Abstract
In an example implementation, a method of cleaning a silicon photoconductor includes contacting the silicon photoconductor with a base-peroxide solution, rinsing the silicon photoconductor with a liquid, and heating the silicon photoconductor to evaporate the liquid.
Claims18
A method of cleaning a silicon photoconductor comprising:
- contacting the silicon photoconductor with a base-peroxide solution;
- rinsing the silicon photoconductor with a liquid;
- and
- heating the silicon photoconductor to evaporate the liquid,
- wherein heating the silicon photoconductor comprises engaging the silicon photoconductor with a heated print blanket to bring the silicon photoconductor to an operating temperature of the heated print blanket.
2 more elements
A system for cleaning a silicon photoconductor comprising:
- an electrophotographic printing device;
- a silicon photoconductor removable from the electrophotographic printing device;
- a cleaning station comprising a base-peroxide solution and a rinsing solution, the cleaning station to receive the silicon photoconductor, contact the photoconductor with the base-peroxide solution, and rinse the photoconductor with the rinsing solution;
- and
- a photoconductor heating mechanism to heat the photoconductor to evaporate the rinsing solution from the photoconductor,
- wherein the system is adapted to automatically transfer the silicon photoconductor from the electrophotographic printing device to the cleaning station, clean the silicon photoconductor by contacting the silicon photoconductor with the base-peroxide solution and rinsing it with the rinsing solution, and transfer the silicon photoconductor from the cleaning station back to the electrophotographic printing device.
3 more elements
A non-transitory machine-readable storage medium storing instructions that when executed by a processor of a printing device, cause the printing device to:
- receive a silicon photoconductor that is cleaned and rinsed by a cleaning solution and a rinsing solution, respectively;
- in response to receiving the silicon photoconductor, performing heat cycling to evaporate remaining rinsing solution from the silicon photoconductor.
