Reduce Static with the Static Suppression Option
Introduction
The Static Suppression Option (sometimes referred to as an Ionizer Bar) is a Commercial Product.
If you are experiencing static-related imaging problems this optional upgrade kit contains an
ionizer bar that provides a solution to reduce static. Some rigid media can have a large static
surface charge. If the charge is high enough, ink can be repelled from the media. This ink mist can
show up as cloudy areas in white sections of the image. Static not only causes these printing
artifacts, but can also result in excessive ink accumulation on the bottom of the carriage.
Purpose
Ionization is a solution to the problem of static. A common print industry method of controlling
static electricity is the use of ionization. For the anti-static bar to be effective, it must be close to
the media. The bar uses AC current to create positive and negative ions, which are attracted to
the unbalanced surface of the material. This neutralizes the media and ink is more readily
accepted. It is important to note that static electricity cannot be entirely eliminated; only reduced.
To eliminate static electricity, something physically would have to be done to the conductivity of
the material.
Humidity is also important to control static. Static-related print issues can be greatly reduced by
an increase in print environment humidity. While most media will print without difficulty at
humidity levels between 30 and 50%, thermoplastics will print more successfully when humidity
is above 40%. Some locales, such as desert areas frequently deal with very low humidity, while
other regions only experience this at certain times of the year. If a printer is installed in a low-
humidity area and/or a large volume of printed work is on media that is prone to static, we
recommend the installation of a humidity control system.
When to do
Why Static is a Problem
Many standard print materials such as PVC and acrylic are electrical insulators, and the static
charge generated and held by these materials can provide some printing challenges.
Thermoplastic materials are the most common static-laden print media. Static-prone materials
tend to attract dust and hair and release charges that can be felt and seen.
How to Activate the Static Suppression ionizing system
Procedure
1. Press the Settings tab on the printer interface screen.
2. Click on the Printer icon.
3. If the Ionizer Bar option is set to Off, set it to ON (this option is not displayed if the option is not
installed).
NOTE
Once you have set it to On, it will always automatically turn on at the beginning of a
flatbed job. Unless you use media that you are certain does not require static
reduction, there is no need to turn it Off as the bar is only active when the printer is
printing.
