Designjet 330 all lights on the front panel are blinking. very quick flashing

According to the manual, a blinking green power light indicates that the unit is transition between off and on.

There are free software you can download for this designjet 750c by finding at websearch like yahoo.com or msn.com. Just type the driver name for this printer and you can download it for free. Most of the printer driver now can be downloaded online with free cd key. Just let it try. or Maybe the printer you are installing is not compatible with windows 7. try to read you printer's user manual.

Probably a bad trailing cable. I've seen it many times.

Guys

1. Thanks for coming up for air
2. We figured out the problem
3. It's a master panel board in the bottom right corner of the printer
4. At this time we will be throwing out this HP 330 and getting another

Thanks for your help.

The " Trailing cable " is bad.
also check carriage belt..............good luck.

If you are seeing the blue light blink and then go off, the headset is powered on. The blue light does not continuously flash while the headset is powered up. Try making a phone call or pairing the headset to your phone to see if it recognizes that you are trying to use it.

The same Ram can be found in old desktop computers, 486 is about the right time for a 16mb or 32mb RAM chip.
