Voltage Measurement and Specifications, Health and
Revision - Xerox Internal Use Only
Introduction
Voltage Measurement and Specifications
Measurements of DC voltage must be made with reference to the specified DC Common,
unless some other point is referenced in a diagnostic procedure. All measurements of AC volt-
age should be made with respect to the adjacent return or ACN wire.
Logic Voltage Levels
Measurements of logic levels must be made with reference to the specified DC Common,
unless some other point is referenced in a diagnostic procedure.
DC Voltage Measurement in RAPs
The RAPs have been designed so that when it is required to use the DMM to measure a DC
voltage, the first test point listed is the location for the red (+) meter lead and the second test
point is the location for the black meter lead. For example, the following statement may be
found in a RAP.
There is +5 VDC from P/J7 to P/J68.
In this example, the red meter lead would be placed on P/J7 and the black lead on P/J68.
If a second test point is not given, it is assumed that the black meter lead may be attached to
chassis ground.
Health and Safety Incident reporting
I. Summary
This section defines requirements for notification of health and safety incidents involving Xerox
products (equipment and materials) at customer locations.
II. Scope
Xerox Corporation and subsidiaries worldwide.
III. Objective
To enable prompt resolution of health and safety incidents involving Xerox products and to
ensure Xerox regulatory compliance.
IV. Definitions
Incident:
An event or condition occurring in a customer account that has resulted in injury, illness or
property damage. Examples of incidents include machine fires, smoke generation, physical
injury to an operator or service representative. Alleged events and product conditions are
included in this definition.
V. Requirements
Initial Report:
1. Xerox organizations shall establish a process for individuals to report product incidents to
Xerox Environment Health & Safety within 24 hours of becoming aware of the event.
2. The information to be provided at the time of reporting is contained in Appendix A (Health
and Safety Incident Report involving a Xerox product).
3. The initial notification may be made by any of the following methods:
• For incidents in North America and Developing Markets West (Brazil, Mexico, Latin
American North and Latin American South):
– Phone* Xerox EH&S at: 1-800-828-6571.
– Electronic mail Xerox EH&S at: Doris.Bush@xerox.com.
– Fax Xerox EH&S at: 1-585-422-6449 [intelnet 8*222 6449].
• For incidents in Europe and Developing Markets East (Middle East, Africa, India,
China and Hong Kong):
– Phone* Xerox EH&S at: +44 (0) 1707 353434.
– Electronic mail Xerox EH&S at: Elaine.Grange@xerox.com.
– Fax Xerox EH&S at: +44 (0) 1707 353914 [intelnet 8*668 3914].
*Initial notification made by phone must be followed within 24 hours by a completed inci-
dent report and sent to the indicated electronic mail address or fax number.
NOTE: If sending a fax, please also send the original via internal mail.
