29 SUPPLIES STORAGE OF SUPPLIES Standard SF-2540 supplies replaced by the user include copy paper, toner, toner collecting container, and staple cartridges for the optional staple sorter. Storage of supplies Photoconductive drum The SF-2540 Copier has advanced process control technology which improves copy quality uniformity. This feature stabilizes copy quality throughout the life of the photoconductive drum by automatically compensating for the changes in drum characteristics due to wear, operator use patterns, and environmental conditions. The automatic adjustments are made in response to a sensor that detects the reflectance characteristics of the drum. WARNING This feature requires drums containing the special reflectance area (recommended Sharp genuine photoconductive drum), to prevent low image density copies from poor process control and possible damage to the machine. If you use other drums, the process control system cannot run properly. Proper storage 1 Store the supplies in a location that is: lclean and dry, lat a stable temperature, lnot exposed to direct sunlight. 2 Store copy paper in the wrapper and lying flat. lPaper stored in packages standing up or out of the wrapper may curl or become damp, resulting in paper misfeeds.For best copying results, be sure to use only Sharp products. The package of Sharp toner has the Genuine Supplies label. Downloaded From ManualsPrinter.com Manuals
