SOURCE: 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:

HL-5250 report shows fuser and laser life at 0% and PF kit 1 at 12%


The fuser is a separate component to the drum and toner in this printer. It has a much longer life than them but will run out eventually. Sadly a fuser unit is not a commercially available consumable for this printer either. I would recommend contatcing a printer technicain or Brother directly for a quote on replacing this part.

My brother DCP 7055 shows eror replace toner


Some Brother laser printers have separate consumables - the toner cartridge and the drum unit. From time to time you may need to replace only the drum unit and not the toner cartridge.

The error LED lights up, or an error message shows on a flat screen panel, when the drum unit is near the end of its working life. Use the drum unit until you have a print quality problem, then replace the drum unit with a new one.

Says we need a new imaging unit, is there a way to trouble shoot before ordering??


The imaging unit has a CRUM which records usage. It has a life span of approximately 30,000 prints based on an average 5% coverage, so it is possible for one to become end of life at 5,000 prints or less if it has been used for heavy coverage.
Unfortunately the imaging unit is not re-settable but in my experience the Phaser 6125/6130 units are prone to giving print quality issues so it is advisable to replace it if showing end of life.
Hope this helps.

Imaging units for Bizhub C300


There is no setting you can extend the life, however, in the service mode ( utility->meter count-> stop, 0, 0, stop, 0, 1) then press stop, 0, c. There should be a setting in there that you can disable the "image unit life end stop" setting. You will get a message every 5 minutes telling you to change the unit, but your machine won't stop working. Otherwise you can just change the chip in the image unit.

My printer brother hl-2040 drum light is blinking what is the problem


Time for you to replace the laser drum unit in the printer.

the drum units have a life cycle of about 5000 pages and then need to be replaced. Order a new one from Office Depot and simply swap the units.

Cheers,
