I have a HP Deskjet 6940. When I print I get spots on my paper. I have read the reference guide and have not found the information about cleaning the heads. On other printers it will tell you on how to do this under the cover, but nothing is there. It is connected to a iMac. Any suggestions on what I can try. Thanks JV

Print heads become blocked for a number of reasons, but the most common is simply that the ink cartridge has dried out, and so has the print head. Anyway, here are a few hints and cleaning methods that MIGHT get things working again.
Never let the printer stand with an empty cartridge. Either fit a fresh one, or seal the print head unit in a plastic bag with a few drops of water for humidity.
If the print head has become clogged and the printer's head-cleaning cycle won't help (run it 10 times if you have to) you could try these things:
Soak the print head in hot water then leave it overnight, then try it again
If you have access to an ultrasonic cleaner that will take the printhead, use that. (These are used by jewellers and other people which have to clean small, intricate parts)
Buy some Isopropyl Alcohol and soak the printhead in that overnight. (You can get it from the chemist)
Use a Mr Cuppacino (or your Espresso machine). It's a small kitchen appliance which creates a jet of steam for frothing milk for making a cappuccino. You can use the jet of steam to blast the print head. But be careful that you don't melt things -- short, sharp jets only.
Each time you try a cleaning method, use a damp paper towel to gently wipe and dry the print head area.
Put a teaspoon of water in the bottom of the empty cartridge and try the cleaning cycle a few times.
the printer needs servicing.the steel rod on which the cartridge carriage moves sometime oiling that steel rod makes it proper other wise the whole printer needs to be opened and the cleaning and servicing needs to be done.
