Stopping the upstream and downstream conveyors in sequence stabilizes sheet posture, improving patch image reading accuracy and reducing jams.

Measured heater temperature is compared with predicted film temperature so fixing power can adapt to airflow and prevent fixing defects.

A widened flange backed by the heater holder resists thermal deformation, keeping the heater aligned and belt travel stable.

Indication markings on a detachable sheet tray replace bulky width restrictors, keeping large-sheet feeding compact, light, and stable.

Center-position CIS edge detection corrects image placement on subsequent sheets, reducing width-direction misalignment in duplex printing.

A digital resolution conversion unit lets image readers use different sensor pixel pitches without optical redesign, cutting cost and speeding scans.

A spring-loaded holder regulates the follower roller to keep nip pressure uniform, reducing skew and misalignment in small-sheet conveyance.

A rotatable entrance guide adjusts to sheet stiffness so sheets enter the fixing nip smoothly, reducing impact, image unevenness, and wrinkling.

A staggered chip and sealing layout keeps light emitting areas closer to the lens array, reducing condensation loss while maintaining moisture protection.

Width data is preserved across power loss so the fixing unit can lower heat for wide sheets and avoid high-temperature toner offset.

Usage-based toner estimation converts print ratio, daily volume, and remaining toner into printable sheets and days to avoid early cartridge replacement.

Measured AC voltage and zero-cross timing protect a fixing heater from overvoltage damage while keeping printing available.

A movable tray and cam-held separation member let half-moon sheet feeders extend feed distance without losing sheet detection.

Test-bias feedback adjusts fur brush voltage as wear raises resistance, sustaining toner removal and preventing charging failures.
