Expected page output and replacement cycles
Page yield testing for inkjet cartridges follows standard ISO/IEC guidelines for monochrome document coverage. Yield values reflect standard text pages, though heavy font usage or high-density graphics will deplete black ink faster.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| 45 | Standard | Black | 883 | $0.15 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.

Frequently Asked Questions
How does the high-capacity ink formula in 45 (51645AA) black cartridges handle long idle periods?
HP 45 (51645AA) cartridges use high-density pigment ink designed to resist drying out inside the printhead nozzle plate, provided the protective tape remains on until installation and the printer is powered down properly so the printhead parks in its sealed cap.
Why is the page yield slightly different between genuine and compatible 45 (51645AA) cartridges?
Genuine HP 45 (51645AA) cartridges are rated at approximately 883 pages under standard coverage testing, while compatible versions yield around 833 pages due to slight variations in liquid fill volume, though both deliver comparable dark line sharpness for text documents.
Will using compatible 45 (51645AA) cartridges cause micro-clogging on thermal inkjet printhead nozzles?
Premium compatible 45 (51645AA) ink formulations match the viscosity and thermal boiling points required by HP thermal inkjet firing chambers, preventing residue buildup while ensuring consistent ink flow across long print runs.
