of the parts: shutter moving parts,
ratchet wheel section, bottom side of the
upper cover hook and eject path.
Check to see if any component is caught
between the bottom side of the feeder and
the top surface of the bank.
Check to see if the X-reference pin A or B
is not deformed or worn out.
Check the operation of the reel brake.
Check to see if the cramp pressure is
appropriate.
Check the adjustment value.
(If you happen to give a shock to or
impose any unbearable load on the tape
feeder, check the pick-up position.)
Check to see if a foreign substance such
as an adhesive substance is not stuck to
both sides of the peel-off slit section, and
clean the shutter section.
Remove dust generated with sliding
operation from a carrier tape.
Clean the delivery roller rubber, retaining
roller and guide roller section.
Clean the entire tape traveling section.
Clean the eject cover, inner guide,
delivery roller blade, blade base and
retaining roller blade section.
Apply grease to the teeth of the wheel.

• Use IPA (isopropyl alcohol) or ethanol as alcohol.
• Use Albania grease as grease.
• If you use an air gun or similar device to blow off dust or other foreign
substance, take care so that any oil mist (oil misted and mixed with air
when blown) cannot be stuck to any part of the tape feeder. It stains the
cover tape, and may cause the tape feeder to rewind the cover tape
improperly.
• Use IPA (isopropyl alcohol) or ethanol as alcohol.
• Do not apply any grease to the delivery roller or retaining roller section.
This tape feeder is a precision device. Gently handle it so that you cannot
happen to give any shock to or impose unbearable on it. If you happen to
impose unbearable load on the tape feeder, or drop it, check the pick-position
again. (The dedicated feeder inspection jig is required to check and/or adjust
the pick-up position.)
