Scanners (except combination of printer, scanner, copier and/or fax)

1. Scope and Applicability

This PCR covers standalone computing-input scanners that digitize documents or images, including flatbed and sheet-fed models. Exclude integrated printer/scanner/copier/fax combinations, medical diagnostic scanners, three-dimensional metrology scanners and barcode-only readers. The manufacturing module delivers tested equipment at the factory gate. Optical architecture, accepted image quality, test losses and the supplied accessory configuration require product-specific collection; printer consumable assumptions do not apply. Scope follows un-cpc-3-0-structure-2025 and the scanner distinction in epa-imaging-equipment-v3-1.

3. Reference Flow

Field	Value
What	Digitization of declared original formats
How much	Manufacturing declared unit: 1 kg net accepted scanner equipment; convert to one complete scanner using measured kit mass m
How well	Declare optical resolution, color depth, document size, simplex/duplex throughput and acceptance test criteria; do not equate kg with scanning performance
How long or cycle	One manufacturing and acceptance cycle. Service comparison requires separately declared lifetime pages and years; no default lifetime
reference_flow_link	scanner_output = 1 kg; manufacturing burden per scanner equals burden per kg multiplied by m. This is a partial manufacturing module, not a complete service comparison.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
net_mass	scanner_output	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Weigh accepted kits separately from packaging. Use model-specific count × measured kit mass; never substitute shipping weight.
electricity_units	electricity	Net calorific value 93a60a56-a3c8-11da-a746-0800200c9a66	MJ	Retain meter kWh and convert by 1 kWh = 3.6 MJ. Nameplate power is not measured factory energy.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Finished purchased components and empty packaging received at assembly plant
starting_condition_role	Supplier-linked assembly foreground; raw-material and component production upstream
product_classification_scope	Standalone computing-input scanners; not scanner parts as finished product
recursive_input_rule	A purchased complete scanner requires a separate assembly/refurbishment route with its own supplier inventory; never recursively expand the same complete-scanner output as its own input
upstream_dataset_requirement	Link each component to matching supplier production and delivery datasets. Missing upstream coverage is a disclosed gap, never zero burden.
disclosure	Report component manufacture locations, purchased/on-site split, accessory and packaging scope, and exclusions

rule_id	applies_to	Rule	source_ids
manufacturing_boundary	manufacturing	Include assembly, calibration, testing, rework and packing with linked upstream supply and factory waste treatment. Disclose excluded distribution, use and end-of-life stages; never claim a full life cycle from this module.	ghg-protocol-product-standard-2011
bom_completeness	foreground	Reconcile the actual bill of materials. Cards below are common atomic exchanges, not a universal bill. Add each installed CCD module, feed roller, fastener, alternative housing, cushion or actual factory chemical as its own identified exchange when present. Verify absence rather than assume zero. Avoid double counting supplier assemblies and their internal parts.	epson-gts55-scanner-parts; epson-v19-v39-scanner-parts

7. Allocation and Co-product Handling

rule_id	applies_to	Rule	source_ids
subdivide_first	shared_operations	Use dedicated line records first. Allocate remaining shared burdens using demonstrated physical drivers; justify economic allocation only where a physical relationship cannot be established.	ghg-protocol-product-standard-2011
