How to Identify and Fix Common printer Problems ?

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

If the nozzle check page does not print satisfactorily, you may need to repeat the head cleaning and print the nozzle check pattern again. If print quality hasn`t improved after repeating this procedure four or five times, turn the printer off and leave it alone overnight.
If your Epson printer is printing out faint images, skipping lines, or is streaking your image with lines, chances are you have a clogged nozzle–a common problem many users have with Epson printers. It`s unavoidable that print heads clog over time as small amounts of ink residue dry up and collect in the nozzles.
If you notice white or dark lines in your prints (also called banding), try these solutions before you reprint: Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if necessary. Make sure the paper type setting matches the type of paper you loaded.
The product prints a nozzle check pattern. Check the printed pattern to see if there are gaps in the lines. If there are no gaps, the print head is clean and you can continue printing. If there are gaps or the pattern is faint, clean the print head.
Dried Ink Buildup on the Printhead

If the print cleaning cycle doesn`t work, dried ink may be the culprit. Take the printhead out and wipe the nozzles clean to remove any buildup. Depending on the model of your printer, this may be difficult—some printheads are harder to remove than others.

A printer printing lines on the page are normally caused by a blocked, dirty, or damaged print head. Blocked ink cartridge nozzles, or not removing protective seals correctly when you installed a new ink cartridge can also cause missing lines of print.
Streaking is usually caused by a worn out drum unit or spent toner cartridge. Drum units are a consumable and only need to be replaced after the use of 3 or 4 toners. Not all printers use a separate toner and drum unit.
Dirty or misaligned print heads

Your printer may be printing fuzzy, blurry, or other faint text because of dirty print heads. All modern printers have a self-cleaning mode, which cleans the print heads, and additional internal equipment used in the printing process.

When your printer leaves black lines, the lines indicate that there are excess toner powders on the rollers or transfer belt within the printer. As the paper is moved along by the rollers and transfer belt, any excess powder left on them can result in lines being left on the paper.
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.
Streaky prints call for additional steps

Another way to tell that your print heads are dirty is if your print jobs come out partially printed or streaky. If your printer display says that you`re low on ink but you have a full cartridge, this may also be a sign of a dirty printhead.

Your Epson printer may have failed to recognize the new ink cartridge, or its ink level system has read it as empty. For numerous Epson printer models, there`s a way to bypass this built-in ink checking system through a quick cartridge reset. Raise the printer`s top cover and then hold the Ink button.
Note: After a Power Cleaning, you must turn off the product and wait at least 12 hours before printing a nozzle check pattern and running another Power Cleaning or Print Head Cleaning.
If you have problems feeding paper, try these solutions: If paper does not feed for printing, remove it from the rear feed slot or cassette. Reload it, then adjust the edge guides. Make sure the paper stack is not above the tab on the edge guides inside the cassette or rear feed slot.
Clean the print head, if necessary. Make sure the paper size, orientation, and layout settings in your printer software are correct. Make sure your document does not contain blank pages. If your printer software has a Preview option, you can check for blank pages before you print and remove them, if necessary.

black will not print after cleaning the nozzle head 5 times
ANSWER : There’s way to clear your print head. Go to Youtube site of Jose Rodriquez. He’s got a video on just about every aspect of printing. Put something like a folded shop towel, spray it with Windex, no deodorants etc. just the original Windex, no ammonia D, and some alcohol (not rubbing alcohol but 90 percent or some such). Fold towel into a strip about and inch and a half or so and put it in the cup like trough that the print head follows when printing. Start printer. Let printer just begin. When head moves out of the dock, and unplug the printer. Now you can move head manually. Maneuver head over the towel. Leave it overnight. You may need to do this many times. I had about given up when my print head cleared up. I think you need to see Jose’s video, then you’ll understand better. If you can’t find it or you need more help, feel free to email me. There are other resources, but I wouldn’t go for commercial cleaning kits. That’s just me. And I’m leery of trying to put pressure through the head. I hope this helps. It’s kind of brief. There is a man I found who had written almost a book on the subject. He’s not anxious for his name to be given out however.

One small segment (nozzle check) missing/clogged – cleaning?
ANSWER : You need to buy a “head cleaning kit”. What that does is inject cleaning fluid through the ink port on top down through the heads using a syringe. They don’t cost much. Do a search on eBay for “Epson head cleaning kit” There’s lots of them. Another idea stolen from this site. Gotta love the internet.

Need help for cleaning epson r300, have a kit
ANSWER : Don’t worry about the paper towel. Keep the heads as far to the right as you can and the fluid will just go into the waste sponge underneath. There’s nothing you can damage with the fluid. I wouldn’t worry about the pad that got torn. Just insert the syringe in the nozzle and gently push the fluid down into the heads. This site sold tens of thousands of those kits and I guess the instructions were pretty good because there was never a single complaint.
