Before replacing the projection lens
Return the projection lens to the home position before replacing or removing it.
For details on how to return the lens to the home position, refer to the operating
instructions of the projector.
Attention
z
Make sure that the projector power supply is switched off before attaching or detaching the
projection lens.
z
After removing the projection lens, store it safely away from vibration or impacts.
z
Do not touch the electric contact points of the projection lens with your fingers. Dust and dirt
on the contacts may cause contact malfunctions, while static electricity may damage the unit.

Making Adjustments
Correcting the Focus
When the projection lens is attached to the projector and images are being projected
onto the screen, the peripheral focus may be out of focus in some localized areas.
In such cases, use the supplied spacers to correct the focus of these areas, and perform
adjustments so that the entire image is even.
■
Relationship between lens orientation and screen focus
If the projection lens is tilted with respect to the plane of the screen, uneven focus will
result. For example, when the front side of the lens (screen side) is tilted downward as
shown in the figure below (direction of the dotted arrow), the upper part of the screen
will be tilted backward and the lower part of the screen will be tilted forward.

■
Procedure for correcting the focus
Attention
z
Turn off the projector before removing the projection lens.
Note
z
Focus correction requires some technical skill. Be sure to have a person with knowledge of
projectors or a service technician to perform adjustments.
z
Do not touch the surface of the lens with bare hands. Finger prints and dirt on the surface
of the lens will be magnified by the lens and lower the quality of the projected image. Place
the supplied lens cover on the zoom lens when the projector is not in use.
z
The lens is made of glass. The lens could be damaged if brought into contact with or
rubbed against hard objects. Handle the lens carefully.
z
Use a clean, soft and dry cloth to wipe away dust and dirt from the projection lens.
Do not use fl uffy cloths containing oil, water or dust for cleaning. The lens is easily
damaged, so do not apply excessive pressure when wiping it.
Attaching the Lens / Detaching the Lens
For details on attaching or removing the projection lens, refer to the operating
instructions for the projector.

1) Install the projector in the installation location, and turn it on to project an image.
2) Move the lens to its home position.
3) Operate the projector to shift the focus of the entire projected image toward
the front of the screen.
4) Operate the projector to shift the focus toward the screen a little bit at a time until
one of the areas A to D in Fig. 1 just comes into focus on the screen, and then stop.
z
In this state, the “just focus points” of the unfocused areas are positioned just in front of
the screen. The distance between this position and the screen is the correction distance.
5) Insert the spacers between the body of the projector and the lens mounter, as
shown in Fig. 2.
z
Remove the lens mounter from the projector, and insert the spacers in the positions
that correspond to the unfocused areas.
z
The “just focus points” of the areas for which you inserted spacers will be corrected
toward the rear of the screen.
z
Make sure the adhesive surfaces of the spacers face the lens mounter when inserting them.
z
The correction distance is determined by the thickness and quantity of spacers
inserted. Insert spacers according to the correction distance.
(The unit for correction distances derived from the formulas in the following table is millimeters.)
Spacer Color Thickness
Correction distance
during projected image size SD (m)
Clear 0.1 mm SD × SD × 51.5
Black
0.2 mm SD × SD × 103
Cream
0.3 mm SD × SD × 154.5
Correction distance guide: When the projected image size is 1.52 m (60 in.), the cor-
rected distance when one 0.1 mm thick spacer is inserted is 120 mm.
Attention
z
Installing the lens mounter, be careful not to put wiring between the lens mounter and the
projector unit.

Projection relationships (continued)
Attention
z
To prevent blocking of the intake and exhaust vents, maintain clearances from walls and
objects of at least 1 000 mm (3'3") for the exhaust vent and at least 500 mm (1'8") for the
intake vent.
z
Avoid setting up in places which are subject to sudden temperature changes, such as near
an air conditioner or lighting equipment (studio lamps, etc.).
■
Dimensional relationship
For details on the projection distance (L), refer to “Projected image size and Projection
distance” and “Projection distance formulas” in the Appendix.
Note
z
For details on “Projected image size and Projection distance” for projector models other
than PT-MZ770 / PT-MW730 / PT-MZ670 / PT-MW630 / PT-MZ570 / PT-MW530 /
PT-EZ770 / PT-EW730 / PT-EX800, refer to “Setting up” in the operating instructions of the
projector.
Perform the lens position shift within the adjustment range.
Perform lens shift adjustment within the ranges shown in the following illustrations.
Moving the lens outside of the adjustment ranges may alter the focus. The focus may
change when the lens position is shifted out of the adjustment range. This is because
the movement of the lens is restricted to protect the optical parts. Projection position
can be adjusted with the optical axis shift based on the home position in the respective
range.

and horizontal positions of the lens) based on the results of lens calibration. It is not the
