epson 7600

[nicknack96]

Need parts listing or schematic for Epson 7600. Have clogged nozzle and need to "puddle the cap and park the print head for thirty minutes ( in a solution of 10% ammonia and water)." Not sure where the cap is. Any information on this would be most helpful. Have the service manual already, but it doesn't contain this info.
Thanks.[b]
