Possibly the print head is getting plugged or the color map settings are changed. Try removing the printer and reinstalling the drivers as well as clicking the "default" settings button after. If this does not fix it, possibly the head itself is ok on a test pattern with low ink but on printing is not delivering full ink in all colors, only yellow, indicating the head is plugging. Possibly cleaning with alcohol would help, place a drop on each place the cartridge inserts on the ink tubes and also clean the head surface where the ink comes out with a Q-tip and alcohol and then do a regular head clean.

One of my cartridges does not work

Start out by running a "nozzle check" in the printer setup screens. If the cyan isn't printing a full pattern, then do a "clean" pass, up to 3 times. If three times doesn't fix the missing color pattern, it's possible that the cart is defective, and isn't flowing ink.

My Epson R320 prints yellow over everything

One key diagnostic you need to perform is a nozzle check. This will tell you what has happened to the other ink colours as much as indicate if yellow is polluting other nozzles.
You can run a nozzle check from Printing Preferences > Maintenance.
Once it has printed you should (normally) see a sort of stepped grid pattern similar to this.
If you can scan or take a photo of the output and the post it as a follow up it'll then be possible to get a bit more of an idea of what could be happening.

Factory reset

This type of problem is typically caused by one of the ink cartridges which is suffering from marginal electrical performance - either the HP92 (black) or HP93 (color) ink cartridge.

Can you perform the 'Self Test Page' test (see below). If this test is successful then this demonstrates the printer is 'generally operational', but if normal printing is still not permitted then either the HP92 (black) or HP93 (color) ink cartridge is likely electrically damaged and may need to be replaced*.

Perform Self Test Page:
1. Press and hold the CANCEL button.
2. Press the COLOR COPY button. Release both buttons.
3. The self test prints. The printed pattern will verify printer is generally functional. Inspect color bars to verify proper nozzle/jetting health.

-- Inspect printed nozzle stair step patterns - verify all ink nozzles are properly firing. Generally, if the Self Test Page prints ok then the printer is functioning correctly and the problem is with the ink cartridges - replace the suspect ink cartridge and retest. Refer to 2nd video procedure at the following link on how to read the Self Test page test (NOTE: HP74/75 cartridges are electrically identical to the HP92 thru 98 cartridges).
http://inkjet411.com/?page_id=579

*Many cartridges eventually do encounter problems or failures. Severe cartridge errors are primarily caused by an electrical breakdown at the cartridge's nozzle plate. Ink *********** or corrosion into the nozzle plate will cause a failure of the tiny micro-electronics resulting in a variety of different error messages being displayed - see picture at bottom of this page: http://inkjet411.com/?page_id=1216

It is suggested to install a new HP92 and/or HP93 ink cartridge in it to resolve the current issue.

Why is my Canon Pixma 4820 suddenly leaving lighter lines through color pictures.

I can't print with the black ink. I performed a print head cleaning, and then I printed the nozzle check pattern. I noticed that the Cyan, Magenta, and Yellow shows up. However, the black checkered...

Simple problem that print head cleaning will typically not fix. The black ink is pigment based so it tends to form more stubborn clogs. Just remove the print head and if you have a steamer hit the black printhead nozzles with some pressured steam. If not available, soak the surface of the printhead in shallow hot water (try not to get the contact wet or be sure to dry them if you do). You can tell if the printhead nozzles are open by folding a section of wet paper towel like 5-10 layers and then soak it, press the printhead surface up and down lightly on the wet paper towel and if the nozzles are open you will see some ink pulse in the black port screen (the colors will also pulse from the pressure of the liquid under the printhead). It's easier than it sounds so give it a try. I've saved 100s of Canon printheads this way.

Note: if you have a really dried out head, you sometimes have to soak from the top inlet ports and the bottom nozzle surface to clear, but unlikely in you case since you had a black cartridge installed with ink in it (this keeps the top port from drying).

The printer cannot recognize the ink

What should I do if the printer will not recognize the cartridge after refilling?
  • Turn on the printer and remove both cartridges
  • Place both cartridges in front of you so that you can see the contact foil, with the nozzles facing downwards
  • With adhesive tape, cover the FOUR upper contact points on the far left contact column of both cartridges
  • Reinsert the two cartridges and close the cover
  • Open the cover again after 2 or 3 seconds
  • Wait until the printer gives you the cartridge carriage (If there seems to be a problem with either of the cartridges, ignore it)
  • Open the cover and remove the two cartridges
  • Place both cartridges in front of you so that you can see the contact foil, with the nozzles facing downwards
  • Remove the adhesive tape
  • Clean the contacts, reinsert the cartridges and close the cover.
  • Most imp.
    If you refill your cartridges more then 3 times,then it is expired and that's why it is not displayed in your printer.For this,you have to go for ma new cartridge.
    or some these steps
  • Try below steps.May be it will helpful.

    1. I used a Q-tip with Isopropyl Alcohol and cleaned the gold contacts on both the cartridge and the mating contacts in the printer.

    2. Then from the Setup Menu, I found a menu called Tools. From there I ran "Align Print Cartridges".

    3. From the same menu I also ran "Clean Print Cartridges"
    4. I then ran a few test prints by going into the Setup Menu and then choosing "Print Report" and then selecting "Self-Test Report". It prints grid patterns in black & white as well as magenta, yellow and blue. The black grid pattern had some missing lines until I printed this report a few times.

    5. I made a few photocopies and now the printouts no longer have large stripes of missing ink as it did in the earlier steps.

Stylus printing striped alternating shades of yellow and green of image

Possible printhead issue.
Please reseat the black cartridge. Let the printer charge like it normally does.
Print a nozzle check pattern. If you see gaps, missing lines or missing colors on the pattern, clean the printhead using the driver. 3 consecutive cleaning cycle is recommended. Compare the nozzle pattern over the last printout. If you see any improvement, you can clean the head numerous times until you get a perfect nozzle check pattern.

Can you help? After changing the cartridges, I keep getting a message about the ink head being incorrect...I am directed to press 'OK' which does not help; then to turn printer off and on again, which...

Cleaning your head might resolve your problem. Perform the below steps to clean the head:

Print Head Cleaning / Head Refreshing If the printed nozzle check pattern is broken, missing, or a specific color is not printed, clean the print head (Cleaning) or print head deep cleaning (Deep Cleaning). Note:
  1. Cleaning the print head consumes a small amount of ink. Cleaning too often reduces the amount of ink in the ink tanks.

  2. Print head cleaning is performed when you connect the power cord. Your machine may perform print head cleaning periodically to avoid clogging.
Overview:
Step1:
Print the Nozzle Check Pattern.
To check whether the print head nozzles are clogged, print the Nozzle Check Pattern.
downicon.gif If the print quality is poor, perform print head cleaning.
Step 2:
Perform print head cleaning.
This unclogs the print head nozzles
Print the Nozzle Check Pattern again.
To check whether the print head nozzles are clogged, print the Nozzle Check Pattern.
If the print quality is still poor, perform two print head cleanings.
downicon.gif Print the Nozzle Check Pattern again.
Step 3:
Perform deep print head cleaning.
This is a more powerful cleaning.

Epson CX3650 printing gaps

Remove ink cartridges one by one and put it back in. If same thing happens, try to do head cleaning and nozzle checks consecutively from the computer.

Start -> Control Panel -> Printers & Faxes (Windows XP) / Printers (Windows Vista) -> Printer Icon (right click) -> Printing Preferences -> Maintenance

You should be able to see nozzle check, click it and follow the prompt. Line patterns that corresponds to the colors of the ink cartridges would be printed. If breaks on the patterns appear, continue with head cleaning. Try to do this about 3 times until all patterns are complete.
