I tried cleaning HP heads with an ultrasonic cleaner. INK has to be soluble in the cleaning fluid. And if it's dry inside, May never get enough backwards thru the hole to wet the dry stuff. Can't say I was successful. mike -- Return address is VALID. 500MHz Tek DSOscilloscope TDS540 $2200 http://nm7u.tripod.com/homepage/te.html Wanted, 12.1" LCD for Gateway Solo 5300.

Windex seems to work well as a cleaning solution for print heads. -- John Miller email address: domain, n4vu.com; username, jsm Surplus (FSoT): New Conn V1 double trumpet case, no logo Tektronix 465B oscilloscope New leather business case |

I just put about 1/2 inch of water in a small pyrex dessert-sized dish, heat it in the microwave till it boils, wait about 10 seconds and then place the cartridge right side up in the hot water for about 5 seconds so the print head gets wet, but not the main ink portion of the cartridge. If that doesn't clear things, I repeat it. Never had it fail, but I never wait until the cartridge is totally dry before I clean and refill. Used this on Cannon, Epson, Lexmark, and HP cartridges, refilled some 20+ times. H. R.(Bob) Hofmann |

hi
I have never used that method however I have used this method with great success I had a couple of hp45 black carts and were blocked I filled the sink up with very hot water and filled a syringe up and put it in the hole at the bottom of the carttdridge and began to squeeze the water into it . I kept doing this until I had clean water coming out in little jets like a rose of a watering can then I shook it and left it upside down for a while then filled it with new black in and sealed it it worked a treat for me .. ( however you need a syringe that fits into the opening tightly to make a water tight fit , , and be careful as if you put too much pressure into the cartridge you may blow off the head ) let it dry before installing it . my friend used this method for his Epson cartridge and again that worked for him .... haven't really had much luck at servicing a colour hp cartridge . due to the sponge . Some suggested IPA will soften and dissolve dried ink which I know is true but I don't know if it would break it down small enough to pass thorough the head with out blocking it . hope the info helps de Paul de Paul "mike" wrote in message ... nospam wrote: Any one have any experience with cleaning color inkjet cartridges with an ultrasonic cleaner?
