August 20072-246 WorkCentre 5687 Family09-370Status Indicator RAPs09-370 Developer Temperature Sensor Failure RAP09-370 The average developer temperature reading is out of limits.Initial ActionsSwitch off the machine, then switch on the machine, GP 14.ProcedureEnter dC330 code 09-370, developer temperature sensor Q09-370. Press start. Observe thedisplayed state of Q09-370. Remove the xerographic module. Disconnect P/J47, Figure 1.Cheat the front door interlock. Observe again the displayed state of Q09-370. The displayedstate has changed.Y NGo to Flag 1. Check for +5V at P/J7 pin 5 on the IOT PWB. +5V is present.Y NGo to the 01E +5V Distribution RAP.Go to Flag 1. Check for +5V at P/J47 pin 3. +5V is present.Y NNOTE: To gain access to the wiring, remove the main drive module, (32-55 ppm) PL4.15 Item 1, (65-87 ppm) PL 4.10 Item 1 and the left hand cover, PL 8.10 Item 3.Check the wiring between P/J7 on the IOT PWB and P/J47. Repair the wiring asnecessary, REP 1.2.Install a new temperature sensor, (32-38 ppm) PL 9.22 Item 5, (45-87 ppm) PL 9.20 Item5.If the fault persists. Perform OF7 IOT PWB Diagnostics RAP before a new IOT PWB isinstalled, PL 1.10 Item 2.Q09-370 is working correctly. Reconnect P/J47.If the fault is intermittent, perform the steps that follow:• Check the wiring, GP 7. Repair if necessary, REP 1.2.• Make sure that the P/Js are correctly and securely connected.Figure 1 Component LocationFigure 2 Circuit diagramTemperature sensorQ09-370P/J47
