The plotter is not loading the media. It starts up. in first instance I can choose between roll and sheet. When I try to load the paper and push the big square blue button to start loading the paper, the plotter does not do anything. At that point I cannot choose again between roll and sheet, the panel lights are frozen now.
The tech says it is the big main board though he tried a new loading switch -big blue button- but it did not do anything. I say, could it be the front panel assembly board-where the lights are? I cannot understand how it can be the big main board with the power supply though it starts up. Any ideas?

Re: HP designjet 430 E Plotter
The reason it could be the main board is that it tells the front panel lights what to do. This seems like a logical problem the printer is having, usually things freeze when internal memory is bad. Surely have the main board replaced. There is a part of the internal programming that it cant get past. Compare it with trying to read a sector of a cd-rom that is scratched.

This could be an issue with paper jam in the printer or out of paper sensor. Open the top cover (with HP logo) and check if any paper is stuck inside the printer, specially in the corners. This could also be an issue related to roll loaded in the sheet slot.

I would check the sensor on the carriage that detects paper. It might be dirty enough that printer cannot detect the subtle edge of the clear film. It is the blue light that turns on on the bottom of the carriage when you load paper.
Hi, This is the problem with the sensor. It tries to read the size of the paper, the sensor is on the side of the carriage assy(cartridges are installed on this assy). You can try cleaning this sensor or get it replaced or some times the service center will replace the carriage unit as a whole.
When you load the paper, the carriage edge detector measures exactly where the right edge of the paper is located. Then the paper is rolled forward and the edge is measured again. If there is a difference in the measurements, the printer assumes the paper is not loaded squarely and rejects the paper. After you load the paper and the printer asks you to align the paper, take your time, release the paper with the release lever, and line up the right edge of the paper with the right edge of the paper roll. You might have to do it more than once to get it to load. Some plotters are very sensitive and others are more forgiving.
I don't know if you are running in sheet or roll media, but we have this problem with roll media if it is not aligned properly. Usually if I release the media lever and pull 10-12" of paper through and align it with itself and with the dotted line to the right of the plotter, then it will accept it. Sometimes takes several tries. Sheet problems may be caused by dirty sensors. Good luck.
the plotter measures the media automatically. There is no size setting,only type of media.If you want to print on 8.5x 11 only a few times,load a sheet to print on bysimply lifting the cover an aligning the sheet on the blue lines ,on the right side.If you plot a lot,I suggest get a 11" x 150' roll.
hope this helps
