The slides you are moving are for the drum units, you could try using canned air to blow in the same area that the sliders slide across, if that doesn't help you may need a new drum unit..

The green tabs that you have to slide are under the color cartridges, so remove the three color cartridges and you will see three green tabs, to slide the tab across the wire you have to first open the translucent plastic wire cover, then slide the green tab across the wires and return it to it's original position, close the wire covers, replace the color cartridges, and reassemble the printer. All the Best

The green tab slides from left to right.
This cleans the croner wire. These wire also have a tedancy to break every often.
The drum unit will need to be replaced
