Ok. The only reason I asked is that many will buy the generic ink refills. There is nothing wrong with that. They may work with the printer but the ink tends to dry out much faster.
I am not familiar with that exact printer, there are way to many types to keep track of. If it is an older printer, 2 to 3 years or more then it does sound like the nozzles are clogging. If the printer is not used everyday and or the current ink cartridges have been in it for some time this can lead to nozzle blockage as well.
Found online information that states there is a cartridge sold that contains a cleaning liquid. But they seem to be hard to come by. Others have had success with a very
soft lite application of compressed air.
