2-Color Draft You can select 2-Color Draft to reduce the amount of toner you use when printing color drafts. Selecting 2-Color Draft decreases the amount of toner by using only two colors of toner instead of four colors. Avoiding print quality problems To prevent print quality problems, do not touch the print cartridge photoconductors, the transfer belt, 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. Refer to "Media guidelines" on page 98 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 "When to replace supplies" on page 116 for more information. 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 12A5150 (letter size) P/N 12A5151 (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, you may find the print quality unacceptable. Handle transparencies carefully. The reason for this is that fingerprints may affect the adhesion of toner on your transparency. Always set the Paper Type to Transparency before printing 86 Chapter 4: Using color
