Electrographic Process Apparatus TRIZ Cases
- Ink Carrier Switching Control for Expiry-Safe Image Forming
When ink expires during printing, the controller switches to another carrier to maintain image quality and avoid operation stoppage.
- Pressure-Sealing Toner Control for Secure Confidential Printing
Adjusts pressure-sealing toner amount, size, and position by print type to secure confidential materials without excessive adhesion.
- Heating Roller Structure to Prevent Layer Peeling and Rust
A metal heating roller omits the anti-rust layer and uses divided resistance heating to limit peeling, rusting, and warm-up delay.
- Drum Cartridge Coupling for Stable Torque Transmission
A movable drum coupling balances drive and braking forces to keep the photosensitive drum and developing roller rotating consistently.
- Electrophotographic Photosensitive Member With Uniform Aluminum Grain Support
Controlled aluminum grain distribution in the support stabilizes electron flow and suppresses image unevenness during repeated electrophotographic use.
- Developing Cartridge Gear Layout Around a Roller-Side Protrusion
A roller-side protrusion is placed outside gear addendum circles so the coupling, idle gear, and agitator gear rotate without interference.
- Image Forming Speed Adjustment for Consistent Output Quality
Common adjustment timing based on developing drive time keeps toner-related image quality stable across multiple image forming speeds.
