Hi @Westcliffian,

Welcome to the HP Support Community.

Thank you for posting your query, I will be glad to assist you.

I see that you are facing an issue with scanning from your Printer.

A) Please follow the steps below to perform a power drain.

1) Take out the cartridges

2) Unplug the power cord from the printer & wall.

3) Press and hold the power button down for 15 seconds and release the power button, wait for about 30 seconds.

4) Plug the power cord back into the printer and wall, ensure the printer is plugged into the wall & not into a surge protector.

5) Insert the cartridges back into the printer.

Remove the cartridges > Unplug the power cord > Wait for 30 seconds > Plug the power cord back in > Insert the cartridges

B) Kindly refer to the steps on this link to update the printer firmware and let me know if that resolves the issue.

C) If the issue still persists, uninstall the printer software by following the steps from this link and restart the devices.

D)  Install the printer software by clicking on the link again and let me know if that resolves the issue.

Note: Enable Bluetooth for an HP Smart app setup: Enable Bluetooth on your computer or mobile device so that HP Smart can detect the printer during the setup.

Please mark this post as “Accepted Solution” if the issue is resolved and if you feel this reply was helpful click “Yes”.

I hope this helps.

Take care and have a good day

Hello, Irwin6,

Thank you for your response.

However, I cannot open the printer to remove the cartridges!  The cover will open, but not the next level.  

HELP!

Hi @Westcliffian,

If the carriage does not move to the center, you can continue by just powering off the printer and powering it back on.

 Follow the reset of the steps shared and let me know if that resolves the issue.

Take care and have a great day ahead!

I have the same issue i.e. can still print fine wirelessly from Mac, but can't scan to Mac - when i select printer and "Open scanner" it doesn't appear to locate it and gives error message, "Failed to open a connection to the device (-21345)".

Tried power down, removing printer and reloading drivers and rebooting printer and Mac, issue persists

Have a Deskjet 3835

I have the HP ENVY Photo 7858 All-In-One Printer also.  Printing works but scanner didn't after install of Sequoia.  Did the power drain and it worked.  Thanks

What is the "power drain" method you mention that worked to get your scanner working again?

I too couldn't scan (HP ENVY 5660 All In One) after installing Sequoia. After hours of internet reading, I went into System Settings, Privacy & Security, then Local Network. Turned on all HP items. THE SCAN OPTION WORKS NOW!

I tried all of above suggestions above this one to allow scanning on my HP Officejet Pro 8620 after installing Sequoia on my Intel iMac 27. Thanks Liz. You saved me after hours of trouble shooting. This fix worked.
