No colour Dell printer

  benson68 17:36 14 Mar 08

Anyone know how to get a Dell printer cleaned ?(presumably)
With new cartridges installed, it will only print from the RHS cartridge. I presume that, coloured black, this is where the black cartridge goes, & it prints perfectly, but nothing comes out of the LHS colour cartridge. Coloured ink comes out of the colour cartridge when it is installed in the RHS carrier, but then the black (installed in the LHS) doesn't work!
Can anyone help?
