I had great fun today stripping down my wf 4640 to see if i could clean the print head. Did the job and then hit a hurdle in the last few moments. My photo taking missed this one crucial element.... after taking off the front lcd panel and pulling out the speaker and the data cable and earth. Then reassemble..... I am left with one door cable that I cant seem to find the white clip for? This comes out in chip near data cable... any ideas?
