Still in warranty or less than 3 years old? I saw the Reddit post on this issue, might still be worth asking, they may have developed a hardware of software fix, and if not they may allow you to switch model.

That noise is the heads being cleaned, which needs to happen on all inkjet printers. It may be that your one was simply broken. I bet if you call Brother and ask for some advice they will help you.

Called brother about this and talked through the issues raised by Rossmann, they convinced me enough to buy 3 printers from them this month.

Which printer and why? I just bought three L8690CDW Colour laser printers for me and my family after calling Brother who were happy to talk me thought my concerns, they informed me that this model does not have chipped cartridges so it’s ineligible for their cartridge subscription program and they also can’t tell if the cartridge is genuine or not. They don’t care if you use 3rd party toner.
