When you want to clear your HP printer memory before disposal, there are a few things that you can do. First, you can try to remove any personal data that may be stored on the device. This includes any files or documents that you have stored on the device. To do this, you will need to access the printer's memory and delete these files.
Next, you can factory reset the printer. This will erase all of the data and settings from the device and restore it to its default state. To do this, you will need to access the printer's menu and navigate to the factory reset option. Once you have selected this option, follow the prompts to complete the reset process.
Finally, if you still have concerns about data being stored on your HP printer after completing these steps, you can contact HP customer support for further assistance.
