Note:
The following requirement is a final functional check to assure adequate clearance between type
pallets and ribbon guides and is made with a type carrier installed. Too much clearance between pallets
and ribbon guides may cause ribbon smudge on the paper, making it difficult to make the PAPER
POSITIONER adjustment.
Requirement (B)
There shall be a minimum of 0.010 inch clearance between the closest pallet and the ribbon guides.
To Check
Seat all pallets against the rear surface of the front flange of the left sprocket. Position a 0.010 flat
gauge against the ribbon guide and rotate the type carrier one complete revolution by turning impeller
gear by hand clockwise. Repeat the procedure with the other ribbon guide.
To Adjust
Recheck the following adjustments:
