Anyone know? At least one of our projectors at the Everett has some ghosting. Is this something easy to adjust like it is on the newer Simplexes or is it more complicated?

There is a knob sticking out the front if memory serves below the shutter shaft that sticks out the front from the opional front shutter
the operator manual is online here and details the procedure remember there is a locking screw on adjustment slide below the lens mount

Make sure the ajustment knob Gordon speaks of is in the center of its travel,then set the shutter manually[2 sprocket teeth advanced shutter should cover the aperture]and remove any ghosting with the knob mentioned in Gordon`s post.

Does this E-7 have the oblique shaft?
If so, then ghosting is also the first sign that this gear is going out.
I've got E-7s and have had many of them go, and they all started with ghosting I couldn't get rid of.
Check to see if the fiber gears on shaft are getting u-shaped, getting thin in the middle.
Also look for a lot of greasy, oily gunk building up on the shutter staff.
These are also signs that the gear is going out.

Pay heed to Tony`s post. This is almost always the case. If you replace just the fibre gear on the oblique shaft, the steel gear on the shutter shaft will soon cut out the new fibre gear. Change it too; hell of a job but change it.The only improvement the E7 offered over earlier Simplexes was the movement and they nullified that with that miserable oblique shaft arrangement. The framing carriage had to be put in a different position every couple of days to prevent unequal wear and seating and who the hell wants to do that.

The oblique shaft did offer a quieter projector but the retrofit to a vertical shaft was more reliable
