Other Printing Apparatus TRIZ Cases

A shared transmission module lets one printer motor feed continuous and cut sheets, automating mode changes while reducing manual substrate handling.

Temperature sensors track ejection-related changes so a control engine can identify blocked or non-operative nozzles and improve fluid-drop reliability.

A controller checks cover position and container use, continuing printing with an alternative ink container when possible.

During container connection, a contact portion compresses the storage space, raises pressure, and reduces bubble clogging in ink supply.

Identifying roll-sheet type during conveyance lets the control unit adjust operation settings, reducing conveyance time and failures.

A movable flow passage member seals the atmosphere port when detached and opens it during attachment to limit ink leakage.

Micrometer-scale protrusions create an air layer that repels water on printed matter, avoiding fluorine treatment and reaching about 100° contact angle.

Asymmetric handle heights align lifting posture with gravity, stabilizing the ink printer and reducing shaking that can cause liquid leakage.

A two-stage standby sequence reduces power after printing while preserving faster return from the first mode to printing.

Separate base and image-wise pattern layers combine batch manufacturing with individual document customization for durable, visible security features.

An elastic flapper holds a rolled sheet against the printer housing while its rotating protrusion signals low paper through a sensor.

Dual temperature signals correct print-head readings despite measurement variation, improving liquid discharge control and ink fixability.

A printed color pattern gives an optical reference for confirming wiping-liquid application and maintaining consistent nozzle cleaning.

A localized constricted reinforcement keeps the hopper rigid as side-guide travel expands for different media widths.
