Ciss ink won't work on hp c7280

Depending on printer brand and model, there are lots of ciss (continuous ink supply system) solutions to buy.<br /><br />Bare in mind, though, if you are planning to use printer heavily, there are other considerations you should think about:<br /><br />1. If not used regularly, an air bubble may occur and it takes a while to pop it up. Also ink may dry in certain area and it's a mess to resolve.<br /> <br />2. The ink supply (depending on supplier) may not be good as the original; color depth and durability wise.<br /><br />3. Cartridge recognition problems may occur from time to another, so it must be removed and inserted again.<br /><br />4. CISS system usually have a chip to fool the printer and it may fail with any liquid contact.<br /><br />5. ink pad inside printer fills quickly on heavy use, thus its wise to direct the pipe into an external tank (found inside and in the back of printer for Epsons) <br /><br />In conclusion, if you intend to have more than 100 pages/month, consider compatibles or refillable cartridges. ciss is good for +200 pages/month.<br /><br />e.g. (epson rx685 blanks out all 6 cartridges except for the black after 10x15 photo's in with high quality enabled)<br /><br /><span style="font-style: italic;">Please note that these tips are based on experience with 4-6 cartridge systems for Canon and Epson printers.</span><br /><br /><br />If you find this informative, kindly <span style="font-weight: bold;">vote positively</span> for me to continue sharing.
