9 Avoiding print quality problems To prevent print quality problems, do not touch the print cartridge toner roller, photo developer transfer film, or the fuser rollers. Scratches or fingerprints on any of these surfaces can adversely affect print quality. Media and supplies Always use media that meets the recommended guidelines. See Media guidelines for more information. Feeding media that is too heavy, too light, damp, damaged, or otherwise unacceptable for this printer may result in print quality problems. Some print quality problems may indicate it is time to replace certain printer supplies. Check the operator panel display, the Supplies Menu, or MarkVision for an indication of any supply items that may need to be replaced. Depending on the type of jobs you print and the media you use, some parts or supplies may wear or become expended faster than anticipated. See Maintenance for more information about supplies and when to replace them. Transparencies To ensure high quality output on transparencies, we recommend using the following Lexmark transparencies. They have been designed specifically for your printer: P/N 12A5590 (letter size) P/N 12A5591 (A4 size) These transparencies have characteristics that minimize curl and optimize toner transfer in a wide range of printing environments. If you use other transparencies, the print quality may be unacceptable. Handle transparencies carefully because fingerprints may affect the adhesion of toner. Always set the Paper Type to Transparency (see Changing the Paper Type setting) before printing transparencies. This adjusts the fuser temperature and slows the print speed to ensure the best possible transfer of toner. See Loading transparencies for more information. 34
