1) Many printers have a cleaning feature - a built in process that cleans print heads or toner feeds, transfer belts, etc. In every printer I've seen it's either run when needed from a menu selection on the device, or configurable to run at set intervals (e.g., every few thousand pages).
2) Single-purpose
printers are SO twentieth century. For a couple decades now the Multi-Function Device (MFD) that can scan, fax AND print has nudged aside the simpler print-only models.
SO... design the MFD to run every printed page under a scanner head just after the fuser output. When it detects lines or other defects on output that aren't part of the image stored in its buffer, it could initiate a cleaning sequence on its own.

As long as it comes with the exact opposite as well ie the capacity to insert random glitches and errors to generate visually unpredictable abberations as printed outcomes. |

You work for the company that holds the service contract? |

And there was me thinking this was a self-MFDing idea. |

But it certainly will be if/when someone points out an available printer with this feature. |

Why would they do this when they can just make it self-clean more than necessary, using up incredibly profitable ink? |

If you combined a roomba with a 3d printer, you could make a self- printing cleaner. |

An inkjet addon to the shower nozzle in the bathroom could be a cleaning self-printer |

A printer with a mini vacuum attachment to keep the shelving on which it sits next to your computer dust-free would be a shelf-cleaning printer |
|

My antique printer has a pretty powerful cooling fan so all that would be needed would be a mount to hold the printer at an appropriate level to blow the dust off the shelf. |

I miss the days of watching the big pen plotters scribble back and forth in an x-y grid at silly speeds. |

A stick with a camera on it and a feather-duster could be a print-cleaning selfie. |

Revision: Instead of relying on comparison between user-submitted jobs and output, the printer could have some reference images built in and scan its own test page at predefined intervals. This might give a more consistent result and also answer [Voice]'s Mar 10th concern that it wouldn't waste enough ink or toner to be profitable to the manufacturers. |
