One motor drives document conveyance and calibration, reducing pauses and document movement during duplex image reading.

A confined hot-air roller and non-stick intermediate film fix toner and add finishes while preventing media overheating.

This image forming case relocates white reference plates onto the reading glass to avoid sheet rubbing, staining, and paper jams.

Axial charge-generation layer variation offsets coating effects in polyarylate transport layers for uniform charging.

This case adjusts thermocompression heat using sheet temperature to maintain adhesive strength while reducing energy waste.

Measure sheet resistance while neutralizing charge before user contact.

This case uses a rotatable upper unit to expose sheet guides and static elimination components, simplifying jam removal and cleaning.

This developing device uses magnetic pole geometry and peeling control to limit developer mixing, clogging, and stripe defects.

This developing device uses toner-polarity biasing on a conductive roller to contain toner without adding pressure-raising shields.

A toner cartridge chip module uses two contact ends per terminal to maintain reading-head connection despite conductive-strip deformation.

A stationary cleaning sheet uses hard roughening particles to remove toner residue and preserve charging quality.

This case separates toner-cartridge support from housing movement, while a spaced seal limits leakage without obstructing toner flow.

Retry-based memory access keeps printing through transient cartridge communication failures.

A non-contact reflector redirects heat, while a graphene or graphite equalizer reduces temperature variation and fine-particle generation.

A front-opening cover exposes a work surface and support unit, reducing effort when positioning large media or jigs.

A support-plate extension and push switch identify compatibility while reducing frame complexity, size, and fixing-device cost.

A reverse conveyance path and roller-speed control reduce discharge defects while maintaining toner transfer contact on thick paper.

This case uses resin-frame guides and a movable separation shaft to align the developing roller with the photosensitive drum.

Transfer-current feedback controls exposed potential, stabilizing image quality without a separate surface potentiometer.

A curved passage and timed jam-detection pause improve transparent-sheet conveyance without false clog determinations.

An opening cover exposes relay connectors while their offset layout avoids conveyance-unit paths during attachment and removal.

Scratches and oxidation raise chip contact impedance; usage-based transmission rates improve recognition and printing time.

A supporting portion separates vertical lifting from horizontal guidance to reduce mounting force and connect developer openings smoothly.

Stored timing data helps identify the faulty motor or load in an image forming apparatus, reducing diagnostic replacement work.

This case shows how a damper cushions a moving sheet-processing unit before braking, reducing impact and preventing frame collisions.

This case uses mirrors with 93% reflectance and 96% uniformity at 45° to reduce optical losses and prevent dark or inconsistent images.

A downstream reader measures fixed adjustment patterns and sheet length, enabling position and size compensation for accurate duplex registration.

Variable-speed communication helps consumable chips overcome contact oxidation.

A slow idle rotation changes charger and cleaner relative positions, limiting residue adhesion and stabilizing image quality.

This case uses a harder slide aid over a vibration isolator to maintain smooth pressure switching and reduce collision noise.

A contact member measures wound-web diameter through resistance feedback, enabling accurate winding control and longer web life.

A centrifugal brake and damper slow heavy draw-out units, absorbing impact and protecting the brake from excessive loads.
