Clean officejet print head

Unplug the printer and wait 20 minutes and then re-plug.

You should first try the cleaning procedure that is available through your printer's control panel - .HP Officejet 6600 6700 Printers Fixing Poor Print Quality Problems If that does not work here is a video on removing the HP print head.

INK PROBLEM
Inkjet printers need to be used frequently to prevent ink drying out and blocking 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 than replace the print head.

The Cyan print head nozzle maybe blocked.
If deep cleaning does not fix it then you need a new print head.
The cost of a new print head is expensive and it maybe better to get a new printer.

Hi,

This is not a cartridge issue. IT is Printhead issue. Since you have done the manual cleaning, it is now time to replace the Printhead.

What about print head?.. perform print head cleaning process through tool box, check any back print out? no remove black/yellow print head clean nozzles manually, try it if not resolved replace print head..browse the link how to clean the print head..http://www.ehow.com/video_4974250_manually-clean-hp-inkjet-cartridge.html

If you haven't used the black print option, as in to print without using the color cartridges, then the black print head may be 'gummed up'.
You can try to clean the print head using the 'clean' function, which may work.
You can also try to get the print head to work by using ammonia and hot water. If the cartridge has its own print head, you can use some hot water on a paper towel and set the print head onto the soaked towel for a few minutes. After it has sat for a while, gently dab it dry with another paper towel, and try to use it. If it works, you're done. If not, you can use ammonia to try to clean the print head using the same tactics as using water. Try water first, then ammonia.
If the print head is fixed in place, you have to remove the whole assembly from the printer, and then try to clean the print head using the same method.

The ink on the print head is dry and it is preventing it from printing.
I do my own refill so I buy a refill kit, in it, has 3 bottle of inks and a bottle of cleaning solution. The cleaning solution I use to clean the head.
A place that refill in should carry some kind of a cleaning solution that you can use.
I hope this help you
