Expected page output and replacement cycles
Page yields for 940XL cartridges are measured under ISO/IEC 24711 standard testing for continuous inkjet printing. High-yield C4906AA Black cartridges offer significantly greater output for mono text documents, while C4907AA, C4908AA, and C4909AA colour cartridges deplete at balanced rates during general office printing.

Choosing compatible cartridge options
Choosing compatible 940XL cartridges delivers reliable print quality while substantially lowering office printing costs. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. You can learn more about how non-OEM options perform in our genuine vs compatible cartridges comparison guide.

Consumable Selection Tip
When replacing empty cartridges, always swap out only the specific depleted colour rather than all four at once, as the individual ink architecture of the 940XL system allows each colour cartridge to run until fully exhausted.
Frequently Asked Questions
Do the HP Officejet Pro 8500, 8500a (A910a), and 8500a Plus (A910g) use the same ink cartridges?
Yes, all three models in this series share the same internal platform and accept identical HP 940 and 940XL ink cartridges.
Can I install a single 940XL cartridge alongside standard 940 cartridges?
Yes, standard 940 and high-yield 940XL cartridges share identical fitting dimensions, allowing you to mix standard and XL capacity options in the same printer depending on your usage requirements.
Why does my Officejet Pro 8500 report low yellow or magenta ink when I mostly print black text?
The printer uses tiny amounts of colour ink during routine maintenance routines to keep printhead nozzles clear and prevent permanent clogging, even during mono printing jobs.
Will high-yield 940XL cartridges dry out if my office prints infrequently?
HP 940XL pigment-based inks are formulated to remain stable inside sealed cartridge units, but if printing is infrequent, running a brief test print every couple of weeks keeps the liquid channels flowing smoothly.
