Hello inkmasters of the world, I bought an Epson Stylus CX4800 one month ago (my old Epson stylus broke). I'm a student and I need to print notes frequently, when i bought the epson stylus 4800 one month ago my sister who is also in university and myslef printed alot because of our class notes. When the inks ran out I bought refill ink (JetTec 3 colour refill for Epson) and I refilled the colour and the black ink,the refill worked fine 2 times,but when I refilled it the third time no ink was printed on the paper. So due to loads of homework and assignments I just neglected printing my notes so my sister and I didn't print for like 2 weeks. Then I tried again and still no ink on paper when i printed. So i finally went to buy original Epson Magenta ink just to test. But even buying a new magenta ink no red was printed out. So im really confused now can someone please help? Also I've been reading about cleaning printheads due to clogging of Epson Durabrite ink,where is a printhead located on Epson cardridges, is it the little hole thing where the ink comes out? pictures would be very helpful. Thankyou.
