How many pages does it print?
Prints up to 1,000 pages measured according to ISO/IEC 24711 with 5% coverage. This is the same methodology HP uses for its original 934XL 935XL cartridge, so the comparison is honest. Real yield depends on the document type: dense text yields less, while emails and low-coverage documents yield somewhat more.

Will I lose my printer's warranty?
No. Art. 120 of RDL 1/2007 and Directive (EU) 2019/771 prohibit the manufacturer from voiding your warranty for using compatible consumables. According to Directive (EU) 2024/1799 on the right to repair (in force July 31, 2026), using compatible cartridges does not affect the manufacturer's warranty.
If your HP printer shows "non-original cartridge" after an HP Dynamic Security update, do not update the firmware while using compatibles. If it persists, we are here to help: your cartridge has a 3-year legal warranty.
Frequently Asked Questions
Is it compatible with my printer?
Yes. This compatible HP 934XL 935XL consumable works in 11 HP models. If you don't see yours in the list, write to us before buying and we will confirm it in less than 24 hours.
Does using a compatible cartridge void my printer's warranty?
No. Using a compatible cartridge does not void your printer's warranty. It is backed by Art. 120 of RDL 1/2007 and Directive (EU) 2019/771: the manufacturer must prove in writing that the damage was caused by the consumable. Further supported by Directive (EU) 2024/1799 on the right to repair.
How many pages does it print?
Up to 1,000 pages measured according to ISO/IEC 24711 with 5% coverage. Actual yield depends on the type of document: dense text yields less, light graphics may yield more.
How long does shipping take?
24-48h shipping. Orders before 5:00 PM are shipped the same day. Free shipping for orders over €50; below that, €3.99.
What if it arrives defective or doesn't work?
Free exchange within 14 calendar days (Art. 102 RDL 1/2007) and 3-year legal warranty (Art. 120). If it doesn't work, we'll send you a new one with a tracking number without you having to return the first one.
Why doesn't my HP printer recognize the compatible cartridge?
Turn off the printer for 60 seconds and turn it back on; the chip synchronizes with the firmware during that time. If it continues, remove the cartridge and clean the gold contacts with a dry cotton swab. Do not update HP firmware while using compatibles: some versions of Dynamic Security block them...
Does the ink have an expiration date?
The date on the box is the "warranty end date," not real expiration. Well-stored in a cool, dry place, this cartridge lasts 2-3 years unopened.
What do I do if the printer says the cartridge is empty and it's new?
Remove the cartridge, clean the chip with a cotton swab and a little alcohol, and put it back until you hear a click. If it continues, turn off the printer for 5 minutes. If the problem persists, write to us: you have a 3-year warranty.
