Question about HP DesignJet 450c InkJet Printer
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?
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.
