● Handle transparencies by the edges. Skin oil on the surface of transparencies can cause spots and smudges. ● Small, random dark areas on the trailing edge of solid fill pages may be caused by transparencies sticking together in the output bin. Try printing the job in smaller batches. ● The selected colors are undesirable when printed. Select different colors in the software application or printer driver. ● If you are using a reflective overhead projector, use a standard overhead projector instead. Print quality problems associated with the environment Print quality problems can occur if the printer is operating in an environment outside of the printer specifications (see Printer specifications). Print quality problems associated with jams Make sure that all paper is cleared from the paper path. See Paper jam recovery. ● If the printer recently jammed, print two to three pages to clean the printer. ● If the paper does not pass through the fuser, which causes image defects to appear on subsequent documents, print two to three pages to clean the printer. However, if the problem persists see the next section. Print quality problems associated with maintenance Some print quality problems might occur when the printer needs cleaning. See Periodic cleaning for more information. Print quality troubleshooting pages The print quality troubleshooting pages provide information on aspects of the printer that affect print quality. 1.
