Black lines - Televison & Video

Hi!!

If you are making copies on a machine that has a ADF (automatic document feeder)on and your copies come out with black lines on them,but when you make copies from the glass there are no lines on the copies then the small glass on the left,has a mark on it!What i do is put the copy with the black line on,on the glass face up so you can see the line,now,more or less where the black line is on the copy,is where you can look on the thin strip of glass to the left,for a mark or thin line!!Clean it with a damp cloth and no more lines!!

Enjoy!!
