Regionalization reset of HP7740

[Alex10021]

I have an HP Officejet Pro 7740. The printer originally came with HP 953 and 957 cartridges.

As soon as I put the 952 cartridges, the printer LCD displays: "Incompatible Cartridges: The indicated cartridges are not intended for use in this printer."

I am writing this message to HP Support, to request resetting the regionalisation of my printer, to accept the 952 cartridges. Could you please help me by sending full instructions on how to reset the regionalisation of my printer and also if I need to input any special codes, if I need to input them in any sort of regionalisation settings menu so that I can use these cartridges?

Thanks.

Hi @Alex10021,

Welcome to the HP Support Community

I'd like to help!

I understand you moved and the printer is not accepting the new region cartridges.

We need to perform a regional reset on the printer to resolve this issue. 

The reset instructions are specific for your printer and performing those steps on a different printer may brick the device. 

I've sent you a private message with reset instructions, follow the reset instruction to perform a full reset and re-initialize the printer. 

In order to access your private messages, click the private message icon on the upper right corner of your HP Support Community profile, next to your profile Name or simply click on this link.

Hope this helps! Keep me posted.
