don't know if it's the same problem i had but its maybe worth a try. My paper went in a little, the wheels were turning but it didn't take the rest of the paper or print.
someone replied to my problem, i tried it and its fixed 1st time, for others its taken a few attempts and then worked..
Solution:- Use a piece of thin card, a magazine cover is what i used, make sure its A4 size then try to print something, as the paper starts moving PUSH it through! and hey presto it worked for me, everything printing fine now. hope this helps, let me know how you get on. Garty
