Dirty laser glass? Try the magic wand.

i dont think that the laser glass is dirty because scaning to pc gives good image, and printing from pc gives the same problem, so it's not the scaning laser glass problem

thanks for the idea

Is the strip completely blank? Does it always appear in the same place?
If so, it is possible that something is clogging the developer roller or that the laser glass is dirty

the strip yes is completely blank, and also it always appear in the same place,

thanks i will check

Both mentioned already. Pls try harder.

i tried scaning to computer it gives good image
i tried printing from computer it gives the same problem on printed document,

i think it can be the drum unit that must be changed.

The picture you shared is REALLY small, so it's hard to make a proper determination. Like others have suggested, I'm leaning towards junk caught in the dr blade leaving those void areas. It's very common on these for dust and junk to get caught in the blade because this model recycles the "waste" toner.

One other thing that I have seen happen on these is the foam strip attached to the erase lamps starts to breakdown because of the age. I've had at least 2 occurrences where a small piece of that foam was hanging down from the erase lamp board and blocking the laser path. It took me quite a while to find that issue, because it's not easily seen unless you think to bend over a bit more and look up.

Thanks for you reply, the picture i shared was not small in original, it's only when i upload it to this forum, anyway here is other pictures

In these models, Drum and Developer both can make this problem.

What did you replace???

I guess that I have to point out here that the laser slit glass and the scanner slit glass, though performing a similar function, are two entirely different items. I really hope that this is result of a questionable translation, because if it isn't you have a long way to go to become a technician.

Hi,
1. Clean Laser glass not scanner glasses
2. Change Developer. Because it seems it is not realy black, only grey and foggy and somebodey wrote it already: There is something under Doctor plain (white lines).
3. Change drum and main wiper (together with developer)

the laser has nothing to do with the scanner, remove the developer unit, if the developer is uniform throughout the magnetic roller, the problem has to be in the laser glass, remove the drum and check that the laser glass be clean

I have only given my opinion of the problem and I have requested more information, I do not understand the negative reputation

For a bizhub 350? Don't think that is correct.
