This machine detects a jam using the sensors shown below. Document jam check timings are stored in the ROM on the image processor PCB to check whether a
jam has occurred according to presence/absence of the document at the relevant sensor position.
When a jam occurs, the host machine stores its code.
Jam codes can be checked by outputting a jam error log report in the service mode of the host machine.

Sensor No. Description
- Other errors
SR2002, R2003, SR2004 Paper is detected in the transport path before the ADF starts initial operation.
The document edge sensor does not detect paper when the paper has been fed by the
predetermined distance since reception of a pickup request.
SR2002 The trailing edge of paper is not detected when the paper has been fed by the
predetermined distance since detection of it by the docement edge sensor.
SR2001 The document set sensor has been held off since start of pickup.
SR2002 In case the internal software signal "Delivery Sensor ON" set in the system cannot
be detected, when the paper feed request is received and the paper is fed the
prescribed distance, and the leading edge of paper is detected and paper is fed the
prescribed distance .
SR2002 In case the internal software signal "Delivery Sensor OFF" set in the system cannot
be detected, when the leading edge of paper is detected by the document edge sensor
and fed the prescribed distance, and after the paper's trailing edge is detected.
SR2003 The registration sensor has been held off since paper pickup started.
