Peel off the cover tape.
The tape is in two layers – one called “carrier tape” that contains the components and the other
called “cover tape” that covers the components on the top. Remove the leading portion of the cover
tape in advance to the extent that the tape reaches the winding roller.
5
Set the carrier tape.
Run the carrier tape through the hole in the tape guide front lever.
6
Set the cover tape.
Run the cover tape through the notch in the tape guide assembly (or tape support plate). Be sure to
peel off enough length of tape so the cover tape reaches the take-up roller.

Edge delamination
12 mm, 16 mm and 24 mm tape guides can be used without passing the cover tape into the notch
of the tape guide assembly. This method is called "Edge delamination".
Generally the edge delamination has the advantages that cutting down the component waste, or
priventing scratch on component surface (caused by deformed tape guide assembly or so). Though,
as the static cling of component may cause pickup error, YAMAHA recommend "delamination in
advance" which runs tape through the notch.
TIP
The tape support plate of 32mm or larger ZS feeder does not have notch, only the edge delamination is available.
