A light-shielding layout hides member gaps and boundary lines from the capture area, improving document reading precision for large sheets.

Siloxane-modified resin surfaces and siloxane oil improve fuser sliding, suppress tribocharging, and reduce wrinkling and electrostatic offset.

Pre-transport height detection stops oversized objects before they reach the transfer unit, reducing collision damage and alerting workers.

Inserted trigger images let an image forming device detect transfer quality changes and start color correction only when needed.

Print status feedback triggers collection forms and pickup requests at the right time, improving waste paper recovery and recycling efficiency.

A chip contact and positioning layout prevents terminal collision and debris buildup, keeping printer cartridge communication stable.

By varying sheet discharge distance between pages or jobs, this case helps printers keep outputs separated without slowing continuous printing.

Height sensing and dual suction belts stabilize elongated sheet transport between transfer and fixing sections, reducing buckling and loop instability.

A detachable seal holder in a toner shutter unit keeps sealing reliable during use while making seal removal and replacement easier.

A moving supporting unit holds the light-emitting unit during maintenance, improving stability and reducing manual support steps.

Jam detection triggers early pressure release in thermal sheet binding, helping users clear stuck sheets without tears or wrinkles.

A controlled resistivity path between fixing and pressurizing rollers removes charge without extra grounding parts, reducing electrostatic offset.

Door-state feedback stops sheet-loosening air flow during jam clearance, cutting wasteful power use in image forming feeders.

Thermal expansion sensing aligns fixing and downstream nip timing to prevent continuous-sheet slack, slip, and abnormal noise.

Predictive blank-part potential control uses sensed current and charge data to suppress toner fogging and carrier development in image forming.

Separate drying and transfer heaters let LEP printers control molten film temperature for stronger adhesion without primer.

Relocating the electrical contact holder to the drum cartridge cuts developing-cartridge parts while preserving memory connection through a relay electrode.

A movable brush cleans the toner density sensor surface, then retracts to avoid substrate contact, preserving correction accuracy and low noise.

An integrated agitator and auger improves axial toner conveyance, while housing protrusions guide pivoted mounting and secure fixing in the developing unit.

Longer projections outside the nip spread pressure on the fixing belt, cutting wear while keeping friction low in wide nip fixing.

Temperature-based cooling completion prediction helps users replace a hot fixing unit without repeated checks or unnecessary waiting.
