4. Install Ant-Static Mats (3
party)
- The installation of Anti-Static mats below the printer have
been known to efficiently control/minimize ESD levels
between personnel and the printer.

C. Printer/Receptacle Power Tests
If the ESD Control Measures (above) have been installed and ESD symptoms continue
to exist with printer operation it is suggested to check for proper printer/receptacle power
and adequate grounding. Below are some suggested test methods for both the printer
and the incoming power source.
Only properly trained service technicians should attempt to perform Step 1 below.
It is strongly suggested to contact a certified electrician if a test method or
measured value is not completely understood.
1. Testing AC level on printer chassis:
- Turn on Printer. With meter in an AC scale, connect both the black and red leads to the
printer's rear metal plate screws at rear of printer. The normal chassis AC voltage
reading, with proper electrical wiring/grounding in place, should be between 0.0 and 0.4
volts AC. Any level higher than 2 volts AC indicates a ground or neutral line problem is
present (ground fault or floating ground).
NOTE:
Typically
anything below 4.5
volts AC will not
cause a problem
with printed output,
but this largely
depends on
humidity level and
ESD level of
media.
Values
higher than 8.0 volts AC will start to cause some problems with image output (refer to
