Purpose and description
Enable an AI agent to recognise an image scanner, assess its capture readiness and limitations, and choose a suitable, non-damaging digitisation operation.
An image scanner is an optoelectronic input device that samples light reflected from or transmitted through a physical original to produce a digital raster image.
It can be Select a compatible capture path, holder or accessory for the original.; Configure capture area, spatial sampling, colour mode and simplex or duplex acquisition.; Preview an original and adjust positioning or crop before final capture.; Acquire an image and check completeness, orientation, focus and visible artefacts.; Cancel acquisition and recover an original using the documented transport procedure.; Clean accessible optical surfaces, calibrate the system or service feed components when indicated..
Distinguishing features
Produces a raster representation of an original through a dedicated acquisition arrangement, rather than merely displaying, printing or transferring an existing image.
Provides a defined capture area or acquisition path that governs how the original is positioned, moved or traversed.
Captures the visual image rather than only returning a decoded identifier, as a dedicated barcode reader may do.
An overhead scanner may use a camera sensor; distinguish it through its dedicated original support, illumination and capture workflow rather than sensor technology alone.
In a multifunction device, identify the optical acquisition subsystem separately from the mechanism that marks paper.

Original and capture boundary Establishes which originals the scanner can capture and how its acquisition assembly is bounded.
Scanner identity and suitability depend on the original, illumination mode and positioning mechanism, not merely the presence of an image sensor.
Acquisition identity
Locates the scanner function within a standalone device or a larger assembly.
Dedicated scanning arrangement
Record the arrangement that presents an original to the optical system and distinguish the scanner kind from a product model or individual unit.
- What dedicated positioning, illumination and acquisition arrangement makes this an image scanner? definition
- Is the scanning assembly standalone or part of a multifunction device, and where does its functional boundary end? boundary
Original compatibility
Describes the physical and optical conditions under which an original can be captured.
Supported original envelope
Record supported sizes, media, illumination modes and mounting requirements, including exclusions for fragile or irregular originals.
- What width, length, thickness or object height can each capture path accommodate, in millimetres? measurement
- Which originals require transmitted light, a special holder or a non-feeding capture path? action
- Which documented restrictions exclude bound, curled, stapled, adhesive-bearing or fragile originals? provenance
Optical capture and fidelity Describes how the scanner samples an original and how delivered image quality can be assessed.
A scanner may produce a large image file without resolving the detail, tones or geometry required for the intended use.
Sampling and tonal capability
Separates acquisition capability from output settings and software processing.
Native versus delivered image
Record native sampling, selected output sampling, colour channels and tonal precision without equating these settings with verified image quality.

- What colour modes and delivered bits per channel are available, and how do they differ from internal processing precision? measurement
Calibration and image assessment
Connects calibration and controlled checks to the fidelity of acquired images.
Capture quality evidence
Record evidence of detail reproduction, tonal response, colour consistency, illumination uniformity and geometric accuracy under stated conditions.
- Which target, procedure and capture settings support the assessment of focus, tonal reproduction, colour and geometric accuracy? provenance
- What observed streaking, clipping, shading, blur or distortion requires cleaning, recalibration or a different capture arrangement? action
- Which automatic corrections affect the output, and can they be disabled when an uncorrected capture is required? action
Scan operation and delivery Covers original movement, capture sequencing and delivery of acquired images.
Successful scanning requires both complete physical acquisition and reliable association of each output image with its original and side.
Positioning and sequencing
Describes placement, feed behaviour and the sequence of captures.
Complete original acquisition
Record alignment, selected area, side handling and transport checks needed to avoid missing, duplicated or truncated content.
- How must the original be oriented and positioned, and how are capture edges or crop boundaries established? action
- How does the scanner handle both sides, detect multiple feeds and preserve page order where those functions apply? definition
- What acquisition time or throughput is achievable at the required settings, with pages and images counted separately? measurement
Control and output handoff
Identifies control dependencies and the evidence that image transfer has completed.
Retrievable scan result
Record supported control interfaces, output paths and completion signals, separating device acquisition from downstream interpretation.
- Which documented interface, driver or application can configure the scanner and retrieve its images? provenance
- How can an agent verify that every intended image was acquired and delivered after a cancellation, connection loss or retry? action
- Which output transformations occur in the scanner, and which belong to host software or a downstream document service? boundary
Readiness, care and safe recovery Connects scanner condition, original protection and maintenance to permitted operations.
Dirty optics, worn feed parts, unsuitable power or unsafe recovery can degrade captures or damage originals even when the scanner remains responsive.
Readiness and protection
Establishes prerequisites for scanning and constraints during faults or access to moving parts.
Permitted capture state
Record power compatibility, startup status, transport locks, covers and any documented protective mechanisms before permitting acquisition.
- Which power, initialisation, transport-lock and cover conditions must be satisfied before this scanner can acquire an image? action
- Which protective mechanisms are actually fitted, and what operator actions are required when they stop or inhibit scanning? provenance
- Which safety or electromagnetic-compatibility requirements and conformity marks are documented for the product and intended jurisdiction? provenance
Maintenance and fault recovery
Relates observable defects to documented cleaning, replacement and recovery procedures.
Restore capture without original damage
Record cleaning access, feed-component wear, calibration needs and recovery procedures appropriate to the scanner configuration.

- What documented procedure releases a jammed or mounted original without tearing, scratching or exposing the operator to moving parts? action
- Which surfaces, rollers, separation components or calibration materials require cleaning or replacement, and on what evidence or interval? action
