HP 6940 power, resume, right cartridge lights flashing continuously

I found my 6940 HP with power, which takes up and fires right cartridge like crazy. I did everything that I could Google to try to resolve the problem, several times in the course:

  • Power cycle, including remove the power cable from the plug
  • factory reset (report, press Cancel x 3
  • Remove/replace cartridges
  • move the rear cart & more
  • start without installed black cartridge
  • start without installed color cartridge
  • start without any cartridges installed
  • Check and check for paper jams (he was never that I can tell)

In each case, my method was.

  • Remove the power plug from the back, wait 15 seconds to replace.
  • Try something from the above list

In each case, the printer works fine for a few minutes. It's the ping requests, it is accessible via the integrated web page and a test page can be the printer. In each case, after a few minutes, the lights flash, and the printer is no longer pings or via the web page. When the lid is raised, the bar that prevents the cartridges come off, is stuck in the up position (preventing removal).

I'm afraid that the thing bought the farm, but I've always been happy with it and will not replace it (all they seem to do today are these monstrosities multi-function) if there's a chance someone knows something that can fix.

Darryl Hello,

I noticed your post about your problem with your Deskjet 6940 showing you lights flashing lights and working for a few minutes at a time before the return of the cycle. I want to help you as best I can. I see that you already have some troubleshooting.

I have studied this issue and have found some documents of troubleshooting I recommend search and try anything you have not yet tried.

  • DeskJet 940c: 940c cartridge light flashing

    I just print something yesterday and nothing happens (having previously printed a page). Looked at printer - cartridge light flashing. Used HP printer doctor, open lid and transport moved to tricolor cartridge so resumed there and in. No difference. Then taken and in the black print cartridge and carraiage moved to here! Repeated several times to no effect. Never had this problem before and I have no cartridge spare at the moment. I'm stuck for a solution!

    Hello

    For some unknown reason, it started working again after just checked to make sure that the USB cable is firmly connected the printer (it is).

    On the surge protector, I have always used an and reven didn't think that (not that I have now but I'll keep in mind of course). I used the guide you mentioned to troubleshoot not that it helped when I used the guide before it started working again after checking the USB connection. I intend to buy a new printer I've had this one since 2002 about, so I was not eager to buy new cartridges that might not even work. I have two in one I have a flat bed scanner and I like the look of the printer HP OfficeJet 8100.

  • Cartridges lights flash on full cartridges

    My officejet pro K8600dn shows lights flashing on the printer cartridges, while the cartridges are full. Putting the printer turned off and didn't help. When I do a very strong push on the cartridges, that the lamps are going out and I can print. Then the lights flashing again. By the way: I only use original HP cartridges.  My desktop computer HP Pavilion and OS Windows 7 pro 64 x, has already the latest version of the software and the driver, but it does not solve the problem.

    Using authentic HP inks? I would clean the contacts on the cartridges to make sure the accumulation of ink was not causing and delivered with the printer being able to read that the cartridges are inserted correctly. If after manual cleaning, you still have a problem, I would like to do a hard reset of the printer. A hard reset will attempt to restore the printer to a known working condition and no user parameters are lost with a hard reset. First of all, start by cleaning, I know the model presented is not the same, but the cleaning cartridge is what one wants to follow.  To do this:

    1. Open the cartridge door.
  • printer all-in-one PSC 1315: check the ink cartridge light flashes

    the last time I printed the page came out very laboriously and slowly. The next time I turned on the print cartridge check printer is flashing. My specific request is the medium that contains the cartridges is a little loose (up and down) approximately 1/16 "or more. Is this normal? Thanks in advance for any advice...

    It is normal that there is to play in the transport. Slow printing is caused by the failure of one of your cartridges.  The document here may help address the error lights.

  • LAPTOP POWER LIGHT FLASHING CONTINUOUSLY

    Hello everyone,

    After a good time with a Presario laptop I just bought an HP Pavilion Notebook PC g6-2004tu. Since last week (the second week since I bought the same) I noticed the light of battery on the right side (next to the CD Combo drive) which turns red when he was charged, began to blink once the adaptor cable is removed and even the windows are arrested & closed the laptop cover.  Of course require all of you experts could advise, suggest and help in this regard.

    Thanks in advance.

    Go to the HP website, select Support and drivers, either enter your computer model or to leave the website to detect.  From there look at the troubleshooting information for your laptop.  HP generally uses flashing lights like this to show with the laptop hardware problems.

  • HP Officejet Pro K8600: Power light + resume light flashing after printing only one Page

    After trying to print a document of several page, the printer produced a page and then the power light and the resume light (page feed) Flash. I also tried to print multiple copies of a page, but that leads to the same result.

    I can get the lights extinguish by turning printer off then turn it back on. But it will always print that one front page the same lights begin to Flash. I did six times in a row just to print a six page document.

    I went through all the steps in troubleshooting HP software. Not like searching for cleaning print heads, re-seats cartridges, etc., fragments of paper. Nothing seems to work.

    @Bob_Headrick

    Thank you for your response. However, none of the suggestions could solve the problem. ALTHOUGH the light guide troubleshooting that you provided was close to the solution.

    I came across the solution by reading the PDF manual for the printer. On page 77, it describes the power led + resume light flashing. One of the causes for this using EXPIRES of CARTRIDGES of INK, CARTRIDGES RECHARGEES or NON HP CARTRIDGES.

    WARNING: It is important to note that if your printer is still under warranty, DO NOT DO THIS. HP notes in the manual using this substitution can void the warranty against damage caused by the use of faulty ink cartridges, obsolete or not allowed.

    SOLUTION:

    While the power light and button resume flashing, press and hold the power button and press the button repeat 3 times. This replaces the "apparent" internal error message to use the cartridges you have installed. It may also cause a print cartridge alignment page.

    MY OPINION:

    It is important to note the HP cautioned against it, it FIXED MY PROBLEM IMMEDIATELY! I know that the cartridges that I have installed are in agreement. Like many HP owners out there, I take advantage of sales and have stored on cartridges. I guess some may "expires" before you install it. In my view, the idea of "expiring" cartridges also somewhat falls into this column to "How can do us buy more ink?" What kind of market we create where it's cheaper to buy a new printer than to buy a new set of cartridges/toners? BUT it's a slippery slope... let's not go there.

  • Satellite 2805-S201: AC power light flashes orange 8 times

    Hello

    I worked on a Satellite 2805-S201 and everything was fine until I put a PCMCIA wireless with 3, 3V power.
    After that, the AC power light flashes orange 8 times and recycle.

    It comes with power supply, battery, AC and no battery installed, etc. If I pull out the power plug and the battery and then put both when AC is green and the battery may charge. As soon as I push the power button, I hear a light click on the right side of the device and then it goes into the amber cycling power.

    Bulletins of support mentioned that the card could get damaged, but did not mention the unit itself.
    No, the PCMCIA card is not always connected

    Any thoughts?

    Hello

    The flashing provides a micro code which refers to the hardware failure.
    But please don't ask me what might mean this code because in my opinion, only an authorized service provider can be read and can check in his manuals and documentations.
    But it is of course, in most cases, it s a hardware problem of motherboard! ;(

    Perhaps the external PCMCIA card was not totally compatible and damages of something on the map but it's only my personal suggestion to ensure what s bad hardware fault diagnosis would be necessary.

  • 32D1334B LCD TV - not light power light flashes red & Green

    I have a Toshiba 32D1334B LCD TV, it used to work perfectly well and then all of a sudden, it will not activate.
    When I plug in the TV, the power automatically light flashes red and green permanently. There is no way to turn on the TV; the screen remains black.

    I had to take off the back, watched and deleted all the parts, but can not see the obvious problems. I also a multimeter and power to the various sections of the TV is, but that's as far as my electrical knowledge goes!

    I don't really know what else to try, but I am very reluctant to throw away the TV that I know it's probably a unique piece that needs to be replaced to fix it. I searched online and others have reported the same problem exactly, but it had not resolved there always. Unfortunately, TV is more under warranty... If anyone has any suggestions or can provide any help, then it would be greatly appreciated!

    Thanks in advance.

    If you find out how to fix it please let me know because my tv is the same.chris

    Hello

    This means that your mobile doesn t boot with AC/DC adapter and AC/DC adapter too?
    Really strange what s

    Have you tried to remove the battery and the AC adapter? If you remove the two you should an hour and then reconnect the two. Maybe it will work.

    If this isn't the case, it seems to be a hardware problem. You must contact an authorized service provider, you can give them a call to speak to a technician.
