Troubleshooting Tips
"Cartridge Problem" error: Remove both cartridges, wipe the copper contacts with a lint-free cloth, and reinsert firmly until they click.
Streaky or faded prints: Run Tools > Clean Printhead from the printer's touchscreen. Repeat up to three times if needed.
Alignment issues: After installing a new cartridge, print an alignment page from Tools > Align Printer to restore sharp text and color registration.

Frequently Asked Questions
Will compatible HP 64XL cartridges void my printer warranty?
No. The federal Magnuson-Moss Warranty Act prohibits manufacturers from voiding your warranty for using third-party ink, as long as the ink itself didn't cause damage.
How are page yields calculated?
Yields follow the ISO/IEC 24711 standard at 5% page coverage. Photo-heavy printing will use ink faster than mixed text and graphics.
What other printers use HP 64 ink?
The HP Envy Photo 6200, 6220, 6230, 6252, 6255, 7100, 7120, 7130, 7155, 7158, 7164, 7800, 7820, 7830, and 7858 all share the HP 64 / 64XL family.
Should I buy HP 64 or HP 64XL?
HP 64XL delivers roughly three times the pages of standard HP 64 for only a modest price increase, making the XL the better value for nearly every user.
Why does my Envy 7855 keep warning me about low ink?
HP cartridges report a "low" status well before they're actually empty. You can usually keep printing dozens of pages after the first warning — wait until print quality drops before swapping.
