Question about Brother DCP-7020 All-In-One Laser Printer

1 Answer

Black vertical line on prints and copies. 20 blank copies will eliminate line, but as soon as I print something that draws on the toner the line is back again. Have replaced drum and toner without any change in print quality. Have cleaned the machine over and over. Have looked in the back of the printer where I can remove jams and one of the rollers has a black line running around it. Have tried to clean off but nothing comes off. Please help.

It appears that the Teflon is worn off of the roller. You will have to have the FUSER replaced.

White "lines" on copies and prints ? - side to side every 1.5 inches ( approx) is blank ( no toner) creating "lines".


the drum is light sensitive and if one side was exposed to sunlight for as little as 20 seconds could have that effect , it is at best a shot in the dark (no pun intended)

Our copies are streaky like the drum is not clean.... help! There is black streaks on the top of all of our copies on our canon imagerunner 3300.


A) Black Streaks, Shadows, And Ghosting
Adjust the printer's lightness/darkness setting to 2-3 different variables and see if problem disappears. Look at the fusing assembly - is the roller torn or does it have any black buildup? Use caution!!! It gets HOT!

Try another toner also.

HP 2600N PRINTS A BLACK LINE VERTICALLY ACROSS THE PAGE (FROM TOP TO BOTTOM) RIGHT IN THE MIDDLE EVERYTIME YOU PRINT SOMETHING . WHAT COULD THIS BE? I HAVE CLEANED EVERY DRUM, THE FILM ETC AND IT KEEPS...


You either have a defective black toner, a bad fuser or transfer belt. From my experence it is usually a bad toner cartridge. After you print a couple of pages, pull the black toner and see if there is anything on the drum. If there is try shaking the toner, sometimes toner does like dirt and clogs up. If you still have problem you will have to try another toner. I know that is not cheep, but I don't know any other way.

Lanier 5622 Prints vertical lines


You could remove the color and black&white drum units and check from below the units to visually observe lines on all the 4 drums. If so, you have to change the drum unit/units. Drums occassionally get damaged before life this way due to solid toner particles inside the toner bottle.Always "shake the toners very well" before replacement, and if you print rarely, then remove the toners and do the shaking to prevent clogging due to inactivity.

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....

Toner issue getting to drum - use gen toner cart.

or Drum blade stuffed (lines are down page fro top to bottom- replace drum assy

Drum has been exposed to light faint or blank across copies repeated 4 times down page - replace drum assy

or upper fuser roller stuffed, down page, smudgy print -  replace fuser

LSU(laser) or boards rarely cause issues
