Install a Scan driver with and without HP UPD pre-installed
If you want to install a scan driver for an HP MFP product which is supported by the HP UPD using a plug and play
event, you need to make sure that your system is pre-configured correctly before connecting to the printer using USB.
The following approaches are possible:
No HP UPD driver is installed on your Windows PC and the device specific scan driver is pre-installed on the
Windows PC.
HP UPD v5.3.1 or later is installed and the product-specific scan driver is pre-installed.
After connecting to the product using USB, the Scan driver is installed.
In order to be able to install a product-specific Scan driver after a plug and play event which did not install a scan
driver, HP UPD v5.3.1 and later installs an HP PNP Scan Null driver if one or more of the of the following is true:
There is no other scan driver installed on the system that provides a hardware ID match. This might happen if the
driver is on the product CD and the device is connected before the driver is installed from the product CD.
The driver(s) installed on the system that provide a hardware ID match are unsigned.
The driver(s) installed on the system provide a compatible ID match and are older than the HP UPD.
An earlier version (v5.2.x or earlier) is installed on the system.
How to identify if the HP PNP Scan Null driver has been installed:
1. Click Start.
2. Right-click Computer and select Properties.
3. Click Device Manager.
4. Click Imaging devices.
If the device is listed as HP PNP Scan Null, then the HP Null Scan driver is installed.
Replace the HP PNP Scan Null driver with a product-specific Scan driver
1. Click Start.
2. Right-click Computer, and then select Properties.
3. Click Device Manager.
4. Click Imaging devices.
5. Right-click HP PNP Scan Null, and select Update Driver Software….
6. Select Browse my computer for driver software.
7. Select Let me pick from a list of device drivers on my computer.
8. Select Imaging Devices and click Next.
9. If you have a product CD with the correct scan driver, select Have Disk. Otherwise, select Hewlett-Packard from
the Manufacturer list, and the device model in the Model list. Click Next.
