Hi - I have a Xerox Workcentre 4250 Printer/Fax and keep getting error code 22-504 (Paper Properties Mismatch). The tray has the correct paper size ... what to do? All the pending jobs are idle ...

• Description: MSI Paper Size Mismatch Cause: The size of paper in the MSI does not match the specified print size.
• Remedy: 1. Open/close Tray, or reseat paper on manual feed tray. 2. Use the paper that meets the specifications. 3. Make sure that you are using the correct printer driver. 4. Check the Paper Size and Paper Type of the Tray Setting menu on the printer operator panel and the printer driver. 5. If the problem cannot be solved, replace the corresponding paper feed rolls. • MSI FEED ROLL / NUDGER ROLL (PL 2.6 MSI) • MSI RETARD ROLL (PL 2.7 Bypass Tray) • RUBBER ROLL ASSEMBLY (PL 2.2 Transport Assembly) • REGI PINCHROLL ASSEMBLY (PL 2.2 Transport Assembly) • REGI PINCH ROLL (PL 2.2 Transport Assembly)

Set the paper size correctly.

check paper size option for you order

C-0 declares that the size of the document you are trying to print is incorrect with the paper size you have in your machine's tray. To remove the error, press the red button on the control panel and check the size of the document within the printing properties. If the papre size of the document and the paper in the tray are correct then try to use another tray or bypass tray. If the problem still persists, call for service.

Most likely the tray setting has changed, Here is what to check.

1. Press the [Machine Status] button on the Control Panel. 'Machine Setup' will be displayed on the Display Screen.
2. Press the [Enter] button.
3. Press the [Left] or [Right] arrow button until the required tray is displayed, and then press the [Enter] button.
4. Press the [Left] or [Right] arrow button until the required paper size is displayed, and then press the [Enter] button.
5. Press the [Stop] button to return to the Standby mode

I am sure you will find one of the tray settings to be incorrect.
If not, click on the printers on your computer, Right click the 4118 and look in the printer properties. One of those settings may be off.
More likely is that the machine settings have changed for whatever reason.

the settings on the print driver and the machine do not match.

1. ress the [Machine Status] button on the Control Panel. 'Machine Setup' will be displayed on the Display Screen.
   
   
   
   
2. Press the [Enter] button.
3. Press the [Left] or [Right] arrow button until the required paper tray is displayed; either [Tray 1 Size], [Tray 2 Size], or [Bypass Size].
4. Press the [Enter] button.
5. Press the [Left] or [Right] arrow button until the paper size loaded in the paper tray is displayed.
6. Press the [Enter] button to save the setting.
7. Press the [Stop] button to return to the Standby mode.
   
   

if that is when your printing you have to check and be sure the paper tray size is set correctly. You press the machine status button and make sure, tray 1, 2 and the bypass are set to the proper size paper.

double check the paper setting and margins set up on your computer.

check the printer properties

The tray itself should have tabs on the side telling the type of paper look at those and see if there is anything broken off.
