    I have a Laserwriter Select 360 that I use at work for document printing. It's part of my small, in-office local talk network that includes a couple of G3s, a Quadra, and a 512Ke.

    In any case, when I first was given the printer it would smear toner all over the place. As best as I could tell, the drum was shot as I would occasionally(carefully) clean the drum, and rotating it would cause it to pick up toner. I went through the whole routine of cleaning the contacts and other things, but still couldn't get anything. The problem was terrible, and I'd get toner smears on both the front in the back.

    I now have a new(or, more correctly, remanufactured) cartridge in its place. All of the excess toner on the printed page went away, with the exception of the fact that I'm now getting a series of "dots" down the page as show below

    The "dots" look to repeat at a distance about equal to the circumference of the drum, although the drum remains perfectly clean.

    The old cartridge left toner all over the place, and I've cleaned it up as best as I could. I'm wondering if-perhaps-there's a roller somewhere in between the tray and the fuser that's transferring these, although if that were the case I'd think that it would have disappeared by now(I've printed probably 50-60 pages since replacing the cartridge). The "dots" are firmly on the paper, so I'm assuming that they are getting transferred before the fuser-or perhaps in it. As best as I can tell, the fuser is located directly before the output tray.

    Any thoughts on what I might be able to do to fix this? If it's possible to do without damaging, I'm wondering if I can take the fuser apart and give it a thorough cleaning-or perhaps the entire printer needs that.

    I've been through the service manual, but it seems as though most solutions are "replace toner cartridge" followed by "replace printer."

    If you can provide an EXACT measurement from the top of a dot to the top of the next dot in millimeters, I may be able to tell you which roller it is.

    EDIT: 95mm would be the Toner Cart, 72mm would be the fuser assembly.

    38mm is the number I'm getting. It's consistent across several printed pages and across the dots on the same page.

    That being so, you're looking for a roller of 12mm diameter.

    I don't have diameters for all the rollers in the FujiXerox engine that it uses (other Apple printers are Canon engines and usually have all the measurements noted).

    At that diameter, I'm thinking the primary charge roller which is the smaller roller inside the toner cartridge. :(

    The primary charge roller is in direct contact with the drum.

    Just thought I'd follow up on this after a long term.

    Apparently the old(bad) toner cartridge REALLY made a mess everywhere. I use this printer infrequently(probably once a week) but noticed about a month and a half ago that the "dots" were starting to get a lot less intense. They are now completely gone.

    Thanks again for the help on this.

    Old post I know but the marks are caused by a blade within the drum. As I understand it these are rubber type of thing and they are probably recycled. I had brand new toner do the same yet some older toner carts were fine. I think the rubber goes hard and doesn't clean the drum properly.
