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.

Printed pages are smeared with black


Sounds like a bad toner, or possibly the scanner is dirty. If you look where it pulls the paper through it can have a small speck, but since its on the scanner tself it will put black lines all the way down the paper.
If its larger and smeared the Toner itself is probably bad and you need a new Toner Kit, should come with new rollers and a new cartridge as well.

Black streaks on paper on samsung ml 2150 laser printer


Could you describe these marks for us please.

Are they small specks or blotches? Bad Toner Cartridge

Are they lines:
Horizontal - Transfer Roller or Charge Roller
Vertical - Bad Toner OR Bad Fuser.

Note: A bad toner cartridge can render all of the parts listed here useless. Check for build up or lines on the cartridge reflective drum. Avoid light, as with film.

If they are a mix of both, the device needs to be cleaned with a can of compressed air. You must remove the cartridge, paper tray(s, and fuser to create clear path.

Hp 4550 vertical line down center of page


From the service manual:


Vertical lines or streaks
 Check for a leak where light might be entering the printer.
 Check for circumferential scars on the photosensitive drum. If scars are present, replace the
drum cartridge if the line goes through all colors.
 Check for circumferential scars on the upper fusing roller. If scars are present, replace the upper
fusing roller if the line goes through all colors.
 Remove the imaging drum and inspect main charger or imaging drum for a contaminant, such as
a fiber, if the line goes through all colors.
CAUTION Do not expose the imaging drum to light for more than 15 seconds. The drum is light sensitive, and
exposure to light can cause permanent damage.
Vertical black lines
 The toner cartridge is defective.
 The toner cartridge is not seated properly.
 The fuser entrance is dirty.
 The fuser has scratches on it.
 This might be a repetitive defect. If so, the lines will repeat at a consistent interval down the page.
 The printer needs to be cleaned.
 There is a problem in the heating element.
Vertical white lines
 If white lines or streaks appear only in the black areas of the printed media, print several
configuration pages to clear the anomaly. If this does not clear the problem, check the sleeve
surface to confirm the defect, then replace the black toner cartridge.
 If white lines appear only in a particular color, try printing several configuration pages to clear the
error. If the error does not clear, check the sleeve surface to confirm the defect, then replace the
defective toner cartridge.
 There is a lack of toner or the toner cartridge is faulty.
 There is dirt in the laser path.
 The fuser is defective.
 A mirror in the laser scanner is dirty.

Did you try cleaning the lense? You'll have to pull all the toners and open the little door below and wipe with a clean lint free cloth in ONE direction.
