EC-JET 1000Pro Continuous Inkjet Printer
2.2 System Description
The EC-JET printers are designed to provide versatile, uninterrupted operation in factory environments.
The models available, together with available raster types and compatible print heads are as follows:
2.2.1 Operating Simplicity
Easy start-up and shutdown requires minimal operator intervention. Messages are easily created using
the built-in QWERTY keyboard, and the printer offers print adjustment and message editing facilities.
2.2.2 Diagnostics
A comprehensive diagnostics package is built into the printer to enable problems to be identified and
rectified quickly.
2.2.3 Print head Design
The print head is robustly designed for industrial environments. It is hermetically sealed and is
permanently attached to the printer itself by a 2 metres length of conduit.
2.2.4 Printing Drops
To form a printed pattern, each drop must be directed to a different place on the product being printed.
To achieve this, the drops pass through a charge electrode (within the print head), which applies a
different charge to each drop. This causes the flight path of the drops to differ as they travel between
two deflector plates. When the drops reach the product, they form one line of drops called a raster. As the
product passes under the print head, rasters are laid down side by side to form the printed message.
2.2.5 Leaving Gaps
Unprinted drops in a raster carry no charge and are therefore not deflected. These drops are captured by
a gutter in the print head, and returned to the ink tank. Gaps between raster (perhaps to separate
