Question about HP DeskJet 842c InkJet Printer

HP Deskjet 842C

I have a blinking ink light even though I replaced the ink cartridge.  First I tried Office Depot brand and then HP.

No response at all... I have disconnected power and usb connections multiple times.

My guess is that this is an issue regarding the contacts for the cartridge, if so what next?

    I refilled my black cartridge #15... the color #17 has long been empty, but I've been fine printing in black until I just refilled it. Now, I'm getting the dredged blinking light.

    I tried the suggestion of covering the top right contact (with scotch tape)... but that didn't work. I'm not sure what the "contact" is and which is top and which is right though. I guessed it was those little gold squares on the side of the cartridge. I tried various corners with no success.

    Can you provide any better description of the "covering a contact" solution?

The ink light flashes when the top cover is open...check the switch that tells the printer when the cover is closed.

Make sure both carts are ok usally there is black and colour, sometimes i've seen the spring where cartridge goes break loose, not ecomical to repair, cheaper to replace, modern world, 5 - 10 years ago we would fix but now labour is too high and replacement are too cheap. you could try a little metho and clean contacts on cart and machine

Orange Ink cartridge light is blinking. Tried cleaning the part of the cartridge where the ink comes out. Cartridge is a NEW Office depot cartridge. Was working fine and then stopped after a month or...

Cool, thats the first thing to do, clean the nozzle but i would advice you clean it with rubbing alcohol and then there are a series of gold dots that come in contact with the electronic pins that control the nozzles, you need to clean those too, might be a contact problem...Hope this helps..

Ink light is flashing but i have changed both cartridges

You could try checking the printer ink receptical contacts for damage, or simply clean them, however you can often purchase a new printer that comes with ink, for cheaper then the cost of buying new ink for an existing printer.

HP Deskjet 5740 printer both orange lights are blinking and wont print

  • I replaced both carts with HP brand, no joy.
  • I cleaned the cart/printer connections, no joy.
An interesting aside is that if one or the other cart is removed, the appropriate LED goes out and the other blinks. At least some of the sensing circuitry sees the cart.

Anyone have a schematic of the cart/printer electronics?

Just a suggestion: Have you tried using a different ink cartridge? I have found brand new cartridges to be bad right out of the wrapper.

Hp deskjet 842c blinking ink cartridge light

You have to take off the clear strip of plastic over the copper area, or the printer will not detect it. There should be a green pull-tab on the cartridge.

HP Deskjet 1220C cartridge recognition problem

This happens when the connections on the cartridge get old. Especially when you refill or buy non HP Cartridges, try buying brand new hp cartridges and you might be able to get a couple refill out of them before this happens again.
