How can i clean my printer nozzels, I know I have plenty of ink but the print quality is really poor so i was hoping to try and clean the nozzels or something to help it to improve. All settings are set as...


Inkjet printers need to be used frequently to prevent inkdrying out in the print head nozzles.
If the print head cleaning maintenance routine does not clear the blockages,then print head needs replacing, but it may be expensive.
It may be more cost effective to buy a later model and better printer thanreplace the print head.

Epson RX620 printer will not print from black cartridge. I have all new cartridges and have run nozzle cleaning 4-5 times. Thanks. Gordon


Make sure the tape is removed from the new cartridges, remove the cartridges, restart the printer, place them back in, you might also want to clean the cartridge contacts if they are dirty.

Try reseting the machine to defaults from the menu.

Trouble shootig


1. You may have a clogged print head.
2. these print head are usually good 4 so many prints then will fail.
3. I heard on tech here swear by placing the head in hot water and unclogging it but I think in the long run that will be a print head replacement. I would contact the manufacturer and ask what cleaning method (manual) they recommend because each print head design is somewhat different whereas the operation is the same.
4. I manually clean with denatured alcohol and a Q tip. Some time works /sometime it doesn't .

Not printing magenta ink and tried cleaning heads already


Hi, one or two head cleans won't clear a clogged nozzle. Try doing 4 or 5 head cleans, wait about 10 hours for the ink to soften and do another 3 or 4 cleans with a nozzle check after each. You should see a gradual improvement in the nozzle checks. If there is no improvement then you need a head cleaning solution such as this one:

Others are available just try googling "inkjet head cleaning".
Note that head cleaning uses between 5 and ten percent of your ink cart's, if any are low on ink have some new ones ready. Hope this helps.

New cartridge won't print


  1. Make sure you removed the tape from the ink cartridge.
  2. Press the <Menu> button on the printers operation panel.

  3. Press the left [<] or right [>] arrow buttons to select [MAINTENANCE].

  4. Press the <Set> button.

  5. Press [<] or [>] to select the cleaning setting you want. Select [HEAD CLEANING] for normal print head cleaning. Select [HEAD REFRESHING] for deep print head cleaning.

    Note: [HEAD REFRESHING] uses more ink than [HEAD CLEANING], so perform [HEAD REFRESHING] only when necessary.

  6. Press <Set>.

  7. Print a Nozzle Check Pattern and perform at least two Head Refreshing if the pattern is not correct.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.

Noise then paper jam then printer head stops abruptly and does not work at all


Clear the paper jam. Then with a cotton pad and some alcohol, clean all the rollers that you see. If you can get to the rear of the printer, make sure that there isn't any paper residue back there, and also clean the rollers in the back. There is a platen (rod that the print head slides on) clean that too.

Then carefully clean the strip in front of the print head.
Also, never move the print head while the power is on, it will cause the unit to get off it's alignment.

Let me know what results.

Does anyone know how to remove print head?


The print head nozzles is clogged but good. None of the cleaning the machine can do will clear it. Been there and trid that. Doesn't work. The clogs need to be dissolved with a specialty clog buster and probably will need to soak at least 24 hours, maybe more. Don't deep clean any more as you will put so much in in the absorbent blotters on the inside of the printer that you will trigger an error code and not be able to print until the absorbant pads are replaced by a service tech for about $100.
