077-900 / 077-101 paper jam
What it is
Xerox documents 077-101/077-900 specifically as a Registration Sensor Jam (paper jam detected at/near the registration sensor, e.g. VersaLink B7025/B7030/B7035) — not merely an example of the six-digit code format generally.
Why it matters
Precise codes, business audience, weak content competition.
