Question about Brother MFC-8460N All-In-One Printer

1 Answer

Printout from Brother MFC8460N has vertical faded line across pag

When I print I am getting a vertical line in the center of the page which is faded from the rest of the text. I have recently changed the drum and the toner seems to be fine. The rest of the text of the page prints fine, it is just this line in the center that is lighter than the rest of the page. What can I do?

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.

MFC-9440 CN Laser Printer is producing vertical color line streak


Colored vertical streaks - looks like a transfer belt problem, and it's not user fixable. You may need a new belt unit - you can find it for around US$ 80-120, but you may want to have a technician inspect the unit first, since it could arguably be the drum instead, and you don't want to fork around US$ 100 and replace the wrong part.
You can try showing a printer sample at a print shop; by looking at the streaks it is possible to diagnose drum, fuser or belt problems.
Here you find a much more detailed page, for another printer model, but the issues are mainly the same for most color printers:

First print line print fades away across page,


The page size is off. Try readjusting it in your "printing preferences". Otherwise, if it is new, back to the store for a replacement. It really should not do that.

Try replacing the toner and if it still happens then you have a bad fuser. But im pretty sure its a faulty toner.

Scanner leaves three vertical lines on scanned page


Hello,

A dirty glass base can cause ‘spots’ or blemishes to appear on your final printout. Additionally, if you had some sort of opaque liquid that may have transferred on to the glass base from a previous operation. But the majority of the unwanted vertical lines are generally caused by either a dirty or damaged print roller or faulty LEDs in the Scanner Module.

To separate one from the other you have to check the following:

Do you only see the lines with a Scan operation?
Do your print jobs print fine without any unwanted lines?

If you only see the unwanted lines during a Scan operation, then most likely you have a fault/dirty/obstructed LED module.

If you see the unwanted lines with all print operations (Scan, Print and Copy), then you most likely have a worn out, damaged or dirty Print Roller.

Hope this helps…

Print faded after replacing black cartridge Brother 240C


The print heads don't appreciate being out of ink so the Brother printer has sensors to prevent that but the tape defeated that prevention. Maybe more cleanings or maybe a cartridge with printhead cleaning solution will help. Otherwise, I fear a new printer.
