movement generates the pressure wave in the ink. This pressure wave forces ink out of the end of the
channels via the printhead's nozzle.
Shear mode is more efficient than the direct mode of printing employed by other inkjet technologies as it
effects a greater deformation in the piezoelectric material without using more energy.
3.3 Ink system
Fig. 3.2
Printhead and ink levels
The printhead acts like a pump and therefore is capable of pulling ink through it. A negative ink supply
pressure must be used for the printhead to operate properly.
The most common and most simple way to supply a negative pressure ink supply is to position the ink
reservoir below that of the printhead nozzles. The ink reservoir is open to atmospheric pressure.
The orientation of the printhead is between horizontal, as in Fig. 3.2, and vertical position, see section 6.3.
The vertical orientation is only used for printing downwards. Upwards printing is not possible due to the
very high risk of clogging the nozzles.
It is important that for any orientation of the printhead the top ink level is at least 3mm below the level of the
first (bottom) nozzle, otherwise the printhead starts ‘bleeding’ ink.
3.4
Spit function
In extreme cases, it is necessary to enable the spit timer. This timer triggers the printhead to spit ink through
all the nozzles and in this way prevents clogging of the nozzles.
The disadvantage of using the spiting timer is waste of ink and probably the need of a device that collects
the ink while spitting. Refer to chapter 7.5.1 Setting the spit parameters for further information.
3.5 User interface
The user interface on the control unit consists of a capacitive touch panel displaying the menu structure of
operator menus.
The touch panel consists of a capacitive touch screen and a TFT panel. The screen can also be operated with
gloves on (supplied with the ink). A stylus for capacitive touc screens can also be used if required.
