Designjet T830 does not detect the paper

[UmbertoUDP]

Hi All,

when I insert an A3 sheet the plotter recognizes the presence and size of the sheet but when I try to print it tells me: The printer is not able to complete the load as it does not detect the paper ....

when I try to load the roll, the roll passes in the path to the front of the plotter but it tells me: "Out of paper"

"The printer is not able to complete the load as it does not detect the paper".

I tried to do the calibration and alignment with an A3 sheet, but nothing ...

What can I do to fix the problem? Thanks

There are two sensors, one mechanical/optical sensor in the paper path that detects top of form and paper out and then there is the optical sensor that the printer uses to detect skew and paper edge. This sensor also reads the alignment patterns when perform a head alignment. This sensor is mounted on the carriage, usually on the left side of the carriage and can get polluted with ink and need cleaning.

Thanks for the info, can you tell me where the first mechanical / optical sensor is placed? So I'll check both of them and let you know if I've solved ... 🙂

Take a look at this service manual:  https://www.dectrader.com/docs/set06/408014/Designjet-T730-T830MFP-Service-Manual.html#pf10e

Page 240 shows a mechanical paper sensor flag on the rear paper path.  Not certain that's the part that failed but will give you an idea where to look at least.  I found the manual by googling the model and "service manual" and there are some other options for service manuals.  This one doesn't show the complete manual but some of the others might.

Hope that helps.

I saw the manual, thank you very much.
Good weekend
