Jam Codes and Position Codes

These are lists of jam codes for the main machine and peripheral devices. Please note:

Late jam. The paper has failed to arrive within the prescribed time due to a jam that has occurred upstream of the referenced sensor.
Lag jam. The paper has failed to leave the location of the referenced sensor within the prescribed time due to a jam downstream of the referenced sensor.
