8. Door open jam.
2.5.2.2 Delay Jams
2.5.2.2.1 Pickup delay jam 1
0021-1323
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
0021-1324
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
0021-2014
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
0021-1325
If the registration sensor (SR4) cannot detect the paper trailing edge after the re-pickup is started.
