Black lines vertical and horizontal on printed pages in addition to the persistant error message to change the drum I just found out how to re-set that. Does this sound like the fuser is going?

If the black lines are combination of thin and thick lines you really need to replace the drum instead of just resetting it.

Just examine the drum if there are scratches. (",)

Tip

When u print if u r getting the Horizontal or vertical line then follow these...


If the print is a dismal gray rather than a sharp black, you are probably almost out of toner. This can manifest itself evenly across the entire page or in splotches or stripes, depending on the printer.
Sometimes you can wring a little bit more out of a toner cartridge by taking it out and gently shaking it from side to side (never up and down, as toner can spill out). You can also try turning up the printer’s contrast adjustment, if it has such a knob (usually on the back side if it exists). Faded print can also result from a dirty corona wire, because a dirty wire inhibits a full electrical charge from being passed.
If the printouts are consistently varied in density, and you have to frequently remove the toner cartridge and shake it to redistribute the toner inside it, make sure the printer is sitting on an even, flat surface.
Horizontal black lines
A horizontal black line on the printout is probably the result of a dirty or damaged roller. There are lots of rollers in the printer, and you can use the space between the lines on the page to determine which roller is causing the problem. Measure the distance between the errant black lines on the page and then use Table A to determine which part might be causing the problem. Table A
Distance between lines
Faulty part
0.5”
Registration assembly
1.5”
Upper registration roller
1.75”
Lower registration roller
2.0”
Toner cartridge developer roller
2.56”
Lower fusing assembly roller
3.16”
Upper fusing assembly roller
3.75”
Toner cartridge photo drum
Regularly spaced splotches
If there are evenly spaced black spots but they don’t extend all the way across the page, the problem is probably a scratch or flaw in the drum or a build-up of toner on the fusing roller. If the spots are less than three inches apart vertically, it’s probably the drum, because the drum has a larger diameter than the fusing roller.
Vertical black line on edge of page
This can indicate an almost empty or faulty toner cartridge or (less frequently) some spilled toner inside the printer.

If the whole page is covered by these black lines, then you have to replace the developer unit K..
If there is (for example) one black line that is been repeated in page three times (vertical) then you have to replace the drum unit. The drum units are all the same, so you can test by change two drums between them.

My samsung ML 2510 prints a black streak on each plus a watermark from previous page


If your paper setting are set corectly (normal paper) and you are getting a "ghost image" from the previous page, most likley the fuser is the problem. On rare occasions, the drum unit could be the culpret (Black lines) down the sides of the page as you indicated.
You may have 2 problems.

I would change the toner drum 1st. If the black lines go away ,yet the ghost image continues, then change the fuser as well.

This solution is unconventional but it worked for me. The black roller on my MFC had irregularities on it and was creating horrible printouts. I pulled out the drum and cartridge and cleaned the large black roller. I used furniture polish to make the roller very smooth. Now it prints really nice.

Black lines when printing brother 9320cw


Vertical black lines means the printer requires maintenance or a new drum. Horizontal lines means a circuit board with problems.

I do recommend maintenance every 6 months at least.

Problem for print by photo copier


sounds like the charge grid is not set properly in the drum unit..did you et up the drum unit properly and run the new dev and drum set up..if youy are getting black the charge is not working correct as the charge of the drum help to keep the toner from adhering to the drum surface when copying .. I would take the drum chrge unit out again and check it is set in the right way when you put it back on also check the contacts arent put out of line.

Printer prints white thick blank lines


1- black lines are from the drum: it has burnt out on that particular spot and rotates

2- the white horizontal gap space if it is not you skipping space is also from the drum

3-the white Vertical is most likely from the developper (unit that has the toner and is against the drum, look at the roller it should be solid black, maybe there is something on it : hair paper etc....

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.
