KM/CS 300i lite print/copy

[Gar the pilot]

I have a cs 300i with 88K using OEM toner that prints even, but lite prints or copies. My customer had not noticed the problem yet and they were too busy for me to take time to look into this. I don't think I am being too picky as my Boss thought they were lite too. With it being so even I don't think it's dust on the laser slit or anything like that. I was there to fix a deffernt machine but delivered and installed toner on this one. I thought at first it just needed to tone up, so I went to work on the other machine. When I got back to the 300i, it was barely better. This is my only 300i out, we do have other Mita's of the same class. Just not sure of anything weird about this one.
Thank You

The KM-300i is a mono-component development system, so toner density is never in question. Either there is toner, or there isn't.

More likely it is a transfer issue. To be sure, emergency stop the machine with a sky shot across the drum. If there is a significant amount of toner still on the drum you're losing transfer. It's common on other machines of this era to have the transfer roller pop out of the bushings. I've had one of those really helpful endusers pop the transfer roller back in, but they never noticed that there is a spring at each end. If the front spring is gone, the transfer roller won't press against the drum. If the rear spring is gone, it provides the electrical contact, so the only actual transfer you'll get will be from physical contact only, totally without the transfer current. =^..^=

On some of our other Mono machines we have had the doc gap clog up some. the old Samsung CLX 3160 used to clog off the toner gap and give lite copy. When I get a chance I will check the Xfer.

If it's OEM toner you won't have much trouble with mottling ... but worth checking. =^..^=

Do they have "Eco-print" turned on for their PC driver or MFD settings?

Back to basics boys....
Clean the optics. It should make a difference.
However light copies may be caused by a number of reasons as mentioned before this post.
