Difficulty Print Quality Difficulties (Cont.) Nothing is printed on the page. White Page Printed pages are marked at regular intervals. Example of Regular Marking Printed pages are blurred at the center or at either edge. Blurred Page Ghost images appear on printed page. Ghost Images Suggestions Make sure that the toner cartridge is not empty. Wipe electric terminals referring to Routine Maintenance, Cleaning the Printer and Cleaning the Drum Unit, on pages 22-18 and 22-19. Make sure that a torn piece of paper does not remain on the scanner window. Markings may disappear by themselves. Try copying multiple pages to clear this problem. Markings may occur if the machine has not been used for a long time. A possible cause is that the surface of the drum is scratched. You must then replace the drum unit with a new one. If the markings do not disappear, it may be that the drum was marked or damaged by excessive exposure to light. In this case, replace the drum unit with a new one. Certain environmental conditions such as humidity, high temperatures, etc. may cause this condition to occur. Make sure the machine is placed on a flat, horizontal surface. Remove the drum unit with the toner cartridge installed. Try rocking them from side to side. You may clear a blurred page by wiping the scanner windows with a clean soft cloth. (See Routine Maintenance, Cleaning the Printer and Cleaning the Drum Unit, on pages 22-18 and 22-19.) If a blurred page occurs after cleaning and the display shows CHANGE DRUM SOON, replace the drum unit with a new one. Adjust the print conditions by setting the Print Density function. Make sure that you use paper that meets the specifications. Rough surfaces or thick media can cause a ghost image. Make sure that you select the appropriate media type in the printer driver. The drum unit is a consumable item and it is necessary to replace it periodically. T R O U B L E S H O O T I N G A N D R O U T I N E M A I N T E N A N C E 22 - 13
