Describes the cleaning of the nozzle holder placed in the transfer head.
Tool used: Lint free cloth, air blow gun, baby cotton swabs, cleaning paper, nozzle holder shaft cleaning
tool (N610130890AB)
Time required: 40 minutes per light weight16-nozzle head, 35 minutes per 12-nozzle head, 30 minutes per
8-nozzle head
●The following description takes the 12-nozzle head option as an example; however, the same
Procedure is also applicable to the light weight16- and 8-nozzle heads.
Cleaning parts
Spring for nozzle cushion
(If dust settles, it could cause faulty nozzle cushion)
Inner and outer circumferences of
nozzle holder (If dust settles, it
could cause pickup errors due to
sliding failures)
Spring for holding nozzle clamp
claws
●It holds the clamp claws. (If dust
settles, it could cause nozzle
clamp errors)
Clamp claw (one on either side)
●It directly catches hold of a
nozzle. (If dust settles, it could
cause a pickup or placement
error due to air leak or a
catching failure)
Vacuum filter
●The filter, located in the air pathway, prevents air dust from
penetrating inside of the machine.
(If dust accumulates, it could cause a pickup error because of
delayed timing to switch vacuum at the nozzle tip)
Nozzle holder contact surface
(If dust settles, it could cause a pickup error or affect
placement accuracy due to air leaks caused by the
nozzle holder contact surface that cannot keep in
absolute contact with the nozzle contact surface as a
nozzle is securely fixed in place)
