Brother MFC-L8390CDW

We purchased this printer from Centrecom in November 2025 for home office use. Price $529. The printer comes with four small laser cartridges (Black, Cyan, Magenta, Yellow). The printer has only done a total of about 400 pages in its entire life. It has given us constant problems with print quality. Not long after we got the printer, it started printing with a series of black smudges down the page. We contacted Brother support. They required proof of purchase, then required us to take photos of the printer. They then required us to run a series of diagnostic tests and send them the results. They then required us to remove the black cartridge, disassemble it, take photos of the roller and send those to them. There were smudges on the roller, from manufacturing. They told us to clean the roller, which we did to the best of our ability, then reassemble and reinstall it. We did this, but the faults remained. So, they sent us a small replacement black cartridge. This all took about two weeks, so the printer was out of use for that time. We hoped that that would solve the problem. But it hasn't. Because it has reoccurred, this time with the Magenta (Red) cartridge. We contacted Brother again. They said, remove the red cartridge, disassemble it, clean it, reassemble it and reinstall it. We did this to the best of our ability. But, the problem remains. Red dots at regular intervals down the page. It seems that Brother laser cartridges are of very poor quality. Whilst we could use this printer for in-house drafts, we could not use it for anything to send to a client. So, it is virtually useless to us. Apart from downtime, I have spent a total of about 2 hours diagnosing and trying to repair this printer. This is not our job. It should not happen with a new printer. The cost of wasted time runs to $hundreds. We are now considering taking a loss, dumping this printer and buying something more reliable. I do not recommend this printer, or anything with Brother laser cartridges.
