HP Scan (Officejet Pro 8600) reports an error

I'm having several problems with scanning. I am using HP Scan Version 4.4.1 (21) on a MacBook Pro running Mavericks - 10.9.1. This is installed as part of the v12.34.37 Mac OS Driver/Application Suite for Mavericks.
1. Scanner reported an error (An error occurred during scanning.)
This occurs having selected 'Scan' from the HP Scan Menu, I then select Type, but only have the 'Automatic' option available to me.
2. I no longer have access to change settings on the Scanner Presets Menu. I can't select any of the options (Source, Orientation, Mode, Resolution, Crop to) and I also seem to have lost the 'manual' double-sided option (which alongside the lack of twain driver was a shocking omission from this model, and an enormous dissappointment).
See the image below: -
3. Scan to computer (scanning to PDF or JPG)
Having selected a computer from the list, the scanner is unsuccessful. The error message is: -
Scan Unsuccessful
The HP Scan dialogue briefly appears on screen and displays the message 'Preparing to Scan'.
The scan could not be completed due to one or more of the following issues:
- Connection to the computer is lost
- The scan application on the computer is currently in use
- OCR application is not installed on the computer
See the computer monitor for details (there is no information on screen).
I can scan from the webscan applicaiton, and eprint is configured correctly if that has any bearing on the response!
I hope that this is enough information to get the problem diagnosed/solved, but if not, please let me know what else you need!
Thanks!!

Hi,
I've got around to runing the tests you recommended.
The power cycle did not work.
I then ran the troubleshooting from the recommended link for Mavericks which is what I am running.
Solution one: There are no other users using the scanner, just one connection from my computer.
Solution two: Scan to computer checked, and printer sharing switched on. Still no scan.
Solution three: Repair Disk. This resulted in the following: -
2014-03-02 15:41:07 +0000: Disk Utility started.
2014-03-02 15:44:11 +0000: Repairing permissions for “Macintosh HD”
2014-03-02 15:44:20 +0000: Group differs on “Library/Printers/InstalledPrinters.plist”; should be 80; group is 0.
2014-03-02 15:44:20 +0000: Permissions differ on “Library/Printers/InstalledPrinters.plist”; should be -rw-rw-rw- ; they are -rw-r--r-- .
2014-03-02 15:44:20 +0000: Repaired “Library/Printers/InstalledPrinters.plist”
2014-03-02 15:45:51 +0000:
2014-03-02 15:45:51 +0000: Permissions repair complete
2014-03-02 15:45:51 +0000:
2014-03-02 15:45:51 +0000:
This did not solve the problem.
Solution four: Uninstall and reinstall the software. The scan to computer feature is still not working.
I am still without a working scanning feature. I may look at returning the printer and exchanging it for a different make or model - this is harder than it should be.

HP Officejet Pro 8600 Network connection error message in EWS

I just got an Officejet Pro 8600 Premium. The printer is connected to the network via a network cable. When navigating through the EWS, sometimes the message "Network connection error. Check network and try again." message is shown (the message could appear in various pages, such as Settings, Tools, etc.). Refreshing the page should get rid of the message.
At first, I suspected if it was a problem with the network. So I pinged the printer's ip address continuously. It did not miss a single beat. The printer prints and scans well via the network. So I think the error may be caused by something inside of the print, such as bug of EWS software, or internal error.
Anyone see the same message during the use? Any suggestion? Does it indicate there is hardware problem with the printer? Thanks.

HP Support has escalated the case. I referred this thread in the support request. Hopefully, they can have a look at the issue.
For me, the only setting does not stick is "Use the same time zone set on this computer" in Settings\Date & Time. I've created another ticket for this issue. 8500A has the same problem.
You can try to restart the EWS. Unplug the power cord while the printer is on. Then wait 15 sec and reconnect the power cord. Press the power button if the printer does not turn on by itself.
If you would like to reset to the printer and reconfigure from scratch, you can check here: http://h30434.www3.hp.com/t5/Printer-All-in-One-Install-Setup/How-to-reset-Officejet-Pro-8600-Plus-P...

Hi @Benking116 and welcome to the HP Forums
I'm sorry to hear you've been having issues scanning from your Officejet 8600 to your Mac running OS X 10.10 but I will absolutely do my best to help!
If you open HP Scan on the computer, are you able to scan from there without issue (please refer to this Scan from OS X With the Full Feature HP Software document to see how to open the HP Scan software)? If so, I believe you just need to Enable Scan to Computer within the HP Software. Please have a look at this Re: Scan Definition post and it will advise where to go in the HP Utility to choose Enable Scan to Computer. After that is done are you able to from the printer to the computer?
If you're UNABLE to scan via the HP Scan software, the issue could just be communication itself. In that case, please try the steps within this Printer Does Not Maintain Wireless Connection document.
Let me know how things go for you

Officejet Pro 8600 Plus - Apps Error - 'Connection Error'

Hi,
Newbie question maybe, but it's got me a little stumped.
I've an HP Officejet Pro 8600 Plus on a wired connection to my Sky router/ADSL modem, using a static IP.
when I go into Apps it pulls down a list of the installed Apps OK, but when I select any one from the printer control pad it tries to connect then throws an error. I can;t see a place I should set anythign up.
I have a woerkign hp ePrint Center account, ePrint works (eventually!) when I email docs to my eprint email address, adn also via Google Cloud Print and Apple AirPrint. While it;s not ruining my life, I would like all of the printer functions to work :-)
I can print to a network folder, as long as it;s on a PC, although my NAS it won;t print to for some reason, but I guess that's a further question :-)
Any help very much appreciated!!!!

Hi MF668,
Try setting an alternative DNS and check if that may help:
Press the wireless icon on the top of the printer screen and locate tis IP address.
Browse to the printer's IP through the web browser on your PC.
Click the Network tab.
Under Wired click on IPv4.
Under DNS Address Configuration select Manual.
Set the Preferred address as 8.8.8.8
Set the Alternate address as 8.8.4.4
Click Apply to confirm the change.
Now turn the printer Off and back On and check for any difference.

Officejet pro 8600 plus. Error message: cartridge missing or damaged

Just installed a new printer head to the tune of $120.00. It came with set-up cartridges that you are required to use. Installed new printer head and cartridges. Now I get the error message of cartridges missing or damaged. I have taken out the cartridges and printer head about 5 times and still get the message. Do I dare try using my old cartridges (which were actually brand new - more $ wasted)?? how can I run a business without a printer, scanner, and fax?!?

I'm having the same issue. We also had this issue with the original 8600 we purchased (that one only used the demo cartridges before giving the lovely "cartridge missing" error). The first one was still under warranty, so we had to send it back to HP and get a replacement. In the meantime, the office was without a printer. Now, the second 8600 has managed to last through about 8 cartridges (approximately six months) before the same issue arose. It's even with the same cartridge: magenta.
I've changed cartridges, removed the print head and cleaned it, cleaned the contacts on cartridge, the print head and even where the print head connects to the printer, and even removed the little white plastic guide wedges and switched them around to try and troubleshoot the situation. I've rebooted it repeatedly and briefly contemplated banging it vigorously on the sides to beat it into submission.
Alas, it is still showing the error.
I wish I could say I'm a novice when it comes to troubleshooting, but I regularly work on printers and other components. It is truly frustrating to have a product which does not perform well and which does not easily allow the user to rectify the situation without resorting to a sledgehammer or wine.

Officejet Pro 8600 print cartridge error

one or more cartridges appear to be damaged K. Message appeared after replacing the exhausted original black setup cartridge. I replaced the replacement cartridge with a new cartridge to no avail. I cleaned the contacts and even replaced all the original setup cartridges, again to no avail. This is a wireless network printer and the PC uses a windows 7 home premium OS. This appears to a printer problem not connected to the PC or OS. This is the 2nd HP printer i have that has the same problem. Any suggestions except replacing the printer?

@ REBjr. - I understand that you are getting error message on the printer that is related to the print cartridges. Are you using genuine HP non refilled ink in the printer? I would start by doing a hard reset to the product in an attempt to restore the printer to a known working condition and try to clear the error message prior to replacing any parts. Here is a document that will provide the steps to the hard reset. Also, is there residue on the black cartridge? If so, I would look at this link here. It addresses getting an ink cartridge error message on the printer when trying to install a new black cartridge in the machine. I hope that this helps.

Configuring "Scan To E-mail" on HP Officejet Pro 8600 Plus N911g

This is the same issue reported by several other users in this forum to which no solution has been provided.
I have been unsuccessful in setting up the scan to e-mail option for a HP Officejet Pro 8600 Plus N911g purchased on August 12th 2012 and using the firmware CLP1CN1150CR.
I am trying to do this through the Embedded Web Server interface to the printer from an iMac running Mac OS X 10.6.8 and HP Utility 5.8.0. More specifically the page under "Scan -> Scan to E-mail -> Outgoing E-mail Profiles".
I have tried 2 different SMTP outgoing servers, each of which works well to send e-mail from the computer: Apple iCloud e-mail service (formerly known as Mobile Me, formerly known as .Mac) and AT&T Net e-mail service. I verified that the server name, port number and authentication login/password values were all correct.
When scan to e-mail is used from the printer, I get an error message: Cannot connect to server. Check server name and address.
When tested from the computer during the setup of an outgoing e-mail profile, I get an error message: The device could not send the test e-mail message. (EmailAccounts-timeout).
When I try to configure the page under "Settings -> E-mail Alerts -> E-mail Server" and use exactly the same values as the ones in the outgoing e-mail profile above, the Save and Test option fails with an error message: The device could not send the test e-mail message.
Interestingly enough, I am able to use the computer's e-mail client with the option Scan To Computer -> E-mail as PDF or E-mail as JPEG. With this option, the file is scanned and added as an attachment to a mail message from the Mail client under Mac OS X. When I press the Send button, the e-mail is sent successfully through the same SMTP server.
All the error messages seem to indicate that the printer's e-mail client software is unable to establish a connection to the SMTP server. However, it is not clear what configuration parameter is the one that could be causing the problem.
This question was solved.
View Solution.

After further research, I noticed that there are other possible default Simple Mail Transfer Protocol (SMTP) port values:
Port 25 is the standard SMTP port number.
Port 465 is the port number for SMTP over SSL, Secure SMTP (SSMTP).
Port 587 is the dedicated port number for a Mail Submission Agent (MSA) that uses a variant of the SMTP, as specified in RFC 6409, which requires that clients are authorized and authenticated to use the mail submission service.
I had been using port number 25 as this is the standard one. However, all tests were failing. Hence, I decided to try the tests with ports numbers 465 and 587.
Port number 465 failed with the same errors listed above. However, the tests passed with port number 587. After saving the successful configuration with port number 587, I tried the scan to e-mail option from the printer and it worked.
A mail submission agent (MSA) is a computer program or software agent that receives electronic mail messages from a mail user agent (MUA) and cooperates with a mail transfer agent (MTA) for delivery of the mail.
Historically in Internet mail, both MTA and MSA functions use port number 25. However, many Internet Service Providers (ISPs) and enterprise or institutional networks restrict the ability to connect to remote MTAs on port 25.
With a dedicated port 587, it is always possible for users to connect to their domain to submit new mail. Availability of a MSA on port 587 enables nomadic users to continue to send mail via their preferred submission servers even from within others' networks. Using a specific submission server is a requirement when sender policies or signing practices are enforced.
I know that many users may find the technical details boring or confusing, but I just wanted to include some background to those who actually care about this level of detail. I also wanted to provide a possible solution to other users who are experiencing the same problem.
So, in a nutshell, if the Scan To E-mail option is not working for you using port number 25, then try one of the other SMTP port numbers listed above. If none of them work, check your mail provider for other possible outgoing server port numbers.

Officejet Pro 8600 e. Problem scanning from Scan and Capture App in Win 8.1

Officejet Pro 8600 e. New.
Installed on HP Envy 23 Touch. Running Windows 8.1.
Wireless set up. Prints fine. Problem is scanning from the HP Scan and Capture Software App in Win 8.1
Using Scan and Capture App I can scan photos fine. They come out clear. Scanning documents in GRAY has multiple bands/lines in gray over the entire page running vertically. Scanning documents in COLOR are fine.
Also, if I scan from the printer directly using the touch screen on the printer, the scan output is fine.
I did the Scan utilty to discover any errors and it did not show any. I think it's a software error. I am going to uninstall the HP Scan App and then reinstall. So, I will do the uninstall/reinstall and report back.
Also, I would like to know if there is a desktop program for scanning? I would prefer to use that instead of the Modern HP Scan and Capture App.
Thanks....

Hi artrum,
I understand you've been experiencing issues scanning from your Officejet 8600 using the Windows Scan and Capture program. I will certainly do my best to help you with this!
From what you've explained, I believe you're correct, it does seem like it's an issue just with the Windows Scan and Capture program and as you've been able to scan from the front panel of the printer you definitely have the HP software installed. What I'd like to do is have you use the HP Scan software, where you should no longer run into issues.
To access the HP Scan software and be able to access it easily from your desktop I'd like you to follow the steps below:
1. Go to your start screen and just start typing File Explorer. You should be able to then open it to access your computer's files.
2. Then open Local Disk (C: ), followed by Program Files (x86), followed by HP, then HP Officejet Pro 8600, followed finally by bin.
3. In the bin folder you should see HPScan. You will want to right click on HPScan and go to Send To and then select Desktop.
Now you should see HP Scan on your desktop and be able to open it and scan through that application.
Hope this helps, have a great day!

HP Officejet Pro 8600 Premium will not copy or scan.

Hello,
I have a HP Officejet Pro 8600 Premium that prints just fine however it will not copy or scan. When I attempt to copy a document it displays Starting Copy... on the printer but will not copy and must be turned off and on to use the printer again. When I attempt to scan it brings up an error box telling me to check all of my network connections.
I have already tried the services.msi fix and have ran hp printer and scannor doctor tool to attempt to fix my problem.
In the services.msi I found that all services dependant on (WIA) were already running and set to automatic.
The scan doctor found that It wasn't communicating with the drivers, which I then reinstalled, and restarted the computer. It then continued to have problems with the drivers and asked me to contact support.
Thank you for your time.
edit: The printer is also running the latest firmware and I have also checked my anti-virus firewall so that it is allowing the printer through network. (note: in attempt to fix the issue i have both a usb and network connection trying to get either connection to work).

Hi-
To make sure I understand this correctly, you are unable to do a copy at the device itself? This should function without the device being connected to a PC at all. if this is indeed the case, it sounds as if this is a hardware issue. I would then check with HP support on your product for warranty repair.
I am an HP employee, however, this content reflects my personal opinion and is in no way associated with HP.

Scan To network folder - HP officejet pro 8600 cannot connect.

Good morning,
For the last week or so, My officejet pro 8600 has been giving me the error
"Cannot connect to \\REDACTED\Public\Scans. Make sure the remote computer is turned on."
It will correct itself if we restart the computer/printer in question. but this only solves the issue for approx 6-7 hours.
Things i have done to attempt to fix this.
Set a static ip address for both the computer in question and the printer itself.
updated the IP address using the HP tool.
reinstalled the HP office program.
Set DMZ for both the computer and printer.
Set the public scans folder to zero security( so anyone connected to the network can gain unrestricted access)
re-setup the network feature on the printer itself.
however now i am at a loss.
Any help would be great.

HP OfficeJet Pro 8600 Plus - "Scan to Computer" issue on Mac OSX 10.8 or 10.9

Hi...
I have started experiencing the notorious "scan to computer not working" issue on my 1-month OfficeJet Pro 8600 Plus, after having used the feature a number of times flawlessly.
There are a lot of potential solutions mentioned in dozens of relevant posts for both Mac and Windows, e.g.:
"Failed to open a session on the device"...
Scan to computer does not work...
Problem scanning to computer with an 8600 wireless
Unable to enable print to computer...
Enable Scan to Computer - Communication Error
Officejet Pro 8600 Utility does not show my Mac computer in scan settings
A 'Connection Error' or 'No Computer Detected' Error Message Displays during Scanning
HP Wireless All-in-One Printers - Communication Error between the Scanner and Your Computer...
Etc.
However, in my case, no solution works, after several frustrating hours of trying to fix the issue, in Mac OS X Mountain Lion (10.8), or after upgrading to Maverics (10.9).
The behavior of the device points to a software issue, since:
The printer is visible on the network
The print function has been working fine
The HP Scan function works
The generic Scan function from System Preferences works (although in earlier times it did not, or it stopped working soon after invoking it)
The "Scan to Computer" option does not appear in the HP Utility screen (although occasionally, after random sequences of unistalling and installing the software, it reappears)
The HP Installer crashes before completing the installation (this is a latest symptom, apparently happening before unvoking the HP Setup Assistant, which still works fine)
As already mentioned, I have tried all possible solutions, including software and firmware updates, Apple drivers, HP drivers (full featured software), clean (un)installations, followed by computer and printer restarts. Nothing seems to work.
The "Scan to Computer" feature of the 8600 always works on my Windows 7 laptop, after initial configuration.
The next step will be returning the device for a refund, but before resorting to that, I am giving it a last chance, in (the unlikely) case there is something new I have not tried yet.
Thanks,
PNS

HP OfficeJet Pro 8600 - will print wirelessly but not scan on Windows 8.1. HP PC

Hello,
my HP printer and HP computer have been working perfectly but now all of a sudden I cannot scan anymore from my printer to my computer. I can print and scan the other way around and the wireless network works. I am just a regular user and don't feel sure about how to uninstall and re-install programs, so I would be very happy if you had just a simple fix
I already tried closing down everything and unplugging the router, then plugging the router and turning everything on again but it didn't help.

Officejet Pro 8600 Plus won't print or scan wirelessly using Mac OS 10.

Mac OS 10.9
Wireless
My printer was working fine until today. Then when I used the control panel to scan a page I went through the steps and got to scanning and got the message I needed to enable "Scan to Computer" in the HP Utility. I went there and it was unchecked. Seems I had this problem every time I did a new scan job in the past. It wouldn't retain than check. So I checked it and after awhile I got the message "Communication Error" and to check my connections and if that didn't work restart my computer and printer. I did that and also restarted the router but it didn't help.
Then I tried printing from Word, which has always worked but it didn't this time. The printer icon on the right of the dock came up, bounced a few times then disappeared with nothing happening on the printer.
So I deleted and reinstalled the printer. No help. I downloaded and installed HP software and firmware updates. No help. I went through wireless setup. No help
BTW, all along I got good "Wireless Network Test" results. I says it's connected but nothing happens when I try any functions of the printer.
If I can find a USB cable I will try to see if wired works.
Any suggestions would be appreciated.

Hey @neoflyer,
I would like to assist you today with resolving the wireless printing and scanning issues you're experiencing on your HP Officejet Pro 8600 Plus e-All-in-One Printer on your Mac OS X 10.9 Operating System. You mentioned that you have powercycled the devices, reran the wireless setup, and uninstalled and reinstalled the software and drivers to no avail. I'm going to suggest a few additional troubleshooting steps to verify if this is a computer issue or a network issue.
Step 1: Gather the IP and Open the EWS:
1. On the screen of your printer select the wireless button:
2. Under the Wireless information you should see your IP address
3. Open up your internet browser on your Mac computer and in the website address bar just type in your IP address. Please do not include www.
4. After you enter your IP address in the website bar go to that website
5. If the website for your printer opens than that proves with 100% certainty that your printer and computer are 'talking' to each other on your wireless network. If the website fails to open than you have a network communication issue with your router.
If the website fails to open please powercycle your network again:
How to Properly Powercycle a Network:
First, unplug the power cable to your Router
Once your Router is unplugged, turn off your printer
Next, shut down your computer
After 30 seconds to 1 minutes, plug your Router back in
Next, turn on your printer
Turn on the computer
After a few moments check on your computer and ensure that the internet is working. Once it is, hit the wireless button again on the printer to see if your printer got a new IP address. Using the IP address enter it in the address bar of your internet browser and now see if the website for the printer opens.
If the website for the printer opens successfully please follow the steps below:
Step 1: Uninstall Drivers and Software:
From the computer desktop, double-click the Macintosh HD, and then click Applications.
Click the Hewlett-Packard folder.
Double-click the HP Uninstaller, and then click Continue.
Select the product to uninstall, and then click Uninstall.
When prompted, type the Administrator name and Password, and then click OK.

HP Officejet Pro 8600 e-All-in-One printer - N911a - Cannot scan

Hi Support,
I am getting very frustrated with my new printer. Now I have searched this forum and tried this and that, installed and uninstalled and run misc. HP tools, still I cannot use the "HP Scan" program from the PC and also not the "Scan to Computer" option from the printer.
I get an error message saying that "HP Officejet Pro 8600 was not found".
I am able to scan to a networkfolder - and printing is also possible.
I have activated every setting in the EWS admin module to be sure.
I have checked that these services are running (was mentioned in another support ticket):
- Remote Procedure Call RPC .
- DCOM Server Process Launcher
- RPC Endpoint Mapper
- Shell Hardware Detection
- Windows Image Acquisition (WIA)
and they are - so that is not the problem.
When I run the "HPPIW.exe" (Printer Install Wizard) downloaded from support - it says that the full installation is there except the drivers.
System info:
HP Officejet Pro 8600 e-All-in-One printer - N911a
Windows 7 Home Premium 64-bit
Product CD - holds driver version 24.2.0 ( which also is the latest version that I can download.)
Please someone help me, I was expecting to be able to use the product that I bought ;O)
Thanks,
Thomas, (Denmark)

Hi fogh,
Make sure that the firmware is the most current version, and then install the printer using the software from the link below. If you still have an issue I would suggest installing the printer on a different computer to help isolate the problem. Let me know what you find out?
