Expected page output and replacement cycles
Page yield calculations for HP inkjet cartridges follow international ISO/IEC 24711 testing standards using continuous print runs. Standard yield testing assumes five percent page coverage on standard A4 paper. Printing full-bleed A3 graphics or dense colour spreadsheets consumes ink significantly faster than regular text documents.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| 88XL | High Yield | Magenta | 1,980 | $0.014 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.
Best way to stock these cartridges
For office environments producing high-volume marketing collateral, buying high-yield 88XL (C9392A) cartridges ensures your printing workflow remains efficient. Replacing depleted colour tanks individually keeps your operating expenses focused only on the ink you actually consume. Keep spare cartridges in stock to prevent workflow pauses during long print jobs. Order genuine HP ink cartridges directly from Ink Depot. All purchases are backed by our transparent Returns policy. We ship promptly from local warehouses located in Perth, Brisbane, Sydney, Melbourne and Adelaide. Free delivery applies on all orders over $99.
Pro Tip
When producing wide-format A3 prints or heavy colour graphics, monitor individual colour levels in your print queue early. High-coverage prints deplete individual colours unevenly, so keeping a spare 88XL (C9392A) on hand prevents interrupted jobs mid-page.
Frequently Asked Questions
Do the HP Officejet Pro K8600 and K8600dn use the exact same ink cartridges?
Yes. Both the base K8600 and the network/duplex K8600dn models share the exact same internal print engine and accept identical HP 88 and 88XL series ink cartridges.
How does standard page yield compare when printing A3 wide-format documents versus standard A4 pages?
Official ISO/IEC yields are based on standard A4 test pages at 5% coverage. Printing on larger A3 sheets covers twice the printable surface area, which effectively halves the number of completed pages you can expect from a single cartridge.
Can I install individual 88XL cartridges without replacing the entire colour set?
Yes. The printer features an individual modular ink system, allowing you to replace the 88XL (C9392A) cartridge independently whenever that specific colour runs out without discarding active ink in other slots.
What is the shelf life of an unopened 88XL (C9392A) ink cartridge?
Unopened genuine HP ink cartridges stored in a cool, dry place away from direct sunlight typically maintain full print quality for up to 18 to 24 months from the manufacture date.
