400S Black lines at top of copy

Every copy that comes out has some black lines of various shading at the top edge of the paper. There is a new tonor cartridge in. The print itself is fine. Just those strange lines at the top.

    How would these problems be resolved? Purchasing the worn equipment and installing it myself, or is this something a technician would have to do?

Sounds like the drum is worn out. Usually do 60-70K before replacement. Shading more noticeable at top of copy. Could also before worn upper fuser roller.

    Replacing the drum is relatively easy. You lower the transport bed, remove the plastic block below the developing assembly then disengage the developing assembly away from the drum by turning the lever under the developing assembly anti-clockwise. The screw at the front of the drum is then removed and then the drum. Installing the new drum is the reverse of the removal, be careful with the new drum's surface.

Copies are coming out in various shades of black - like its smeared...

Most common cause is a dirty corona wire and or drum. If after cleaning the corona wire and drum the copies are still mostly black and smeared, the drum may be broken. Best of luck.

Paper jam at fixing unit when copying page with black border and complete tx fax function the tx report will comes out

Does the black go all the way to the very edge.ALL copiers have a void area around the edges of the prevent the copy from sticking to the fuser roller, which operates at nearly 400 degrees while copying.The void area can be as much as 6 mm all the way around, that is to say, all 4 edges.without the void area, the copy will always jam at the fuser or fixing unit.Good Luck

Dark edges

It depends... never use a Reman cart in these machines... only use sharp...especially if the machine is under warranty.

Does this happen when,
Using the Doc Feeder
When making copies from the Glass
Or when you print from a computer (assuming you print from a PC)

If you print something and this happens then it is inside the machine
Probably toner or developer dumping...

Take a few pieces of large white paper and cover the entire glass surface... make a copy is the line there? If so see the answer above... if not then close the top and make a copy with no paper on the glass... is that black line there.. If so then your top needs adjustment...

One more test
If you make a copy using the doc feeder, this black line only occurs when making copies with the doc feed, clean the **** glass, and try again...

1-en front door look inside and see if there are black rings around the shiny Drum cylinder, if yes replace drum blade (may have to replace drum also).
2- if lines only come when doing from ADF then lift top and clean the small strip of glass.

Copying spreadsheets

If the lines look like little steps, maybe broken is segments off by about the thickness of a pencil line, try this. Most likely it's the scanner. You can try calabrating it by doing the following. press in order. Menu #1934. You will see a T pop up to the right side of "Ready to Copy". Then press machine status, then scroll until you find maintenance. May be under system settings. When you find maintenance, press enter, then scroll to Shading Adjustment. Or depending on software version, Adjust shading. Place 5 sheets of paper on the glass,, press enter, then when is says "Adjust Shading?" press enter again. Let it print out the sheet. Then try a copy. If that doesn't help, the scanner itself will probably need replacing.
The scanner is the issue. The segments of what is called the CCD are not working properly.
Once you adjust shading, if that doesn't work, the scanner will need to be replaced.

Black lines on copies when run thru fax feeder

There is a thin strip of glass that you will see when you lift the top feeder. There is most likely white-out on it.

When you use the top feeder, it doesn't use the large glass, it only 'rolls' the original document over this small strip of glass.
