first refill of the ink reservoir the printhead may start ‘bleeding’ ink. Stop this ‘bleeding’
by lowering the ink reservoir by about 1 mm.
