section A); values greater than 12.0 volts lead to more severe problems including
premature cartridge failures and severe banding.
2. Verify Proper Receptacle Configuration:
Verify the regional power (source) receptacle has a Ground
(G) line for the respective region (N is neutral; L is line or hot).
CAUTION:
If receptacle does not have a ground line (2-prong
outlet only) then immediately stop using the printer. The printer
is extremely dangerous to operate in this configuration (with
power applied) and is a personnel hazard. The problem, for the symptoms
described in section A, cannot be fully corrected until the electrical system/receptacle is
properly fixed. Inform the customer a certified electrician will need to be contacted to
upgrade the electrical system with a properly grounded outlet.
Do not operate/work on printer if a 3-prong to 2-prong adapter, non-
grounded standard receptacle, non-grounded GFCI receptacle, or a
'separate' ground line runs from the printer. Contact technical
support management if necessary for intervention/assistance.
3. Testing Receptacle Neutral-to-Ground Voltage:
- In North America the easiest and safest test method is to use a
receptacle tester (i.e. available at Home Depot) to determine proper
outlet polarity and grounding. Simply plug the device into the outlet
(standard and GFCI outlets), typically two LEDs (of the same color)
should illuminate indicating proper electrical configuration.
- In all other countries a voltmeter may be used for test
purposes. Verify the voltage level between Ground and Neutral
is correct (normally <2.0 volts AC). A 'voltage screwdriver' may
be used to easily test for the presence of voltage (phase) on
ground and neutral lines (LED illuminates).
NOTE:
neutral and line may be reversed in many European countries.
