Avoiding print head burnoutWritten by Barry Shultz
The print head, which is engine of your printer and which may or may not be located inside cartridge, houses hundreds of tiny, delicate nozzle assemblies. Each nozzle assembly consists of a tiny ink chamber, a resistor that controls flow of ink, walls that guide ink to right position, and a nozzle plate with a hole, from which ink will be sprayed onto printer paper.After each time a nozzle fires, a new supply of printer ink is automatically drawn into its chamber, to be ready for next time. When printer is told by computer to print a page, copper circuits on end of ink cartridge send a message to nozzle's resistor, which then heats nozzle's ink supply just enough to cause it to expand and to force a drop of ink through nozzle onto printer paper.
| | Tips for refilling printer cartridgesWritten by Barry Shultz
1. If this is first time you have refilled always start with a refill kit. The kits include all tools, ink and instructions necessary to successfully refill your cartridge. If you find that you can't do procedure and just don't like refilling you are not out a lot of money. You would be surprised how many people order 4 pounds of bulk ink and don't have a clue what to do with it. 2. Do not let your inkjet cartridges dry out. You should be refilling them when there is at least a small amount of ink to keep print heads moist. If you have a dried up cartridge you can try soaking print head (if it has one) in our FLUSH solution over night. If sponges are dry you can inject a couple cc's of FLUSH and let it sit over night. 3. Refill in batches if possible, testing each cartridge as you go along. See #12 for storage solutions.. 4. Always have a spare cartridge that works. Don't think that just because you had a successful refill last time that you will again. Inkjet cartridges are unpredictable. They don't need a reason to fail. 5. Do not buy a large amount of ink unless you are confident of refilling process. This was already mentioned but I think it deserves a line of its own. Get a refill kit first until you're comfortable with refilling process.
