1.1.3 Inspecting the nozzle holding force
Periodically inspect the nozzle holding condition of the leaf springs.
• If the holding force of the nozzle leaf springs is unstable, this may adversely affect the pickup, recognition, and
mounting.
• If the roller lock is loose, this may adversely affect the nozzle holding force.
• If the roller is scratched, this may cause recognition errors.
n
Leaf spring and roller inspection points
Check the following points by removing the nozzle and reattaching it to the nozzle holder.
• The leaf spring has enough holding force.
• With the nozzle attached, there are no gaps between the leaf springs and the rollers and between the rollers and the
nozzle
• No nozzle leaf springs are deformed.
• No screws are loose.
• No rollers are scratched.
