Scanner Canon appears on both unmodified and modified documents in our corpus. The name alone is never the verdict; each file is judged on its own structure.
Back to all statisticsForensic verdictBased on this tool’s share of the HTPBE? corpus.
Corpus profile
Scanner Canon is one of the PDF-handling tools surfaced in the HTPBE? corpus. Scanner Canon splits its occurrences between Creator (53%) and Producer (47%) roles, meaning it sometimes originates documents and sometimes re-emits them after another tool created them.
HTPBE? reads the Scanner Canon name as one input among many and weighs it together with the rest of the file’s structure – the tool itself is never the accusation.
On documents where Scanner Canon acts as Creator, 32% carry modification markers; on documents where it acts as Producer, 37% do. These are observed rates inside the HTPBE? corpus and should be read as base-rates, not as accusations against Scanner Canon or its users.
Reading guide
Every PDF stores two software labels: the Creator, which names the application that first produced the document, and the Producer, which names the software that last wrote the file out. This page counts the files HTPBE? has analysed where Scanner Canon fills one of those labels, and shows how often those files carry modification markers, which PDF versions they use and which other tools sit next to them.
A tool name tells you where a file passed through, not whether anyone changed its content. A Creator and Producer that agree usually point to a single pass; a Producer that differs from the Creator means the file was written out again by another program, which has many ordinary explanations such as compression, merging or a print-to-PDF step.
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 Canon in the wild. All are merged into the same canonical profile.
Why variants matter
The same tool publishes itself under 30 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 Canon writes when acting as Producer, and the other tools that appear in the same documents.
Most output is PDF 1.4 (62% of files where Scanner Canon is the Producer).

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