If your printer still can print but with no cyan color then you most likely have a bad printhed. If your cyan ink is not melting it's because it is not using any ink . Get into the "print quality" menu and print the test page. If you get black, yellow, and magenta but little or no cyan then your printhead is bad. Whith these machines cyan is the first color to have poblems starting with weak or missing jets.
You can try to run the "eliminate light stripes" to see if it will help.
Run it about 3 to 5 times. If still not working right, turn the printer off for at least 4 hours and then test again.

Inkjet printers all operate the same basic way. There are differences but the basics are the same for any inkjet devices. Eventually a buildup occurs enough that your printer doesn't print. Cleaning cycles use more and since inkjet ink is worth about $8000 a gallon, this is a expensive way to clean something.
So what can we do to clean this just a bit cheaper? We need to find a suitable solvent that will dissolve these deposits without harming the print head. And the one that works great and is dirt cheap is good old household white vinegar. Next we want to get some lint free (preferred but not critical) paper towels. And a clean clear table top to work. You may want to put down some newspaper. This isn't that messy to do but it can get the odd bit of dissolved ink on things.
Now we take the printer and remove the paper and the ink cartridges and set aside. The print head is a small stamp sized thing on the bottom of the cartridge holder. Take about 1/3 of a sheet of paper towel and wet it with vinegar. Next you want to get the wetted towel under the print head. It should fit as this is where the paper goes you print. The towel is a thicker but it is soft. move the print head back and forth over the towel. When the towel is covered with ink, change it and repeat. Keep repeating this until the towel comes clean. It will only take a few minutes. When the towel is clean then you are done. Replace the ink cartridges and paper and you are ready to print.
You might need to clean the whole print head as well. Open the printer, remove the cartridges and press the lever to release the whole printhead. Place the printhead (while it is standing upright) in a small dish with a few mm of lukewarm water. The dried-out ink will dissolve (you can see this because the water will take color). Repeat if necessary; it may take a whole night before all the dried ink is dissolved. You might then even have the luck that your old cartridges will work again.
Try putting a bit of isopropyl alcohol in the bottom of the cartridge holder where the ink goes through and letting it sit for a couple hours then putting the cartridges back in and running the cleaning cycle a few times.
The alcohol should help dissolve the dried ink in the print head.
Hi Good day!!! Maybe your print head is clooged (red) Then most about 98% are more likely to be an ink clog which just needs to be unclogged using something like print head cleaning solution Basically, if a print head has been left unused for some time... moisture inside the ink begins to evaporate and instead of liquid ink, a thick inky jelly begins to form inside the print head.
When this occurs white lines appear in prints and most people not realizing the problem, will replace their inks... But when that does not work. Some assume they have an electrical fault, and replace their print head, others will replace their printer !
But provided there is no obvious print head damage? In 98% of cases it simply needs a little patience and print head cleaning solution injecting directly into the print head to dissolve the dried ink trapped inside. This will dissolve the clog and allow your expensive ink to flow once again. Most will then print as new.
The reason for banding on the long panels (especially with solid coverage) is the high content of dissolved air in the ink. Dissolved air causes a gradual nozzle drop-out that cannot be stopped unless you do the head cleaning in the middle of the print. Unfortunately you cannot force HP9000 to do the automatic head cleaning in the middle, it can do it only at the end. Manual head cleaning is possible but it takes such a long time that it shows as stripe on a print, and the productivity suffers. Even the OEM HP ink is full of air inside. Our company did a lot of research in this area and we came up with a special ink packaging technique that ensures the ink is 100% free of air. People who tried printing with our ink can easily print 50-foot panels without any nozzle drop-outs or color shift. If you want more info please call us at 1-905-820-8833, www.solventcartridges.com
We also produce portable print head recovery devices and solutions for solvent printer recovery after long periods of inactivity.

Remove the cartridge from the printer. Wipe the cartridge electrical contacts and the corresponding carrier contacts with a dry fabric or paper towel. Then moisten a paper towel and wipe the cartridge printing surface (not the electrical contacts) until clean. Also you can hold the moist paper towel against the cartridge printing surface for a couple of minutes to dissolve dried ink. As a last resort, I have immersed cartridges in water to dissolve the dried ink. Dry all cartridge surfaces with a dry paper towel then reinstall into the printer carrier. Good luck.
