HP Photosmart 7520 not connected to computer when trying to scan

Hi!!
I have an IMac. I can print from my computer, and my computer recognizes my printer (HP Photosmart 7520), however, my printer will not connect to my iMac...Help! ;-)
When I am trying to scan, the exact warning is: "No Connection: No computer is connected. See printer Help and documentation to troubleshoot the connection."
When I go to printer Help and doc, it says to install the HP software on my computer.
I already went through most of the troubleshooting steps I could find (on my computer and online) - they only dealt with my computer not recognizing my printer...not vice versa...
The little bluetooth light is lit and going strong...
Thanks in advance!!!

Hi @ktsue,
Welcome to the HP Forums!
I understand that you cannot scan with your HP Photosmart 7520 on your Mac. I am happy to help you with this scanning issue!
For further assistance, I will need some additional information:
The version of Mac Operating System that you are using. To find the exact version, visit this link. Whatsmyos.
If the printer is connected, Wireless, or USB.
If the printer is able to make copies. Copy Text or Mixed Documents.
If the power cable is plugged into a surge protector, or directly to the wall outlet. Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector. This applies to Inkjet printers as well.
In the meantime, please see this scanning guide, A 'No Computer Detected' or 'Connection Error' Message Displays for HP Photosmart 7520 e-All-in-One .... (Even though the guide title may not match your issue, I believe the solutions will help).
Thank you for posting!

Hp officejet 6500a/ using 8.1/ when trying to scan it keeps telling me no computer detected???

ANY HELP FORTHCOMMING WOULD BE APPRECIATED, ITS DRIVING ME NUTS!!!! TX.

Hi,
Have you installed new software and drivers on Windows 8.1 machine yet ? If yes, please initiate scan from computer first. Scan from computer will give you more options than scan from the printer itself.
Regards.

PIXMA330 and new computer with Windows 8.1. Error Code 2,148,0 when trying to scan

I have a PIXMA330 and bought new computer with Windows 8.1. I get error code 2,148,0 when trying to scan. I tried to download updated driver but still have the problem. Is this common? Thank you.

You may have a BIOS problem, but there are no drivers for the BIOS. The BIOS is the system firmware. You will have to go to the support website of the computer/motherboard manufacturer to look for a BIOS update as Windows has nothing to do with
the BIOS - that is the sole responsibility of the computer/motherboard manufacturer.

i have a error of 0x80073715 on my computer when trying to download itunes. i have windows 7. i had itunes on my computer before. any ideas?

0x80073715
These ones are typically caused by underlying problems on the PC that also often cause Windows Updates to fail to install. If we can fix the Windows Update trouble, we can usually get the iTunes trouble cleaned up en passant.
Go into your Windows update and try to check for new updates. If updates install, stock up on the ones you're behind on, restarting the PC if requested to do so. After the restart, try installing iTunes again. Does it go through this time for you?
If windows updates fail to install, go into your Update History and doubleclick the failures. What alphanumeric codes appear for you? Are they also 0x80073715, or some other number? (If they're another number, what number are you getting?)

Why do I get the message "cannot get mail" when trying to connect to microsoft exchange server.

Why do I get the message "cannot get mail" when trying to connect to ms exchange server?

Hard to say. Has it ever worked? Maybe your account has mobile e-mail disabled. Maybe ActiveSync isn't set up properly on the server. maybe the correct ports are not open on the corporate firewall.
You will have to talk to your IT department.

Hi MACSRC1,
I see by your post that you are getting the error "secure connection to SMTP server could not be established" when trying to scan to email or fax. I can help you with this.
I have provided a document to check your scan settings. You might have to run the wizard again.

Click on Scan to email.
This document is for Cannot Send or Receive Faxes to go through to resolve the fax issue.

Some music and apps that I have downloaded from i-tunes "cannot be found" when trying to download them onto my ipod. Why is this happening when they are available on my computer?

Some music and apps that I have purchased and downloaded from i-tunes "cannot be found" when I try to put them on my i-pod. Why is this happening and what can I do about it?

In iTunes, select the audio book and righ click and select Get Info. Go to the options tab and click on Media kind and change it to Audiobook. It will then appear on the iPod under Audio books. On the iPod that is Muisc app>More>Audobooks.

"application cannot be found" when trying to open certain files

Recently i upgraded my computer to Mavericks recently and I've been having a problem opening certain files. In one day I upgraded to Mavericks and I also updated my Adobe programs to the Creative Cloud. Ever since then I cannot open any of my Adobe files. They are all saved as under the CS4 legacy format. I uninstalled CS4 after installing the Creative Cloud. Every time I try to open one of these files previously created in CS4, whether it is a photoshop ot illustrator file, I get the error message "The application cannot be found". I also can see no preview or thumbnails for the files. I talked to Adobe Support and we went through a process of deleting my preferences and it didn't work. I restarted my machine and it worked. It worked for a day and now after starting up my machine today it is saying the same thing again. After a while it just out of nowhere started working again. I'll be clear and say that I was logged into my adobe account and there were no network interuptions.
By the way, the new versions (Creative Cloud) of the adobe programs all work just fine and If I save something then it works fine. It is only when trying to read a file from a previous format.

If you are attempting to start Adobe Creative Cloud by opening a file created by its previous version, open the Adobe Creative Cloud app first, then choose Open from its File menu and select the old file. The files you are attempting to open were associated with the version you used to create them, which is now gone.
After opening them, save them again. From then on, opening them will probably open Adobe CC directly.

Getting message "file cannot be found" when trying to play music in iTunes

When trying to play ANY music in my iTunes Library I get the message that the file containing the music cannot be found. I recently updated to the latest version of iTunes - is this the problem or is it something else?? I thought that at least the songs purchased from the iTunes Store would play but they do not. I receive the same message which asks if I want to attempt to locate the file. I click yes and that takes me to the iTunes Library which gets me nowhere. Anyone have any ideas????? I have used iTunes for years with no problems before this.

Hi Patricia,
First, try Repairing Disk Permissions. Quit all open applications. Launch Disk Utility, it's in your Applications/Utilities folder. Select MacintoshHD 10.x.x in the panel on the left, select the FirstAid tab, then click Repair Disk Permissions. Only takes a few minutes to run, then Quit Disk Utility. Reboot your PBook and launch iTunes. See if you can play a track...
If not... with iTunes open, select iTunes Store, then from the Menu Bar, click Store/Authorize Computer and see if that works. If that doesn't work ...
Quit iTunes. Try dragging the com.apple.iTunes.plist file from the HD/Users/YourName/Library/Preferences folder to your Desktop. Launch iTunes and see if you can play tracks. If you can, drag that file back to the Preferences folder. If not, drag that file to the Trash, empty the Trash and reboot. It could be your iTunes preferences file is corrupted and needs replacing. Your Mac will create a new pref file for you the next time you launch iTunes.
Hope something helps...
Carolyn
