I If using Windows, access the printer driver (as described on page 25) and check the settings. I Make sure that the print job is being sent to the correct port (for example, LPT1). For Windows 95, Windows 98, or Windows Me, check the settings on the Details tab. For Windows 2000 or Windows NT, check the settings on the Ports tab. I Print a test page from the General tab of the printer driver. If the test page doesn't print, un-install and then reinstall the printer driver. If the test page does print, the problem is not due to the printer or driver; check the application. Indicator lights For the location of the indicator lights on the control panel, see page 2. I If the Data light is off, check the power switch, power cord connection, and power source. I If the Error light is on, check to see that the laser print cartridge is properly inserted in the machine. I If the Error light blinks fast twice, then is off, blinks twice, then is off, etc., the toner in the laser print cartridge is getting low. You can still print approximately 500 pages (with 5% coverage) but may want to order a replacement laser print cartridge; refer to for more information. I If the Paper light and Error light are both on, check for paper jams or misfeeds. I If the Paper light and Error light alternately blink, remove paper from the face-down output tray on top of the printer. I If only the Paper light is on, add paper to the printer. I If the Manual light and Data light are on, the printer is in manual-feed mode. Insert paper in the multi-purpose tray and press the Print button. I If all lights are on, there is a system error. Turn the power off and then back on to clear. If the problem persists, contact Xerox Customer Support. User Guide 17
