Problem with printing - streaks yellow and green not all colours are printing, not used for some time but new cartridges have been put in

create a doccument with four identical lines of text.
the text should be as follows:
your text in the colour Black, the cyan, then yellow then magentta
see if they print in the colours you used, if they are all wrong then delete all drivers associated with the printer and delete the printer, then follow the install proceedure again to reinstall, if just one colour is wrong the it is most likely a deffective cartridge.

I have personally encountered similar problem in my work.
 
Sometimes when either of the inks overflow at the nozzle, it gets absorbed to an extent into another ink compartment. So that colour affected now prints another colour; the colour that has crept into its compartment, Sometimes it is serious at other times is not. If not serious, usually, after a few solid colour prints the colour affected returns to normal.
 
I do not know how much of a technical person you are, but I will give you the solution to returning that colour to print rightly. Bring out your colour cartridge. Peel off the seal covering top. You will see the holes through which in is fed into it. Get a clean handkerchief, fold it and place over the top of the cartridge. Hold it over a bowl or something. Now place your mouth over the top with the handkerchief in between and blow hard. Ink will discharged at the nozzle. Clean off the ink with folded tissue; always dab not wipe. (At the nozzle do not rub only dab). Now press a piece of folded tissue to the nozzle firmly. It should be blotted with ink:- red, blue, yellow. If any colour is missing you may need to repeat the procedure. Once you get the three colours back, the issue is resolved.

yes you change it and buy new one because toner brush is not supply toner properly

Use original cartridges. Generic or refilled cartridges tend to cause these problems.

Hi,
You need to calibrate your cartridges. To adjust color's in setup cartridges.
It' in printers and faxes.
good luck

I asked the technician at Staples what he thought and he thought it was the ink cartridge. since I was using 3in1 cartridges and it was expensive to buy two; (1) Black with pale magenta and blue plus (2)red blue and yellow,we bought a new printer that uses one colour only cartidges so we can replace one colour at a time and also use a pale blue and pale magenta to get better reproductions. for a little more than double the price we bought an Hp printer Photosmart C7280 on sale with single cartridges. It will pay off, They are a fraction of the cost of 3in1 colours.

If you haven't used it for a long time the ink may have dried up. You can try taking out the cartridge and letting it sit on an hot wet rag for a while to unclog the print heads. Try not to touch the copper contacts on the cartridge. If that doesn't work you may be out of yellow ink.

I found this post to work for me when yellow was not printing on my HP PSC750 after using 2 cartridges: "Well if you want to damage your printer use alcohol. But if you want to make it work then pull the cartridge from the printer and run hot water on a couple of paper towels leaving alot of hot water in the towels. Put some thing under them to keep them from staining your counter top and then set the cartridge down onto the hotwater towel and let the hot water melt away the dry ink and in minutes you may be printing again if this is what it is. Be sure and use a dry paper towel to wipe off the ecess wet before you reinstall the cartridge."

You have either a clogged colour print head or a non-functioning print cartridge (only one colour working). If the printer has separate cartridges for different colours (and black) you can do a partial swap, replacing the ones that have failed, but start by running the command CLEAN PRINT HEADS from the printer options or controller panel, and watch for the quality to improve. You may have to clean the heads two or three times. If no change in the quality after two flushes, replace the cartridges with new ones.

Good luck...

spounds like a defective print head bud. these do wear out and most of the time it will cost as much as a new unit.. Good Luck
