Scanning under MacOS Sierra no longer working.

[DavidSMP]

Hi @Exeter6107,

Thanks for stopping by the HP community. A very good day to you. 🙂 I reviewed the post regarding assistance with scanning. I will be delighted to assist you here. 🙂

Superb description and stupendous diagnosis of the issue before posting. Kudos to you for that. 🙂

For better clarity and to assist you better I would require information regarding this:

• Did you try to copy directly from the printer to check if it copies fine?
• Please let me know the exact model# of the printer to assist you better.

For now please try these steps:

• Please make 1 copy in color directly from the printer to eliminate hardware issues with it.
• If it copies fine then please try these steps:

Please reset the Mac printing system from this link: http://hp.care/2gOrf2g and then add the printer as an HP printer.

.) Click the Apple menu icon, and then click System Preferences.

2.) Click Printers and Scanners, Print and Scan, or Print and Fax.

3.) In the Printers list, click your HP printer, and then click the Minus button to delete it.

4.) Click the Add button.

 5.) Find, and then select the name of your printer from the Printer list, and then click Add to add your printer. Do not select an HP Fax driver.

6.) Click the Use or Print Using box, and then select the name of your printer.

7.) Avoid the AirPrint driver. Once the correct HP driver is chosen, select Add to add the printer to the list.

8.) Try to print.

This should fix the issue.

Then use this link: http://hp.care/2uTCeOI to download HP Easy scan and install it. It gives you steps to download, install and use HP easy scan along with FAQs and other methods to scan. It gives you other options to scan as well.

Please perform all these steps patiently as it is critical to resolving the issue. The trick is to remain patient, Going by your technical expertise and competence I am sure you will be able to perform these steps without breaking a sweat. 🙂

Hope this helps. Let me know how this goes. I genuinely hope the issue gets resolved without hassles and the unit works great.
