	Trendsetter 3230 (TS4 Version)	Priority = Next Failure
	Trendsetter Spectrum	Reason = Reliability
	Proofsetter Spectrum	Release date = 7 July 1999
	VLF Trendsetter
	VLF Platesetter
	Renaissance Scanner

Machines affected	All
Component	Encoder
Problems	Vacuum plugs on the drums cause reflections Encoder is unreliable
Solution(s)	On next service visit, install decals 74-3236A on all drums with vacuum seal discs behind the encoder disc. Align and clean encoder, if it fails. If still failing, replace Encoder Block assemblies 32-3011B and 32-4047A with new version 32-4047B.
Parts needed	Kit 05-0122: 32-4047B Encoder Block Assembly 74-3236B Anti-reflective decals 74-3236A Assembly drawing for placement of decals 73-3289A 73-0106A
Procedure	On next service visit, install decals 74-3236B on all drums with vacuum seal discs behind the encoder disc. Anti-reflection decal installation procedure If encoders fail, replace either 32-3011B or 32-4047A with 32-4047B: only after procedure 73-0106A, Optical Encoder Alignment Procedure, has been done and has indicated encoder failure OR if the encoder has been aligned with 73-0106A within the past 2 months and when second failure occurs, 73-3289A Optical encoder cleaning procedure has been fully performed
Action Required	See Procedure section above.
