10/002-47Phaser 790/DocuColor 2006 004-320Status Indicator RAPsInitial Issue004-320 Paper Handling Motor RAPThe Control Logic detected that the Paper Handling Motor is not functioning.Initial ActionsCheck the connectors on the Drive Motor PWB. Ensure that they are correctly seated.ProcedureSwitch off the power then switch on the power. The 04-320 fault code is declared at the endof self-test.Y NGo to Flag 2 and check the harness between the Drive Motor PWB and the Paper Han-dling Motor for damaged wires or connector pins. If the wires are OK, replace the PaperHandling Motor (PL 10.1). If the problem continues, replace the Drive Motor PWB (PL10.1).Access the Digital Output (DO) test from the Control Panel. Enter code [53]. Press the Item/Enter button. The Paper Handling Motor energizes.Y NAccess the DO Stop Test from the Control Panel. Enter code [53]. Press the Item/Enterbutton. +5 VDC is measured between J50-2 on the Drive Motor PWB and machineframe.Y NGo to Flag 3 and check the wires for an open circuit. If the wires are good, replacethe MCU PWB (PL 11.2).Access the Digital Output (DO) test from the Control Panel. Enter code [53]. Press theItem/Enter button. The voltage at J50-2 goes to less than +1.0 VDCY NReplace the MCU PWB (PL 11.2).+24 VDC is measured between J49-2 on the Drive Motor PWB and machine frame.Y NGo to Flag 4 and check the wires for an open circuit (refer to the +24 VDC Inter-locked Wirenet).Go to Flag 2 and check the harness between the Drive Motor PWB and the Paper Han-dling Motor for damaged wires or connector pins. If the wires are OK, replace the PaperHandling Motor (PL 10.1). If the problem continues, replace the Drive Motor PWB (PL10.1). If the problem can not be resolved, replace the MCU PWB (PL 11.1)Check the following:• Go to Flag 1 and check the wire for an open circuit.• Go to Flag 2 and check the harness between the Drive Motor PWB and the Paper Han-dling Motor for damaged wires or connector pins.• The problem may be intermittent. Go to Figure 1 and check for loose or damaged connec-tions or damaged wires. If the problem persists, replace the replace the MCU PWB (PL11.2).
