Necessary Supply; Replacement Can be Delayed,
This review is from: Brother Black Toner Cartridge (TN-350) (Office Product)
I had this rushed a few weeks ago because my HL-2070N kept refusing to operate every ~20 pages due to a low toner error. However, unlike on most laser printers, the print quality was still perfect at this point -- no streaking or blank spots. The problem is that the printer senses that it is nearing the end of the cartridge and refuses to continue, even with toner remaining.
Based on some web searching, it seems that the sensor is based on shining light into a ~1/4" hole on the side that goes through the entire length of the cartridge. Covering this hole with black electrician's tape has let me print a few hundred more pages, with no problems so far and still no sign that the toner is running out.
So, it's good to have a spare on hand, but it hasn't yet been necessary to install it.

Wow, thanks! I live on a military base in South Korea, and purchased this printer for myself last summer. My toner "ran out" about three months ago, and like you, the print quality was still perfect. I've been unable to find this toner at our local exchange, and have been loathe to shell out nearly half the price of the printer for a new toner cartridge. Now I'll get my money's worth from each cartridge. I used some electrical tape myself, and am back in business. :D

Thanks! I knew there had to be a way because in my experience, when a toner cartridge is really running out, the prints will start looking faded. But, my 'toner' light went on before the print quality worsened at all. The tape over the optical sensor on the right side of the toner cartridge did the trick!

Be careful, folks! This does not work with the DCP 7020.
It went into run away printing mode and ended up jamming the printer badly. After two times of trying it, with the same result, I've ordered another cartridge! (Nov. 29, 2009)

I print maybe 1-2 pages a month (usually just Groupons), and I purchased this printer for $40. Tried the optic block trick and it worked! Lets see how many more pages it prints out. Thanks!

Yep, I've since gotten a newer Brother HL-2170W printer that takes the TN-360 cartridges and this trick no longer works at all. Oh well.

Another A+ for this tape trick. I print 100 pages a year at most and was dreading getting a new cartridge, but I've taped it up and it now runs perfectly.
When will printer makers get a grip and just give us what we want without crazy techniques like embedded microchips and unnecessary laser techniques to try and extract every ounce of cash out of our wallet for their ink as early as possible.
