Despite following cleaning and maintenance instructions, toners spots appear on printed sheets although using the originally equiped toner and cylinder.
Overall happy with product. Mine is a simple USB cable set up and setting it up was a breeze. The only issue so far happened when it didn't print on command. I went to the printer icon inside my control setting command on my desktop. I opened 'troubleshoot' and the unit worked through and fixed the problem. No other problems since. The only other thing is that I wish the documents I print would come out of the machine a little further, a minor gripe.
I have this printer for about 2 months. So far, it is working good. My previous printers Brother HL-L6200DW (I had 2) is a great nightmare. Both failed after couple months and always printed out dirty pages. I changed the drum unit and clean and not helping. Anyway, I am happy with HL-L5100DN for now.
