20 Most Recent HP DesignJet 330 InkJet Printer Questions & Answers

unfortunatly the only fix is to replace the firmware chip itself which requires a new main PCA/formatter, I would suggest with the age of this unit that would be most difficult to get hold of and would probably cost more to repair than it would be to procure a 2nd hand more recent unit

A clog print head noozle sometimes the cause of this problem, so try to clean it and try plug again

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.

This indicates that either the black print cartridge is faulty, misplaced or missing. Try inserting a different black cartridge. Also firmly press the large green plunger fully down once, and then release it. The plunger should return to its original position. Then reset the printer and try printing again. If the problem persists try using a new black cartridge and primeit before use with the power on.

79 errors are usually bad firmware that needs replaced or updated. Sometimes it is simply a bad print job being sent. Check to see if only one print job is causing this error, or if it happens with everything you try to print.

The dates are on the package for a reason. The ink dries out or changes viscosity over time and will likely clog the printhead. My advice is not to stock up on cartridges because of this problem. If you look online, you can find replacement chips or instructions on how to reset the chip on the cartridge.
