Rollei P3800 Slide Projector. Hi my problem is that the autofocus motor just runs and never stops?
I found a discussion thread where other users faced similar issues with Rollei projectors.
Rollei 6x6 projector focus - Accessories - Photo.net
I have not accessed the manual for this. I can offer some general suggestions based on common troubleshooting steps:
Check for Obstructions:
Inspect the lens and autofocus mechanism for any physical obstructions or debris. Sometimes foreign particles can interfere with the motor's operation.
Ensure that there are no bent or damaged parts within the autofocus assembly.
Electrical Connections and Contacts:
Verify that all electrical connections are secure. Loose or damaged wires could cause erratic behavior.
Examine the contacts between the autofocus motor and the control circuitry. Corroded or faulty contacts might lead to continuous motor operation.
Sensor Calibration:
Some projectors use sensors to detect focus. If these sensors are misaligned or malfunctioning, it could cause the autofocus motor to behave unpredictably.
Check if there's a calibration procedure in the projector's manual. Follow the steps to recalibrate the autofocus system.
Motor Controller and Circuit Board:
The motor controller circuit board controls the autofocus motor. Inspect it for any visible damage, burnt components, or loose connections.
If you have technical expertise, consider checking the motor controller's components, such as capacitors and resistors.
Manual Focus Mode:
While troubleshooting, switch the projector to manual focus mode. If the manual focus works correctly, it indicates that the issue lies specifically with the autofocus system.
You can manually focus the projector by adjusting the focus ring on the lens.
Professional Repair:
If the above steps don't resolve the issue, consider seeking professional repair services

My scansnap ix500 give me error #0x00044400 when
Right click on the ScanSnap Manager icon at the bottom right of your computer screen, go to "Scan Button Settings"
Then, go to the tab that says Paper. If you don't see it, click on details at the bottom left.
In paper, change multifeed detection to Check Length or None instead of Ultrasonic Sensor.
If this works, then the ultrasonic sensor on this scanner has failed. The only function is it detects if multiple pages go through at the same time by listening to the vibrations. Your scanner can still scan fine without it.
