UF-5500 / 4500 11.2. Troubleshooting Details 11.2.1. Initialization There are two types of initialization, one is the short initialization (about 3 seconds) and the other is the long initialization (about 10 seconds). The short initialization makes the unit enter the standby mode. The long initialization makes the unit enter the standby mode after cleaning or detecting the rest of toner.

If rotation sound isn't heard, check 24V line, POLON signal and POLCLK signal. If even a little of sound is heard, check XREADY signal.
Page 131 UF-5500 / 4500 11.2.3.2. INFO CODE=054 "INFO CODE=054" means that the synchronous signal out of the LSU cannot be detected. The synchronous signal out of the LSU is detected by IC 300-G23pin (NHSYNC). After the LCD indicates "INFO CODE=054 ", turn the power OFF/ON, then confirm the waveform when the unit starts initial operation.

Page 240: Exposing
UF-5500 / 4500 13.2.3. Exposing When the drum which is charged with the fixed electric charge is irradiated by the laser beam, the plus charge and minus charge are generated at the Charge Generation Transfer Layer. Passing through the Charge Generation Transfer Layer which conducts the minus charge, the plus-charged drum's surface is neutralized to be skipped.
Page 241: Developing And Transcription
UF-5500 / 4500 13.2.4. Developing and Transcription The developing is the stage that the OPC drum with an invisible image is changed to visible by the toner. The drum cartridge con- sists of mixing paddle, toner supply roller, developing roller, developing blade, charge wire, grid plate and OPC drum. The bias volt- age is added to the developing roller and toner supply roller.
Page 242: Cleaning Of Transfer Roller
UF-5500 / 4500 13.2.5. Cleaning of Transfer Roller The toner attached to the surface of the OPC drum is transferred to the paper at the transcription stage, but a part of the toner remains. The cleaning is the stage that cleans the remain toner after the transcription stage. The remain toner on the drum and the toner which was attached to the place where the laser beam didn't scan are gathered to the developing roller to be used again.
Page 243: Fixing
UF-5500 / 4500 13.2.6. Fixing On the process of the transfer, the transferred toner is weakly attached on the paper. Fixing means the process to fix the toner on the paper permanently. The fixing part melts the toner at the high temperature using the halogen heater. The toner is fixed on the paper by the heat and pressure through the fixing part with the image.
