Check the condition of the transfer roller - ideally should be repaced at the same time as Transfer Unit

Your printer most probably has the scanner unit dirty. Unfortunately, this is the type of service that requires a great deal of printer disassembly. My advice is a good Samsung Authorized Service Center. Just ask them to show you their certification.

Getting Full Yield in Brother Printers - Preventing Early Supply Failures


Brother laser printers, fax machines and multifunctions all use a toner reclaim system. That means the used or left over toner (along with paper dust and debri) is recycled into the new toner cartridge supply. There is no waste section for the leftover toner and debri. This design is efficient however their are some short falls that you need to address. The toner cartridge supply is slowly contaminated with debri and dust that will send the cartridge down prematurely if your not using a good quality paper.

In addition, Brother Drum Units (ie DR-400, DR-500, DR-510, etc...) are expensive and suffer from the same premature failure problems. There is a charging brush and transfer roller inside the front top inside of the drum that drags on the drum surface to charge and discharge it properly for toner transfer. If you use poor quality the built up paper dust and debri interferes with this system and ultimately prevents it from working prperly. Here's a photo of a newer drum that failed due to the use of poor paper. Note the paper dust embedded in the transfer roller (top), caught up in the charge brush (center) and actually laying on the drum (bottom).

Here's a closeup of the charge brush so you can see the problem better below.

Below is the damage that bad paper caused. This DR-520 drum pictured is rated for 25,000 pages but due to low quality paper lasted just over 7,000. This was caused by a "Store Brand" paper.

Here below is a photo of the inside of a brother toner cartridge contaminated with paper dust and debri due to la ow quality super store brand paper. Note all the white paper dust in the toner.

To get the full yield from your Brother supplies, simply use GOOD QUALITY PAPER. STAY AWAY FROM STORE BRAND PAPERS as they go out on low price bid rather than to meet a tight quality standard. I would recommend a HP Brand paper as it's an "ALWAYS KNOWN GOOD" paper. The cheapest on the HP branded papers is HP Office and it works well.

Hope this has helped you understand the importance of using good quality paper in your brother machines. If you found this helpful, please rate it with a FIXYA as significant time and effort was used to help you.

Thanks and Happy Printing

Lexmark ms410dn printing poorly


Did you shake the toner cartridge before installing in the printer? Sometimes the toner will clump in the cartridge due to shipping etc., and needs to be shaken to loosen it up.

A toner catridge leaked in my Canon PC921. I cleaned it up and installed a new cartridge, but now my copies are dark on one side, light on the other.


Hello,
on analogue copiers, if You have dark copies, that means that You need to clean optics ( mirrors and lenses - maybe some toner get to them ) or check/clean/replace the fixing film!

Regarding poor copy, clean/vacume/change the transfer roller ( beneath the drum unit - on paper path from drawer/bypass, before fixing unit ).

Hope that helps!

Yellow toner senser not responding


Toner sensor is located in the seat of the toner cartridge, and signal from it is transferred via the drum unit to the contacts on the sides of the drum unit and through them to the printer.
It sometimes happens, that these contacts, either the ones on the sides of the drum unit, or the ones inside the printer, get dirty and have poor electrical contact, giving this kind of message.
Try to reseat the toner cartridge in the drum, clean the contacts and re-insert the drum.

Poor photo printing quality with new color cartridge


Shaking these cartridges does nothing except give you a little exercise. If this is a brand new HP cartridge you are having problems with I would return it to the store you purchased it from. HP brand cartridges should not give you these problems right out of the box. The print defects you are seeing are due to a dried up or clogged print head. If you like you can try hydrating the print head on a water soaked paper towel until the ink starts flowing, but there's a risk you will cross contaminate the colors.

It prints vertical lines where the text is.


check your drum unit. The toner cartridge mounts into the drum which can be permanently charged causing a constant streak to occur.

Solution:
Remove the toner and drum unit. Clean them off with a non-fuzzy non-rough cloth or paper towel. Pay particular attention to where the streaks are in relation to the toner cartridge and drum. If you clean it off and you still get streaks check whether they transfer from the toner or just from the drum.

There may be a way to discharge the drum, otherwise you need a new drum.

Fuser


The fusing unit uses heat and pressure to bond the toner to the paper. Normally poor fusing is evidenced by repeating images or by the print smearing when you rub your fingers across the paper. One fuser roller (the heat roller) is probably aluminum with a teflon coating and the other one (the presure roller) is a type of rubbery material and is often orange.

By your description you mentioned cartridges and that the printer is a full color printer. Is this a laser printer having toner cartridges and imaging units? I just want to make sure you do not have an inkjet printer as they do not use fusers.

The washed out prints you speak of sounds more like a transfer issue such as the transfer belt, transfer charge roller, etc...

Please tell me the brand and model of your printer and I will be more specific.
