All-in-one Deskjet 2540: reset password WiFi live with security enabled

Good then everything was going well and everything until I one day decided to enable security of the printer and change direct wifi password. It was fine, because I instatly reconnected with the new password and never had to kick it manually again. then recently I accidentally forgot the wifi network and was invited for the password when you try to connect again. I don't remember. I tried everything:

1. I have maintained the direct wireless button for 3 seconds until what it printed on the instruction sheet but no password was on it because of the security settings. To change it, I need access to SAP, which I can't because I can't connect to the network.

2. I tried to reset the default network printer by pressing the wireless button and a button cancel for 5 seconds, it went through the motions and at the end of this, I tried step 1 again, still without password.

3. I even printed the Network Configuration Page by pressing the black copy button and wireless at the same time hoping to find it somewhere a password... nothing.

I'm confused and I need it solved very quickly. any help is appreciated, thanks in advance.

Unfortunately no password yet. I have it connected to the router home as a last resort. Well, your security is really good, but I must add, factory reset should be an option in some way, it's unbearable.

Then I finally found the solution, I downloaded the desktop software, because I lost the CD. Connected the printer to the home network, after a couple of tries, launched the desktop software and clicked on the EWS option. Phew! Finally, I'm here and safe to say, I will never allow new security (not something you want to your customers say huh?) Can you blame me?

  • All-in-one Deskjet 2540: Brand New Deskjet 2540 - "cartridge is Incompatible - black ink cartridge.

    I just got a new HP Deskjet 2540 all-in-one yesterday, ordered from amazon.de, went through the installation of software on my 2015 Macbook Pro running OSX Yosemite, deleted the band contained in 301 ink cartridges provided, placed them in the printer (tricolor on the left, in black on the right) without touching the electrical contacts or the ink nozzles and tried and align the ink cartridges.

    I met an error message:

    'Incompatible ink cartridge.

    Black [K]

    The cartridge listed above is not intended for use in this printer as it is currently configured.

    Please see using printer. "

    Strange, but no matter, the bad seats maybe. I opened the drawer, removed black and reinstalled. Same error message. Well, I ordered an extra authentic HP 301 XL knowing I would run on Finally, maybe my ink cartridge provided was bad. I removed the 301 XL tape and installed. This time, no message error, but as soon as I went to print an alignment page, I received the same error. I went back between cartridges and sometimes I get the printer to accept it, but any attempt to use the printer caused an error message.

    So I went on this forum, found a few tips on how to solve the problem. I tried the resets seats and the relocation and hard. Same error message. I went to clean the contacts, using a cotton swab, filter coffee and bottled water Jig only contacts of eletrical on two ink cartridges (normal and XL) and contacts of printers. I let them dry for 10 minutes and reinstall. Same error message, no progress.

    I'm at a loss for what to do that this is a new printer and I say to myself that I would not have this much trouble. If I could get advice on what to do and more: seats/resettlement, cleaning the contacts, hard reset, it would be appreciated.

    HI bchowseph,

    I found some information about the printer product Specifications.  It does not list the cartridge 301 for Western Europe.  The 61 is for North America.  I think I made the assumption that you were in the United States (my bad!)

    http://support.HP.com/us-en/product/HP-DeskJet-2540-all-in-one-printer-series/5295960/model/5295961/document/c03811750/

    I greatly apologize for the confusion!

    Yet, the printer should accept the cartridges you had - so I think I can get a replacement printer is the right course of action.

    The ink cartridges should be OK for a few days in an airtight container.  You may need to run a routine cleaning cartridge if you see necessary ink missing once you have installed.

    If you need to return the standard procedure is to call HP customer care.

    I hope that everything works with the replacement printer.  I also hope it is resolved quickly!

  • All-in-one Deskjet 2540: copy on Deckjet 2540 darkness setting

    How set you the dark copies on this printer.

    Hi @WJF1,

    Welcome to the HP Support forums.

    I understand that you are willing to adjust the darkness of copy on the printer all-in-one HP Deskjet 2540. I would like to help with that.

    The all-in-one printer HP Deskjet 2540 doesn't have a menu of copy that you can access to adjust the darkness of the copy. You can only set the number of copies. All documents are copied to print normal quality mode. You cannot change the quality of the printing mode when copying.

    You could, as a work-around, scanning the document or image to your computer and then use a third-party software, like Photoshop to darken the document or image. Here is a document that can help with scanning if necessary - using full function software scanning (Windows 8) HP.

    Please let me know if that solves the problem, or if you need assistance.

  • All-in-one Deskjet 2540 fails to connect wireless

    This printer worked fine without thread until I installed a new (AT & T U-Verse) Internet connection.  Previously, I had a combination router/DSL that had wireless 2 sources (hi and lo Band).  The printer connected to a wireless network with the SSID of "Rooter" (stupid name, but what the heck).

    When the modem/router has been replaced by the unit of AT & T, I lost a wireless sender (Rooter) so I tried to change the printer another point of wireless access on my local network named "FBI_Van" (another stupid name).  To do this, I used my cell phone which, at the time, was very well connected to FBI_Van.  I loaded the drivers from the printer to the laptop, connected the USB cable and began to install the printer for the new wireless connection.

    Efforts to do this have failed.  In the window "Select one of the available wireless networks" (after using the link "Convert a USB port connected wireless"), I could see my access point 'FBI_Van' very well.  By clicking on the button "use this connection", asked me to enter password WPA_PSK expression, I did.  It's the same EXACT sentence I used to connect wireless laptop.  The green progress bar went to halfway and then I got the error:

    "Cannot locate the SSID that you entered, try again".  I won't be an SSID, I entered a password that the requested software.

    First of all, I was not one who entered the SSID - this is the software that "judge" and I just clicked it.  Second, the password was perfect without error letter.

    Whne I run the wireless network Test results, using the printer itself (button wireless & B & W Print) he told me that the printer has been tirelessly "Rooter" looking for (and not finding).  The blue wireless LED blinking and the "signal strength" LCD is forced.

    So, after this long explanation of events, what can I do to make this printer to accept a new SSID access?

    Is there a way to reset the printer to "factory delivered" settings so I can start over?

    Bill

    To answer my own question.  Is there a way to reset the part of the printer wireless.  It is NOT mentioned in the manual, but here's how do:

    When the printer is on, stop the LED flashing wireless by turning off the wireless.

    Hold the button cancel (the big red 'X') and the wireless button at the same time.

    Wait about 10 seconds until the power light flashes once.

    Go to the computer that you have installed the printer software on and go down the menu to "Printer Setup and software" and click on that

    Press the radio for wireless configuration MANUAL (do not push the button 'connect to the router')

    Follow the screens to select the wireless network you want, click Next

    The password for the connection of input and let the software connect the printer to the network.

    It MUST work, if not, repeat the operation (I got two times)

  • DeskJet 2540 all-in-one: Deskjet 2540 only prints PDf files

    I got a 2540 for my grandfather a few weeks ago. When I put to him that it worked fine. Now, however it will only print opend with Adobe pdf files and I have no idea why.

    Any other print command will result in a blank page or a page with a few veins of black or color. It will not display even a test page.

    This could very easily be a problem with the machine of my grandfather because it is very old and running Windows XP 32-bit. I also have no way to connect his machine on the internet before taking him home and update mine and I prefer not to do so.

    I tried to download the drivers on an external device and then editing them, but that has done nothing to solve this problem.

    Any ideas?

    Thanks for the replies

    It is black ink. It must have been damaged as when I replaced it with a new one that he started printing very well. The reason why that worked the pdf was because it was all in color and like the fool that I am, I have not noticed.

    Thanks for the quick response.

  • All-in-one Deskjet 2540 print not web pages

    I just installed this printer in wireless mode. It prints well applications like excel, word, acrobat, etc, but will not print pages from google, such as google maps and others.

    Hi Len46,

    I would recommend a print with a different internet browser, such as Internet Explorer or Mozilla Firefox, to see if there is any difference in printing output.

    Thank you

  • HP Deskjet all-in - One 1051 registers as an all-in-one Deskjet 1050

    Recently bought a HP all-in-one Deskjet 1051.  After you have installed on the computer, he enrolled as a series of J410 Deskjet 1050 all-in-One.  I was wondering why.

    The numeric designation may vary according to the regional location or the retailer where the product was purchased. It can also link in how the product as the default value of different media formats, for example in North America with paper letter against Europe with A4 size. What it boils down to is that your printer is a Deskjet 1050 printer specific specialized series for a retailer or the country.

  • All-in-one Deskjet 3632: Deskjet 3632 black ink not working not

    Hello

    I bought a HP all-in-one Deskjet 3632 and have set up on my laptop and phone. I scan a document was nice and feel it was ok, but the documents will not print using black ink. The first impression is rather a gray, and it seems that the color ink is the only one used. When you print word documents, none of the black ink is printing and only a small amount printed on the first page of test, where none of the letters are readable at all. The cartridges are new and in the same area as the printer. I did the fixes suggested without result, bar to buy a new cartridge which I hesitate to do what the budget is tight. Is there a fix that can be made, or will I have to resort to buying a new cartridge?

    Greetings @JamesMontgomery,

    Thank you access the Forums from HP Support for extra support! I see that you have problems printing in black. I will do my best to help you with this problem.

    I wasn't sure of what you have already tried. I would say the contacts of the cartridge cleaning manually, if you have not already: ink cartridge errors. Do not take into account the title.

  • All-in-one Deskjet 4535: Deskjet 4535 AIO - Scanner function not supported in Linux Mint 17.3?

    I just bought the all-in-one Deskjet 4535. As I could not set up in Linux Mint 17.3 using hplip 3.15.2 and hplip-gui (it wouldn't appear in the peripheral installation dialog box), I used the utility printers (system-config-printer) and configured through CUTS. Even then, I was forced to use the driver 4510, as a driver of 4530 series does not seem to exist.
    After having done that, I can print it, but I can't use the "Simple Scan" scanner or any other utility to scan.
    I also tried to detect the network with xsane Analyzer, but it would not detect it.

    The only way to use the scanner is via the web interface, the all-in-one offers fortunately.

    Is there something else to try? The 4535 is supported under Linux or am I out of luck?

    Well, I went to hplip.sourceforge.net and I should have started with it in the first place. I solved the "problem" in downloading and installing the latest version of hplip that supports the 4535 entirely. The repo of Linux Mint has an outdated version of hplip and 4535 needs at least version 3.5.11 to work properly. Use the latest version fixed it immediately.

  • All-in-one Deskjet F3335 allows to print "black only" on the profile of a user, no other

    Hello

    I have an annoying problem with my all-in-one Deskjet F3335.  I print a lot of documents on my printer.  Rarely do I need to print anything in color.

    Since the acquisition of a computer running Windows 7 (x 64), I was not able to print in "grayscale: black cartridge only" on my profile; the only option is 'high quality '. (see image below)  I thought it was a systemic problem until printining something user profile on my husband.  His profile will allow for me to select "black cartridge only."

    I tried to uninstall and reinstall the software and updates. This did not help.

    Hoping someone out there might have a suggestion for me on how to solve this problem (and stop wasting my color ink)! Thank you

    As I understand it, you can change the printer to print in only black and white on a profile, but not on the other on the same computer. Is this correct?

    This type of question usually depends on the permissions available on each profile. I would hazard a guess that your husband is a Director or that there privleges more than your own profile. I check to make sure that your account is set up as an administrator first.

    Secondly, I would also check the 'Advanced' tab, that sometimes you can change the settings for printing color black and white or grayscale.

    Let me know!

  • All-in-one DeskJet 4625 and printing with Mac OS 10.9 Maverick

    I just installed Maverick - Mac OS 10.9 - and print is no longer a device all-in-one DeskJet 4625.  The computer and the device are communicate since I can see the ink levels, scanner and other functions, but it will not be printed.  I know that there is no problem with the printer, since I can print to it from another computer that has installed Mac OS 10.8.  Apparently, there is a need for an update of the printer driver.  Apple support is not an updated driver.  So, my question is hp will provide an updated driver?  And when?

    Hello

    Apple provide a updated driver.

    First restart your Mac, then click on the Apple icon and select software update, do not forget to install any available HP or Apple updates.

    If you can't print, try installing the package from the link below and check if this is useful, although it does not list the Mavericks, it should work on the operating system as well:

  • printer Deskjet 2540: lost password

    Hi am new Android phone and Tablet also lost all the information (I forgot to save) reinstalled HP ePrint. AL in one company to distance and ePrint

    Which none are for letting me print saying no printer found internet or not no password

    Unfortunately I don't remember the password any help would be appreciated as not good with technology

    Thank you

    Sharon

    You might want to try to set your printer to the factory settings that should erase the passwords can be added when you configure applications. I'll look in a specific way to do for your printer, but in the meantime try what works for my all in one printer scanner.
    Turn on the printer.
    turn it off by unplugging the power adapter, wait a minute.
    If it has a keyboard, press and hold the # and 3 buttons while plugging the adapter back in. Keep and hold keys until the printer reboots.

    See if you can print from your Tablet after the reset.
    Sometimes simply unplug the printer for a few minutes will reset things.

  • DeskJet F4280 all-in-one: Deskjet F4280 print white

    Hello

    I just inherited a HP Deskjet F4280, printer all in one and put in place.  It auto downloaded the correct driver from Apple and added the printer in system preferences / print and fax.  I use OS 10.10 on a mini mac computer.

    I tried an alignment page and it prints blank page.  Goes through the motions as if it's really the impression, but the page is empty!  Tried a regular document via overview and MS Word, same result... blank page.

    I checked and the utility said all the cartridges are fine and have enough ink.

    I deleted the printer and readded twice and reset once the CUPS.  Same result.

    Any other ideas?

    Any help is greatly appreciated.
