Life expectancies of components Inspect components when servicing the printer. Replace components as needed, based on failure or wear, rather than on usage. The following table lists approximate schedules for replacing components. Table 11. Life expectancies of components Description Part number Estimated Remarks life (pages) HP LaserJet 1150 print cartridge (user replaceable) Q2624A 2,500 When print becomes faint, redistribute toner in the cartridge by gently shaking the cartridge from side to side. HP LaserJet 1300 print cartridge (user replaceable) Q2613A Q2613X 2,500 4,000 When print becomes faint, redistribute toner in the cartridge by gently shaking the cartridge from side to side. Printer transfer roller RM1-0545-000CN 50,000 Can affect print quality and/or paper movement. Printer pickup roller RL1-0303-000CN 50,000 Look for glazing and/or cracks. Printer separation pad RF0-1014-000CN 50,000 Can affect paper movement. Fuser assembly (100-127 V) RM1-0535-000CN 50,000 Can affect print quality and paper movement. Fuser assembly (220-240 V) RM1-0536-000CN 50,000 Can affect print quality and paper movement. * The estimated print cartridge life is based on letter- or A4-sized paper with an average of five percent toner coverage and a medium density setting. Print cartridge life can be extended further by conserving toner using the EconoMode setting. However, HP does not recommend full-time use of EconoMode. If EconoMode is used full-time when the average toner coverage is significantly less than five percent, it is possible that the toner supply will outlast the mechanical parts in the print cartridge. User-replaceable parts Replace the printer pickup roller and the printer separation pad when the parts are near the end of their life expectancies or if media frequently misfeeds. 38 Chapter 3 - Maintenance ENWW
