Shake Your Toner Cartridge

In a story entirely unrelated to the Harlem Shake I was recently almost out of toner on an unbranded cartridge for my Dell 1700n laser printer. Without the time or the resources immediately available to acquire a replacement I opted to just take the cart out, shake it back and forth for ~10 seconds and reinsert it. Voila! >300 prints later and it's still going strong, strong enough that you'd never know it was low on toner. I'm sure it'll still need replacing soon, but as a temporary stopgap I couldn't be happier.
