Ir advancC9280 pro E075-002

[CT Copier Repair]

Machine goes into error
first ti,e found the spring popped
reseated it and it tried to make a copy and jammed
found broken paper actuator so I replaced that
now in a hard e075-002 again

Looked at the sensors if I'm reading it correctly P03 bit 12 should read 1 its at 0
I moved it and no change
and just to make sure I'm not losing my mind the 0 bit is the 1st left rianbit
been awhile since worked on canons been mostly Xerox and KM production machines

Thanks
Brian

CHECK>if the intermediate connector J8010 is half way out on frame side of the ITB drawer connection.
If so >Re seat the connection and verify all other ITB connections from the frame side connection back to the dc controller.
Tip: If you are having difficulty reconnecting the connections to the intermediate connector (because the wire length is too short), the intermediate connector can be reversed. This way you can plug the connector into the intermediate connector and the then snap the intermediate connector into the connector holder bracket.

And the 1 on position is the flag actuated out?
I think the machine was dropped and I remember reading that these things are really sensitive and need to be perfectly square or the E75 is an issue

1) When the ITB is displaced to the front side or rear side, the edge of the ITB activates the ITB displacement sensor flag.
2) The position of the ITB Displacement sensor flag is detected by the ITB displacement sensor (PS2) (Refer to <Detection of ITB position>). The ITB steering motor (M4) is driven according to the position of the ITB.The ITB steering motor (M4) is driven according to the position of the ITB.
3) When M4 is driven, the steering cam rotates and the support arm moves up and down. This operation tilts the steering roller.
4) When the steering roller tilts, a difference of tension is generated on the ITB, and the ITB moves to the front side or rear side.
5) The operation from Step 1 to 4 is repeatedly performed to correct ITB displacement.
6) The position of the steering roller is detected by the steering roller HP sensor (PS3).
7) The HP mark (white) on inside of the ITB is used when correcting unevenness on the edge of the ITB that is detected by PS3 (Refer to <Profile of ITB edge shape>).

NOTE:
When replacing the belt, be sure that the HP mark (white) is located on the rear side.

<Detection of ITB position>
ITB Displacement Sensor (PS2) consists of LED and 2 Photo Diodes (PD). Due to the position of ITB Displacement Sensor Flag, photo intensity of 2 PDs in ITB Displacement Sensor (PS2) varies. By detecting this photo intensity, the belt position is grasped.

<Profile of ITB edge shape>
ITB edge is shaped in the wavy line, not in the straight line. Therefore, if the ITB position is detected without considering this ITB edge shape, the correct position cannot be detected.
This edge shape varies in each ITB.
At ITB replacement, the profile of ITB edge shape is created using the service mode and recorded. By referring to this profile and measurement result by ITB Displacement Sensor, the correct ITB position is detected.
ITB HP Sensor (PS5) detects the HP mark (white) on inside of the ITB, creates the profile and recognizes the standard position at ITB displacement correction.

Where in service mode is the ITB profile created ?


I looked but then again Im dumb and its Friday

_____;
What profile ?

[vigour]

You need to remove the ITB, check if the belt is off centre.
you could remove the belt, clean the drive rollers and run ITB INIT after replacing the belt.
It is the adv 5000 series which needs to be levelled.
