We try to Scan to email in 600dpi, but only 300 available in config

[SylvainD]

We need to set our multiple machine by default to 600 dpi for Scan to Email. the menu don't offer us this option on our HP LaserJet Pro MFP M425

Is there a workaround to have those machine that support 600dpi being able to scan at this resolution easily ?

Spec does mention this : 

• Scan Resolution: Up to 1200 x 1200 dpi (monochrome); Up to 600 x 600 dpi (color) Copy Resolution: Up to 600 x 600 dpi Fax Resolution: Up to 300 x 300 dpi

Thanks

If you want higher resolution (higher DPI), you must likely use the scan software on the computer.

This is how most printers work - what you can do on the printer control panel is restricted to what the control panel offers.  Printer and Scan software on the computer is almost always more robust, that is, computer software provides access to more features.

I have not yet found the "proof" in the documentation for this printer, except by way of the example you provide showing the limited number of scan resolution settings.  My conclusion is based on the example and my experience with other printer models and their documentation.

@dragon-fur thanks for your deduction, but I was looking for way to avoid this limitation, maybe with an upgrade micro-code or another menu somewhere.

You are welcome.

I am not aware of any means of getting around hardware limitations.  That means little - I am not a specialist in the technology.  

You might have confused a dedicated scanner device with a printer that prints, scans, copies, and faxes.  Dedicated scanners, at least the higher end models, likely support the higher resolution at the device level.
