2.5.2.2 Delay Jams
2.5.2.2.1 Pickup delay jam 1
If the registration sensor (SR4) cannot detect the paper leading edge after the image format starts until the re-pickup is started.
2.5.2.2.2 Pickup delay jam 2
The manual feed tray pre-registration sensor (SR7) cannot detect the paper leading edge within a specified time after manual feed tray pickup starts.
2.5.2.2.3 Fixing delivery delay jam
The fixing delivery sensor (SR8) cannot detect the paper leading edge within a specified time after the re-pickup starts.
The delivery full sensor (SR15) cannot detect the paper leading edge within a specified time after the registration sensor (SR4) detects the paper trailing edge.
2.5.2.3 Stationary Jams
2.5.2.3.1 Pickup stationary jam
If the registration sensor (SR4) cannot detect the paper trailing edge after the re-pickup is started.
