I ran the self cleaning for the black cartridge a couple of times, but still no black would print. I had replaced my Brother MFC-5920DW's black cartridge after the printer alerted me that the black ink was running low however, after replacing the black cartridge, the printer would only print color, no black.

Unplug and replug any connectors that are related to this system - or just be thorough and replug every connector in the entire machine. If you're getting no black printing whatsoever and the problem is none of the above, take the device apart and verify all the connections. Something to check.Įach print head has a data cable going to it and sometimes they break or get unplugged. In an extreme case, I've used a small drill bit to create my own vent hole that I knew for certain was open.Īccording to this blog, there is an ink-level sensor on your device that might be malfunctioning or otherwise be in need of bypassing. On some models there are multiple holes being covered and it's easy to only pull the cover off of the first one or two. It's messy but usually cleans out a clogged head.įirst off, make sure that the little piece of plastic covering the vent hole is completely removed. I then use Qtips with rubbing alcohol to clean all of the remaining ink-paths that exist in the printer.
