Force MFC-8890DW to Keep Printing

Today we will be learning how to use a Magical Toner-Generating Device (MTGD) to enable your Brother black-and-white laser printer (specifically, model MFC-8890DW) to print even when it is out of toner! We’ll use this Weird Trick Invented by a Random Guy on the Internet! Printer Manufacturers Hate Him! But that’s okay, because The Feeling is Mutual!

(Full disclosure: I did not invent this trick. But I like to pretend that I did, because it makes me feel smarter and more nefarious.)

My Brother MFC-8890DW has been complaining of low toner for a while now, but I have been ignoring it because there is no appreciable difference in the documents it is printing. Then last week, right after printing a perfectly crisp page of text, the printer announced that I needed to Replace Toner and petulantly refused to print me more documents until I met its extortionate demands. However, based on my past experience with laser printers, I am under no illusions that they suddenly go from “prints just fine” to “completely out of toner”, and based on my experience with printer manufacturers, I am completely willing to believe that they will disable your printer and hold it hostage as a sort of scheme to force you into buying more printer supplies.

The general approach here is going to be to install a Magical Toner-Generating Device (MTGD). It works by absorbing the lies spewed forth by printer manufacturers and condensing them into a black powdery substances which can then be applied to paper the same as regular toner. Quality may vary, but so far I have found the results to be satisfactory. The device itself looks like this:


Thus, we come to the nefarious directions for circumventing the printer’s extortion scheme. I like to think of this as the hostage (that’s me) escaping from the extortionist (that’s the printer), subduing it (after a brief scuffle), blindfolding it, putting it on the edge of a cliff, and holding a cattle prod to its back while shouting “Print, curse you! PRINT!” This process may violate the DMCA and/or other local laws, it may void your warranty, and it may result in an immense sensation of personal satisfaction. Use at your own risk.

  1. Open the front cover.
  2. Pull out the toner cartridge.
  3. On the right side of the cartridge, locate the little clear, round “observation window”.
  4. Apply the MTGD. That is to say, cover this window with black electrical tape.
  5. Put the cartridge back in and close the cover.

Here are two helpful illustrations of this complex technical procedure:

Toner cartridge: Before!

Toner cartridge: After!

In my case, this operation convinced the printer to merrily continue on its way, printing completely acceptable pages. (Since the printer claimed the toner was empty, and since we know a printer would never lie about its toner levels, I like to think it’s now using magic toner.)

I need to go do something else now, as I just heard a strange noise and the printer seems to have shifted position overnight, inching a little closer to my office chair. This won’t take long.
