4500 Problem Unexpected characters print or characters are missing. Jobs are not printing and the Error light is on solid. While in PostScript® 3 emulation, the printer is flushing data (Ready/Data and Error lights are blinking). Manual duplex isn't on the printer. While using manual duplex, the printer gets a paper jam. Action • Ensure correct printer driver is being used. • Press and hold Continue until all lights come on to reset printer to user default settings. • Select hex trace mode to determine what the problem is. • Restore factory defaults. • Make sure the parallel cable or USB cable is firmly plugged in at the back of the printer. • Make sure the print cartridge is installed properly. • Make sure the printer top cover is closed. • Ensure the correct PostScript driver is being used. • The Lexmark E220, E320, and E321 do not support PostScript emulation. • The printer doesn't have enough memory to print the job. Install more memory. The printer driver may not support manual duplex. Go to the Lexmark Web site at www.lexmark.com to download the latest printer driver. A paper jam interrupts the duplex process. As a result, the information on the page that jammed is lost. • Press and release Cancel to cancel the print job. • Press and hold Cancel (approximately 3 seconds) to reset the printer. • Resend the print job. 2-98 Service Manual
