9.1 Replacement of Squeegees
When the squeegee edge is worn out or deformed by solvent, etc.,
replace the squeegee with a new one to avoid any hindrance in
printing.
• Loosen the squeegee anchor bolt and detach the squeegee.
• Attach a new squeegee as shown in Fig. 5A37 and tighten the
anchor bolt. At this time, be sure to push Plane A of the squeegee
against the flat surface such as a surface plate and tighten the bolt
evenly without any warpage.
• After tightening the bolt, put the edge against a flat surface to
confirm that straightness is secured without any clearance.
The confirmation should be made with the squeegee pushed
against the surface plate at 60° (fixed).

(b) It is advisable that plane A should be polished with the
squeegee being mounted to secure the straightness of
the squeegee for good printing.
Especially, it is effective to print fine-pitched patterns and
keep the coating of the printed patterns in accurate
shape.

9.1.1 Adjustment of Squeegee Head Height
Adjustment Procedure
(1) Loosen the wing and stopper nuts.
Stopper Nut
Wing Nut
L
(2) Adjust the pushing distance by changing Dimension L (the
distance between the upper end plane of the ball bushing and
the lower end plane of the stopper nut).
The pushing distance of the squeegee against the screen is set
to "1.0 mm". (Factory-Adjusted upon Shipment)
When the stopper nut is turned once clockwise, the pushing
distance becomes shorter by 1.0 mm.
Turning the stopper nut once counterclockwise makes the
pushing distance longer by 1.0 mm.
Figures in brackets show the dimension L when the
following metal squeegees are used. If other types of
squeegee are used, consult with our Marketing Dept. or
agent.

9.1 Replacement of Squeegees
(3) Open the "SEMI-AUTO OPN." window (submenu) or the "Print
Block" tab sheet of the "MAN. SUB-SYS" window (submenu)
and push the squeegee against the P.C.B. located in the printing
section.
Refer to the above table and check the relation between Dimen-
sion L and the pushing distance.
(a) When the rubber squeegees are worn out, the push-ing
distance becomes as short as they are worn out. There-
fore, it is required to change the rubber squeegees
before the pushing distance is changed greatly (in the
range of 0.5 mm or less).
(b) The rubber squeegees can be ground to be re-used. In
this case, the total of the dimension (grinding) is limited
to "1.5 mm" (when the maximum pushing distance is
"0.5 mm").
When the total of the dimension (grinding) has become
"1.5 mm", be sure to replace the rubber squeegees with
new ones.
(c) When the rubber squeegees are ground to be re-used,
lower the location of the stopper nuts according to the
dimensions of the ground rubber squeegees (the squee-
gees that have become shorter after grinding) so that
the same pushing distances can be kept.
