Hi @edheubach,

Thank you for your participation in the Forums of HP Support! It is a great location to get resolutions and interact with experts from the community. I understand that you have problems scanning with your printer "HP 2540". I'll be more than happy to help you with this.

You did a great job on the problem on your side. Kudos to you on this point. It is always a privilege to work with technical specialists like you. I see that you've tried to reinstall the printer software and also I tried to scan the printer and the software of the printer also. You can also run the utility of doctor print and scan. Brilliant work.

To help you better, I need the information about it. Please let me know the operating system of the computer. Please let me know the type of connection. Is it connected via a USB cable or is it wireless?

Please do a hard reset of the printer. To do this follow these steps:

  • Disconnect the power cable from the printer to the back of the printer.
  • Press and hold the power button on the printer for about 20 seconds to carry out the static electric charges built into the printer.

Then turn on the printer and try to copy the printer. Do not use the scan from the printer function. Please check if the printer copies fine. If it isn't, then the problem is hardware related, and you have to get the printer serviced by contacting support phone hp by visiting this link: http://hp.com/contacthp

If it copies very well so we can correct the problem by changing some settings of the firewall on your computer.

If it is a USB connection, make sure that the length of the USB cable is not longer than 6 feet and follow the link given below for further troubleshooting. If this is a wireless connection, please go to the page of the EWS of the printer on your browser by typing the IP address of the printer and try to scan from there. If it does not scan, please disable the antivirus firewall and check if it scans. (Mcafee or Norton)

I will include some links for troubleshooting issues on your printer scan if it's a USB connection. Please see these links.

  • HP Deskjet 2540 don't Scan

    Hello

    I just got this today.  Prints fine, but it doesn't scan.  I've tried printing & scanning doctor several times, but it will not solve the problem.

    How do I get this to analyze?

    Thank you

    Hello AsusMan,

    Welcome to the HP Forums!

    I understand that you are unable to scan a document using the Deskjet 2540. I will do my best to help you! What is your operating system on your computer? Windowsor Mac?

    I recommend the continuation of this entire HP document on an error occurred while scanning "Message appears when scanning on the computer via a USB connection in Windows. "

    I know that you are able to scan a document using a Wi - Fi connection, but you want to ensure that the software is correct when a USB cable is connected. At the end of this document, it does not specify to uninstall/reinstall the software. (Only if you reach the end of this document.)

    Please post your results, I'll be looking forward to hear from you.

  • DeskJet 2540: Deskjet 2540 print and Scan works on Windows 10

    I have installled, uninstalled and reinstalled the software half a dozen times now, on my Windows 10 machine, but I still don't have any interface to scan documents.

    The installation process has shown a success install and I was able to recognize and connect to the printer. In my Start menu, the new option 'Scan & Print' is there, as shown in the screenshot (click on the screenshot to the size of the full image).

    But when I click on the option, instead of the usual analysis and the dialog box print, I am faced with a new printer 'Connect' and 'Add more software' options (see screenshot below).

    How can I get to the good old scan dialog box?

    Among others, I used to have an option here to scan directly to PDF. This option is not accessible from anywhere on the machine and is something I desperately need to back.

    Has it been removed from version 10 of Windows? I ran a search for "Scan" computer, but the only options I get are native Windows analysis (which works very well for the individual photos) and this dialog box. Nothing that would allow me to scan a document of several pages in PDF format

    with this tool, I could connect to a deskjet 2540 in a wireless network and make a pdf of several pages of analysis.

  • 7610 large scan, scanner head gets stuck

    When you scan a bulky, the scanner seems stuck right ene come and go.   If I open the lid, it stops.  I scan only the scan with cover open otherwise it get stuck.   Using Mac os 10.9 with HP driver.   Using the inmage capture software.  I think that it is question of hareware.  Any ideas?

    Hello rgjenksand welcome to the Forums of HP.

    I see that your scanner lamp hangs on the right unless the lid is open.  I suggest you perform a power reset.  Unplug the power cord from the printer and the power outlet, then wait 60 seconds. After 60 seconds, plug back in the printer. Make sure that you connect the printer directly to a wall outlet. Make sure to bypass any surge protector or power bar.

    I also suggest updating the firmware in the printer.  You can download the update using this link: HP Officejet Firmware.

    If this does not work for you, then it is more than likely a problem of hardwaqre, and your best course of action would be to contact HP directly.   You can use this Web site for information about how to contact HP properly, based on your region: contact HP worldwide.

  • No communication with scanner

    Just installed Mavericks 10.9 on MiniMac and scanner cannot communicate with the computer. Using an Officejet 6500 connected via USB. There is also no scanner in an Image Capture Application. All solutions?

    If you are using Snow Leopard, Lion or Mountain Lion and have HP software for Snow Leopard before (either from a CD that is not marked as compatible with 10.6-10,9 or you recently upgraded to Snow Leopard, Lion or Mountain Lion and had the software HP on your Mac before you upgrade - even if you made a standard uninstall of the old software or installed new software on top of it) You must uninstall the software by using the "scrubber":

    Go to Applications/Hewlett Packard / click Uninstall HP
    Click on continue
    Highlight your device in the left pane
    Press on and press and hold Ctrl + Alt + Cmd keys on the keyboard at the same time as you click on uninstall, it IS the Option of the scrubber, no button is labeled "washer".
    There will be a pop up that asks if you are sure you want to uninstall all hp software. (At this point, if you continue, all HP printers you have installed will need to be reinstalled)
    Click on continue and let it finish

    Download and install this: http://support.apple.com/kb/DL907

    Restart your Mac.

    Now reset the printing system:

    -Sys Prefs, Print & Fax
    -Right (control) click inside the box that lists your printers and select Reset Printing System.
    WARNING - This will remove ALL your printers!
    -Select the sign + to add again. Search for the printer, select it, and wait until the button 'Add' becomes available. Until it clicks.

  • "Reserved for Scan PC scanner"

    When I try to scan with my 3055 I get the message "scanning error. Unable to connect' "Reserved for the PC scan Scanner."

    There is no another scan attempt.  I can do a preview and see the picture very well.  But when I type analysis this problem occurs.

    I've seen many references to similar problems, but no solution.  Can anyone help?

  • Problems scanning with HP Photosmart 7520 and HP Deskjet 2450

    I could have sworn I posted this earlier, but I can't. I have problems with scanning for computer with my 7520 and 2540. The scan of the computer does not work.  On the 7520 when I try to scan a document to your computer in PDF format, it works. When I scan in JPG format, I get errors. "The"Move Finder items"action has encountered an error" and "no connection" appears." I have two printers installed wireless and wired hard. Cable installation the "Scan to Computer" is enabled but does not work. On the wireless (Hello), it says "Scan to computer" is not enabled. Scan the small icon on the bottom of my screen does not have an option of the printer to use. This shows just the 7520. The only way I can scan almost anything with the 2540 is through the Web site. The strange thing is. I have a laptop wireless hung in the living room and I have no problem analysis to the computer with both printers. Just my office's problems. How can I fix?

    A power failure may cause problems. We had a power outage yesterday in my area.

    Hi @Helen

    I'm glad to hear that they are working together again.

    It seems that you may have an option "detect the separate components' selected somewhere in the settings.

    Let's take a peek into the HP Scan for this feature, and if find you it clear.

    I just checked a Mac I have access to and I found a setting that would do the same thing that "detect the separate elements", it is called point limits and is located in the culture section. If your article harvest limits element selected, change it to zero.

    The parameter you want may depend on the Mac version you are running. If you can't find the options I identified above, let me know what version of mac you have, I'll do some additional research to find the solution!

    Since we have not fixed the first problem, think about scoring the post that solved the problem like "Accept as Solution" if others in the community can find the solution easily. Thank you.

    I can't wait to hear back on your part.

  • Can't scan on HP 1410

    Hi there, the last days of couple that my HP PSC 1410 all-in-one has decided he will not scan.  Still, it prints and copies well.  So I tried the tutorial on the site of hp and got to page 5 where it gives me a link to the HP scan diagnostic utility.

    Anyone know what is happening?  I am running Windows Media Player aka Windows XP.  When I do open HP Director, and click Scan, it gives an error "year error occurred while communicating with scanner.

    The USB is plugged in correctly, it always prints and copy so what can I do to make it scan the image?

    Take it on me, I have tried to fix this for hours and cannot find a solution.

    If the Erny link does not work, try this one.  Sometimes, the firewall settings prevent using the ftp links.

    Kind regards

  • Scan-AiO Printer to pdf on mobile

    Hello

    After spending too much time on this, I decided to post a question. I use AiO Remote printer app on iphone, paired and works perfectly with printer Wifi Deskjet 2540.

    Scan several documents and then it becomes more difficult!

    I want to save my already scanned multiple pages to a pdf file, but there is no option to do so. On adroid devices workes perfectly. Why is there no option to save a scan of multiple page in a single pdf on iphone?

    When I save the documents they turn upward in one multiple separate jpg files folder.

    Following problem. I can't select and send more than one file (in this case the annoying jpg files) at a time. The only "select" option is used to delete them or not.

    Am I oversee things or using your app on iOS has many gaps.

    Thank you

    Hello

    you were not able to scan multiple pages as uour scan type is set to Image.

    Changes to this document will allow scanning of multiple pages.

    Click the Scan option, then set Input document Type and confirm.

    Now click on the page icon Add (the right) to analyze the nect page until you are finished.

    It will be saved as a PDF.

    You cannot change existing files using the app, it's a scanning application and not a picture editing software.

  • scanning multiple pages

    I just bought a series of all-in-one HP Deskjet 2540 mainly for scanning.  I can digitize unique pages, but can't figure out out to scan multiple pages into a single set.  All I see is 'search of multipage documents as single or multiple files come back and go to the file tab in the advanced settings'.  What do I do from there?

    Thank you very much.  In fact, I think that I just thought of it.  When you hover over the more it says check «back»  However, in another place, he says 'return' is just for when you are not satisfied with the scan and must be clicked after xing on.

  • Improved HP software and now get the error scanning

    IMac bought 3 months ago (Mountain Lion 10.8.2).  Operations to scan and print on my Officejet Pro 8600 (N911A) worked well.  Also knitted for laptop with Windows XP.  I had never installed any software for this printer on either computer graphics since it was recognized and worked on both computers.

    Today, I downloaded what I thought, it was the last version of the software for the officejet on the iMac.  Now, I get an error message when I try to scan: "Scanner reported an error an error occurred when communicating with the scanner."

    The printer works from the iMac printing and scanning for the Windows computer.  I'm NOT using the wireless options.  Computers and the printer are connected through the router.

    I'm confused about the version of my scanning software as indicated in my computer I have version 3.6.0 and I think there's more recent versions for the iMac.  I followed the instructions to get the latest version.

    Shortly after posting the above concerns, iMac has announced updates that were available for my computer.  One of them includes an HP upgrade.  I had downloaded them and installed.

    Now my scanner works from the iMac and I also OCR which is what I was looking for when I did the initial upgrade earlier in the day.

    Interesting that the scanner still shows version 3.6.0.  That's fine with me.

    Problem solved.

  • D1370 "Scan type not the Remote Scan value... "Why this error when connected via USB

    Printer D1370 MF w / usb on win7 x 64 machine connection.

    I understand that when networked, I owe to the printer and manually press , then then before you scan using the software MF Toolbox on my PC and then must go to the printer once the scan is complete and cancel this setting manually before I can print or use other functions. What is total pain BTW...

    However, I also have a MF6530 and can scan directly from MF Toolbox without manually change the setting of the printer when connected via USB.

    So, I would like to connect one of my PC via USB for scanning to eliminate the requirement to manually configure the printer for the mode. But, when I do this I always get the error "type of analysis is not defined for [Remote scanner] on the device" even though I am connected via usb.

    1. I do something wrong when I try to scan via a usb connection that causes the error "remote scanner?

    2. that this has something to do with D1370 being a network printer. My MF6530 isn't a network printer.

    3 is there a manual for the software MF Toolbox? The manual on the installation disc is for 'Send email' and 'Store to Shared Folder. The manuals provided in the box do not address MF Toolbox. There must be a detailed operating manual provided by Canon for this program?

    4. What is the error Code 162,0,0?

    5. where is the complete list of the error codes for MF Toolbox.

    6 help!

    Hi monza.

    I know that this issue is frustrating and I'll be happy to help you.

    The new imageCLASS machines are designed so that you can select an option to scan the machine.  There is no way to set a default scan on this computer option.  You will need to select [Remote scanner] or [computer].  This is to ensure that your device correctly handles the scan project.  For this reason, the ability to program a specific mode is not available.

    Although an extra step to make, an advantage to choose the mode desired for a respective scanning can ensure that poor communication of scanner does not occur if it was programmed to a different mode.

    The 162,0,0, the error indicates the Toolbox does not detect the scanner mode "Remote Scanner.  Scanning is not supported with a connection on the USB hub, as the hubs can cause communication problems, trying to transmit data to the computer.  We recommend a direct connect between the printer and the computer.  Once you have connected the printer directly, perform the following steps and check if you receive the same error 162,0,0:

    1. Check that the MF Toolbox is closed on the computer and press the [SCAN] button on the printer.
    2. Select [Remote scanner], then press [OK].  The display reads, "remote scanner. Waiting in line... ».
    3. On the computer, open the MF Toolbox and select [PDF].
    4. Click the [START] button green on the window [PDF].  The machine begins to deal with the scan.

    Then I recommend to download and install the e-manual for the device to your computer.  It gives very detailed instructions on each of the functions of the machine.  The e-manual should be included in the manual on CD-ROM supplied with the machine.  If you are unable to access it from there, please click the link below to download the electronic Handbook:
