QUESTION My Epson Stylus Color 740 printer has begun producing black lines on anything I print out. How can I clean the rollers? It also has problems printing on the reverse side of 240gsm card – the first side is fine. Mary

HELPROOM ANSWER You can use either printer roller cleaner fluid or roller cleaning paper, available from most PC shops and online retailers. Once you've cleaned the roller, the printer should be more amenable to double-sided printing.
