Power Drive Mechanisms TRIZ Cases
- Multi-Head Cap Positioning for Accurate Liquid Reception
A movable cap shifts across head positions to accurately receive discharged liquid from multiple ejecting heads without separate receivers.
- Dual Maintenance Unit Layout for Inkjet Nozzle Cleaning
Side-by-side cleaning units and negative-pressure suction clear dried ink, dust, and bubbles without increasing inkjet printer size.
- Droplet Ejection Signal Control for Mixed Resolution Printing
Selective first and second drive signals vary droplet volume and resolution to keep carriage speed high while improving print gradation.
- Pivoting Operation Panel Layout for Compact Sheet Discharge Printers
An offset pivot lets a large operation panel overlap the discharge tray while staying above stacked sheets and preserving tray capacity.
- Swingable Wiper Blade Load Control for Inkjet Nozzle Cleaning
A swingable spring-biased blade equalizes nozzle wiping load across multiple heads, removing ink residue without damaging the water-repellent film.
- Printhead Cleaning Unit Lockout to Prevent Belt Collision
A movable cleaning unit is blocked from entering the printhead and belt path except during cleaning, preventing vibration- or contact-driven collisions.
- Recording Head Transport Lock for Vibration Position Stability
A detachable regulating member locks the moving portion during transport to prevent line head or cap unit displacement from vibration and impact.
- Inkjet Print Transport Control for Defective Raster Lines
By shifting transport distance by nozzle-pitch multiples, this case prevents adjacent defective raster lines and preserves print quality.
- Tandem Opposed Inkjet Modules for Compact Four-Color Printing
Opposed tandem inkjet modules shrink the print zone for four-color printing while easing alignment and reducing artefacts at chip joins.
- Roll-Fed Recording Apparatus with Splice-Aware Pre-Ejection Conveyance
An optical sensor detects sheet splices before ejection, while adaptive conveyance protects the recording head and limits waste.
- Recording Head Height Adjustment During Media Discharge
Discharge rollers operate while the recording head changes height, avoiding sequential adjustment delays and maintaining productivity across diverse media.
