F-100 Won't take any shots

try turning the camera off to load
when loaded turning on should take it to the counter for no 1 film shot

The lens you are using has the aperture ring set to something the camera cannot use. Simply turn the aperture ring to the largest number, usually a 22 or 32. Lock that ring if there is a lock and the fee should be gone.

Is the ERR blinking, and is there an additional blinking E on the display? If so, the film is not loaded properly.
The film is supposed to advance all the way to the take-up spool upon loading. The camera then "rewinds" one frame at a time as you take pictures. This way the camera knows exactly how many shots are left on the roll. Also, if the back is accidentally opened, the shots already taken are already in the can and won't be ruined.

Try cleaning the battery contacts and see whether the battery reads full with no film in the camera.
If problems persists, feel free to reply to this post and give any additional details.

Mamiya RB67 Pro SD that is new to me. loaded the film correctly took the first shot. But, the film won't advance. What am I doing wrong?

The E means that the film isn't being loaded in properly. Reloading the film properly should fix the problem.

A few things to consider:
-Loading: Make sure you are not over loading the film before you start to shoot. I have sometimes turned the film advance too many times and end up cutting down on the amount of usable film.
-Are you loading the film in a dark area and careful to close up the back just after it has started to load to avoid exposing it?
-Shooting: Are you metering properly when shooting? Obviously underexposed images won't develop. You should consider a hand held meter.
-Shooting: Are you advancing the film more than it needs to be after you take your shot? Watch the film counter and feel for that click as it hits the next frame. I have advanced past the next shot many times by accident.
Hope that helps, Matt

remove the battary and the film,the clean the contcts of the bat and bat comparment, and put the battary then operate camera without film.finding it normally operating for 10-20 clicks,put the film and try

Turn the camera on. Open the back. Insert film, pull it across to the red mark. Close the back.

Camera should load automatically.

You can get the manual at http://www.butkus.org/chinon/nikon.htm

There are two conditions under which a blinking "H" will appear in the
LCD panel: (1) when the film has been loaded incorrectly or (2) when the
camera's self-test process detects an internal malfunction. If a
blinking "H" indication appears, perform the following operations in
attempt to resolve the situation:

1. Rewind and remove the film using the rewind button, then remove the
battery to clear the memory.

2. Clean the contacts at the base of the battery compartment with a
clean pencil eraser to ensure proper contact between the camera and
battery.

3. Replace the battery, power the camera back up and operate it as if
it had film loaded, pressing the shutter release.

To get rid of the pesky fEE just set your lens to f22 or f16 ( depending on what lens you have ) and that is all. You might also want to lock this setting in ( if it is a Nikon lens then the lock is on the side just above the lens aperture ring.
