Consumable assemblies The user replaces consumable assemblies as part of periodic maintenance. Chapter 4 explains the maintenance procedures. Note The printer tracks the amount of use on some of its user-replaceable parts by keeping a page count. Swapping consumable assemblies between printers might cause a misrepresentation of consumable assembly life values and is not recommended. Table 6-2 Approximate replacement interval for consumable items 1. Approximate lives are based on 2,000 pages per month. 2. The approximate average A4/letter-size page count is based on 5 percent coverage of individual toner colors.
