HP Officejet Pro L7780 ink cartridges leaking

The printer says I need to replace cartridges even though I already did. I discovered the ink is running throughout the printer, over the mother board and out the power supply connection. Has any one else had this problem?

  • HP Officejet Pro X476dw ink cartridge failure

    I have a new HP Officejet Pro X476dw . It gives me Ink Failure for the four cartridges when I shut it down and turn it on the next day it starts to print but after a while it gives the same message . and so on I check the cartridge when it is working , it is already full of ink .  
    it is the ink which come with the printer in the shop they told me it shoud print at least 2000 pages using those inks . 

    @ SMOKEY DOG  -  I will need a little more information in order to help out. Do you have the same printer as the one listed in the title? Are you using genuine non refilled ink cartridges is the device?  Do you have the printer plugged directly into a wall outlet to ensure that it is getting the proper amount of power? If the printer is not getting enough power, that can cause the printer to produce erroneous error messages.

  • HP officejet Pro L7580 ink cartridge problem

    I have read some other posts from people that seem to be having this same problem, but have not seen any answers on how to fix it.  I have recently bought a new ink cartridge that contains both the black and yellow ink.  When I put the new cartridge in the message center displays that the ink is still empty.  This is a printer that i use at work and it is becoming very frustrating, especially when I am trying to print and it won't let me because it thinks the ink is empty. Any help would be appreciated!

    I don't think there are any ink cartriges for this printer that contain yellow and black ink.  This printer has 4 "ink cartriges" for black, magenta, yellow and cyan.  It also has two replacable "print heads" which are only responsible for depositing the ink on the paper.  These replacable print heads each do two colors and black/yellow is one of them so it sounds like you probably bought a replacement head instead of replacement ink.  You need to buy this type of cartrige:
    HP 88 (C9388A is the yellow version)
    Hope this helps

  • HP Officejet Pro L7780 All-in-One Will Not Print Blue Ink - It Prints Pink Instead

    HP Officejet Pro L7780 All-in-One -
    Issue:
    Blue ink will not print (It prints the color pink instead.).
    Actions taken:
    1.  Cleaned ink heads.
    2.  Replaced ink cartrige.
    3.  Reinstalled software.
    Sugestions by HP customer service:
    Purchase a new printer: Because the issue is software related - not reading the blue ink cartrige.
    Any suggestions or advice would be very much appreciated.
    Thank you for your time!
    Thank you.
    Sincerely,
    Ryan

    The cyan portion of the printhead may be clogged.  I would suggest running the diagnostics shown here.  If three levels of cleaning of the printheads does not resolve the issue you may need a new printhead.

  • On a HP Officejet Pro L7780 All-in-One printer, is there a toner and where is it?

    On a HP Officejet Pro L7780 All-in-One printer, is there a toner and where is it located? I've looked in Products and Supplies and don't see it but my printer is saying that it's low or empty.

    By now, you have probably discovered that the L7780 does not use a toner but cartridges.  It actually uses 4 HP 88's.  They are black, magenta, yellow and cyan.  Usually, black is the first to be replaced.  They can be found at Staples, Office Depot and Best Buy.

  • OfficeJet Pro L7780 - Have to Restart Print Spooler every job I print (Windows 7 32-bit)

    I have an OfficeJet Pro L7780 that shows as offline in Devices and Printers constantly.  I discovered if I queue up print jobs to it and then restart the print spooler all of the jobs will come out perfectly then the printer will instantly go offline.   Here is what I've done for troubleshooting already:
    Upgrade to newest firmware (R2011NxNxeN0)
    Factory Reset by hold # and 3 at boot
    Changed Ink and Print Heads
    Installed newest 14.0 driver (tried both Basic and IT Pro Driver)
    Rebooted and restarted printer and computer
    Tried all this on a 2nd Windows 7 computer with the same results
    Anyone actually use this printer on Windows 7 32-bit over the wired network port!!?!
    This question was solved.
    View Solution.

    Same printer, same problem, same remediation by restarting Printer Spooler service.  Only difference is OS is Win 7 Ultimate 64-bit.
    FYI- I'm using my L7780 via a wifi connection using WPA2 security and a static IP and network RAW printing to port 9100.  The printer always appears available via network pings but not to the print spooler.  As such, printer is always "grayed out" and disabled but will accept jobs into its queue.
    After endless searching this is what appears to be working as a fix:  Turn off SNMP on printer port.
    Printer Properties -> Ports Tab -> (Select Port) -> Configure Port -> uncheck "SNMP Status Enabled"
    Hopefully this works for others- but I also found mention that others found a fix in toggling other settings such as "Enable bidirection printing" check box.  Who knows what seemingly unrelated software triggers this issue but it began one strange day and drove me crazy.

  • Duplex Printing Problem - Word 2007, Vista and HP Officejet Pro L7780

    I'm having trouble with duplex printing on my new HP Officejet Pro L7780, from Word 2007, running on a brand new Vista system.  I've also had this same problem (repeatable) with two other computers, running XP Professional/Word 2003, XP Home/Word 2003.  All of the service packs have been installed for the operating system, word, and printer. 
    If you print a landscape document, using the auto duplex setting for the HP printer, the margins will print out offset by .25 inches, on the left and rigt margins.  So if your margin is 1 inches on right and left, the margins will print to .75 on one side and 1.25 on the other.  This would be annoying, except that I'm trying to print brochures and books, which requires that the pages print out exactly as set up... "close enough" isn't working for me
    The way I have replicated this problem is as follows:  set up a document in landscape format, using the default margins.  Insert an image on page one, size it so it takes the full margin area.  On the second page, fill it up with text.  Print the document, selecting the printer properties and setting Print on Both Sides=Automatic.   The easiest way see the problem is by holding the document up to the light.  The front and back margins should match and they don't.
    Any help you can provide would be very much appreciated.

    Diana,
    This problem is perhaps much larger than you might have imagined.  We have tried to work with Hewlett Packard for over two years on the duplex printing problems.  In the process, we have expended over 100 hours of effort in troubleshooting the problem which has included updating software, reinstalling software, developing test documents, escalating issues, submitting technical findings, and in purchasing replacements.  Unfortunately, our efforts to interact with Hewlett Packard excalated support have resulted in an aire of apathy, disinterest, incompetence, frustration, redundancy, occasional discourtesy, and an outright lack of professional decorum - something inconceivable of a large, reputable company.
    We have identified several problems with duplex printing.  The duplex printing problems include irregular margin increases (.25 to .50 inch), margin shifts, cut-off text, compressed text, and compressed graphics.  Please note that most of these problems are only evident when printing documents from computer applications to the printer.  If the user simply uses the front printer panel to copy in duplex mode, these problems are not always evident.  This suggests that the printer mechanics are capable of properly duplexing and that the problem lies in the drivers.
    The problem is evident on the HP OfficeJet Pro L7780, Photosmart L7180, Photosmart C6150, Photosmart 3310, and likely on many, many other HP models.  The problem is evident on many computers (HP, IBM, Toshiba, and Dell), is evident in multiple applicatons (Word, Wordperfect, Excel, Peachtree, Notepad, and many more), and is evident on multiple operating systems (Windows XP Home, Windows XP Professional, Windows XP Media Center Edition, and Microsoft Vista).
    We consider ourselves to be extremely polite, patient individuals, but have nearly been driven to outrage by the indignant disregard offered us by HP's escalation support department; a department which should represent the cream-of-the-crop in both service and technical expertise.  Given the ease with which the problem can be duplicated, we expected an extremely quick resolution by HP who, to our knowledge, has never even made the effort to duplicate the problem in-house on our behalf.
    Ironically, HP highly advertises their J.D. Powers rated technical support, yet it appears that they actually have extremely poor published consumer rankings in some of today's mainstream computer magazines.  HP technical support makes no apologies for the fact the user cannot use a major feature of their printers, offers no indication that the problem is even being addressed, and off-loads the responsibility by suggesting that we contact Microsoft (who is to blame for this issue).
    Thank you, Diane, for your message.  We had a hard time imagining that we were the only one experiencing this problem, especially when HP promotes such a representation.  Which also begs the question why HP plays like the problem does not even exist?  I also fail to understand why HP technical support shows so little interest in a problem that is easily duplicated and adversely affects a major feature of the printer which is commonly used by individuals purchasing equipment for its duplex capabilities.
    This is sad because we have been a loyal customer of HP for over twenty-five years.  There was a time when we would have happily endorsed HP's steller products and steller support (provided you could get a problem escalated).  Now, however, they all-too-often appear to offer equipment that fails to support advertised features which is backed up by sub-standard support and extremely expensive ink.  This is an especially sad commentary for users who are buying HP's upper-end printers and computers.
    We desire to know if there are others out there experiencing similar problems?  If you have experienced these problems or would like samples of the problems we have duplicated, please respond.  I think the more information we gather, the better our chance of a successful resolution to a serious problem.
    Thanks Everyone!

  • Can't configure Wireless Connection to HP OfficeJet Pro L7780

    I recently purchased both my iMac 24" 2.8GHz computer with OS x 10.5.2 and HP OfficeJet Pro L7780. I was able to use the HP setup CDs for my Windows laptops and configured them to use the printer in a wireless configuration.
    The iMac is creating the headache (actually I think it's HP causing the headache). When I try to install HP's driver 9.7.1 using their utility, it is unable to detect the L7780 in a wireless configuration. The moment I connect via USB or wired Ethernet, the printer is detected without a problem. My printer is located @ 192.168.1.30, fixed IP address via a NetGear FSW308 switch. My iMac is fixed @ 192.168.1.100 and the gateway is 192.168.1.1
    I spent hours on the phone with HP support and am still in the same spot... HP software won't find the printer when it is wireless. I can configure OS x 10.5.2 to use the internal L7700 series driver and put the IP address in the dialog box. The printer prints without issue using the OS printer drivers, but the other features such as scan and fax will not work without the HP software.
    I can ping the printer and I can connect to the printer's EWS, but the HP software will not find the software.
    Overall config: iMac wireless network connection to switch; Printer also wireless connection to switch.
    So far HP is dumbfounded and all they can say is that I should call Apple because the printer software works fine when I connect the Ethernet or USB cables.
    HELP!
    Thanks,
    Roland

    Thank you for the thought. Yes, although my SSID is public, I have a WEP 128-bit security key. The printer, the iMac and my Windows laptops all connect to the wireless network without issue, as evidenced by my Windows laptops and iMac (if I use the driver included with OS X 10.5.2).
    I can ping the printer from the iMac as well as connect to the printer's web interface, so connectivity exists. It is as if the setup software or the printer are trying to communicate using a port that or service that OS X may be blocking.
    My OS X firewall is configured to accept all connections though... so that shouldn't be the issue unless there is a bug in accepting all connections.
    Thanks,
    Roland

  • HP Officejet Pro L7780 All-in-one not scanning with Yosemite

    I have searched for a workaround or fix to the scanning problem I'm having. I just bought a brand new Macbook Pro Retina and have loaded the latest printer drivers for the HP Officejet Pro L7780. The printer works ok, but I can't get the scanner to work. When I try, it says: "Failed to open a session on the device."
    I'm using the printer over a wifi connection.
    Can anyone help with this, please?!
    Thanks!

  • HP Officejet Pro L7780 - Network Letter Nightmare!

    Hello.
    I'm hopin somebody can help with a problem I am having with my HP Officejet Pro L7780:
    The printer is connected to my wireless network and all is well with this. The problem lies with the network letter that  it assigns itself to on my PC (Windows 7 Ultimate) for the in-built card reader on the printer. It is using the same letter as a virtual cd-rom drive on my PC - and I would like to move the letter the printer uses - and not the cd-rom drive, as I have my PC setup in a way where different types of drives are grouped together. Is there some way (possibly through the Windows registry) that would allow me to change the letter of the network drive (as it seems to automatically assgn one) and keep it using that new letter rather than interfering with the cd-rom drive and denying access to it every time Windows 7 boots?
    Or alternatively disabling the card reader function on the printer as I don't use it?
    Thanks to anybody who can solve this - as it is driving me mad!
    This question was solved.
    View Solution.

    I finally found a solution to this problem that works for me.
    I too have an HP printer that was mapping its memory card slots to a Z: drive every time I booted my Windows 7 computer.
    To change the mapping to another letter to free up the Z: letter, I placed a memory card into one of the printer memory card slots. I then disconnected the Z: drive from the printer mapping (right click the Z: drive in Windows Explorer and choose the Disconnect option).
    I then used the "Map network drive " option on Windows Explorer toolbar to map the printer memory card slot to another drive letter. You have to know the network address (or name) for the printer to do this:   \\[printer network address or name]\memory_card (e.g.: \\192.168.1.108\memory_card). This address goes in the "Folder" textbox of the Map dialog window. Make sure the "Reconnect at logon" option is checked. And make sure you select a new drive letter that won't be needed for anything else later. Then click "Finish."
    After I did this, the printer has continued to use the new drive letter at boot-up instead of Z:, leaving Z: free for other applications.
    I don't think the above works if there is no memory card in one of the printer memory card slot.

  • HP Officejet Pro L7780 All-In-One printer

    I am running Windows 8.1
    The printer status OFFLINE.
    It has done this in the past and I have been able to correct it by deleting and reinstalling it (at least back when I was running Windows XP and 7.  Possibly at that time it was the DHCP issue pointed out in a previous post.
    Now however, I can remove it and when I add it back, using Control Panel, Devices and Printers, Add a Printer,  it is recognized correctly on the network (shows the IP address I know is in the printer) but when I try to send a test page, I get a pop-up saying it is OFFLINE.  When I status it, it confirms it is offline.
    There is no indication at the printers display that it is offline and it shows it is communicating with the network.

    I can’t give you more than the info in my question about the model of the printer-HP Officejet Pro L7780 All-in-One printer
    I had been using this printer for several years and this has happened a few times in that it required me to delete it and reinstall—that just does not work now. This last time was after I had upgraded to Windows 8.1 however I did that several weeks ago and it has worked okay since then…this is the first time it has stopped working on 8.1 however
    Running Windows 8.1
    I tried connecting via wireless and also switched over to wired lan but got same results (Printer Unavailable)
    Used DHCP but get the same with static ip address
    Cisco Lynksys E4200 wireless router
    Just ultimately get Printer Unavailable when I try to print or status the printer
    When I try wireless, I see the wireless icon bright blue like I expect it to
