The red and the green lights on my HP 842C printer will not stop blinking. Also when I open the cover the ink cartridges stay hidden off to the right side.

The Epson printer won't recognize the ink cartridge when you have dried or empty ink, outdated printer drivers, ink cartridge not installed and much more. You can easily fix the Epson printer not recognize ink cartridge issue with simple steps.





·Remove and Reinstall the ink cartridge

·Check the ink cartridge

·Update printer Drivers



If your Epson printer blinks the Red or green lights, that means your printer has some other technical issue. You can fix the Epson printer lights blinking issue with these methods.

ts stop printing and the LED power light green and orange at the center blink, like there is a paper jam.

My C60 Epson Stylus printer is not printing. First of all the paper jammed, I pull the paper from the front and since then the catridge holder is not going to the middle to print. also the green light keepon flashing and the red light stays on. I need your help.

Hi:
If you open the door on the top of the printer, while it is powered on, the ink cartridges will move to a spot that shows you the status of your ink.. There are little cartoon pictures of the cartridges with smiles or frowns to tell you if you have an empty color or black cartridge.

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

Turn on the printer.
lower th epirnter's output tray, pull out the extension, and open the cover.
press and release the ink button.
if your ink lights is on or flashing, the printer head moves to the left, and the cartridge that need to be replaced stops under the ink out mark.
open the cartridge cover
Pinch the back tab of the empty cartridge as your left it out of the printer.
shake the ink cartridge 4 to 5 times while it is still in the package.
unwarp the new ink cartridge and lower it into the holder. Push down gently until the cartridge is firmly seated.
repeal the procedure if more than one ink cartridge is out.
close the cartridge cover.
close the printer cover and press the ink button.
The green power light flashes and the printer makes noise. charge takes about a minutes. When it's finished, the green power light stops flashing and stay on, and the red ink light should go out.

The light you describe is the ink light.
When that light is blinking, try this.

Turn on the printer. Open the front cover and look at the carrier for the ink cartridges. There is a white arrow right above the latch for the color cartridge.
Once the carrier stops moving, the white arrow should be pointing to a symbol which represents the problem (the reason the light is blinking.) Examples are low ink black, low ink color, sick black ( replace ) , sick color ( replace ).

IF you have just replaced your black cartridge, you might need to replace your color cartridge too.
This printer will not work without both ink cartridges installed and full.
You cant print with a full black and an empty color cartridge unfortunately, even if you only want to print black.

Hope this helps!

My HL-5240 did the same thing, Here is what I found:

Look at the back of the printer. Pull down the back cover. Look to the right and the left of the exposed internals of the printer and there should be another handle/knob you can pull down. Pull these both down simultaneously and check to make sure there isn't a piece of paper in there! This was a shock to me! My office printer was held up for days until I found this hidden door in the back! I felt like an idiot that it was from a stupid paper jam!

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.

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
