Chapter 4 - Working System of Flora PP 2512UV
4.1 Brief Introduction
The Flora PP 2512UV large format printer is using raster image technology to process photos
stored in computer. It is one of the most innovative products, which combines photo digital technology
with high precision engine driver. It produces super wide printouts for business use.
It is a high technology equipment with a user friendly operating system with simple operational
and maintenance procedures. Though simple, it is composed of several precise systems. In this chapter,
we will introduce the system components and operator guide.
4.2 The Konica Minolta Print head Assembly
In a high quality and high performance configuration, Konica Print head offers a high-resolution,
high-speed and compact inkjet print head lineup suitable for both wide format and industrial applications.
Konica Minolta print heads are based on piezo-electric materials (PZT), in which can be made to
move by applying an electric field across it. Ink channels composed of piezo walls can eject small drops
of ink in accordance with the electrical signals applied to the electrodes on the walls.
The KM512 Print Head is driven by “shear mode”, in which the walls bend inward and outward to
generate a pressure wave inside the channel. This mechanical ejection principle allows a wide range of
inks including oil and solvents, which is a great advantage when compared with the thermal ejection
inkjet head.
This section introduces the KM512 Print Head technologies.
