HP 750C PLUS PLUGGED INKJET CARTRIDGES

DOES ANYONE HAVE AN EFFECTIVE METHOD OF GETTING PLUGGED/DRIED UP CARTRIDGES TO WORK. I CONTINUALLY HAVE PROBLEMS WITH THE 750C PLUS DRYING UP IF I DON'T USE IT ON A REGULAR BASIS. ANY SUGGESTIONS? THANK YOU.
First off I assume this is a Designjet 750. If so the service station on the left side is responsible for keeping the cartridges from getting plugged/dried up. Make sure the rubber parts which are directly below the cartridges are in good shape and free of any debrie. Also keep in mind that these cartridges have expiration dates which are printed on the lower portion of the cartridge. If expired they will fail more often then not. You may also want to make sure you keep the plotter on at all times and that the carriage assembly is always all the way over to the left when not in use. When they do get plugged about the only thing you can do is place the printhead in a bowl of hot water and let it sit for a while.

I used to have an eight colour inkjet which was based on HP cartridges. There were no cleaning heads in this beast and the engineer went through a very useful cleaning routine which has proven useful on a variety of inkjet printers since including Epson, HP and Lexmark.

Start off with a new lint free cloth such as a Jaycloth - cutting them quarters saves cost.
Soak the cloth in hot (not boiling) clean water and wring out so that it is damp but not dripping.
Dab the clogged cartridge spray surface onto the cloth, pausing for a few seconds before sliding the cartridge away and off the Cloth. It is important that you slide the cartridge in the direction of the two spacer ridges on either side of the perforation array as this will help prevent any fibres from causing further blockages.
Repeat this process on a clean area of cloth until all the dried ink has been cleared and sliding the cartridge no longer leaves behind a thick line of ink.
Once all the cartridges are cleaned in this way, insert into the printer and run a test as usual. You may have to carry out this routine more than once to clear a stubborn hole but as long as the cloth is hot, it will eventually clear.
A coulple of points:

Dont use soap or detergents (i saw someone try this and its not a pretty site when the cartridge goes back in!)

Always dab and slide on a clean area of cloth. The cloths can be rinsed and reused again.

Consider relocating the printer away from radiators, windows, doors or air condition vents as the drafts and heat from these sources will thicken the ink in the perforation matrix and clog up quicker.
