02/20002-27DocuPrint N2125 RAP 24Status Indicator Repair Analysis ProceduresInitial IssueRAP 24 Inoperative PrinterThe main power cannot be switched on.ProcedureEnsure the power cord is properly connected to the wall outlet and to the Power Receptacle ofthe printer. The problem still exists.Y NProblem solved.Perform RAP 1, then return here. RAP 1 indicated that correct AC voltage is being sup-plied to the printer.Y NNotify customer that the power is out of specification.Perform RAP 2, then return here. RAP 2 indicated that correct DC voltage is being sup-plied to the printer.Y NRap 2 instructed you to replace a component.Y NPerform RAP 3.Replace component as necessary.On the System Controller PWB, check the voltage on P/J13 between pins 1 and 2. The volt-age is 3.3VDC.Y NSwitch the printer power off. Disconnect P/J13 from the System Controller PWB. Switchthe printer power on. Check the voltage between pins 1 and 2 on the disconnected plug.The voltage is 3.3VDC.Y NReplace the LVPS (REP 9.5).Switch the printer power off. Remove any options connected to the System ControllerPWB. Reconnect P/J13 to the System Controller PWB. Switch the printer power on.Check the voltage on P/J13 between pins 1 and 2 (if there are no options installed, followthe No path). The voltage is 3.3VDC.Y NReplace the System Controller PWB (REP 9.2).Switch the printer power off. Reinstall the removed options one at a time, switching on thepower and checking for 3.3VDC on P/J13 between pins 1 and 2 after each one isinstalled. Replace the option just installed when the voltage fails.On the System Controller PWB, check the voltage on P/J13 between pins 3 and 4. The volt-age is 5.0VDC.Y NSwitch the printer power off. Disconnect P/J13 from the System Controller PWB. Switchthe printer power on. Check the voltage between pins 3 and 4 on the disconnected plug.The voltage is 5.0VDC.Y NOn the LVPS, check the voltage between P/J PN1 pin 1 and frame ground. Thevoltage is +24.0VDC.Y NReplace the LVPS (REP 9.5).Replace the System Controller +5.0VDC Power Supply (REP 9.4).Switch the printer power off. Remove any options connected to the System ControllerPWB. Reconnect P/J13 to the System Controller PWB. Switch the printer power on.Check the voltage on P/J13 between pin 3 and frame ground (if there are no optionsinstalled, follow the No path). The voltage is 5.0VDC.Y NReplace the System Controller PWB (REP 9.2).Switch the printer power off. Reinstall the removed options one at a time, switching on thepower and checking for 5.0VDC on P/J13 between pin 3 and frame ground after each oneis installed. Replace the option just installed when the voltage fails.On the Print Engine Controller PWB, check the voltage between P/J28 pin 1 and frame ground,P/J28 pin 7 and frame ground, and P/J28 pin 10 and frame ground. The voltage on pin 1 is+24VDC, pin 7 is +5.0VDC, and pin 10 is 3.3VDC. All voltages are correct.Y NReplace the LVPS (REP 9.5).Replace the System Controller PWB (REP 9.2). If the problem persists, replace the PrintEngine Controller PWB (REP 9.3).AAmanuals4you.commanuals4you.com
