Brother HL-2037 Toner Cartridges

Normally our compatibles do also come with instructions but just in case you can see the instructions on the following website that I like to use (manualslib) https://www.manualslib.com/manual/697873/Brother-Hl-2030.html?page=36#manual. The drum unit is attached to the toner cartridge in one unit (that can be separated) so it's this part to follow the instructions.

There shouldn't be any toner spillage when changing a cartridge unless you violently shake the cartridges for some reason and then you may get some kind of spillage. The only other instance of mess might be caused by an already leaking cartridge in the printer but it isn't massively common. We manufacture high-quality toners here in the UK so you will get a fantastic quality printout with our compatibles but they won't be the cheapest around, if you do buy a cheaper product elsewhere you potentially will be buying a lower quality product that might cause issues but at the end of the day, this is completely up to your preference. If you need any more help, let me know!
