Question about Brother HL 5140 Laser Printer

1 Answer

Bad Print Quality

We replaced our drum unit because the light was flashing, and since we've replaced it, the quality of the print is horrible.  It is very dark with black lines / streaks running all throughout the print.

Re: Bad Print Quality

Are you using recycled toners, as these have a habit of spilling toner out? Take the toner unit out of the drum and look at the green roller in the drum to see if that has the toner marks on it.
Don't hold this unit in the light too long as it can damage it.

Not printing completely, orange 'drum' light flashing. Model HL2040

This means you need to replace the drum unit but if the print quality is ok you can reset the counter and avoid outlaying the money for a new one.
Simply open the front door and hold down the button until the lights flash, close the door and the drum counter is reset.

Drum light blinking

The light blinking means it's almost used up, when it comes on solid it will stop printing. If your prints still look good you can open the front door and hold the go button til all lights flash, and it will think it's a new drum. You can replace then when print quality gets bad.

Press the cover release button and then open the front cover of the printer.

Press and hold down Go button until all 4 LEDs are lit. Once all 4 LEDs are lit, release the Go button.

Close the front cover.
Make sure that the Drum LED is now off.

Drum Light flashing

You can continue to use the printer, but when print quality deteriorates, replace drum. Light will continue to flash until you do so.

Bad photo quality after changing drum

your laser printer
1) print color quality is now distorted that means print skew (technician called)
2) print tint means the print color not enough density,
3) print mottle means print dirty
you may try
1) print distorted--- find out the skew adjustment from your printer manu, it is adjust the image before transfer to the drum.
2) print skew could be happened when the drum replace install not very accurate, so install it more carefully.
3) print tint---you may increase print density from the manu, not fix,
4) print tint---the toner caridge near life cycle or using the less compatible toner. so you have change the quality toner or cartridge (if near life cycle) to improve quality photo print
5)print mottle---toner quality ? or cartridge near life cycle also cause print dirty paper,

hello babu,
the problem is not with the printer, problem is with your general knowledge, to print on cd/dvd surface means you have to stick the sticker (cd label sticker) on the cd, then put the cd on the printer to print.
bye bye
hope u will soon understand......
