Changing region on my HP MW28w printer?

[Rich2541]

Hello, I moved from Hong Kong to the United Kingdom in 2023 and our current print cartridge is on its last legs. I applied for a new one via the HP Smart app and it arrived a few days ago. However, it was the HP 44A Black Original LaserJet Toner Cartridge, whereas my old one was a HP 48A cartridge. From some online searching, I've discovered that my printer won't accept the HP 44A cartridges because the printer is regionally locked. 

I wanted to request some support/guidance to change the regional configuration of my printer so that it accepts the print cartridge I bought for it (as you probably know, the HP 48A cartridges are not available in the UK). I'd appreciate the support (and see that some other people have had similar issues, and have had IT support people reach out and say they need direct guidance). 

Many thanks in advance.

Hi @Rich2541,

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 to 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 instructions to perform a full reset and re-initialize the printer. 

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.

You can try the factory set default first, form user guide page 60 ( pdf page 68 ).

Restore the factory-set defaults

Restoring the factory-set defaults returns all of the printer and network settings to the factory defaults. It will
not reset the page count. To restore the printer to the factory-default settings, follow these steps.
CAUTION: Restoring the factory-set defaults returns all of the settings to the factory defaults, and it also
deletes any pages that are stored in the memory.

1. Open the HP Embedded Web Server (EWS):
Direct-connected printers
a. Open the HP Printer Assistant.
● Windows 10: From the Start menu, click All Apps, click HP, and then select the printer name.
● Windows 8.1: Click the down arrow in lower left corner of the Start screen, and then select the
printer name.
● Windows 8: Right-click an empty area on the Start screen, click All Apps on the app bar, and then
select the printer name.
● Windows 7: From the computer desktop, click Start, select All Programs, click HP, click the folder
for the printer, and then select the printer name.
b. In the HP Printer Assistant, select Print, and then select HP Device Toolbox.
Network-connected printers
a. Print a configuration page to determine the IP address or host name.
i. Press and hold the Start Copy button until the Ready light begins blinking.
ii. Release the Start Copy button.
b. Open a web browser, and in the address line, type the IP address or host name exactly as it displays
on the printer configuration page. Press the Enter key on the computer keyboard. The EWS opens.
NOTE: If the web browser displays a message indicating that accessing the website might not be
