Phaser 4400 Laser Printer Service Manual 3-3AC Power Testing ProcedureStep Actions and Questions Yes No1for[115VAC]1. Disconnect the AC power cord from the wall outlet.2. Measure the AC voltage between AC Line andNeutral, between AC Line and Ground, and betweenAC Neutral and Ground.3. The voltage between Line and Neutral and betweenLine and Ground should range from 90 to 140 VACand the voltage between Neutral and Ground shouldbe less than 3 VAC.Is the AC voltage within specification?Go to step 4 Informcustomer ofinsufficientvoltage orimproperwiring.1for[220VAC]1. Disconnect the AC power cord from the wall outlet.2. Measure the AC voltage between Line and Neutral,between AC Line and Earth/Ground, and betweenNeutral and Earth/Ground.3. The voltage between Line and Neutral and betweenLine and Earth/Ground should range from 198 to 264VAC and the voltage between Neutral and Groundshould be less than 3 VAC.Is the AC line voltage within specification?Go to step 2. Informcustomer ofinsufficientvoltage orimproperwiring.1for[220VAC]1. Disconnect the AC power cord from the wall outlet.2. Measure the AC voltage between Line and Neutral,between AC Line and Earth/Ground, and betweenNeutral and Earth/Ground.3. The voltage between Line and Neutral and betweenLine and Earth/Ground should range from 198 to 264VAC and the voltage between Neutral and Groundshould be less than 3 VAC.Is the AC line voltage within specification?Go to step 2. Informcustomer ofinsufficientvoltage orimproperwiring.2 1. Check the continuity through all connections of thepower cord.2. The measurement should be less than 10 ohms foreach connection.Does continuity test per specification?Perform ìDCPower(LVPS)îReplace thepower cord(ìPL 10.1Electricalî).
