C1100 error C2236 and C2237.

Jip there is a couple of hundred wires ends to test...

It's easier if you've got somebody else to help you on the other side of the chassis.

I'll usually use the tone function. I let the other person pick a connector and pin, then I'll find the match. If the tone is wobbly I'll switch to the lowest resistance setting for a better read. It just takes time and patience. =^..^=

Hey great thanks for that idea, used them while i was doing a bit of telecom's. Did not even cross my mind to use that.
Used my scope in a useful manner on site the first time. Used it to verify if the stepper pulses and freq was ok, and it was not.

What i want to do here is sit at the back of the machine where the PRCB needs to go and test from the connectors going to the PRCB to chassis ground.

Excellent reasoning. However, the analog multimeter better identifies the short circuit. In the case of the helper, it also helps a lot. But wires have connections to their full extent. These connections helped me to discard certain parts of the machine.

So 2 hours of testing pins later I cleared the possibility of shorts and installed new board and did firmware.
Any pin described as xSet would also go to ground like fSet tested as grounded.
There is a loop wire in each unit that confirms if its installed or not that grounds it.
In this case fSet was for fuser set and that being grounded would be normal if unit is installed.

Machine came to ready. Jamming. Found bad ICP and connection on the CDB(ADUDB).
Replaced ICP12 and jamming gone.

Last the paper came out all wavey. Found one way bearing on deculer installed wrong way round and corrected that.

Machine running.

Nice work! =^..^=

You have no posts with a sad ending. I already expected an answer like that, coming from you.

Been ask to go look at a machine after its been down for a week or so.
The original call the tech was called out for was yellow scattering.

He tells me the machine was over-toned on yellow and yellow toner everywhere.
Dev and drums were 30% over life at the time.

After he removing cleaning out and installing the drum cradle back, it was just going now warming up forever.
My guess would be that it was not stabilizing ok.
At this he took the fuser to another machine to test and tested ok.

Next he changed the PRCB that poped up with a firmware mismatch that got fixed by updating it.
After that continues giving C2237 and C2236 codes. (IDC shutter failure)
Installing the original PRCB back results in the same.

At this point i got there to check the machine.
PS19 tests ok, but the motor M36 will not budge to move the shutter.
Used IO 55-00 thru to 55-05 with no moment in or out of home position.
Dissembled and check that assy and looks clean and ok. Shutter moves smoothly.
All wire continuity was checked from the board to the sensor and motor.
Next i checked for 24V and that was present on both sides of the ICP so the motor driver is getting juice.
At some point i could feel the holding torque on the motor. The motor itself is fine.

It will give the error on startup even before the transfer belt starts to move.
Could it be that the IDC sensors checks to verify that the shutter is open or closed?
Does anyone know if it will run with out the shutter installed?

I also disabled image stabalization using the soft switches in hope to get a list print or test patern out of service mode.
Engine wants to starts and the the code pops up.

Any advise please.

Try to remove the Shutter and run the machine
are you getting any noise from machine after power on
if Yes then we may need to clan the sensor which is located don side of Processes carriage where exactly shutter motor located

If you read through the entire thread then you will see that the problem was resolved. Long story short a tech used a blower on the IDS assy and damaged a stepper driver on the main board due to a high voltage discharge. Replacing the main board fixed the C223X issues.

But there are a couple of ways to get those codes like the shutter or he sensors.Both can be tested using IO check.
