computer does not recognize scanner on HP Photosmart 7520

[Jay_M40]

I have an HP Envy x 360, networked with an old HP Photosmart 7520 printer/ scanner. The printer works fine, but when I tried to scan a document, the computer said there was no scanner, and the scanner said no computer. I just installed a driver for the 7520, but the problem persists. The Windows setting says the driver is unavailable. Ironically, I was able to scan a test at one stage of this, but I cannot recreate the circumstances.

Not sure - the printer software for the older 7520 is not "new", though the software is presumably still compatible with the latest version of Windows 10.

You could try:

• Completely uninstall / install the printer software in an attempt to get the driver to be recognised (fully installed printer software)
• Set a TCP/IP port

Installation - Printer Software

NOTES

• If using USB, disconnect the USB cable between the printer and the computer before starting the installation.
• Connect the cable when instructed to do so (toward the end of the installation procedure).

• Some (newer) printer models provide the "Easy Start" install method. When applicable, Easy Start will be found in the Software and Drivers website support page > Category Software \
• Within Easy Start, you will be given the opportunity to install the software that is available.  Full Feature Software might be described as the "Full Driver" software.

** Optional - For Windows 10 Users – Compatibility Mode **

If you have been having trouble getting the printer software to fully install (Printer Assistant is functional and Scanning works), consider using Compatibility.  Note that this method only fixes “one type” of difficulty; installing this way may – or may not – make the necessary difference.

Right-Click on the downloaded installation file > Properties > Compatibility

Firmware

Consider installing the printer Firmware

READ (when provided) all information and instructions before installing the firmware

If / After the firmware is installed, Restart the computer and log in

Reminder:  Firmware is normally updated after the printer software is installed / functional.

Port Issues - Create a TCP/IP port

The assigned port may fail to connect the printer or certain printer activities (Scan).  Create / Switch to a TCP/IP Port to facilitate communication and prevent ‘offline’ issues

How-to “Create TCP Port” Contributed by  greenturtle:

Create TCP IP port

1. Print a Configuration Page to get the printer's IPv4 address (you can also tap on the wireless icon on the Front panel of your Printer to get the IP address)
2. On your PC, go to Control Panel, from Devices and Printers, Right-Click the printer and Left-Click Printer Properties, select the Ports tab.
3. Click Add Port, select Standard TCP/IP Port, then select New Port and follow the wizard.
4. Type in the proper IP address for the printer.

This video resource will show you how to do it:
Create & Use TCP IP port

Note that you can ALWAYS revert back to the original port that the HP software installed by selecting the HP port under the Ports tab (in Printer Properties)

HP Scan Extended

IF you can get the printer software to completely install, the following "subset" software can be added to provide some nice features not found in the original HP Scan software.

Reminder:  HP Scan Extended does not "fix" the issue with uninstalled or "partially" installed printer software.

Link / Download:  HP Scan Extended 

Download, save, and install to use.  Exceptional free HP scan program:  HP Scan Extended features include (and are not limited to): Single, Multiple scans, Image and PDF scans, Email as PDF / JPEG, Source selection, Page Size choices include Auto-Detect (extracts image / document boundary).  May include OCR (Save as Editable Text).

NOTES

• HPSE is an older subset of the printer software; features are very similar to scan software included in 2015 or newer Full Feature Software packages.
• If you have the newer version of the scan software inside your Full Feature Software, use the Printer Assistant shortcut icon on Desktop (named for printer) > Scan a document or image (wording varies).
• Although the HPSE program works as a separate program, HPSE is dependent on the infrastructure provided by the printer software. The Full Feature Software for your printer should be installed before installing HPSE.
• OPTIONAL: Add HP Scan Extended shortcut to Taskbar / Send to Desktop / Pin to Start
  • Open File Explorer > Navigate to C:\Program Files (x86)\HP\HP Scan Extended\bin
  • Right-Click exe > Select Pin to Taskbar / Send to Desktop / Pin to Start

Thank you for the reply. After I wrote the original message, I realized that I had not rebooted (doh!). I did that, and I can now access the scanner, using the scan prompt in the Windows 10 menu. However, if I ask for a scan, a message says there is a "problem." If I "preview," though, I can then scan. The only big problem is that I can't seem to scan more than one page at a time; there seems to be no option for combining a multi-page document into one pdf file, which is what I need.

Any advice? 

PS: I will not be checking to board again until tomorrow.  Thanks.

You are welcome.

I am not sure what you mean here:

I can now access the scanner, using the scan prompt in the Windows 10 menu

How are you "asking for a scan", that is, what program / software are you using to submit the job to the printer?

Where are you seeing there is a "problem" message?

If you use the printer software on the computer, you can "add pages" to your scan job.  The printer itself may not offer this option since the printer scan is "basic" without any added features.

OK, download and run the doctor and see if it can fix issues for you:
