1 HP Maintenance/Long Life Consumables (LLC) life specifications are estimations based on the LLC life test conditions listed below. Actual
individual life/yield during normal use varies depending on usage, environment, paper and other factors. Estimated life is not an implied
guarantee or warrantable.
* The LLC life test conditions:
● Print coverage: 5% evenly distributed across the page
● Environment: 17° to 25°C (62.6° to 77°F); 30%-70% relative humidity (RH)
● Media size: Letter/A4
● Media weight: 75 g/m 2 (20 lb) plain media
● Job size: 4 pages or more on average
● Long-edge feed (Letter/A4)
Factors that can reduce life from the conditions above:
● Media narrower than Letter/A4 widths (thermal slowdowns equal more rotations)
● Paper heavier than 75 g/m 2 (20 lb) (heavier media creates higher stress on printer components)
● Print jobs smaller than 4 pages (smaller jobs mean more thermal cycling and more rotations)
