HP Color Laserjet 2600n Color Alignment

Question

There is a color shift or "ghost image" on certain colors (it looks like the colours are out of alignment). When printing a color test page the magenta band is shifted to the right. The orange band has a 2mm yellow stripe on the left and a 1mm magenta stripe on the right. The DC Controller firmware is updated: cpr in the beginning and EV = 2F. I had calibrated numerous times and reset back to defaults. Will a firmware update fix this problem? My firmware version is 20050610 but I cannot find where to download the firmware update anywhere on the hp website. I am using genuine HP toner cartridges.
