AC Power Testing Procedure Step Actions and Questions 1 for [115 VAC] 1. Disconnect the AC power cord from the wall outlet. Yes No Go to step 4 Inform customer of insufficient voltage or improper wiring. 1 for [220 VAC] 2. Measure the AC voltage between AC Line and Neutral, between AC Line and Ground, and between AC Neutral and Ground. 3. The voltage between Line and Neutral and between Line and Ground should range from 90 to 140 VAC and the voltage between Neutral and Ground should be less than 3 VAC. Is the AC voltage within specification? 1. Disconnect the AC power cord from the wall outlet. Go to step 2. Inform customer of insufficient voltage or improper wiring. 2. Measure the AC voltage between Line and Neutral, between AC Line and Earth/Ground, and between Neutral and Earth/Ground. 3. The voltage between Line and Neutral and between Line and Earth/Ground should range from 198 to 264 VAC and the voltage between Neutral and Ground should be less than 3 VAC. Is the AC line voltage within specification? 1 for [220 VAC] 1. Disconnect the AC power cord from the wall outlet. Go to step 2. Inform customer of insufficient voltage or improper wiring. 2. Measure the AC voltage between Line and Neutral, between AC Line and Earth/Ground, and between Neutral and Earth/Ground. 3. The voltage between Line and Neutral and between Line and Earth/Ground should range from 198 to 264 VAC and the voltage between Neutral and Ground should be less than 3 VAC. Is the AC line voltage within specification? 2 1. Check the continuity through all connections of the Perform "DC Replace the power cord. Power power cord 2. The measurement should be less than 10 ohms for each connection. (LVPS)" ("PL 10.1 Electrical"). Does continuity test per specification? Phaser 4400 Laser Printer Service Manual 3-3
