A "HP Twain Scan" function in the "Print and Scan Doctor" app - Solution?

Frustration!! Why can't I get the scanning portion of subject printer to work on my laptop Windows 7 (64-bit)!?? I've tried the Print and Scan Doctor several times, and the same dysfunction says "HP Twain Scan" whatever that means or is? I've pulled out the cords, all of 'em, and it still not helping.  Did I purchase a printer that is not compatible with my laptop? As far as the scanning portion is concerned, or what?  I can print OK, both from website/emails and my own documents.  I do a lot of scanning (photos mostly), and so this will be a sad problem.Hoping someone out there in techland can give me a solution. Thanks!

Hi , Welcome to the HP Forums! I understand that you cannot scan with your HP Envy 7645 on Windows 7. I am happy to look into this scanning issue for you! Some questions for you: Are you able to make copies with the printer? Copying Documents or Photos with an HP ENVY 5640, 5660, 7640 e-All-in-One, HP Officejet 5740 and 8040 e-All-in-One Printer Series.How is the printer connected? Wireless, Ethernet, or USB? In the meantime, please try the steps within this scanning guide, A 'No Computer Found', 'Connection Required', or 'Scan Unsuccessful' Message Displays for HP ENVY 5640, 5660, 7640 and Officejet 5740, 8040 e-All-in-One Printer Series, and let me know what happens! Hope to hear from you soon!  “Please click the Thumbs up icon below to thank me for responding.”

  • Can not add my new printer to the print and scan preferences

    I have purchased a Canon Pixma MG5350 and try to connect it to my mac but with no results. I have installed all the drivers but can not add it to the print and scan preferences. I looked in Applications > Utilities > System Information > USB and it does not even show that it is connected. The printer comes without a USB so I bought a 5m USB 2.0 A to B cable and eventually something is wrong. Is the USB too long, not the right one or what is the problem?

    I have already got my refund for the cable! I tried a friends cable and everything works!

  • When I receive, scan or print a .pdf, Adobe Reader shows a dark screen, so I can't see the doc.  If I print it, it usually prints correctly, but what happened to the print and scan preview screen?

    Problems with Adobe Reader (read my question)

    Try deleting the Adobe plugin and use the built in Preview. Hard drive level Library/Internet Plugins. If it isn't there, check your user Library.
    Quit the application.
    Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J.  When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder.  Select Library.

  • Trouble Printing or Scanning? Try the HP Print and Scan Doctor

    Are you having trouble when you try to print or scan with your Deskjet, Officejet, or Photosmart printer or All-in-One?  
    Does your print job get “stuck” and never come out of your printer?
    Are you getting an error message when you try to scan?
    HP suggests that you download and run the HP Print and Scan Doctor. While not all types of printing and scanning communication problems are addressed with this software utility, many common problems are resolved. This utility can be used to troubleshoot and in some cases directly fix common connectivity problems experienced with many of HP’s desktop printers and all-in-one devices when used on Windows XP, Vista, Win 7, and Win 8 systems (administrator privileges are necessary in order to run the utility).
    If the HP Print and Scan Doctor detects missing or incompatible software parts, the utility will offer to uninstall the current parts so that a subsequent reinstall process will go smoothly.  The uninstall / reinstall process usually resolves printing and scanning connectivity issues with a minimum of further fuss.

    Please Give HP Your Feedback!  If you use the HP Print and Scan Doctor, HP would like to hear from you afterward  – there’s a survey link built right into utility and it only takes a minute or two.  Your ideas on how to improve the Print and Scan Doctor help HP design new features and enhancements for all of our customers.  Thanks for taking the time to respond.
    Do you have a networked printer?
    If your printer is network connected rather than connected via USB, you may be experiencing network related connectivity issues.  Any network connectivity issues must be addressed first.  The HP Print and Scan Doctor will also check for and help you resolve network issues that previously required a separate utility (the HP Network Diagnostic Utility).  With the HP Print and Scan Doctor this is no longer necessary!  HP has combined all features of the Print Diagnostic, Scan Diagnostic, and Network Diagnostic utilities into our next generation utility!
    The HP Print and Scan Doctor runs on Windows XP, Vista, Win 7, and Win 8.  You will need administrator privileges in order to run the utility.

  • Scanner in use error message. Print and scan doctor page not found

    I have an officejet pro 8500a which is giving an error message: scanner in use.  it frequently does this and I reboot computer, turn off router and prnter and then turn all back on again and it usually works.  This time it won't.  I was directed to download the print and scan doctor but whether I enter the address in the url or click on the link I am directed to a page saying that it is not found.  What else can I do besides throw this through the window?

    Hello @trishdg and welcome to the HP Forums!
    Which operating system is on the computer you use the printer with?
    If you make a Copy (as that uses the scanner) do you get any errors that indicate the scanner is in use then?
    This Print and Scan Doctor link will start the download for you right away (meaning it doesn't take you to a page, that link starts the download as soon as you click on it ) so you won't feel the need to through anything out the window
    Let me know how those steps go, and we will go from there!

  • How to get Print and Scan Doctor to install in English

    The HP Print and Scan Doctor Utility automatically installs in the local language of the region and keyboard my pc is set for. How can I get it to install in English? 

    Hi John1000000,
    Welcome to the HP Forums. I see you are want to change the language in your Print and Scan Doctor. Here is the link to the Print and Scan Doctor, scroll down to the bottom of the page and there will be a spot right above About HP that will have your country. Click on the country and make sure that it reads United States. Then install it and let me know if you are getting English or if it is going to the regional language.

  • LaserJet software/driver issues. Print and Scan Doctor doesn't work on scanning function of MFP.

    Upon using the diagnostic utility HPPSdr. exe, only the select an action "Fix Printing" shows up and not the "Fix Scanning" option. Our printer is the LaserJet 3050 connected via usb running under Windows Vista32 on a HP dv8408us laptop. The scanning driver is HP imaging 4.0.4.0. There have been numerous problems with this scanning software/driver package which have been well illustrated on the HP forums. An update is sorely needed. All that HP customers really expect when we buy a product is that we get the functionality that we paid for and that we get support for the software and hardware for a reasonable length of time, I think that 5-7 years after the final production date of the product, at least, is reasonable. In the case of the 3050, the scanning has never worked right since day 1 because the scans are too light with signatures and time stamps showing up poorly. With the pnp driver installed it it almost impossible to scan in receipts, etc. The communication software Toolbox FX is needed to use the scan button on the machine, and since there are so many problems with this package with respect to system resource usage and connectivity, we can't use it and we don't get the walk up use of the scan button that we paid for originally. As Microsoft has updated the Windows OS, HP has failed to keep pace and we lose functionality of our equipment over time.  The diagnostic utilities have supposedly been updated several times and the scanning portion of the MFP still doesn't show. Surely the wide base of installation of this product could justify the expense of some engineering time for an update to the software and drivers. If HP hopes to turn itself around, a commitment needs to be made towards engineering products that really work in the environments that its customers use them, or else HP will merely be regarded as marketing company that is only concerned with selling the next thing without respect to customer retention.

    VisionAiry,
    Thank you for your response,
         There have been problems with the software and drivers for the LaserJet MFP/AIO machines which have been well illustrated by many users on here for several years. What is shocking is the unwillingness of HP to address these issues at an engineering and design level. This is the level in your organization that these problems need to be addressed at, not at the marketing and customer service level. The software/driver package has never really worked right ever since the 3050 - 3392 series was introduced back in 2006. The scanning drivers in the pnp drivers don't work, and never have, because of frequent communication problems. Someone never bothered to check if a blue ink signature would scan. I and several others have reported on these issues. What I have discoverd, through much trial and error, is that the full software package upon installation with only basic drivers installed using the check boxes in the menu, actually installs differently than the pnp driver. Who would have thought this? So now the machine scans OK. 
         My PC really appreciates not having the ToolboxFX installed. ToolBoxFX Error messages and crashes have been well documented on here. This is an application that puts an unnecessary drain on system resources. The only problem is that now the use of the Scan button on the machine is taken away so I don't get the walk up use of the scan button that we paid for in the original design. Why is the scan button function tied to the defective ToolboxFX software? 
         As far as printing goes, after carefully deleting the original print drivers, I use the PCL 5 and PCL6 UPD drivers. They work a lot better than the original print drivers ever did. But what about scanning? The scan driver on the 3050 dates all the way back to 7 2007. Scanning is an integral part of the functioning of most offices nowadays, but it is an afterthought at HP.  Why would a driver, software or diagnostic package only address half of the capabilities of a machine?
         When I went on the vacation recently, I tried to use my PCL 5 and PCL 6 drivers on my relatives 2009 OfficeJet 7310 and it wouldn't work at all. I had to spend 2 hours with multiple failed attempts to install the full 7310 package on my PC. Installation problems and repeated attempts are a constant theme with HP software. The very term Universal Print Driver is misleading because it won't work on many of the HP products out there. The product listing for the UPD, I only recently discovered on here, with help, because it was so buried on the UPD information page. 
         The LaserJet 3050 at $300 from Staples wasn't the most expensive printer out there, but it wasn't the least either. It is actually a pretty nice piece of hardware. I have invested over $1,500 in marked up toner since I've had this machine. HP needs to do better for us.

    Not using any mouse pad, I have a very smooth desktop. But I just tried to use a sheet of A4 printing paper, but no result, the problem persisted.
    Someone on this forum suggested, that USB3 may interfere with the magic mouse.
    I have 2 LaCie HDD's about 70 cm away from the mouse, I use them on Thunderbolt. But in operation or not - the result is the same, the mouse plays up! Just now I was clicking the desktop and the mouse created a new folder!!
    Thanks for the advice, Bee

    I have a wirless network. I connect all my computers to it and a printer. I can print wirelessly from all computers. I tried to add the printer to my new Macbook, which is connecte to the network, but can't find the printer on the add printer and scan icon on preferences. I downloaded a installation printer utility from the Manufacturer (lexmark), but it didn't work. Any sugestions?
    Thanks,

    You would need to get the IP address of your printer then manually add a network print queue.
    To get the IP address, on the control panel of your printer, press on Setup > Network Setup > TCP/IP > View/Set IP address.

  • PUT BACK THE MISSING THE SCREEN FUNCTION IN THE PRINT DIALOG BOX!!!!

    Hello all...
    I am a creative director in the screen print (garment industry) for over 20 years.  We have always used PS to directly print and control our halftone screens and angles through the screen function in the print dialog box.  Now it has miraculously disappeared after so many versions previous.
    I emplore Adobe and their team to please update this function back into CS5.
    Although it is a function many might not even understand how to use, it is IMPERATIVE to the screen printer/artist in this industry.
    There are workarounds, of course, but they are much more tedious and time consuming.
    I truly cannot convince enough that we folks in this industry want this function back!!!!!

  • How can I scan a photo from the printer and place it in i photo?

    How can I scan a photograph from the printer and place it in i photo?

    Scan the document as you normally would.
    Click Save and look for a format or option to allow you to save as a JPEG file. (The normal format is probably set to PDF)
    Seve to your desktop location or to a scanned items folder if you normally scan to that desitnation
    Drag the JPEG file onto the iPhoto icon on the dock and release the mouse key
    Once you have imported the image into iPhoto, you can delete the file on your desktop or in the scanned items folder if you prefer

  • Scan scan bar on the printer is continuously moving back and forth.

    The printer is connected via USB to a computer using Vista and also used remotely by a MAC, IPad, and IPhones. 
    The scan bar on the printer is continuously moving back and forth, I ran the HP Print Scan Doctor and it found no problem. 
    I can print, copy, and scan but the motion of this piece on the device will not stop. 
    No change to the issue occurred when I turned the printer off, waited several hours, and turned it back on. 

    Hi @GGx3,
    Welcome to the HP Forums!
    I noticed that the scan bar on your HP Officejet pro 6830 printer is continuously moving back and forth. I am happy to look into this scanning issue for you!
    First, I would recommend a hard reset, by going to this post, How to perform a Hard Reset, by @Rich1. it is important that the printer's power cable is plugged directly into the wall outlet, and not a surge protector. Please, see this article, Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector for more information. This applies to Inkjet printers as well.
    After the hard reset, I would go through this guide, The HP Printer Does Not Turn On or Respond When the Power Button is Pressed, and watch this video:
    (Even though the guide title may not match your issue, I believe the solutions will help.)
    The last step I would do is to also make sure your printer's firmware is up-to-date. Getting Printer Updates for HP Officejet 6810 and Officejet Pro 6830 e-All-in-One Printer Series.
    Hope this solves your problem, and have a good day!

  • HP Solution Center stopped working and HP Print and Scan Doctor cannot find my OJ4680

    HP Solution Center came installed on my HP G60 notebook with Windows 7 premium 64 bit.  It suddenly stopped working--it says it cannot run because the device installation is not complete.  If I open HP Sup0ort Assistant it says the OJ4680 is ready and it is designated as the default printer in Printers and Devices but when I try to run HP Print and Scan Doctor it cannot find it--it can only find OJ4500 which I use when I'm in my second home.  Please help me fix this as at this point I can't print or scan. 

    Thanks for the help and quick response.  I haven't tried your solution yet because before I received your instructions I updated the drivers again and it appears to be working though I've had a message since then that I couldn't scan because my device was offline which was not true as I had just printed a document.  I used HP Print and Scan doctor and followed the steps which included turning the device off and unplugging it for 60 seconds.  I can now copy, print and scan but I still have the yellow triangles with exclamation points on both my PC and all in one.  I'm not sure I want to do more at this point since everything is working well at the moment. BTW my laptop is set for automatic updates by HP and Microsoft, why didn't they keep this problem from occurring?
