Hello,
When I encounter a problem like this, I:
Take out the black cartridge from the printer Place a finger over the nozzle hole Shake the cartridge again and again, being careful not to take your finger off the nozzle hole Put the cartridge down Take a paper clip and expand both edges so they are sort-of straight Hold the cartridge upside down and press the paper clip edge into the nozzle hole Move the paper clip edge to and from making sure you do not press too hard as to break the cartridge Replace the cartridge into the printer Run the printer to see if the black cartridge has become unstopped up
If this does not work, then purchased a new black cartridge for your printer At times, ink cartridges become dry and seal up, especially if you have not printed in a while
Hope this works, Dana

Just installed new cartridges. won't align


Ink may be new, but their nuzzles may be blocked; depending on manner of storage. To be sure apply a folded tissue paper to the ink nuzzle and press firmly. If the tissue comes off well blotted with ink it means you still have a good amount of ink in it and the nuzzle is not blocked. If not blotted or scantily blotted, it means ink is really low or nuzzle is blocked. To be very sure of this, place nuzzle in a plate/saucer with a bit water so that the nuzzle is soaked. Leave for about 10 minutes. Then apply the tissue again. If still not well blotted it means ink is really low or empty. If new you should return it for a replacement. In the case of blocked nuzzles, the procedure may be repeated over to get results.

Will not print in color, but black cartridge is printing fine. I cannot find where to try and clean printyer head, etc. Cartridge shows to be full.


You find the printhead cleaning facility in the services tab of your print menu box. However I assure you, more often than not this is not enough to get the desired results. If you want best results folow the procedure below, tis simple and effective only a bit technical.

All printer inks are empty on monitor but i have


You did not indicate whether the printer goes through the motions of printing but delivers a blank paper, or wheter it just stands still and doesn't move at all.

So I have to give you solutions to the two scenarios.

1st Scenario
If printer goes through the motions of printing but delivers a blank paper. The cartridge nuzzles are likely blocked. Ink may be new, but their nuzzles may be blocked; depending on manner of storage. To be sure apply a folded tissue paper to the ink nuzzle and press firmly. If the tissue comes off well blotted with ink it means you still have a good amount of ink in it the nuzzle is not blocked. If not blotted or scantily blotted, it means ink is really low or nuzzle is blocked. To be very sure of this, place nuzzle in a place/saucer with a bit water so that the nuzzle is soaked. Leave for about 10 minutes. Then apply the tissue again. If still not well blotted it means ink is really low or empty. If new you should return it for a replacement. In the case of blocked nuzzles, the procedure may be repeated over to get results.

2nd Scenario
If printer does mot go through the motions of printing but just stand still. This could be as a result of either of these scenarios. Usually indicator lights blink continuously in this case.
i. Ink cartridge has developed incompatibility or is incompatible
The Solution is to try an older/another cartridge (doesn’t matter if ink is finished. You must replace cartridge one at a time). If lights stop blinking it confirms that your cartridge has become incompatible or developed incompatibility. Also if your printer is the type that can work with only one cartridge, remove one after the other (closing back the lid/cover) to determine which in the set (black or color) has become incompatible. At the instance the incompatible one is removed and you close the lid, the blinking will stop (for printers that can print with one ink cartridge only). Just replace the incompatible one and start printing again. In most cases the issue is always with one cartridge. But if both are affected, you have to replace both. Because of this type of problem, always keep used cartridges somewhere safe; they come in handy for this type of troubleshooting.
ii. The Cartridge electronic panel is dirty
The electronic panel on the cartridge that makes contact with the cartridge carrier inside the printer is dirty and needs cleaning. This electronic panel is front part of the cartridge with copper “dots”.
The Solution is to try to clean this panel with a piece of folded tissue paper soaked in a bit of methylated spirit. Also try to clean the area in the cartridge carrier/holder that makes contact with the cartridge’s electronic panel (Usually this is more difficult). If you cannot reach it with your fingers, use a stick or something with tissue wrapped around it. Allow to dry well and return the cartridges, close the cover. The blinking should stop if the electronic panel is the issue. Once the blinking stops the printer will print.

My F4180 has stopped printing with the black cartridge. I have checked with different cartridges and have also uninstalled the HP software fully and then made a new installation with all new driver. No...


It's like the ink is not flowing at the nuzzle! To check this you take some tissue paper, fold it so that is is a little padded. Press the black ink cartridge nuzzle (this is the bottom part where the ink comes from) on it. If black in is flowing well, the tissue ahould come out blotted with black ink. If it does not, it means either the ink is blocked or the is finished. Try this with every black ink cartridge you want to test. 

If see the blot of black and the problem persists, clean the "electronic" contact side of the cartridge with tissue soaked in a bit of methylated spirit. Do the same to the area it makes contact with inside the printer.

Then try to print.

Not printing black


Hi

1. Make sure that you have removed the plastic cover from the cartridge nozzle .
2. check if your black ink cartridge is full - put the nuzzle on the tip of you finger if it leaves ink drop then it is full and should print ok , if it didn't leave ink on your finger then it is dry and you should buy new cartridge .

hope it helps
