Digital BW, The Print

Apparently through trying to print on a photo paper with slightly bent corners, the paper became misaligned with a result (diagnosed on my part) that one of the nozzles got clogged up, and repeated printer-programmed cleaning cycles have failed to clear it.  (The clogged nozzle manifests itself as a while line down the far right side of landscaped formatted prints.)  I read somewhere of a cleaning process for this printer utilizing a paper towel soaked in Windex, but I can't find it anywhere.  Can someone either point me towards it, or otherwise instruct me on what I may further do to clear that particular nozzle? Many thanks.
