Introduction
Service Manual Notes
This manual is based on an OEM original. Some part names used do not comply with the standard
Xerox part naming convention. Because part names may have been molded on to some plastic
components and may also be embedded in the software, the part names have not been changed.
To aid part identification, an acronym and abbreviation list
GP 48 has been added.
Safety Precautions
IMPORTANT
1. The FaxCentre F110 has been specified as a Class I Unit (earthed/grounded). The Telecom
Line potential is isolated from the digital circuitry. To measure on the digital side, the meas-
urement equipment should be connected to the same earth (ground). For measurement on
the Telecom side, measurement equipment should be unearthed (ungrounded).
2. After each disassembly of the apparatus the same safety tests as in the production line have
to be performed (see GP 47 SAFETY-Test Specification”). These tests include four different
steps to guarantee safety of the product according IEC /EN 60950-1:2001
Test procedure:
a) Earth (Ground)-Continuity Test
b) Isolation Test
c) High Voltage Test: Primary/AC Power – Secondary (USB)
d) High Voltage Test: Primary/AC Power – Telephone line
WARNING
Switch off the electricity to the machine. Disconnect the power cord from the customer supply
while performing tasks that do not need electricity. Electricity can cause death or injury. Moving
parts can cause injury. Never remove the isolation plate from the PSU.
