1. Machine Overview
1-1. Overview
Make advanced adjustments to this projector in a clean environment with minimal dust and positive pressure. This section provides the advanced adjustment procedures needed to maintain a high quality projection image. There is a specific order that adjustments are to be made and specific tools needed to complete each adjustment.
Important
Only complete advanced adjustments to a projector when the machine settings fall outside of the allowable tolerances for that adjustment or when instructed to do so by another procedure.
1-2. Machine Identification
To avoid incorrect adjustments or part replacements, verify the model and version of the projector prior to making any adjustments or repairs.
Different versions have unique adjustment requirements. The serial number for the projector is located on the machine identification label on the bottom of the projector.
1-3. Cleaning
When cleaning any components of the light engine, extreme care must be taken. Use only soft, dry, clean, Chamois Swabs (Part number 78-8118-3302-5) to clean reflective surfaces. No chemicals should be used on any surface.
Important
Use extreme care when cleaning any optics device. Special coatings can be scratched very easily.
3M™ Multimedia Projector MP7770 Machine Overview
2002, 3M IPC. 1-2
1-4. Safety
Read and understand all safety procedures before making any repairs to the MP7770 Multimedia Projector.
Note
When
any work is being carried out on the device, the mains cable must be disconnected from the mains supply. Only service personnel may carry out service work. For any repair regional and corresponding national regulations are to be followed.
Up to 30.000 V may be incurred when the lamp is ignited; lethal hazard!
An isolation transformer has to be used during any service to avoid possible shock hazard, because of not protected live parts on opened device Eye damage may result from directly viewing into the lamp The lamp is very high temperature and high pressure during operation. Cool down, before opening lamp cover and handling. Wear special protective glasses. Never switch “ON“ without the lamp (high voltage an lamp wiring, 25-35 kV).
1
1. Service and repairs may only be carried out by well-trained personnel. Regional and national regulations concerning the execution of repairs have to be observed.
2.
O
perate the unit with mounted protection plate only (item 1) for protection against possible lamp explosion.
3.Put the unit on an antistatic and hard-to­ inflame support only.
4.
Cables around power supply and lamp are under high tension.
5. Take care not to touch the lamp base when replacing the lamp. It is extremely hot and may cause burns to the skin.
Allow the unit at least 5 minutes to cool down.
