Clip, clip, where is the clip? HP deskjet960c

I had a paper jam on my HP deskjet960c, cleared the jam and lights kept
blinking and the printer was inoperative.

I went to the HP support website online and found ALMOST exactly what I
needed in the FAQs. However, the critical point requires that I take a
flat head screwdriver and push on a silver clip to release the carriage
and bring it back to center.

The illustration showing the clip is inadequate and as a result I can't
identify the clip.

HP provides no further support.

Can anyone help me to identify this elusive release clip?

Thanks,

Rob
