Illustrated Parts Breakdown (IPB)

This Illustrated Parts Breakdown (IPB) Manual contains the information necessary to locate and identify

assemblies, sub-assemblies, and specific parts of the 1800 Overhead Projector.

Part Numbers

All components available on a replacement basis are listed with their 3M identification number. The

parts identification list opposite each illustration provides the description adequate to identify

components. If the component is available only as part of the next higher assembly, the description

column provides the next higher assembly description or identification number.

Locating and Identifying a Part

If physical appearance and general location of an item are known:

1. Use the IPB Section Titles to help determine which assembly or sub-assembly includes the item.

2. Refer to the view for the assembly or sub-assembly and locate the item on the exploded view. Match the part

callout number to the corresponding number in the parts list.

3. Parts shown inside a dashed box can only be ordered as an assembly. Any part or mounting hardware shown

outside the box is not included with the assembly.

bottom panel of the projector. The Machine Identification

Plate is divided into the following components:

1. Product Name: The specific version number of the

projector.

2. Model Number/Alpha Code: The series number of the

projector followed by a three or four character alpha code

identifier. The Alpha Code indicates the design level,

specific product characteristics, power cord or

distribution specific to a country.

3. Lamp: The electrical rating of the lamp.

4. MFG Code: The MFG Code indicates the year and

quarter the projector was built.

5. S/N: The serial number assigned to this projector.
