Remove the fuser. The toner still won't disappear by itself, but the more the printout is handled, the less you'll be able to read it. |

You could also print on black paper, but you wouldn't get the same effect. |

Where I work we remanufacture old toner cartridges for sale. The only way I could think to do it would be to change the formula of the Toner (ie, remove a lot of the phosphates) so that the Toner would be very sensitive to light and fade. I don't know how long it would take. Maybe about 6 months to a year. That's how the invisible inks work anyway. |

The KGB had a really good disappearing ink for pens and such. If conditions were good, it would slowly fade from black to invisible in about a week. Possibly it could be adapted to work for toner too. |

At this point Mr Thundercleese fell into time vortex,

Or did he just ‘disappear’? |
|
| |
No, he was definitely seen being assisted into a black helicopter by two burly men wearing sunglasses. |

//by two burly men// You never see anything else described
as "burly", do you? I mean, you don't get burly furniture; an
overfilled sandwich is never burly; it's always and only "men". |

A service that swaps your, your boss's, and your SO's toner with this upon the consumption of more than a set amount of alcohol or Ambien. |
