Most likely the media (paper) is touching the print heads. This can occur because 1) the media holding mechanism is not holding the media correctly, and the media buckles, or 2) the carriage to media distance is too small. (Check the adjustment in chapter 5 of the manual). I found a copy of the procesure online: HP DesignJet 430 Service Manual Adjusting The Carriage To Media Distance

That usually is caused by clogged or damaged printheads. There are 4 printheads, Black, Cyan, Magenta and Yellow. When you replace the printheads you need to calibrate the machine so the colors line up with one another.

First off, if you touched the metal contacts on the printer or cartridge, you could damage or leave a film on the contact surface. Take it out of the printer, with a qtip dip in rubbing alcohol, squeeze out access, rub surfaces, air dry, and reinsert again. If still no ink, turn the print end up under the very hot water tap and run for 2 minutes. Dry and replace. It may do the trick.

First try the driver for XP

If that does not work try the driver for the designjet 500 or 430 sometimes a like model driver will work.

More than likely one or more of your color printheads are worn out and need replaced...they are around $40 - $50 each and are relatively easy to replace.
