Imaging drum information
This printer indicates when an imaging drum level is low and very low. The actual imaging drum life remaining
can vary. Consider having a replacement imaging drum available to install when print quality is no longer
acceptable.
To purchase imaging drums or check imaging drum compatibility for the printer, go to HP SureSupply at
www.hp.com/go/suresupply . Scroll to the bottom of the page and verify that the country/region is correct.
The printer uses four imaging drums installed next to each toner cartridge. One universal imaging drum part fits
in all four positions. The imaging drums are inside the front door.
