I have struggled to solve the above error for a while on a Designjet 500.
Following has been done to fix the problem so far:
1. Clean and oiled the shaft
2. Replaced the Carriage belt
3. Replaced the Trailing Cable
4. Replaced the Service Station
5. Replaced the Encoder Strip
6. Upgraded to latest firmware
The carriage moves smoothly all the way.
Still same problem.
The power switch does not work so I have to plug in and out the power cable.
When power up the sequence goes to "Close Window", when that is done the Carriage moves app. 1 inc. to the left and then back and then the error message appears. This is independently of position. When try to power off via the power switch the indicator LED flashes with even period.
I have tried to look att similar posts and bobmcm581 09-26-2013 had exactly the same problem but I can not find any fix to this anywhere inspite of that long time has passed from the previouse conversation.
I would really appriciate any information or idea how to resolve this.

Before replacing anything else, it may be worth looking at the attached document, it may help especially as you said the power switch LED is flashing.

Thank´s for the input.
I will check the sensor and update firmware again.
I will let you know the result.
Thank´s a lot!!

I have followed your suggestions by checking the sensor (H97200335.P) in the carriage (located in the right hand side, see photo) but no visible sign of any obstructions and updated the firmware to A.04.02 successfully.
Still same problem.
I will order a new sensor and see if there is any component error.
Any other input??
All input is welcome!!!

Thank´s for the suggestions!
1. The encoder strip is installed correct with the metal base down and the plastic strips on top.
2. The sensor you describe to detect the paper edge is located to the left on a plastic arm.
3. The encoder strip passes in front of the shaft where the carriage assembly slides and the sensor is situated so that the transmitter and reciever of the sensor is on each side of the encoder strip.
I see following remaining error sources:
1. Sensor component error (I have not found any replacement for it yet?!)
2. Carriage assembly PC board error
3. Electronic module error
4. Motor failure (very unlikely since the carriage moves an inch to the left and then right again)
5. Power supply error. I measured the 32V and found 29,7V in idle state. Could that imply a "to slow=time out" reaction from start to actuation of the carriage assembly so the logic thinks it is an obstruction?
It would be great to have the source code to see what line 638 in the code means? If it is "too long delay from actuation to reaction" then maybee this can be the reason??
Thank you again for the contributions!!

Now I have replaced the carriage assembly - SOLVED !!
No more 86:01 code and the carriage assembly works well!!
Now I just have to clear all the "normal" issues with printheads etc. but this is a major step ahead!!
Probably the sensor for the carriage movement was the problem OR a static electricity had killed a component on the board.
Thank´s a lot for your valuable assistance!!!
