Laser printer care 101:
Step 1; Google the service manual for your machine and download it if you can find it. - Brother service manuals are not known to be readily available online, but if you call a service center and talk with a tech, they may just email you one for your machine. This will help you thru times of printer trouble more than anything else in my experience.
The Brother consumables (toner& developer section, image drum, fusing section, transfer belt(if color)) are not designed with longevity in mind when compared to most other brands, so be prepared to see a message to replace something eventually. With the exception of toner, these messages are set to display when the print engine hits a certain amount of prints (ie;12,000 prints for a developer section), and can usually be reset back to zero in the service mode. I recommend doing this and only replace the consumables when image quality starts to degrade.
Over time loose toner, paper dust, and common dust in the machine can contribute to a wide array of problems ranging from print quality issues to paper jams and overheating issues. Keep a can of air handy and blow out as much of the machine's interior as possible whenever you change the toner. If you notice a large amount of loose toner inside, it's best to vacuum it out to avoid blowing toner onto the laser scan unit lenses. Because laser printers use static bias charges to move toner onto the paper, keeping the machine in a clean, regulated environment will greatly prolong the life of your machine.
Do not cover the printer with any sort of plastic covering when it is on or in sleep mode. The fuser section can produce about 225f degrees and anything that traps heat can be very detrimental to the machine, and possibly dangerous. The machine's fusing section produces just the right amount of heat to bond the toner to the paper based on the paper type. Thick paper takes more heat out of the fusing section than plain paper does so to avoid any toner bonding or smearing issues when printing on heavier paper, remember to set the paper type in the print driver to match what you are printing on, so thicker paper can be run thru the fuser section slower, and allow the fuser to maintain it's heat and properly bond the toner.
Do not run any plastic or wax impregnated paper thru a laser printer - it may melt in the fusing section. Only use laser printer compatible paper.
Most jams are not actual jams, but what is known as a paper late jam error. This is where the paper pick-up rollers become dirty, dusty, worn smooth from use, and are no longer able to get the paper to the 1st paper sensor with in a certain amount of time, so the machine thinks it's jammed when its actually not. Cleaning the pick-up, retard, path rollers, the ADF feed & path rollers with a mild cleaner such as 409 or similar and a clean lint free cloth will remedy this.
Cleaning the scanner's flat glass and slit glass will prevent image quality issues. While using the ADF (Auto document feeder) to make copies, you may notice vertical black streaks that run the entire length of the copy (this will not show on prints or internal reposts). This is due to contamination on the slit glass, which can be cleaned with any glass cleaner and a lint free cloth.
Do not pull jammed sheets of paper out in the direction they came from( in reverse). Doing so may bend the picker-fingers into the fuser surface and damage it or break the paper sensor flags. Remove all of the consumables (toner/developer section, image drum) open the back panel and release the pressure tabs of the fuser and pull out any jammed paper in the direction it's supposed to go.
Also, If you plan on maintaining your warranty, refrain from using any 3rd party toners(non OEM), as it may void the warranty (read your warranty and look for this). Non OEM toners are not precisely formulated to match the brand manufacturer's specific toner formula (toner is basically magnetite, pigment, and plasticizer), and can cause all kinds of issues for the machine ranging from plugged toner supply ducts, bias transfer issues, fusing issues, which all result in crappy print quality. The non OEM toners will all say they are 100% compatible but it's nothing more than advertising to get you to buy it. NOTE:---I have a client with a Kyocera FS-C2126+ MFP which cost him $1,600 last year and its worth approximately $0.00 today because he insisted on using 3rd party toners, which caused all kinds of image quality issues and the non OEM toner cartridges didn't precisely key with the driver gear properly which eventually broke the toner interlock and drive mechanism (very expensive to replace). Per his warranty, I had to notify him in writing that he had voided it and Kyocera would not provide any repair or parts free of charge - He was 100% responsible for the incurred costs at full rate. SAD!!
And lastly, As a Courtesy to Others, Please Clean the Scan Glass after making Butt Copies. Thank-you, Management
Enjoy yer new printer and DONT YOU DARE ATTEMPT TO OVERCLOCK IT :) - JK!
Sorry to be a windbag, but this mumbo-jumbo will save you money and anguish in the future if you apply it now. I know this from experience - I'm a certified Kyocera Service Technician (copier repair dude), and deal with this stuff all day long.
