caution whenever you see horizontal line please reduce brightness of your tv for safety of crt. your problem in vertical section only mostly due to loose contact in connector,print or loose components.

I fixed the problem by taking it to a repair shop

SOURCE: horizontal black and white lines are coming on copy

you don't mention whether the document you are copying also appears on the paper.If it does you could have 1 of 2 problems-
The drum cleaning system could be at fault or-
the fuser roller has picked up some **** easy test...... run copies and when the 1st copy edge appears switch OFF. This is a crash stop.Now examine the sheets in there.Is the stripe on the copy before the fuser (Heat) roller? If yes you could have a drum cleaning problem, usually fixed by changing the drum module.If no and the stripe appears after the heat roll, the problem is with the fuser system,dirty rolls etc. There are a number of other problems with stripes, but you have to start somewhere! If the document does NOT appear on the copy, forget all above, could be scan or ROS problem
