Perform the following steps tocheck that the ballast resistor circuit is operating correctly:1. Disconnect the BRN wire from A1Q1-G.2. Set the meter to read 60 VAC (USO) or 120 VAC (XR).3. Connect the (+) meter lead to A1Q1-MT2 (BLU wires).4. Connect the (-) meter lead to A1Q1-MT1 (WHT wires).5. Connect the Power Cord and switch on the printer.At least 60 VAC (USO) or 120 VAC (RX) is present.Y NSwitch off the printer and disconnect the power cord. Set the meter to read 8 to 21ohms of resistance. Disconnect the wires on each Ballast Resistor, A1R1 andA1R2R2, before measuring the resistance. The resistance of each Ballast Resis-tor, A1R1 and A1R2, is 7 to 9 ohms (USO) or 19 to 21 ohms (RX)Y NReplace both Ballast Resistors, A1R1 and A1R2, PL 1.2A.Check the following Ballast Resistor wires for continuity;The wires have continuity.Y NRepair the wires.Set the meter to read +26 VDC. Connect the (+) meter lead to the Fuser BallastPower Relay. A1K3-1. Connect the (-) meter lead to A1K3-0. Reconnect the PowerCord and switch on the printer. There is +26 VDC present for approximately 5seconds.Y NConnect the (+) meter lead to A2P213-6. Connect the (-) meter lead toA2P213-7. Reconnect the Power Cord and switch on the printer. There is +26VDC present for approximately 5 seconds.Y NReplace the Driver PWB, A2, PL 1.1A.Repair the wires.Replace the Ballast Relay, A1K3, PL 1.2A.Replace the Heat Rod Control PWB PL 1.2A.Table 1 Ballast Resistor WiresFrom To ColorA1R1-1 A1K3-8 REDA1R1-2A A1Q1-B BLUA1R2-1 A1K3-4 REDA1R2-2A A1R1-2B BLUAABBCCDD
