Leading The Charge
The primary charge roller springs to life, spinning the adjacent organic photo conductor (OPC) drum, coating it with a negative charge. The electro-photographic process begins at the molecular level, a fraction of our size, and we are merely dust. The drum completes its revolution, slathered with negative energy. It is ready.
The darkness inside the cartridge is broken by the glorious glow of the laser. The beam bounces off a spinning, multi-sided mirror and breaks into countless rays of information, spraying the OPC drum with its knowledge, turning the negative charges positive.
Line-by-line, the laser speaks to the revolving drum, describing an image with the language of charged particles. This part is black, this part is yellow, and this part…yes, this part…is wonderfully magenta. The drum hears the laser’s song and echoes it back, wears it proudly, a positively charged image sitting right on its surface.
Dance Of Toner
The agitator in the hopper spins, and we are roused from our slumber, tossed against one another, suddenly frenzied. The dance has begun. We heat up.
The toner adder roller spins, pulling us in, gathering us on its surface. We’re pulled closer. Closer. Brother Joseph is sucked onto the roller with a gleeful cry. Sister Susan follows him silently. I am next. I am next!
The toner adder roller is the first leg of our journey. Most do not make it to the surface of the adjacent developer roller. Brother Joseph did, only to be knocked back into the hopper a moment later by the doctor blade, which levels the toner on the developer roller to a precise height. Only a precious few — the chosen — make it to the developer roller. These are the fortunate particles that (mostly) end up on the printed image. Oh, to be so lucky one day!
Song Of The Laser
But today is not my day. I fall back into the dark hopper along with so many of my magenta brothers and sisters. We wait. We are not jealous.
The developer roller turns above us. All the spinning and commotion has left the magenta particles on its surface with a negative charge, and when it comes in contact with the positively charged image on the OPC drum, the laws of attraction take over. The magenta toner particles are pulled from the developer roller onto the drum according to the precise instructions left by the laser. A few magenta particles here, several there, and a bunch more that will blend with black, yellow, and blue to form a rainbow of beautiful colors.
Ah, here comes the paper now. We lie still and listen to it pass, first over the magenta drum, then yellow, cyan, and finally black. The four toners sing the song of the laser, and an image is born.
The fuser hums to life, and a sense of excitement and longing fills the hopper. We are not jealous, yet we cannot help but imagine what it’s like to pass between the hot fuser and the pressure roller, becoming one with your chosen paper, melting into yourself and your toner dust brethren, CMYK working together as one, complementing and supporting each other, becoming more than they could ever be alone, sinking into the pulped wood fiber like a feather bed. Fused to paper. Fusion is our collective dream.
Waste Bin Nightmares
A wiper blade cleans any remaining particles off the OPC drum and deposits them into a waste bin. The latent image on the OPC drum surface is erased by the primary charge roller, restored, refreshed, and ready for the laser to sing again. Excess toner not transferred to the OPC drum is scrubbed from the developer roller and returned to hopper. Sister Susan falls back into place. We’ll try again next time, sister. At least you’re back in the hopper, with the chance to fuse another day.
We lie in the dark, waiting patiently for the laser to sing again, for another chance to join something bigger than ourselves, to fuse, to belong, to become part of a bigger picture. But the waste bin… Oh, to have made it to the OPC drum but not to the final product! Such glory…so close, yet snatched away! We dream of fusion, and of the laser’s knowing call…but the waste bin keeps toner trembling at night.
