I just made a really cool drag knife holder for my HP 7475 to cut vinyl stickers but I am unable to get the plotter to work. The error light on the front panel keeps blinking on and off and I can't get it to respond from any commands sent to it through DOS. The plotter will change pins, go into view mode, even print the demo sheet just fine, but the error light still keeps flashing. If I press the enter button and view button together the plotter does not reset. I bought a new serial null modem cable and hooked it up to my computer but I get no response out of the plotter when I send a DOS command. Is it because I am running Windows XP and accessing the DOS window to send the DOS commands, or do I need to be in a real DOS enviroment. It's as if the plotter is stuck in some error mode and will not accept any commands fromt he computer. If anyone has any ideas or help please let me know. I really what to get this plotter working so I can try my hand at sticker making. If it works I'll share my drag knife holder design with everyone. A little background on the plotter, it was given to me 5 years ago and I never hooked it up until now. I would think since the demo plot function works great that it would work, if can get rid of the error light and get the computer to talk to it.
Thanks in Advance
