Phaser 6180MFP Multifunction Printer Service Manual 4-15General TroubleshootingMAC+PHY Test MAC+PHY Test■ Start■ Processing■ Check OK■ MAC+PHY ERRORTests PHY Internal loopback test.Note: Run this test when errors 016-334, 016-340, 016-344, 016-345, 016-346, and 016-347 occur.ASIC Test ASIC Test■ Start■ Check OK■ ASIC ERRORPerforms register test.Note: Run this test when error 116-343occurs.Engine Test Engine Test■ Start■ Check OK■ Engine ERRORPerforms communication test with theEngine Controller. Then it reads thestatus register of the engine to checkwhether commands can be exchangedwith the engine.Note: Run this test when error 016-370occurs.Engine Diag Performs function checks on the components whether theyoperate normally or not.Note: During Engine Diag test, other Service Diagnostics functionscannot be performed simultaneously.Sensor Test Tests the sensors and switches of theprinter.When a paper jam is occurred, or anerror message or code is displayed,run this test to locate the damagecomponents.Note: The Low/High values can be 0 to99, and they can be incremented as thesensor state changes. This value isincremented up when a sensor orswitch is turned On from Off, whichallows the user to know the componentis active.Duplex JamSensorDuplex JamSensor■ OFF■ L - 0■ H - 0Tests the Duplex Jam Sensor.Exit Sensor Exit Sensor■ OFF■ L - 0■ H - 0Tests the Exit Sensor.Regi Sensor Regi Sensor■ OFF■ L - 0■ H - 0Tests the Registration Sensor.Printer Diag Test Table (continued)Test Control Panel Display Test Description
