laserjet cp1025nw colored dots down the page

Very frustrating - colored dots printing down the page on every printout.  laserjet cp1025nw  Genuine hp ink and drum.  cleaned the contacts with electronics cleaner.  it is not a print quality issue - these are being put there by the printer.  if printing in b/w then only black dots.  full color then all clolors.  There is nothing on the drum or toner cartridges.  did a firmware upgrade and hard reset and same issue.

Check the secondary transfer roller for toner pollution. Can you post a sample?
