Unable to scan----no computer found

I have recently switched internet providers. My wireless box is downstairs and I have a router-repeater between it and this computer (a Mac). I've had no troubles with scanning until this change was made. In trying to scan I see the message "no computer detected). I've tried identifying the wireless router as both the original box and the repeater. The wireless network test report says "No problems found. Congratulations on the successful setup of your wireless printer" The HP Network Configuration Page says the Netowrk Status is "Ready" and the Active Connection Type is "Wireless". Yet every time I hit 'scan' the message comes up that no computer is detected! I've tried switching the printer/scanner off and on again. I've tried unplugging it. Nothing has worked. Help!!!
This question was solved.

Hi Sophia21,
I understand since you changed internet providers the printer won't scan. You have a wireless box downstairs and a router-repeater also. I can help you, but I will need some more information to assist you better.
Is the printer connected to the main routers network name?
In the mean time you can do the following steps:
Repair the Disk Permissions on the Mac:
Close all applications.
On the Apple menu bar, click Go, click Applications and then click Utilities.
Double-click Disk Utility.
Highlight your hard drive/partition on the left.
Click Verify and then Repair Disk Permissions.
Restart the computer.
Reset the Printing System:
Note: This will remove all printers in the print and Fax/Scan, any printer removed can be re-added later by clicking the plus (+) symbol.
Click the Apple icon ( ), and then click System Preferences.
Click Printers & Scanners.
Right-click (or Ctrl +click) in the left white side panel, then click Reset printing system.
Click OK to confirm the reset.
Type the correct Name and Password.
Click OK to reset the printing system.
Then click the + sign, then select the printer from the list and click on the Add button.
(make sure it shows the printer name beside Use, not the Airprint driver)
What operating system are you using? Mac OS X: How Do I Find Which Mac OS X Version Is on My Computer?
What kind of router do you have?
What is the full name and product number of your printer? How Do I Find My Model Number or Product Number?
Have a nice day!
Thank You.

OfficeJet 4630 enable scan to computer error

I just purchased the Officejet 4630 yesterday. I am able to print but unable to scan to computer. When trying to enable scan to computer, it never completes the task. I have followed the troubleshooting guide including repair disk permissions. The driver is the most recent.

Scanning to Computer, HP Officejet Pro 8500 Wireless All in one Printer A909g

I am unable to scan to computer with Win 8.1 using my HP Officejet Pro 8500 Wireless all in one Printer A909g. I can scan to email. The system says my drivers and software are up to date. When trying to scan to computer all I get is a blank scan file with no scan number (Scan_Doc0054) as I used to with Vista. In Vista I was able to drive the whole process from my computer. When scanning to email now I have to drive it from my printer as opposed to the computer.
I restarted an old computer running Vista and the 'scan to computer' function is operational. As far as I am aware there are no other functional problems with the printer.
Any help would be very much appreciated. Thank you.

Hi John046,
I am sorry to hear that did not work for you, I do have some more options for you to try:
Uninstall the software. Uninstalling the Printer Software.
Clean boot the computer. How to perform a clean boot in Windows.
Disable any antivirus programs. Windows Defender - Turn On or Off in Windows 8.
Disable any firewalls. Disable firewall Windows 8.
Re-install using the HP Printer Install Wizard for Windows.
If that does not resolve your issue, please call our phone support at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region. Country-language selector.

HP Photosmart 5510 unable to scan from panel or computer using Windows 7 64 bit.

I've uninstalled software 3x and reinstalled using driver from HP's website. I've already gone through the HP Diagnostic tool 3x. Windows (WIA) Scan and HP Twain Scan always come back with error messages. Through their messages, we have uninstalled and restarted computer numerous times. Scan to Computer is enabled. Wonder if the printer is faulty.

Have you tried restarting the following services:
Remote procedure call
Shell hardware detection
WIA
If not, let me know and I can tell you how.

Unable to scan and communicate with scan function C6180 Vista Home Premium 64 bit Printing works

I have an all in one C6180 Photosmart connected by wireless network (infrastructure). Network consists of 2-laptops, 1-Desktop and the printer. Everything works from HP solution Center on the Compaq laptop and the Dell desktop both running Windows XP. My newest laptop is a Dell studio XPS core2 2.4ghz running Windows Vista Home Premium 64 bit. I am unable to scan from the Dell Laptop using HP Solution Center nor can I scan from the printer buttons to the laptop. Solution Center opens I select "scan document" and immediately get an error message "unable to communicate with scanning device. Likewise with the copy function. The laptop does recognize the printer though and I am able to print wirelessly. All functions work when connected via USB so I believe the printer is fine. I have been working with this problem since I bought the printer in 2007. I spent many hours reading hundreds of internet posts, talking by phone with HP and via e-mail support from HP. I became frustrated and gave up for awhile but now I want to see if there are any new solutions that I don't know about. I downloaded full feature software and drivers for the 6180 from HP and performed various levels of uninstall (L1, L2, L3, L4). I also cleaned the registry with ccleaner, windows disk cleanup and manual registry deletions when allowed per HP. I have checked port settings, tried stopping HP functions is Services.Msc. The Digital monitor is currently running, however no scanner communication-computer to 6180 and no scanner communication 6180 to computer. I can print and fax from computer wirelessly. I have ran the HP diagnostic utility separately and it appears everything is fine, connection IPaddress etc. During install when prompted to run test it says the printer is connected to the network. I have tried to add a device to the network after install and get the message no wireless devices found. The scanner does not appear under Cameras and Scanners in control panel. Nor will it find the scanner when I try to add device. Firewalls and antivirus have been turned off. Still can't make it work. Suggestions please.

Sorry about your pain. L3 uninstall is what I recommend. Re-install from hp.com and this time, with the printer properly attached it should flow OK.

Scan to Computer problem HP Officejet Pro 8500 (A909a) OSX 10.7.5

Good afternoon,
First of all I appologize if this question already has been asked a thousand times, but I am unable to find a solution in the somewhat simular stories. But reading thru all off them, while English is not my native language, was beginning to wear me out.
My set up is as follows:
- HP Officejet Pro 8500 all in one - A909a
- 2 iMac running with 10.7.5
One can be selected using the "scan to computer" and the other can't. Both have identical systems, the only difference is the one that can not be found by the printer is the one that has done all the available updates.
So far I have done an "repair permissions", looking for additional updates and finally an uninstall of the software. I installed the programme HP_Installer_Officejet_Full_Group05_10.6.dmg (which I believe is the one that came with the printer) after which it all works again. So problem fix I know... but when checking for updates using the Apple update, there is an update waiting for me and when I run that one, that computer dissapears again from the "scan to computer sellection).
For now I am keeping the update sitting in the Apple Update and happily use all the functions, but I am curious (and a bit OCD with the fact there is an update hahaha), can I ever have my software up to date without having to loose that function? Or is there another update/fix I can try using the up to date software?
Thanks in advance for any response!

Welcome to the forums, I hope you are well
I noticed your post and have read it thoroughly. My first question to you is, what is the update that is waiting? I would like to know about the update before we continue.
Please let me know and I will gladly look into this some more for you!
Best wishes,

HP ENVY 5530 no computer found

I bought my HP ENVY 5530 about a year ago and have not had any problems with it until now. I keep trying to print stuff (word documents, photos, emails...) and nothing happens. No messages come up on the printer. When I click on the printer icon on the computer it the status says 'Printing' but soon changes to 'Error'.I tried to scan something to the computer and the printer says 'No Computer found'. How do I fix this??

Alright here's what we'll do.On your PC click on Start.In the box that says Search Programs and Files type in Services and press enter.In this window click on Component Services (Local) on the left.On the right side click scroll down to Print Spooler.Right click on Print Spooler and click on Stop.Open Computer and go to C:/Windows/System32/spool/printersDelete everything in this folder.Go back to where you right clicked on Print Spooler, right click on it, and click on Start.Try printing.If you are still unable to print or scan then the next step would be to uninstall and reinstall the drivers for your printer. You can find the latest drivers by clicking on this link. I hope this helps and I hope you have a great weekend!

C309 won't scan to computer

I can no longer from my C309 to my laptop. Starting the scan from the computer does not offer me a pdf option. I have recently bought a new laptop (a Dell) after experiencing the same problem with my previous laptop (a Toshiba). At first the scan from computer worked with the Dell but has now stopped. This seems to have been a common problem with the C309, but the solution I found on the forum does not work for me. For some reason my HP program folder contains neither the HP309 program identified in the solution nor the HP Service Center identified in another piece of on-line advice. SHould I buy a new printer/scanner (which will not be from HP!)?

8620 won't scan to computer

My printer will not scan to my computer. I have gone into the hp utility app and trie to "enable scan to computer" and it says "The HP software required for Scan to Computer could not be located on this computer. Please download and install the latest HP recommended software for your device from http://www.hp.com/support, and then try again." I have followed the link and re-installed my software twice and installed hp scan too but it still wont let me scan to computer. I have the absolute most recent software and it still tells me scan to computer cannot be enabled. Please help me!!

Hello mcason5,
Regarding the 8620 not scanning into the Mac 10.10, I would like to see if I can help. I assume that you are using Wireless connection, is that correct?
I dug up some scanning troubleshooting steps you can try: A 'Computer Not Found' or 'Connection Error' Message Displays for HP Officejet Pro 8610, 8620, 8630,...
Give those a try and reply back with the results.

HP 7515 won't Scan to Computer

i'm using Windows 7 Home Premium 64 bit and an HP 7515 All in One. When I originally setup the printer, whenever I rebooted the PC a window would pop-up asking to enable Scan to Computer. That no longer happens. When I attempt to Scan to Computer from the printer the message on the printer directs me to Enable Scan to Computer via the printer software when using wireless printing. Unfortunately the printer software does not provide that option to select. When I use the HP Printer and Scanner Doctor it repeatedly tells me to remove power from the printer, restore power and reboot the PC. That does not fix the problem. When I try downloading a new driver (7510 series as 7515 is not available) the HP software indicates I am not connected to the internet when in fact I am.

Hi @jimalo,
I see by your post that you are unable to scan. I can help you.
