I have DCP J515W. I dont use it often but it is usefull with school projects like photos etc. I have it for some years but now there are some problems. If i want print something, there are lot of paper jams but finally i could print everything after few attempts. Yeah, now is much worst. Now i cant even print because printer says "no paper" but i put paper in this. There are also paper jams and i cant do anything... I treid few times but it doesnt work now, but 3 weeks ago it was working. I really dont know whats happened, its just spoiled from day to day... Plz help Im going to clean it tommorow, but whats should i do next?
