4511-xxx Print quality problems (continued) Problem Action 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). While using manual duplex, the printer gets a paper jam. • Ensure correct printer driver is being used. • 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 assembly is installed properly. • Make sure the printer top cover is closed. • Ensure the correct PostScript driver is being used. • The printer doesn't have enough memory to print the job. Install more memory. A paper jam interrupts the duplex process. As a result, the information on the page that jammed is lost. • Press and release to cancel the print job (E238, E240, E240n) or press Menu and select Cancel (E340, E342n). • Press and hold (approximately 3 seconds) to reset the printer. • Resend the print job. 2-110 Service Manual
