Xerox 3535 HDD 116-330 and PWS won't connect

[Mev]

Hi. I got a Xerox 3535 from a printshop, not working. The owner reported the Xerox tech had said it needed a power supply. He promised to come fix it with a part from another machine, but never did. The owner reported tension between the tech and him.

Digging in, I found it didn't boot up, and gave a HDD error message. I looked inside - no hard drive. I bought a 20Gb hard drive that matched specs. Upon installing, it gave an 116-330 at startup. The machine would only flash to the first of the five circles before displaying the fault code and stopping. I tried 4-STOP-POWERSAVE but it didn't seem to work. Instead it brought me to a screen that said "DOWNLOAD MODE".

I bought an old laptop with Windows XP, a new serial cable, and installed my PWS software. I connected the cable and ran the PWS 3535 Diagnostic Tool. It won't connect to the machine, though I try and try.

Can anyone tell me what "DOWNLOAD MODE" is?

Or, what to do when PWS won't connect?

I'm wondering if it is truly a power supply board. I'm also wondering if that Xerox tech actually took the HDD out and gave it to someone else, and if he might have taken chips also. I'm not sure how to debug these things without PWS.

download mode means its look for a firmware ALTBOOT process. The process is detailed in the service manual ..( you would also know that IF you read the manuaL)
