Scanner Function Not Detected -LaserJet Pro MFP M28a not detected on Mac computers but OK on Windows

[tired_user]

There is no software that should cause this kind of a problem on my laptop.

Did you have a comment on the potential USB 2/3 issue?

@tired_user

If you plug in a USB 2 device into the USB 3 port all devices connected or "daisy-chained" to that hub will operate up to the maximum transfer rate of USB 2 speed (480 Mbps).

USB 3 devices can use up to 900mA of power (compared to 500mA used by USB 2 devices). You'll need to use a USB 3 cable to use the 900mA of power available. USB 2 cables don't support 900mA.

Your device should be backward-compatible with USB 2 ports. However, you won't get USB 3 speed and power may be limited to 500mA.

The printers have a USB 2.0 port only.

If the issue persists, kindly contact HP Support team for further assistance.

1) Click on this link - www.hp.com/contacthp/

2) Select your product type below.

3) Enter the serial of your device.

4) Select the country from the drop-down.

5) Select the appropriate option based on your preference.

6) Fill the web-form and proceed further.

Keep me posted for any other assistance.

Hallo,

the firmware on the HP Server is not the correct one. Could you please send me the working firmware update for using the scanner under MAC via USB?

Thank you in advance.

Please try below steps in exact order and let me know if that may help:

1. Unplug the USB from the printer and restart the printer.
2. Restart your Mac
3. Open System Preferences > Printers & Scanners
4. Right-click the printers list (or CTRL + Left Click) and select Reset Printing System.
5. Plug the USB and check the added print queue.

If it still doesn't list the scan option, click the plus sign under System Preferences make sure you select the USB Multifunction instance (type) of your printer.
