Re: 4002i background

I'm thinking that the light source unit may intermittently not be in the correct position when the doc feeder is operating.

Nathicana,
I believe you are correct. Loosen the scanner drive motor slightly and also make sure scanner rails are lubricated and scanner slides smoothly.[/QUOTE]

When you remove the scanner drive motor you will find a "hidden" screw behind it. You will want to slightly loosen that one too. There have been 2 documented cases where this was the issue here in the US. (yes, one of them was at our office)

Re: 4002i background

I have had two that have had that very problem. ADF only. It can be corrected by adjusting sim 68 to somewhere around +16.
Just play with the settings in Sim 68 and see which direction makes it go away.

It looks like someone messed with the density on copies...but that would be on the whole page

I've seen it before on different copiers (so I don't know if it applies to this one) where the actual scanner unit corner is pressed down so its not level...

Try a print if the problem vanish then the problem is at scaner ( clean optics, check and clean lamp etc) else clean with a brush high voltage board . If it remains replace it.

Re: 4002i background

I saw this once on 6002i and it was the scanner lock position was in the shipping mode.
I couldn't believe it till I took it out of shipping mode .
Some installer screwed me.
