My slide projector's autofocus is constantly adjusting the focus - it never stops zooming in and out.
It's an old projector, so I was hoping there is a way to disconnect it. There's no switch to turn it off but I figure I could snip a wire.
I'm willing to adjust manually.

To strictly turn off the auto-focus, you have 2 options:
1. Some generations of 5600's have an Autofocus On/Off Switch. If so equipped, move the switch to "Off".
2. Remove the bottom cover. Locate the auto-focus motor and clip on of the wires that power the motor.
If repair is what you want to do, the problem becomes more complex and expensive! You will have to contact: www.micro-tools.com
You can order the 2 special tools, instructions and any other parts you need from them. When Kodak stopped supporting the slide projector business, micro tools bought out the remaining repair parts.
I can think of three possible reasons for the continuous focus adjustments: the autofocus system may have a bind; it might be in need of calibration; or the curvature of the slides keep changing because of the varying heat absorption rate of the transparency.
Unfortunately, aside from making sure that all the slides are in the same orientation as the tray, there isn't much that the average user can do to correct the continuous focus adjustments.
The lens focus ring is set and calibrated by the manufacturer using precision instruments like MTF testing benches and many other specialized tools, thus making it difficult for end users to perform any sort of manual adjustments. I would get in touch with the manufacturer to see if either repair or replacement would be a viable option.
The auto-focus system in Kodak slide projectors is really an auto-measurement system: One set manually, the system is supposed to maintain that distance on all subsequent slides. Correct orientation of the slides is that they are all placed in the slide tray in the SAME direction (the matte side of the transparency facing toward the screen). The measurement is from the FRONT of the slide transparency to the BACK of the projection lens. REPAIR calibration of the system requires 2 special tools: a RANGE SLIDE and a TARGET SLIDE. These tool slides and the calibration procedure SHOULD be available from: www.micro-tools.com They purchased all remaining repair parts from Kodak when Kodak stopped supporting slide projectors. Good Luck !! Jim
The auto-focus system requires adjustment / set-up with special tools if the auto-focus no longer functions correctly. Before ordering the tools from: www.micro-tools.com
check a couple of things:
1. Is the "Auto-Focus on-off Switch" in the "ON" position?
2. Put a slide that is as dark as possible in the slide gate. Power on, lamp on. Look down into the gate, on the front side of the slide. You should see a "S"-shaped light near the center of the slide.
If you have validated both of the conditions above, then I would contact my friends at micro-tools for the special tools. They should be able to provide you with adjustment instructions.
Good Luck !! Jim
There is nothing wrong with your slide trays. Your projector needs an adjustment to the cycle contact assembly. The constant cycle mode is a dead-giveaway. You need to take the projector to an Authorized Repair Dealer for this adjustment. Should be relatively quick - - it takes longer to get the case apart than to make the repair!
Hi- I'm not at all familiar with this model so won't suggest a particular fix. However, in general, you may find some gear or other mechanical linkage, or perhaps a spring holding a gear in place has slipped. That caused the same symptm in some old Kodaks I know of. If you cannot figure it out AND you don't mind not having autofocus, you could disable AF. Inside you will find some sort of small light bulb. Disconnecting one lead will turn off that light and prevent AF from doing anything. If you end up taking that route, make sure you load all your slides in with the emulsion facing the same way (that's the less shiny side of the slide). This will reduce the amount of focus difference between slides.
Well, that's a general statement. If you are looking to have the image look like a HDTV then you have the wrong impression of the projector's capabilities. At 800x600 resolution you will get a "good" but not great image especially if compared to a tube tv or plasma/lcd. If the graphics are sharp when you press the menu key then you probably do not have an issue. If, however, even the graphics are blurry, then you have to manually adjust the Grey outer focus ring on the lens. The inner ring will adjust the zoom. Hope this helps.
