SOURCE: why wont it stop

With that style (4400) of projector, this was usually caused by the trigger on the clutch assembly getting gunked up with dirt and/or grease. Assuming you've removed the bottom of the projector and it's now upside down, lens facing away from you, you'll see a large white gear and near the edge of it will be a grey metal sort of trigger. On it may be resting the L-shaped finger attached to a solenoid.

IF you are confident you can operate this safely with power applied, you can do this, ONLY to help pinpoint the location if you need help. Then remove the power again. *If you are not sure, do not apply power.* Using the remote control so you do not have to put your finger near the cycle (forward/reverse) buttons on the projector's side, activate the forward button, with power turned to fan only (or remove the lamp module). You will see the L-shaped solenoid finger jump briefly and the grey metal trigger
may rock a bit as the gear turns around. And in your case, continues.

Disconnect power if you had it on, and look at the little grey trigger. There is a tiny spring on it and it pivots when you press gently on it. What should be happening is that the L-shaped finger gets caught on that grey trigger and stops the rotation of the gear, as the trigger rests in the edges of the gear. When the solenoid is activated, the L-shaped finger jumps up, releasing the grey trigger which can then rotate one cycle. The trigger should immediately have gone back to its resting position so that it catches the L-shaped finger again and the finger holds the trigger which holds the gear(clutch) from rotating.

Dirt and lubricant has gotten in there and the grey trigger cannot return to its position in time. Eventually it may if you let it cycle long enough. The solution? Use some contact cleaner to clean out the gunk from the pivot of the trigger. It shouldn't take too much. In a pinch you can likely use isopropyl (rubbing) alcohol with cotton swabs. Clean away all the gunk you can but be careful not to get the degreaser on other components. Lint free cloth or paper towels around the clutch gear may be helpful.

Now, the trigger should be able to return to its resting position quickly. If not, repeat degreasing- again it usually doesn't take much. Now, put only one (maximum 2 small) drop of very light oil. Consumers can use sewing machine oil. Too much will later lead to the problem recurring.

Now your projector should be cycling fine, though you might have to turn it right side up to judge accurately. If so, turn it over again,power off again and look where the grey trigger and the L-shaped finger contact each other. Steal just a little bit of grease from the large white clutch gear -use some soft plastic piece like a cotton swab shaft so you don't gouge the gear- and apply it to the contact point. This is not absolutely critical but is recommended to avoid excess wear at that point.

Reassemble, being careful to dress (put inside the housing) the wires so they don't get pinched. Do not over tighten the body screws. If you like you can e-mail me at bytebackkw@yahoo.ca and put "Projector" in the subject line.

SOURCE: projector just keeps cycling through the slides and wont stop, why?

I just spent 20 minutes writing up the solution and because I wasn't logged in, it dumped my post! So, IF you are still in need of a solution, you can e-mail me at bytebackkw@yahoo.ca and I'll post it here again. If you have already got it fixed I won't bother spending another 20 minutes re-writing!

SOURCE: Kodak Carousel 600 Projector - mechanism stops with slide out

Open the back up and spray just a LITTLE bit of WD-40 into the cavity where the bit of spring emerges from the grease covered cam shaft. This will loosen up the grease that has dried up. It may take up to half an hour to work on the grease. If things are improved but not perfect, repeat. If any WD-40 spills out, mop it up with Q-tips and especially avoid the rubber belt.

Please do NOT advance things manually ans especially don't pry apart any of the plastic or metal cams on the cam shaft in an effort to correct the timing. You will put it out of waht and it will take a whack of time and/or an expert to get it back in whack!

SOURCE: My slide projector is advancing the carousel

either the switch terminals are making a constant contact, or the advance solenoid is shorted on. you'll have to take the control panel apart to see if the switch pieces are touching. if not, you'll have to either find the short or take it in for repair.

How do i turn off auto focus?


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.

Why does autofocus keeps moving in and out on some slides


The autofocus system isn't really "autofocus". It is a measuring system - you manually focus the first slide, which sets the distance from the front of the slide in the gate to the back of the projection lens. By the focus motor moving the projection lens, subsequent slides will maintain that same distance. Continuous focus adjustment suggests that:
1> The curvature of the slide is changing because of the varying heat absorption rate of the transparency.
2> The autofocus system is out of calibration.
3> The autofocus system has a bind (it is being restricted from free operation).
About the only thing a user can do is to make sure ALL slides are oriented the same way in the tray. Beyond that, you will need a service manual and 2 or 3 specialized tools. Parts and tools can be purchased from: www.micro-tools.com

Good Luck !! jim

Dirt or dust accumulation can retard the gear mechanism. If you get Canned Air at WalMart, blow out all open areas and see if you can dislodge the material collected inside.

Rollei 35A slide projector - halogen lamp problem


Most all projection lamps of 1970 vintage are still available on the internet. There should be a 3-letter code on the lamp. Try using Google to search that lamp code. There are multiple vendors in the USA that have an amazing inventory remaining. Good Luck !! Jim

I have a 760 H Carousal projector which will nor advane the tray to the next sidle. Souation?


If your projector neither advances or reverses the slide tray, then you most likely have a broken "link". This "link" connects the slide change solenoid to the slide change mechanism. Over time this part becomes brittle & cracks, rendering slide change non-functional. This repair needs to be made by an authorized repair dealer.

Non stop continuous slide tray advance


You didn't specify a model of KODAK Slide Projector.... but the problem you describe is usually caused by excessive wear of the slide change mechanism, inside the projector. This repair is best performed by an Authorized Repair Dealer.

Autofocus


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.

Autofocus


the only way to do that is disconnect the red, black and grey wires from the autofocus switch assembly, but you have to take the projector apart to get to it. if you do, it's on the bottom right side (facing the front of the projector) of the lens.
