Typewriters TRIZ Cases

Leading-label size detection stops transport on mismatches, preventing label printing errors while preserving throughput on later labels.

By slowing, reversing, and pausing the output roller based on drying time, printed media can dry before duplex handling and avoid distortion.

A rotating receiving member and attachment unit let stand-less printers stack rolled media smoothly while reducing surface damage and jamming.

Direct encoder feedback lets the jetting driver correct stage position error in real time, improving inkjet landing accuracy without higher image resolution.

When a roll-sheet jam stops conveying, controlled sheet supply creates a loop for safer manual cutting and easier jam clearance.

Opposed corrugation members with elastic supports stiffen printed sheets, prevent curling and jams, and keep stapling alignment stable.

Only compatible sheet sizes are shown based on the loaded roll sheet, reducing wrong selections, image clipping, and manual sheet changes.

A dual-picker docking module aligns multiple inkjet heads precisely while speeding sealed flow-path and control-line attachment for easier maintenance.

Selective mirror-guided irradiation lets a page-wide curing array create glossy and matt areas without scanning-unit complexity or vibration.

Pre-drying the substrate while controlling nozzle-area humidity improves aqueous ink drying, limits cockling, and prevents jetting failure.

Side-by-side movable print units create overlap and wider printable strips, cutting small-head cost limits while reducing print voids.

A near-end sensor tracks roll diameter across multiple labels to estimate remaining paper accurately without a complex hold-down structure.

Blank labels are applied to cards before inkjet printing, cutting pre-printed label storage and management while preserving print quality.

Visual pallet stack objects let operators compose mixed print-job output, improving stack planning and post-processing productivity.

A positioning portion, support detection, and ball screw height adjustment reduce platen displacement during transfer to the printer.

Dynamic media requests built from the print queue help operators schedule sources chronologically, reducing manual work and printer stoppages.

When the cover opens, a guidance screen and key operation help time ink tank replacement while keeping the print head capped.

Automatic page-level mode and position selection combines single- and double-sided jobs, eliminating manual reordering for mixed documents.

Category images and color marks help users find changed settings across complex multifunctional image-forming menus.

See how a detachable liquid tank and separate locking mechanism simplify replenishment while maintaining reliable liquid supply.

Stored media profiles and edge detection calibrate new supplies, retract the first media element, and reuse it for printing.

See how print data generation combines automatic tape-length selection with center arrangement, adding margins around the object for efficient tape use.

Dynamic request lists and agenda-style scheduling help operators load print media sources before queued jobs cause downtime.

Pigment-ink printing can produce uneven gloss; selective image-data processing applies clear ink only where needed to limit excess use.

Automatic ink circulation during warm-up enables rapid startup and remote maintenance of inkjet marking equipment.

Adjustable nozzles drip colored inks into powder cakes, avoiding inkjet clogging while creating deep, varied shades.

Dual ejectors coordinate pretreatment and recording liquids to balance absorption across both sheet surfaces and suppress curling during printing.

A dedicated grounding member grounds the conductive contact section, stabilizing the rotating shaft path while reducing bearing design restrictions.

Users can change server-managed contract information on the image forming apparatus, restoring restricted functions without an external device.

Cameras build a 3D finger model so spray nozzles can align accurately despite hand movement during nail decoration.

Optical gap measurement with a reference block and camera protects the nozzle while stabilizing sealant volume and linewidth.

A movable placement mechanism routes printed stones between heating, storage, and cooling paths so mixed ink curing avoids line blockage.

Linerless labels can wrap around the platen roller; a hinged cutter moves away to expose jams and sensors block blade operation when disengaged.

Upstream and downstream rollers apply tension beside the image-capturing element to hold distance and reduce conveyance friction.

Dual sensors detect sheet presence and marks to speed sheet-type checks while avoiding unnecessary reverse conveyance and cutting.

Uneven droplets in overlapping curved-surface regions are addressed through path angles and overlap widths to reduce white spots.

To verify print quality without enlarging the printer, a reader is placed on the take-up path below the print head.

Laser remelting diffuses hot melt ink into the substrate, improving label rub resistance and legibility.

Converting continuous liquid flow into droplets helps apply small amounts uniformly to a medium with high energy and accuracy.
