8mm Film Projector

Product details Experiment highlights Questions about experiments

Questions about experiments: Check the following if your experiments run into problems.

Q1

The lamp does not light up.

Are the batteries inserted properly? Use new batteries, insert them in the correct direction, and make sure they are the right type.

Q2

The image is dark.

The light is produced by an ultra-bright 1 W white LED powered by three AA batteries. It has low power consumption and displays white very clearly. The brightness is different in quality from a large projector with an AC power supply, so the room should be as dark as possible.

Q3

It's out of focus.

Stop on a bright, clear frame and bring it into focus. Hold the front ring of the projection lens and rotate it to move the lens in and out until you can see the image sharply.

Q4

I can't see moving image clearly.

Be sure to leave the top section of film a little loose when setting the film in place. (See 1-2 in the instruction manual.)
If the film is tight, the image will not settle down.

Q5

I can't see moving image clearly.

Check that the tabs on the part that holds the film down are firmly catching the film perforations.

Q6

I can't see moving image clearly. The perforations (holes in the film) are not aligned.

Is the film you are using Single 8 or Super 8?
If it is Double 8, it will not feed properly unless you change a few parts.
Change three parts to the Double 8 versions. (See 4-1.2.3.4 in the instruction manual.)

Q7

The frame is off.

Adjust the framing knob until the image is framed correctly. (See 2-4 in the instruction manual.)

Q8

I want to use a large reel.

The empty reel we supply is a small 7.5 cm-diameter reel (for 50 feet). If you have larger reels, you can use them up to a size of about 9.3 cm (for 100 feet). If your edited film is longer than 100 feet, you will need to cut it into shorter segments.

Q9

The film rewinds upside down.

There is a mistake in Figure 2-5 in the instruction manual. We apologize for that. When rewinding, set film on the reel so that the perforations (the holes in the film) are toward you. Note that even if the film is rewound backwards, it will project fine on this projector.

Q10

The film does not go through the frame border.

It is difficult to feed film that is bent at the front or bends toward the light source in. If the film is curled, try curling the tip slightly toward the front (toward the lens).

Q11

Film feed is irregular.

Make sure there is enough play in the film between the sprockets and the lens. If the film is too tight, the frame will be unstable, creating blur. Frames can also skip on film that has hardened after long years in storage. (The projector is shipped set up for single 8 or super 8. If you have double 8 film, change out the necessary parts.)

Q12

I've edited the film, but now the film feed is jumpy at the edited part.

If cellophane tape is used, frames skip in an edited section. Use special splicing tape to make sure frames feed properly.

Q13

I've edited the film, but now the film jams at the edited part.

There may be wrinkles in the tape you used or bits sticking out from the sides of the film that are catching. If something like this is happening, remove the tape and redo the edits.

Q14

Film does not rewind.

The rewind reel axis can be put at different angles depending on reel size. Belt tension is lower at the bottom position, so put the axle at the upper position if you are using the provided rewind reel. If you are regularly using the reel at the bottom position, replace the belt with a smaller rubber band (No. 14) to keep it steady.

Q15

I want to replace the film partway through.

You cannot change the film while the projector is running. Run the film to the end, then rewind it onto the rewind reel. If you need to remove the film partway through due to film problems, remove the four front screws holding the frame border in place and remove the film.

Q16

The light source is dim.

Check the orientation and type of the batteries. The LED may also stop emitting light if the voltage from a rechargeable batteries, such as NiCd batteries, is too low.

Q17

The film broke while projecting.

The adhesive on edited areas of old films can weaken and break. Align the broken ends of the film with the film editing tool and redo the splices with splicing tape.

Q18

The projector is damaging the film.

If something is stuck somewhere on the film travel path, it can scratch the film. Remove dirt and dust before projecting films.

Q19

The image is upside down.

The film is traveling the wrong path. Rewind it on a different reel and then project it.

Q20

I want to stop the film to project a single frame.

The projector uses an ultra-bright white LED as its light source. Since it is not as hot as a light bulb, the film will not be damaged by the heat if you stop the film while projecting.
