Electrographic Process TRIZ Cases

A cleaning device uses a catcher and storage portion to prevent toner and lubricant accumulation on the cleaning blade.

A priming agent mixed with powder coats the lubricant applicator to spread a thin lubricant layer on the imaging surface.

A bushing assembly with a groove provides precise axial and rotational alignment for developer roll shafts in electrophotographic devices.

A terminal contact structure uses a guide member to separate insertion and contact directions, preventing abrasion during photoconductor unit maintenance.

Nesting screws in a lower recess prevents accidental user removal while maintaining stable attachment of the main body and optional device.

A drawer unit locking mechanism uses a rotating shaft and pushing wall to disengage the lock during insertion.

A supporting member moves a cartridge drawer between inside and outside positions to enable stable component replacement.

A photosensitive cartridge guide member directs light orthogonally to neutralize drum charge.

A developing cartridge pivots on a third axis to align with the photosensitive body during installation.

An integrated rigid-body plate suspends the scanning unit to shorten the distance to the photosensitive drum and reduce apparatus height.

Intermediary protruding portions transmit pressing force to eliminate vibration-induced instability and ensure consistent contact pressure.

A release lever and latching chip mechanism prevents damage during maintenance.
