LSU error message

Remove the jammed paper. Unplug the printer from the mains and PC. Inspect the rollers, etc for tiny paper piece(s) that may be stuck, or other debris. Try to clean rollers and make sure they are dry.
Keep printer unplugged for about 2 minutes and replug and try a test print.
Also make sure that you have waited long enough for the printer to heat up before giving a print job.
Finally, it could be an issue with the paper sensor. If this is the case, you will probably have to take the printer in for servicing..

Xerox Phaser 8500DN printer error : 09,037.45:67244


35 = Cyan
36 = Magenta
37 = Yellow
38 = Black

The error indicates an ink stick was jammed. You have to clear the ISC (ink stick count) error.

Turn off the printer.
Turn on the printer.
As soon as you see XEROX start moving across the display hold down the back and help buttons until you see "beginning service mode" on the display.
Release the buttons, it will now come up in the service mode.
Scroll down to the function menu, hit ok, scoll to clear isc faault, hit ok.
Hit the back button to get back to the first menu then exit diagnostics, hit ok when it asks if you want to restart in customer mode.

Error code

I believe your error message is "Open Heat Error". If that's the case, your fuser unit is bad. I understand that it is a new unit, although you do no specify if is is brand new or refurbished.

Now see, the open heat error comes when the temperature sensors on fuser detect a higher temperature than normal. I f that's the case you can easily confirm that by opening the side door (as if changing the toner) and feeling the intense heat coming out. If the fuser was new, then most probably you got a bad power supply board.

This is truly bad news, because for the power supply board to get damaged, a voltage surge must have ocurred. In most cases, there is also a need to replace the main board as well, for the copier starts working erratically, and loses some of its functions (such as duplex copying).

If the unit is under warranty, call Xerox. If you plan to get it repaired, or fixed by yourself, you can buy cheaper Samsung parts, for Samsung is the real manufacturer of the unit. The Samsung model is SCX-5115 gor a non fax unit, and SCX-5315f for a fax capable unit.

Good luck.

By the way, if you happen to fix the copier, or buy a new one, the only way to TRULY protect it from voltage damage is with an Innovolt SVSS protector. This is truly new protection technology and we sell them a lot here in Puerto Rico. Price is $74.95 plus shipping.
