C5235 / 5240 / 5250 / 5255
E0029 0003 was displayed on boot-up.
It was noticed that the patch read sensor value P-LED-DA was 0.
On a properly working machine this number is typically around 15-22.
It was found that the wires to the patch shutter solenoid were being smashed in the wire saddle connector directly below the solenoid.
Re-positioning the wires correctly resolved the error code and the P-LED-DA values returned to normal.

Canon Tech had already replaced the patch sensor and shutter, as well as the Feed Driver PCB for this C5235.
In this case, the C5235 DC Controller, (FM4-9390-000) was defective and was replaced to resolve the E029 error code.

Machine would display an E029-0003 error code at boot up.
The error code description is:
The reflected value from ITB was lower than the lower
limit when adjusting the light intensity of patch LED.
Found that fuse FU2 was blown on the Paper Feed Driver PCB.
The Registration/Patch Sensor Assembly is powered from fuse FU2.
Replaced the Registration/Patch Sensor Assembly and the Paper Feed Driver PCB to resolve the error.
Registration/Patch Sensor Assembly iRAC5000 and iRAC5200 series
both use part number: FM3-5944-000
Paper Feed Driver PCB
iRAC5000 part number: FM3-7932-000
iRAC5200 part number: FM4-9391-000

Check the Registration Patch Sensor Shutter/Linkage.
In this case, when booting up the machine, the linkage never moved.
The linkage/shutter was stuck and manually activating it resolved the issue.

E029-0003 Error Code is occurring along with a 'check printer' message.
Error code E029-0003 refers to an ITB light intensity error.
In this case, replacing the Feed Driver PCB along with re-seating connectors on the DC Controller and lasers resolved the error code and message.
The part number for the Feed Driver PCB is FM4-9391-000.
