For refilled HP 934/935, HP 950/951 or HP 970/971 ink cartridge series printer models which display printer/cartridge error messages such as “cartridge missing or damaged”, “cartridge problem”, “cartridge depleted”, etc., and printing is not permitted, there is a new HP printer firmware update available for your printer model which will enable refilled ink cartridges to function normally (released Sept. 19 2017).  Click on the link below; this will explain the issue & offer a printer firmware download to fix the issue and allow you to continue using refilled ink cartridges: click here

NOTE: In compliance with General Data Protection Regulations (European customers), we will remove any personal information from our database upon your request. 



* For a compatible, remanufactured or re-branded ink cartridge which has been purchased on-line or at select retailers (i.e  sold under a different label than a trademarked HP, Canon, Epson or Brother cartridge) we would need to know this as well to properly assist you. For ease in identification, remanufactured (original cartridges which have been refilled but exhibit a different brand name) and clone/compatible cartridges (some of which are illegally imported into the US/Canada/Europe) will NOT have the HP, Canon, Epson or Brother trademark logo engraved or affixed to the cartridge’s top or side label.


ᵻ What is GDPR and how does Inkjet411 protect your personal information?


What is GDPR?

The General Data Protection Regulation (GDPR) 2016/679 is a regulation in EU law on data protection and privacy for all individuals within the European Union. GDRP standardizes data protection law across all 28 EU countries as well as imposes strict new rules on controlling and processing personally identifiable information (PII).

GDPR applies to all organizations holding and processing EU resident’s personal data, regardless of geographic location. If an organization offers goods or services to, or monitors the behavior of EU residents, it must meet GDPR compliance requirements.


What is considered personally identifiable information (PII)?

PII is information that can be used on its own or with other information to identify, contact, or locate a single person, or to identify an individual in context. The types of data considered personal go beyond just name, address, and photos. GDPR extends the definition of personal data to include other identifiable attributes, as applicable.


What has Inkjet411 done to protect your personal information?

  • We are collecting only the necessary data (typically name, city & e-mail) needed to perform the technical support services you requested with your Inkjet411 inquiry, and we are limiting the storage periods for that data.
  • We are providing the following personal data rights to our customers in accordance with the GDPR, including the right to be informed, the right to rectification, the right to erasure, the right to object and the right to withdraw consent.
  • We will not share your personal data with anyone outside of Inkjet411 support team or the respective retailer where you had your ink cartridge refilled.


If you fill out the inquiry form above then you have provided us initial consent to respond to your inquiry and maintain a record of the support provided (typically via an e-mail response). At any time, you may contact us with a request to delete your personal information from within our database.

We are committed to protecting and respecting your privacy. If you have any questions regarding the GDPR and how Inkjet411 treats your personal information, please send us an email at


Kind regards,

The Inkjet411 Team
