Scanner Fujitsu appears on both legitimate first-generation output and downstream re-save flows — context (the other tool on the same document) is what flips the signal.
Back to all statisticsForensic verdictBased on 18 appearances across the HTPBE? corpus.
Corpus profile
Scanner Fujitsu is one of the PDF-handling tools surfaced in the HTPBE? corpus. Scanner Fujitsu splits its occurrences between Creator (61%) and Producer (39%) roles, meaning it sometimes originates documents and sometimes re-emits them after another tool created them.
In the HTPBE? corpus the contextual signal we look for is a producer/creator mismatch: when Scanner Fujitsu appears as the latest Producer on a document whose Creator was an institutional source (e.g. Adobe PDF Library, Microsoft Word, a banking back-end), the document was rebuilt or re-saved after its original creation. That mismatch is the marker — never the tool itself.
On documents where Scanner Fujitsu acts as Creator, 45% carry modification markers; on documents where it acts as Producer, 14% do. These are observed rates inside the HTPBE? corpus and should be read as base-rates, not as accusations against Scanner Fujitsu or its users.
Role in the workflow
Every PDF carries a Creator (the application that produced the original document) and a Producer (the engine that wrote the PDF). The same tool can appear in either slot, with very different modification profiles.
Name fingerprints
Different version strings and spellings observed for Scanner Fujitsu in the wild. All are merged into the same canonical profile.
Why variants matter
The same tool publishes itself under 11 different metadata strings — version bumps, locale tags, build IDs. We canonicalize them so the corpus reflects one identity, not noise.
Distributions
The PDF versions Scanner Fujitsu writes when acting as Producer, and the other tools that appear in the same documents.
Most output is PDF 1.7 (67% of files where Scanner Fujitsu is the Producer).

Long tail
Smaller cuts of the Scanner Fujitsu corpus — useful context, but treat each row as a single data point rather than a strong signal.
