HP Deskjet F4100 'Error' Lights Blinking - Used 3rd Party Ink

I have an HP DeskJet F4100 All-In-One printer.

To save money, I have for several months been taking my empty ink cartridges to Walgreens and having them refilled. I have had no problems with doing this, until yesterday.

While attempting to print a business letter, both of the "Attention!" lights on the Control Panel that pertain to the ink cartridges suddenly started blinking on and off, and an error message appeared on my computer screen, saying that there was an unspecified problem with the color cartridge.

Assuming that the color cartridge was empty (which I suspect may very well have been true), I removed it. Believing that the black cartridge was probably also close to being empty, I pulled it as well, and I took both cartridges to Walgreens for refilling. They refilled and checked out just fine on the Walgreens system. I brought them back to my office and put them back into the printer, expecting everything to work perfectly.


Despite having disconnected and reinitialized both the printer and my computer several times, and even reloading the printer software, both of the ink warning lights are still blinking on and off and the printer is unusable.

I called HP Tech Support, and the tecnician led me through a series of basic disgnostics that did not solve the problem. Then she asked me if my ink cartridges are genuine HP cartridges. I told her 'No', whererupon her entire demeanor changed, she curtly informed me that HP will not provide technical assistance unless the ink cartridges are genuine HP products. I attempted to ask her another question, which she refused to answer, telling me that the only way I will get further assistance is to pay for it,and even then in order to get the help needed with what she referred to as a "reset", I would have to be using HP cartridges and no other. She also mentioned something about 'firmware', lectured me on what she referred to as the equivalent of taking a Ford engine, shoving into a GMC vehicle, blowing the transmission and then expecting GMC to fix it for free. I asked her, if, considering the fact that I have owned HP products for 20+ years and have never before asked for tech support, she was just going to leave me hanging in mid-air. She said, "I'm afraid I can't help you sir", then hung up on me. Nice, huh?

In Googling the issue of genuine vs. 3rd party inks, I have discovered that this is a major issue and that HP is notorious for its aggressive efforts to keep HP printer owners locked into buying their vastly overpriced in cartridges at full retail

Other than the problem described above, I have had no issues with my printer, and in fact like it a lot..

Can somebody help me to get back up and running, and to be able to continue to use the lesser-expensive ink cartridges I have been using for months with no problem?

Thank you!

PS: Would anyone like to guess how long it will be before I buy another HP product for business or personal use?

    No doubt you're a GENUINE HP mole who prowls the web, finds people with issues like this one and scolds them for having the temerity to imagine that there might be a reasonable alternative to HP's $8,000 a gallon ink. Sorry Charlie, not buying it! Making money is one thing, robbing a captive market blind is another.You must be that guy I read about who sold ice cold beer from an air conditioned travel trailer in the middle of Death Valley in July, for only $15 a bottle. Or the 24-hr. locksmith service I called that time I locked my keys in my car outside my locked house at 3 AM on a winter night, who charged me only $200 to have a 19 year-old kid earning $10/hr. spend less than 60 seconds popping the door lock on the car with a slimjim.

    The above comment was not intended for the OP, it was directed at "leroyal", who offered no help at all and seemed to scold the OP for not using HP ink carts..

She is correct, use only GENUINE HP ink carts, then your printer will work again. THIS IS HOW HP MAKES THEIR MONEY, they don't care about the printer itself.

    Yeah, you guys sound like real Einsteins. If you think HP is bad, wait until you get a snootfull of the rest of the printer mfgrs.

    Try spending some money and don't expect everything to be free.

HOW DO I un-lock the scanner on a Brother MFC 7420?

Unfortunately, the MFC-7420 doesn't have a physical lock switch. You need to turn off the all-in-one and wait for the unit to clear its memory. If the error recurs after you press the power button again, wait 30 minutes and try again. (Note: you will lose any faxes that are in memory. See the User Guide page 11-5 to save this information.) You can find the manual on the Brother support page for the MFC-7420: . Click on the Manuals & Documents tab. Then click on the Manuals on our Online Solution Center for the English version of the manual. The direct link to the User Guide is currently: .

You can also try unplugging the all-in-one for several minutes to reset the error codes. If the error persists, contact Brother if the MFC-7420 is still under warranty (1 year). If it isn't under warranty, consider replacing the unit. The repair costs may be unreasonable.

I hope this helps.

Hp laserjet m1522f error 5 turn off and on

Hi, Error 5 is a Scanner error. When turning the printer on, have the lid up so you can watch the scanner movement. Does it move smoothly? It should go through a warm up and you should be able to watch the scanner movement. If there is a problem with the scanner, there isn't a lot you could do except. The service manual says the scanner assembly should be replaced. If it was my printer, I would try to take a closer look at the scanner assembly and check to see if the scanner unit is bound up somewhere, or maybe a drop of 3 in 1 oil on the scanner rails. Let us know what happens.

Printer won't recognize cartridge

I had the same problem. I'm not sure but I think I replaced the cartridges when the printer was on because I turned the printer off and removed one of the cartridges. When I turned the printer back on it recognized that cartridge but not the others. I turned the printer off again, rmoved all cartiridges and put them back in when the printer was still off. When I turned the printer on again I had no problems. So...try turning off the printer, rmove all cartridges, then put them back in and restart printer. Hope this works for you .

Samsung kicked out hp 3in 1 printer already installed

Don't have your HP designated as the default printer (if possible)when you hook up the Samsung. When the Samsung is hooked up it sees the HP is the default printer. Well it can't have that, they discard the HP drivers. What does Samsung care about HP drivers theres only one printer port setup and thats the USB port you have them sharing. So yes you need to get a second cable. Tim
