Dark horizontal line on canon np6050 copy

Hi, I have one horizontal dark line about 1/2" wide and about 1" from the botton of the copy.

Any ideas what may be causing this?

    Hi Cogz,

    Thanks for your suggestion.

    I have tried running the wire cleaning and what happens is the copy will be cut off at the bottom about a half inch and if you run the wire cleaning again it will not be cut off, run it again at it will be cut off.

    The black line is allways not there when you first run the machine but as you run more copies the line gets darker and darker.

Did you try to run the wire cleaning funcation in the add. funcation mode? It could be that a wire cleaner got stuck in that spot and if you Run Wire Clean it may move it bake to Home Position and out of the way... Good Luck

    The problem is that the cleaner is getting bond up and gets stuck. Also, you proble need the corona wires replaced (6) there are a over looked item that need to be replaced. It's just that your tech may not know how to replace them...... Good Luck

Black stripes on copies using a Canon D1120

Do you use the Doc. feeder? Try to make a copy off the copy board glass. Is the line there? Now make a copy with the adf. Is the line there? If so, you need to clean the small glass under the doc feeder. It looks like a glass ****, about a 1/2 inch wide. Clean it with windex and that should solve your line problem...

Mita DC-1860 horizontal streaks after new drum

You say 'horizontal", but I imagine your paper is actually travelling 'laterally' or or sideways through the machine right? That means that the lines are actually running vertically based on the paper direction.

Is that 2" wide line visible on your drum?
Drum cleaning blade has likely should ALWAYS be replaced with a new drum.

Dose the scanning lamp come "ON" when you make a copy. If it will not come "ON" your scanning Lamp is blown and needs to be replaced. When the scanner lamp blows you will get blank copies..
