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

Xerox workcentre 3345 paper jam in tray1
If you've modified one of the trays and still encounter the same error, it's worth checking if there are any obstructions in the paper path or if the default paper type and color settings need adjustment.
Remove Jammed Paper From Tray 1:
First, remove any paper from the Bypass Tray.
Grasp both sides of the Bypass Tray and pull it straight out of the printer.
Next, pull out Tray 1 until it stops. To remove the tray, lift the front of it slightly, then pull it out of the printer.
Check for any jammed paper and remove it.
Also, make sure there's no crumpled paper left in the tray or jammed inside the printer.
If you have Tray 2 (optional), check it as well.
Insert Tray 1 back into the printer and push it all the way in.
Fully insert the Bypass Tray as well.
Confirm the paper settings if prompted.
Try your job again.
Power the Printer Off then On:
Press the Power/Wake button on the printer control panel.
Choose "Power Off" to turn off the printer.
Wait for a few seconds, then press the Power/Wake button again to turn it back on.
Retry your print job.
Replace the Paper Feed Roller (if needed):
If the issue persists, consider replacing the paper feed roller. Refer to your printer's documentation for instructions on how to do this.
If the problem continues, contact Xerox support.
