SUPPLIES Genuine supplies statement Standard supplies for this copier that are to be replaced by the user are copy paper, TD cartridge, and drum cartridge. For best copying results, be sure to use only SHARP Genuine Supplies which are designed, engineered and tested to maximize the life and performance of SHARP copiers. Look for the Genuine Supplies label on the TD cartridge and drum cartridge. Supplies GENUINE SUPPLIES Photoconductive drum The AL-1600/AL-1610 Copiers have 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 a special area of the drum. 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: q clean and dry, q at a stable temperature, q not exposed to direct sunlight. 2. Store copy paper in the wrapper and lying flat. q Paper stored out of the wrapper or in packages standing on end may curl or get damp, resulting in paper misfeeds. 47 GENERAL INFORMATION
