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.

Take up the cover tape until all slacks on the cover tape removed.
During this operation, be careful not to be winded your fingers in the roller unit while taking up the cover tape.

Also, the taking up cover tape can be performed by reattaching the feeder after detaching from temporary tape set station.
