Do they look like smudges? I had the same problem with my Dell. I replaced the drum and it fixed the problem. Its not a cheap solution, but I was able to print pictures again.

My kyocera color copier has blue dots going across the page when I make color copies.


I beleive you listed your question under the wrong model machine. The CS-4035 is a black and white copier and should not be making bluse dots. Verify the model number please.

When I print a color page, there is a multi colored line about a 1/2 inch thick along the left side of the paper. The print quality is good for everything on the page, just this line of swirled colors. ...


Run the Print Quality test. Sounds like one of the color cartridges is bad.
Also run the Disable Cartridge test. That will let you test each cartridge by itself.

Before you do that, open the front door halfway. Now you can see each of the color drums in each cartridge. One of them may have a 1/2" stripe on the drum on the left side.

Unwanted 'dots' on printout


There is a dot somewhere on the drum, remove the drum and toner cartridge from the machine, then remove toner from drum. Look at the shiny roll, you can turn it from the black gear on the side. Once you find the dot use a cue tip dipped into little bit of alcohol and clean it off.

Toner specks along the edge of the page


Rev. Gregory.
Its looks like you have a small pinhole, or divot, on a imaging conponent that is common to all four toner cartridges. Remove the drum unit from the prtr and keeping the green handle close to you pull back the shutter which covers the drum, and look for spots of toner at the either end. If you hold the page with the spots on it, with the leading edge centered and touching the drum, it will give you some idea where the edgeis relative to the end of the drum. If you can't see any corresponding spots on the drum surface.
Put the drum unit back into the prtr and allow the prtr to restart, then switch off and remove drum, this will have turned the drum to a new position, and should show any defects. Only expose the uncovered drum to light for a minute at a time, and avoid touching the surface.
Let me know what you find.
Cheers

Red dots on left of page


You need to measure the distance between two dots (In milimeters if possible). After that I may be able to determine what is causing the problem.

Black spots on my documents Brother HL-1440


Stray dots (on a vertical imaginary line on the page) may not require an expensive drum replacement. In my situation, I simply followed these steps:
(1) Open up the printer, remove the toner-cartridge/drum assembly, and remove the toner cartridge from the drum.
(2) For purposes of reference, place (and center) a sample page of the "offending" output in the bottom of the drum housing, lining up the dots so that the page is turned the way it would have fed through the printer, placing the page generally in front of the shiny green roller surface. Loo, for where any matching black dot or other thing might be sitting on that surface.
(3) Gently roll the green surface's roller with its outside end pegs (without touching the green surface) if and until such a matching dot (or dots) can be found. (Multiple dots might appear along other imaginary verticals on the page, which is to say, additional vertical striping is occurring because there are more instances of "items/dots/garbage" arrayed across the roller on the horizontal, to produce repeat images down the page as the page feeds through the printer.)
(4) Take a Q-tip and very, very, very gently "polish" away the dot(s) you found on the green roller. (I ended up just dabbing the dot I found--which had consistently left a trail of three dots down my pages, in different locations because of the distance the roller traveled relative to the page size--using the absolute least amount moisture to remove it.)
(5) Clean the drum's corona wire by moving the blue plastic slider back and forth, and leave the slider at the far left point.
(6) Reassemble the toner cartridge and the drum and place the assembly back in the printer.

(7) Test.
Worked great for me. Done in around five minutes. No cost, except for the negligible cost of a Q-tip. No time waiting for a new drum to show up, etc.

Top Feeder scanner leaves a line along the copy


This Is good for all "all in one machines"

There is a dot on the 1inch glass, when making a copy or faxing or scanning it makes it form that part of the glass. It shows as a line because the paper is moving as it is being scanned. clean the glass w/ alcohool. Sometimes it is hard to see because the background is black and the dot may be a pen or pencil, but it's there.

try to take the copy and lign it up w the glass and look where the line is you might see it htere.
