  • Deskjet 2540 all in one printer - does the scanning work with Mac OS Yosemite 10.10.1 ?

    I was trying to scan a document using this new printer and my Mac OS Yosemite 10.10.1 and I cannot even find the page that allows me to scan since now it is all through the computer.  Is this printer compatible with this operating system? and if so, what can I do to see the page where the file actually shows up to scan?
    thanks,
    Natali

  • Re: Deskjet 2540 All-In-One

    I have a gateway notebook with no cd/dvd capabilites.  I tried to download the drivers from your hp.com/ePrint/DJ2540 but seem to get nowhere.  It appears to download and gets to #2 then stopsl - and I can't print.  Where do I access the drivers for this priter?

    Hello there lcastor050, Welcome to the forums.
    I understand you are unable to download the drivers for your Deskjet 2540 as the installation stalls on you. I am going to post you a link to the drivers and software download page. You will need to select your operating system and then download the driver from there.

    If this doesn't work, please respond to me with your operating system and I will look into this some more for you.

  • Connecting hp deskjet 2540 all in one

    How do I connect my go desckjet 2540 all in one to my iPad and iphone?

    Hi @Krissy13 
    Welcome to the HP Forums. I would be happy to help you get your Deskjet 2540 onto your network. I use this method for iPads, iPhones and other devices that do not have software.
    Restore the network defaults on the printer by pushing the wireless button, going to settings, and then restore defaults. The wireless button should then start flashing, this means it is now in autowireless mode.
    Connect your iPad to the network that the printer is broadcasting. It is usually HP-setup-2540 and then part of the MAC address (printers hardware address). The wireless light will still be flashing on the printer at this point, this is normal since this is not an actual adhoc connection.
    Open an internet browser and load up the Embedded Web Server (EWS) by entering the IP address into the address bar. The default IP for autowireless is 192.168.223.1.
    Go to the network tab along the top of the EWS.
    Click on Wireless Setup Wizard along the left hand side to begin configuring the printer.
    Once the printer is on the network, you can put your computer back on your own network and print again.
    If for any reason this does not work, please let me know what operating system , and version you have? Mac or Windows?
    If this does resolve the issue, please let me know by marking this post as "Accept as Solution". Thanks.

  • Deskjet 3520e all in one printer network problems

    Hi All.
    I have a brain teaser for the technical types out there hoping someone can shed some light on a weird sort of problem.
    History: All has been fine with my g6 Pavillion latop 64bit W8 and 3520e all in one printer and working as always very well.
    Oct 16th 2014 My broadband service went down and after many communictions with ISP eventualy received (Nov 4th) and installed a new "super hub modem".
    OK so far, Managed to connect laptop via wireless router and connect to internet etc., however . . . I cannot get my printer to network as before, I can use it via USB port but if I try to network it, The Cyan ink cartridge reports as being broken or damaged even though 3/4 full and will not allow printing, but when connect via USB port the Cyan ink cartridge registers normal and will print as expected.
    Has anyone else come across this problem?
    If I go down the route of uninstalling and reinstallin the Printer software is there a set order in which to do so?
    In the list of programs these four are shown. . 
    HP Deskjet 3520 series Basic Device Software
    HP Deskjet 3520 series Help
    HP Deskjet 3520 series Product Improvement Study
    HP Deskjet 3520 series Setup Guide.
    I would like very much to get back to network printing if at all possible.
    The router IP address is 192.168.1.3
    The printer IP address is 192.168.0.1
    I have been led to believe that as the addresses are so close this shouldnt be the cause.
    I must add that in the past I have had occasional printer software problems which I was unable to resolve without help from the technical centre and I would prefer not to restart the installation if at all possible.
    Your comments would be appreciated.
    Thanks in advance.
    Un1corn.

    Hi @Un1corn 
    What exactly happens when you try to convert from USB to Wireless and configure the printer to the Virgin Media Super Hub? Do you get an error message of some sort?
    Maybe there is a firewall on the Super Hub. Do you have the model number for this device? I can look up some information to see what could be casing the issue.
    In the meantime, running the Print and Scan Doctor might help. The HP Print and Scan Doctor is a free utility (tool) that helps to quickly resolve common printing, scanning and connectivity issues including but not limited to:
    Connectivity:
    USB: Verifies that the USB connection from your computer to the HP product is working correctly.
    Network: Verifies that the network connection between your computer and your network is working correctly.
    Device Status Test: Checks for device errors such as out of paper, paper jams, carriage stalls, and paper feed issues, and then provides instructions for fixing the error.
    Driver Check: Checks for missing or corrupt driver files.
    Device Manager: Checks for problems in Device Manager that would prevent printing.
    Device Online: Checks if the product has been paused or set to offline, and then sets the status back to online if necessary.
    Print Queue: Checks for and clears pending print jobs in the print queue (a log of print jobs waiting to print).
    Port Match: Checks the port settings for the HP product.
    Device Conflicts: Checks for conflicts with other drivers, such as other printer brands.
    Ink Issues: Checks the cartridges and ink levels for issues that affect print quality.
    Print Settings: Checks and adjusts the print quality settings.
    Test Print: Prints a test page for print quality evaluation, and provides options for cleaning and aligning the printhead if necessary.
    Scan Tests: Checks the scan mechanism, drivers, and registry entries.

    If that does not resolve the issue, post back and let me know if there are any symbols other than green check marks and what they are next to of course. The wrench is not always easy to spot as the wrench and the check mart are in the green circle.
    If you see only green check marks (), the tool did not find any problems.
    If you see green wrenches (), the utility identified an issue and corrected it automatically.
    If you see yellow exclamation points (), the test failed and required user action, but the step was skipped.
    If you see a red X (), follow the on-screen instructions to resolve the issue.
    I look forward to hearing back from you.

  • Old MSI all-in-one wireless connectivity problem

    Hi folks,
    Hope someone can help - if only by sending me somewhere else!
    I have a reasonably old MSI all-in-one model MS-6633 (NetON AP 1900) which I bought new perhaps 6 or 7 years ago.
    I'm running it wirelessly, connected via a TP-Link Powerline Ethernet Adaptor.  My main PC is wired to a TalkTalk modem.
    For some reason it's recently been disconnecting itself from the internet, although, by going to 'connect to' I can usually fairly quickly regain the internet connection.
    I've spoken to TalkTalk and their tech guy ran 20 minutes of tests - at the end of which he said that there was nothing wrong with my internet connection or any other equipment leading to my PC......so the problem must be in the MSI unit.
    Mind you, I don't entirely trust him - would he tell me if I was getting brief disconnections caused by a fault at their end?
    He gave me the MSI number (0870 8200 009) - which always comes up with a "we're busy" automated answer - and I don't know what else to do.
    Can anyone help; tell me what I need to do, or redirect me to somewhere useful.
    Thank you

    Hi there - glad someone cares!!!
    Yep - definitely in the UK - whether I like it or not!
    Right - O/S is Windows XP Home edition
    Automated updates are always turned on....
    Connection to the phone line is by router
    I considered removing and re-installing the drivers, but thought I'd ask around first.....
    Actually, yesterday I did a clean-up which hadn't been done for ages.
    The computer concerned is my spare/back-up, which my wife uses at present and I do tend to forget to do any housekeeping on it though, but  ever since I worked it over, (cookies, temp files, etc removed) there's been no problem with the internet connection.
    I'm not taking the kudos - I just thought I'd do it and just perhaps, it's solved the problem.
    However, if anyone knows of a better way to ensure that the computer remains connected, I'd love to hear from you.

  • HP Deskjet 2540 All-in-One Printer

    Hello. I was wondering if anyone has used this printer on their Macbook OSX 10.9.1.?
    Or any other suggestions for compatible printers. I was bummed when I realized my Kodak wasn't compatible and now have to get another printer.
    My range of price for a printer would not be more than $80 so I'm hoping you guys can help me find a printer good enough. All I need it to do is to print documents and scan. Nothing more, nothing less.
    Pleae help me, thank you!

  • HP Deskjet 3050 All-in-One Printer connected to pc, can't connect to laptop

    I've been using this printer via USB for a while now and finally set it up wireless. It works fine on my pc (Windows 7), but I can't see it with my wife's laptop (Lenovo ThinkPad also Windows 7). I can look up the IP address in a browser on my pc and actually get into the printer, but when I do the same on the Thinkpad it just returns with a google search for the UP address.

    I can also access the printer via IP on my Kindle HD, but not the laptop.

  • HP Deskjet 2540 All-in-One

    I accidentallly changed my permissions when setting up the wireless aspect of my printer and in the "Security" tab within properties i changed the tickboxes for "Everyone" to deny for all three options and i cannot access the properties or software to change this. I wish to know how gain access back into the properties while the printer is wireless or to be able to completely reset the printer to factory settings.
    Thank you.

    Hi mari136,
    I had searched high and low, there is evidently no full reset to restore the printer to a factory setting; however, I found a different reset we can try. Please complete the steps below.
        Press the Wireless button and the Cancel button from the printer control panel at the same time
        Hold them for 5 seconds.
        If the wireless button is no longer on, press the Wireless button from the printer control panel to turn it back on.
        Leave the printer on, and unplug the power cable for 1 minute, then plug the power back in.
    Now you can proceed with the wireless setup again. Please let me know if this helps.

    I see that you are having an issue when attempting to install the printer on to your computer and then printing any thing other than a test page.
    Please make sure that you have disabled any Windows Firewalls and any Anti Virus protection you may have running and then attempt to reinstall the software and drivers again.
