Thanks. I'm a complete noob regarding HP plotters. Where to find that line sensor....?

Sounds like you need to read the service manual.

OK, now I know what we are talking about and I know where that sensor is located. However, when one is having this error code does it mean that the sensor has to be replaced anytime or are there workarounds such as cleaning?
Have to go tomorrow to the customer and have not yet seen the machine...

Thanks

Hans I've been in your situation working on machine never met. Number one priority - get the f. manual . Start from there then listen to professionals here advices. Chances are small one not seeing machine ever solves the puzzle from first visit. You will need directions and know for what to look then work from there.
Good luck

Re: HP DJ T795, error 55:10

In my experience the sensor has to be replaced. Any attempts I've made to try and clean it failed. Fortunately it's fairly simple to replace and inexpensive.

Note that you can not move the carriage without first disengaging the service station. Easiest way to do that is to turn on the printer, and when it starts to move the carriage, pull the power cord. Then the carriage is free to move around.

+1 on the simplicity of the repair and moving the carriage assm. (Pretty much the same on ink based plotters)

Guys have been there just now.
When the machine boots up the carriage does not move at all but is showing in the display initializing until 67% than breaking off and giving error 55:10. With occasionally Error code: 0x10504003 in between.

Any ideas please? Could the hard drive play a role here?

Re: HP DJ T795, error 55:10

So it's failing while initializing the carriage assembly (and not reaching the point where it moves the carriage.) I would replace the line sensor first and see if that takes care of it.

Follow the instructions in the service manual regarding freeing the carriage. There's a hole in back that you can stick a T-15 and you have to turn it about 200 times to move the service station to the point where the carriage will be free.

HP has the line sensor in stock. CR647-67024 It's $32 plus shipping.

Re: HP DJ T795, error 55:10 **SOLVED**

So, finally went there. To unlock the jammed carriage was no fun and it needed a LONG T10 but we managed. Replacing the Line Sensor was a 10 minute job and the plotter started after that booting as hoped. Progress was at 94% all the time end the machine was making endlessly "something" in the station at the right hand. Not sure, since I'm not familiar with plotters, but I think it was continuously priming the ink system or flushing the heads with precious expensive original HP-Ink, but that's the customers problem......

It took about 15 minutes before being ready and starting from itself printing jobs still in the pipeline.
Prints (plots?) where flawless after this. Customer happy and me happy on Friday late afternoon.

Thanks for your help guys
