Xerox 7760 gear & 04-376 errors

Hi all

I'm looking for the part number for the White gear in the center of the attached picture.

It is located in the at the rear upper side of the printer above the Fuser and it drives the left door inverter I think.

I can't see it listed in the manual so assume it's part of an assembly.

I also have many 04-376 errors in the log with strange printing.

Can anyone help?

Thanks!

007K88114 Drive Assy - Main FT this may be it...maybe..also a bigger pic of the area would really help to get a idea of gear location..the drawings in the ser man are not really helpfull

004-376 Zero Crossing Signal Not Detected

The zero crossing signal is not detected.

Procedure

Check that J590 on the AC Drive PWB (

PL 9.2) is securely connected.Check that J412 on the Engine Control Board (MCU PWB) (PL 13.1) is securely connected.Check the condition of the wires between J590 and J412 (Figure 1). The connections andwires are good.Y N

Repair as required.Measure the voltage at 590-1 on the AC Drive PWB (pin 1 is toward inside of machine). Checkfor both DC and AC voltages of 0.44 VDC and 0.92 VAC (

Figure 1). The voltage measuresapproximately 0.5 VDC and 1 VAC.Y N

Measure the voltage at J590-7 (pin 1 is toward inside of machine) for +5 VDC.

The voltagemeasures +5 VDC.Y N

The wires were previously checked. Replace the Engine Control Board) (MCU PWB(

PL 13.1).Measure the voltage at J590-5 (pin 1 is toward inside of machine) for less than +1 VDC.

The voltage measures less than 1 VDC.Y N

The wires were previously checked. Replace the Engine Control Board (MCU PWB)(

PL 13.1).Replace the AC Drive PWB (PL 9.2).Measure the voltage at J412-19 on the Engine Control Board (MCU PWB). The voltage measuresless than 1 VDC.Y N

Repair the open circuit between J590-1 on the AC Drive PWB and J412-19 on the ControlBoard (MCU PWB).

Replace the Engine Control Board (MCU PWB) (PL 13.1).
