Kyocera 307ci and 306ci little lines and dots on printed pages

[copyTcat]

Client get little tiny line on the printed/copied pages. something like 1/8 inch all over the page. Usually black but sometimes other colors. Machine has 36,000 copies.
I upgraded firmware, Replaced drum unit and perform calibration, Drum refresh and Developer reset and calibration. After a month client have same issue.
Client using genuine toners drums and developers.
Lately went to client and polished drum cylinder but issue return after 2 weeks. Any idea????

How about a pretty picture for us to look at.
It would help with working out what the cause is.

Is this what you are getting for lines from the black drum?

It is the way it is. You can try to adjust asleep timers but still going to happen.

I've seen that many times ......random toner streaks almost always been the transfer belt. They never seem to last all that long. You might try vacuuming the belt cleaning unit.

Allstar59, i already tried to clean and vacuum the transfer belt but issue is still there. Did kyocera designed this machine soooo bad?
We sold fe of these machine and seems like all having this issue except one. I do belive there is a way to eliminate these specs/lines but no idea how.

Get used to it, they put out a drum that was supposed to fix the problem. I have yet to see a fix

It'll never happen. They're content with people hating their product because they are saving money on a garbage drum unit.

Here is a picture of the lines. Seems like at this point only Black. Drum was replaced but after a month same issue.

Yup, drum. It gets too warm inside the machine causing toner to fuse to the surface of the drum. On smaller machines I've had some success enabling Silent Mode, or shortening up sleep timers to 2 minutes (putting the machine back to sleep immediately after it prints). That will mean waiting for warmup every time you do anything, but it's the only thing that I know to do that works.

blackcat4866 it does make sense that it will be from high temperature (even though the drum was replaced and is 2 months old) but why only the black???
should I reduce the fuser temperature?

Something about proximity to the heat source/fuser. I have seen it on all colors but predominantly on black.

Correct. Black is closest to the fuser, warmest. I have gone so far as to remove ozone filters, check all fan operations, etc, etc. Kyocera is aware of the issue, and may eventually write a firmware to change fan timing. But so far they have not done so for the smaller machines with the same issue.

Reducing the fuser temperature will not help. When running the machine maintains proper internal temperatures. When sitting idle but warmed up, the temperature rises. =^..^=
