I purchased the Brother HL-6050DN series printer at just under £450, for everyday use in the office. The intention being that by spending more money on a high quality laser printer, I was hoping that it would withstand high volume printing over a long period of time.
On average I would guess I print around 100 A4 pages a day. The paper tray is of a good size, meaning you are not forever filling it up! I would estimate that the paper tray hold around a whole ream of paper.
I do find the toner cartridge has to be replaced quite regularly, but I do print quite a number of pages daily. The only option is to print in black ink no colour, but that suits my needs perfectly.
The quality of the printed documents is good, with them printing very fast as it's a laser model.
The printer also has a drum unit which does have to be replaced over the course of time, however in the time I have had the printer it has only been replaced once or twice. The only problem with replacing the drum unit is that you must ensure you remember to re-set this through the digital display so that the counter inside the printer registers the new drum. If you forget to do this the printer will continually flash with a message saying that the drum unit requires replacing when it sometimes doesn't.
The printer has a digital display where it will also warn you when the printer cartridge is getting low. It will also advise if there is a paper jam or if you have a more serious problem, which at that point advises for you to contact an engineer.
A major feature in my opinion, with this printer is the duplex feature, which is great for saving paper printing on both sides. The speed that it prints in duplex is exactly the same as when printing one sided, it very quickly feeds the paper back inside the printer to print the other side.
Recently I have found that the printer does jam the paper quite often which I am unsure why, but this could just be due to general wear and tear.
In my opinion, it is a great printer however only purchase if you are in an office environment where you are printing high volumes due to it's cost. The printer cartridges and drum unit are also fairly expensive when they need replacing, at around £50-60 for the toner and £80-100 for the drum unit, for that reason I award 4 stars.
