KODAK 1200i WIDE-FORMAT PRINTING SYSTEM

CAUTION: if neutral-to-ground voltage, above 6 volts AC, is present then a serious problem is present within the building's electrical system. Often a mis-wired connection or imbalanced phase load can cause

voltage/current to ‘bleed’ onto the ground line (commonly referred to as neutral-to-ground voltage) or a serious ground fault exists within the building. Immediately stop service on the printer. The printer is extremely dangerous to work on in this condition (with power applied) and is a personnel hazard. The problem, for the symptoms described in section A, cannot be fully diagnosed and/or 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 or to correct a neutral-to-ground voltage problem.

D. Power/Voltage Testers

1.In North America, basic receptacle testers are available for testing standard 110 volt receptacle/wall outlets for proper polarity and ground detection. These models are probably the fastest way in detecting improper wiring or the presence of a ground fault.

The three LEDs help the electrician or technician identify:

Correct wiring

Hot/neutral reverse

Hot/ground reverse

Missing neutral

Missing ground

Missing hot.

2.In other continents a simple voltage ‘screwdriver’ may be used, such as the inexpensive Stanley 3MM Voltage Tester. These tools are used to determine the presence of phase on a hot line (L), neutral (N) or even ground (G).

3.The universal test instrument is the voltmeter or multimeter which may be used to measure dc, ac, resistance, etc.
