using Xerox parts or clones, fuser and cartridges./

you may be pressing the buton to many times just pres it once or if that is not the problem then your printer may need to be checked by a repearer

That's normal for any printer. It's trying to pick up the printing of the entire document.
If it didn't print the same page again after you clear the jam, you would be missing a page.

Paper jams can be tricky to solve. The paper is usually stuck inside the printer mechanism so even if there is no visible paper jam, you will still get the paper jam error. Try this:

1. Turn off your printer
2. Open all trays and remove any paper stuck there
3. Locate the button to open the printer, open it and remove any paper stuck there also.
4. Repeate the above step for all buttons that you can find to access the inside of the printer
5. Close all doors and put back all trays
6. Turn on your printer

pull out the paper drawer and look on the ceiling of the compartment. you will see a little orange rubber roller that should be clicked inplace. it feeds the paper up into the roller. also, the drawer itself contains two sensors. if you go to the xerox page you can download the pdf that lists all the parts and the errors and how to disassemble the whole thing. i have the same printer and got a print head error and a paper jam that required complete disassembly. feel free to email me for additional help.

remove the belt and clean

These errors are usually caused by a cracked DM Camshaft (Drum Maintenance). This was a very common problem for Xerox, they usually broke while under warranty, but there a heck of a lot out there that are just now going bad after a year.

You may or may not need to replace the "Motor Process Drive Gears" as well as the DM camshaft.

You might be able to talk Xerox into doing this as a warranty repair, if you ***** real loud.

The fuser exit sensor had an updated version for that model (old model has a "bounce" problem). Xerox gives a 1 year warranty..I would get them out to fix it pronto !

It is also helpful to have the error code. Press the i button while the printer has the jam message on the front panel. Use the fault code to locate where the jam actually is. (This will help the technician greatly ! )

Sounds like printhead needs replacement.
Moving these printers without cool down is known to destroy printheads and of course wax goes everywhere and then everything else fails.Think about replacement

There is a flag sensor on the registration assembly that is possibly broken.
