Xerox Phaser 7500 077-900 error
I have a Xerox Phaser 7500 that starts printing from tray 2 and jams every time. It gives me an error 077-900. I have checked the Xerox website but I cannot find any documentation on what is causing this error code.
The code stands for "Registration Sensor Static Jam"
Most likely culprit is a torn piece of paper blocking the registration sensor.
If there is no blockage of the registration sensor, then run sensor diagnostics and check status
of sensors. Replace sensor if diagnostics show it closed when it should be open.

I have seen a very small piece of paper stuck in the track. I had to bascially disassemble the printer to be able to see it. Also, have you tried changing the pickup rollers (or try cleaning them with alcohol as a test). It could be that the paper doesn't reach the sensor in time because there is a pick problem. This is all set on time the sensor expects to see the leading edge of the paper.

Do you know where I can get a diagram showing where the sensor is and pickup rollers.
Unfortunately not. Xerox seems to keep all of the tight under wraps. I have even had trouble getting part since they typically only sell to "authorized service providers". Since I have worked on printers for nearly 20 years, I usually just start disassembling them carefully until I get to that area. A flashlight also helps in looking into the path. I have been able to either tell there was a small piece of paper before getting too far in, or been able to see that there was and work at getting it out.
Okay the part number for the sensor is #930W00111.
If you send me your email I can send you the parts diagram showing where the sensor is.
