A.3 Life of Consumables and Regular
Replacement Parts
Life of Consumables
Important
•Toner
Reference values are measured based on ISO/IEC19798. Actual replacement cycles depend on printing
conditions, output contents, paper size and type, and environment.
•Drum
The number of printed pages is a reference value based on A4-size one-sided printing of an average of three
continuous sheets per print job. The actual number of printable pages depends on the conditions defined above,
in addition to the number of continuous prints, paper size, paper type, paper feed direction, paper tray and output
tray settings, other mode selections, the initialization operation performed when the printer power is turned on or
off, adjustments to maintain print quality, and other operating environment conditions. Certain conditions may
result in actual values that are half those shown in the table. The values presented here are for reference only.
Regular Replacement Parts
Important
• The printer has certain components that need to be replaced periodically in order to maintain its functionality
and performance. These components are called the regular replacement parts.
The replacement cycles are targets based on continuous, one-sided printing on A4-size plain paper. The actual
number of printable pages can vary greatly from these values due to paper size and type, printing environment
and other printing conditions, such as the frequency of power-ups. This is because the indicated number of pages
are calculated based on estimations of factors that influence actual replacement part life.
Replacement of regular replacement parts should be performed by an engineer. You will be charged for labor as
well as the for the cost of the replacement part.
• Fusing unit
The replacement cycles are targets based on continuous, one-sided printing on A4-size plain paper. The actual
number of printable pages can vary greatly from these values due to paper size and type, printing environment
and other printing conditions, such as the frequency of power-ups. This is because the indicated number of pages
are calculated based on estimations of factors that influence actual replacement part life.
Though the deciding factor for the life of fusing unit, for example, is power on time, this is converted and
indicated as number of print pages.
