You will have to do an external clean of the print head.
Remove the cartridges.
Remove the print head from the printer.
Be careful not to touch the metal contacts on the head.
Boil some water, pour 1/4" (6 millimetres) of water into a saucer.
Immediately place the part of the print head 'where the ink comes out' in the water.
Leave in there for 2 minutes.
This will clean any junk out of the holes.
Place the head on some tissue paper and let the paper absorb the water.
Do not rub the print head with the tissues!
Replace the print head back in the printer, replace cartridges and run the setup - alignment.
This works most times unless the print head is faulty...

How to make pictures sharper

Regarding your recent inquiry about the HP 02 cartridge print quality/missing color issue in your HP Photosmart C5180 printer, let's first make sure that the printer is firing all 6 cartridges correctly. Based on your problem description, it sounds like there either an air bubble in one of the printer ink lines or a portion of the PRINTHEAD* could be dry, so you should first perform a "Clean PrintHead" procedure from your printer's 'TOOLS' button on the control panel.

NOTE: If one or more the colors were previously dry fired during printing (i.e. if you continued printing using only a few colors to one, air may have been accidentally ingested into the ink lines between the cartridge(s) and PRINTHEAD. To recover from this problem, you may have to run the "Clean Printhead" procedure 2-3 times. Depending on your printer model, refer to the applicable video procedure: without 1-9 keypad) with 1-9 keypad)

However, if you have already attempted to clean the printhead and one or more colors are missing, then it is suggested to run the 'Tap 43' printer diagnostic test to ensure the built-in PRINTHEAD (inside the printer) is functioning properly* without 1-9 keypad) with 1-9 keypad)

Refer to the HP Printer Diagnostic's document (PDF file) at the following link for advanced diagnostic tests for your printer model:

To completely verify the ink lines are clear and working correctly, print the "INK RECOVERY TEST PRINT" from our Test Prints page (intense color drop pattern):
As an option (to help conserve ink), you could just run the Self-Test Report (under 'PRINT REPORT' menu), this will verify nozzle performance and that each color is firing a solid band of color (i.e. you should not see any bands or missing lines in the pattern). This is also a good test to help isolate which color (or portion of the electronic PRINTHEAD*) may be causing the issue.

If a problem persists (poor print quality/nozzle misfiring/missing colors, etc.), then we suggest that you thoroughly review the steps outlined on our HP 02 support pages, including printer cleaning and service station cleaning. It is suggested you refer to printer manufacturer instructions first as the Inkjet411 procedures are provided for informational purposes only. A dirty service station can cause poor image quality and/or ink cross-contamination between different colors. (HP 02 main page)

If this does not remedy the problem, then you may have a defective PRINTHEAD* in the printer (worst case scenario), unrelated to the refilled cartridges. As this printer writing system (found on 58 different HP printer models) is between 10 and 12 years old there is a very good chance that the PRINTHEAD has reached it's END OF LIFE.

*The HP 02 ink series printer models have an electronic PRINTHEAD within the base of the carriage assembly (responsible for pulling ink from the 6 ink cartridges and then firing the ink droplets onto the paper) - the HP 02 PRINTHEAD typically has a maximum life of approximately 25,000 pages (~15,000 page average). Unfortunately, the permanent PRINTHEAD is not replaceable.

CAUTION: Be advised, the use of HP 02 compatible/clone cartridges (i.e. sold thru the internet from overseas) are known to be problematic and may cause printer errors and/or permanent PRINTHEAD damage due to incompatible ink formulations (i.e. contain Volatile Organic Compounds which are known to damage the built-in PRINTHEAD). We do NOT suggest using or refilling these types of ink cartridges.....refilling of HP 02 or HP 02XL original/genuine ink cartridges is only suggested!

HP 02/02XL Ink Refilling Services & Additional Cautions:

If you need to purchase a new HP 02 (or HP 02XL) ink cartridges, we suggest you try a USA remanufactured ink cartridge from as their ink cartridges typically have the lowest cost in the USA and have a high reliability rating (free shipping for all orders above $20).

We trust this helps explain the issue your printer is currently experiencing. For any additional questions please contact us directly:

Stylus printing striped alternating shades of yellow and green of image

Possible printhead issue.
Please reseat the black cartridge. Let the printer charge like it normally does.
Print a nozzle check pattern. If you see gaps, missing lines or missing colors on the pattern, clean the printhead using the driver. 3 consecutive cleaning cycle is recommended. Compare the nozzle pattern over the last printout. If you see any improvement, you can clean the head numerous times until you get a perfect nozzle check pattern.

Printer is only printing one color

possible printhead issue. Cartridges maybe outdated too. If you haven't used the printer in a while, the inks on the nozzles will dry out, thus clogging the printhead nozzles. If your cartridges are installed over 6 months now, it may be outdated. Replace cartridges if they are already outdated.
Do a printer check by printing a nozzle check pattern from the printer. To print a nozzle check pattern, turn the printer off. load 10 sheets of regular paper into your printer. hold down the paper button while you turn the printer on, keep on holding down the paper button. let go of the paper button when the powerlight is already blinking. If there are gaps or missing colors on the nozzle check pattern, please do 3 head cleanings. compare the nozzle check pattern over the last printout. If you see improvement on the pattern, continue cleaning the printhead till you get a perfect nozzle check pattern.
If there are no improvements, your printer may need service.

The printer has a one year warranty from the date of purchase. Pls call epson if your unit is still under warranty.

Canon IP90 portable . No ink printing.

Have you performed a nozzle test? If one or more of the colors is missing when you do the nozzle test, the printhead itself is likely in need of replacement.

Before considering replacment, perform a clean on the printer. Due to variations between mac and pc, please see your documentation / support files on how to perform the clean on your printer.

After performing the clean, again perform the nozzle check to see if the problem is resolved.

If still not resolved, remove and re-install any cartridges you recently replaced to make certain they are installed correctly.
