Memory Problems
Print quality decreased

printer can continue printing.Check to see if the printout is acceptable.
If not, add more memory for a 
permanent solution or lower print 
quality temporarily in the printer driver.

memory for current task.Add more memory for a permanent 
solution or lower print quality

Correcting USB Problems
If you are having difficulty using the printer with a USB 
connection, see if your problem is listed below, and take any 
recommended actions.
USB connections
USB cables or connections can sometimes be the source of USB 
problems. Try one or both of these solution.
❏For best results, you should connect the printer directly to the 
computer’s USB port. If you must use multiple USB hubs, we 
recommend that you connect the printer to the first-tier hub.
Windows operating system
Your computer must be a model pre-installed with Windows XP, 
Me, 98, 2000, or Server 2003, a model that was pre-installed with 
Windows 98 and upgraded to Windows Me, or a model that was 
pre-installed with Windows Me, 98, 2000, or Server 2003, and 
upgraded to Windows XP. You may not be able to install or run 
the USB printer driver on a computer that does not meet these 
specifications or that is not equipped with a built-in USB port.
For details about your computer, contact your dealer.
Printer software installation
Incorrect or incomplete software installation can lead to USB 
problems. Take note of the following and perform the 
recommended checks to ensure proper installation.
 
						

							210Troubleshooting
Checking printer software installation for Windows 2000, XP, 
or Server 2003
When using Windows XP, 2000, or Server 2003, you must follow 
the steps in the Setup Guide packed with the printer to install the 
printer software. Otherwise, Microsoft’s Universal driver may be 
installed instead. To check if the Universal driver has been 
installed follow the steps below.
1. Open the Printers folder, then right-click the icon of your 
printer.
2. Click Printing Preferences on the shortcut menu that 
appears, then right-click anywhere in the driver.
If About is displayed in the shortcut menu that appears, click 
it. If a message box with the words “Unidrv Printer Driver” 
appears, you must reinstall the printer software as described 
in the Setup Guide. If About is not displayed, the printer 
software has been installed correctly.
Note:
For Windows 2000, if the Digital Signature Not Found dialog box 
appears during the installation process, click Yes. If you click No, you 
will have to install the printer software again.
For Windows XP or Server 2003, if the Software Installation dialog box 
appears during the installation process, click Continue Anyway. If 
you click STOP Installation, you will have to install the printer software 
again.
