Cleaning inkjet cartridges

[celiboy]

Hi there

I bought a new cartridge for my Lexmark Z25 about 4 months ago and I printed some stuff at that time. I basically only print maybe 50 pages a year. I just tried prining something and nothing was printed on paper despite having a full cartridge so I know the thing is dried up. Is there any way to unclog, rehydrate the cartridge? My printer monitors the ink levels and it rightly says they are full so I know it's not a case of running out of ink.
