Frequently Asked Questions
What is the difference between standard HP 74 and HP 74XL cartridges?
The HP 74 (CB335WA) standard black cartridge contains enough ink for roughly 220 pages, whereas the 74XL (CB336WA) high-yield version holds more ink for up to 750 pages. Both cartridges have identical physical exterior dimensions and fit into the exact same slot in your HP Officejet J5780.
Why does the tri-colour cartridge run out even if I only print in one colour?
The HP 75 (CB337WA) and 75XL (CB338WA) tri-colour cartridges contain cyan, magenta, and yellow ink in three separate internal chambers. When any single colour chamber is depleted, the entire cartridge needs replacing, even if ink remains in the other two chambers.
Can I mix genuine and compatible HP 74/75 cartridges in the same printer?
Yes, you can run a genuine HP 74 (CB335WA) black cartridge alongside a compatible HP 75XL (CB338WA) tri-colour cartridge without experiencing compatibility issues or print errors.
