How to Identify and Fix Common printer Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced technical support :

The yellow nozzle “might” be plugged. Wherever the print nozzles are, carefully wipe them off 2 or 3 times with a paper towel wet with isopropyl alcohol. This Usually dissolves the clog.
The primary culprit in the problem of clogged printhead nozzles, whether in Epson printers or otherwise, is air. Air blockages are fairly common, particularly because nozzles are becoming smaller, with every little bit of technological advancement. The next big culprit is, of course, dried ink.
The ink levels may be low and you may need to refill the ink. Visually check the ink levels. Also make sure you filled the tanks with the correct colors of ink.
The printhead could be clogged, and you might need to clean the printhead several times to restore print quality. Use an automated tool from the printer control panel to clean the printhead.
Why is my printer printing yellow not red? It is most likely that your image is yellow where you were expecting it to be red and you may also notice that blue parts of the image appear turquoise instead. Both of these effects are caused by a lack of magenta ink/toner on your prints.
Turn the printer on at least once every two weeks to automatically clean the print head and prevent the nozzles from clogging. If you do not turn on the printer for a long time, the printer may malfunction.
The reason behind this problem is that some of the old material remains in the extruder due to the lower temperature needs of the new material. As a result, the old filament will not melt completely, and the residue left behind may cause the nozzle to clog in the long run.
Make sure the Black/Grayscale or Grayscale setting is not selected in your printer software. Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if necessary. The ink cartridges may be old or low on ink, and you may need to replace them.
Black, cyan, magenta, or yellow vertical lines or streaks can be caused by a dirty corona wire, a toner cartridge, or the drum unit.
If you`re still experiencing quality issues or printhead errors, then there may be other problems at play. Before taking any other actions, it`s recommended that you clean the printhead and ink cartridges four or five more times.
The Cause of Clogs

Printheads clog because nozzles get blocked by either air or ink. Clogs usually happen when: You keep printing with depleted ink cartridges. Using empty ink cartridges can result in air bubbles that can clog your cartridge and/or printhead.

If your PC or the LCD screen on your printer is telling you that your ink cartridges are full but no ink is passing through to the paper, then it`s most likely that you are dealing with a clogged printhead. Blurry documents and images that appear faded are also signs that it`s time to remove the excess ink.

yellow not printing
ANSWER : On my Epson Stylus Photo R285 The yellow is tinted with black but thenormal nozzle cleaning restores a proper yellow. This is fine except the next day the yellow is tainted again, unless I waste more ink doing the nozzle clean again! As these two colours are side by side in the head, does this mean the print head is faulty?
