ADJUSTING WINDOWS PRINTER DRIVERS
Once your new upgrade has been installed, you may need to 
update the Windows printer driver so that the additional features 
are available to your Windows applications.
Remember that if your printer is shared between users on 
different computers, the driver must be adjusted on each user’s 
machine.
The illustrations shown here are for Windows XP. Other Windows 
versions may appear slightly different, but the principles are the 
same.
PCL DRIVER
If you have installed a memory upgrade it is not necessary to 
change the PCL printer driver, and you can ignore this section.
If you have installed a duplex unit or hard disk, proceed as 
follows:
1.Open the Printers window 
(called “Printers and Faxes” in 
Windows XP) via the Start Menu 
or from the Windows Control 
Panel.
2.Right-click the printer icon for 
this printer, and choose 
Properties from the pop-up 
menu.
3.On the Device Options tab, 
check the box for the upgrade 
you have just installed.
4.Click OK to close the properties window, and then close 
the Printers window.

CLEARING PAPER JAMS
Provided that you follow the recommendations in this guide on 
the use of print media, and you keep the media in good condition 
prior to use, your printer should give years of reliable service. 
However, paper jams occasionally do occur, and this section 
explains how to clear them quickly and simply.
Jams can occur due to paper misfeeding from a paper tray or at 
any point on the paper path through the printer. When a jam 
occurs, the printer immediately stops, and the Alert LED on the 
Status Panel (together with the Status Monitor) informs you of 
the event. If printing multiple pages (or copies), do not assume 
that, having cleared an obvious sheet, others will not also be 
stopped somewhere along the path. These must also be removed 
in order to clear the jam fully and restore normal operation.
