Diagnostics information 2-27Operator panel service checkInspect the operator panel cable for damage. Make sure the cable is plugged in securely. Run POST, and checkeach light for proper operation. See “Power–On Self Test (POST) sequence” on page 2-1.Paper feed service checksPaper jam error indication during POSTMedia picks but stops halfway through the printerLCD Operator panel service checkFRU ActionOperator panel (LCD)Controller boardWarning: Do notreplace the operatorpanel and controllerboard at the sametime. Each cardcontains the printersettings. When eitherof these cards is new,it obtains the settingsfrom the other card.Settings are lost whenboth are new andreplaced at the sametime.LightsIf the LCD does not come on, then open the controller board cage and locate the operatorpanel connector at J3. Make sure the cable is properly connected to the controller boardand the controller board has input voltage to it.With the printer on, verify the following without disconnecting the cable:• Pins 1, 3, 5, and 6: 3.3 v• Pin 2: 5 v• Pins 4 and 7: GNDIf these are approximately correct and the operator panel is not functioning, then replacethe operator panel.If any are incorrect, then see “Controller board service check” on page 2-22.ButtonsIf the buttons do not respond, then replace the operator panel. There is no test or repair forthe faulty switches on the operator panel.FRU ActionFuser (exit sensor) If the exit sensor flag, which is visible at the back of the fuser, is in any position other thanvertical, then the printer will display a paper jam. Make sure the flag is operating freely.Replace the fuser if the sensor is damaged.Input/duplex sensorManual feed sensor Make sure the input paper feed sensors are working properly. A stuck or incorrectly installedsensor causes a paper jam indication.FRU ActionInput/duplex sensors(under print cartridge assembly)Input sensor (manual)Make sure the input sensors are working properly.Check for a broken or stuck flag on the input sensors. Clear anything that keepsthe flags from rotating freely.Make sure the cables are seated on the controller board at J27 (input/duplexsensor) and J23 (manual input).Check for +5 V dc on pin 2 and 5 at J27 (input/duplex sensors) and pin 2 at J23(Input sensor). Voltages on pins 1 and 4 at J27 pin 1 at &23 should change as theflags intersect with the sensor.• If correct, then replace the input paper feed sensor.• If these voltages are not correct, then replace the controller board.• Check the pick tires. Clean or replace as necessary.
