The service was quick and simple, finding the service manual easy and it appears to be the original with colour schematics. It contained the info I was after and so sorted the problem.
I have copied it to CD and attached the envelope to the inside back cover of the owners manual. Good manual and excelent service. Robin Wood, Wood Electronics, New Zealand.

Nice to have the service manual for the Sony DCR-TRV345E now. The document is of excellent quality.

This Service manual is very well scanned and its clean to read, no any anti-theft words that un-english could understand. I got my CCD600 working with this manual and it´s clear shematics :)

Initializing the upper document feed roller When the separation roller starts to rotate, the position of the upper document
feed roller is simultaneously initialized to raise the document stopper
NOTE
Initialization is carried out when the power is turned ON, when documents are inserted and when documents are ejected.
Document feed lever
Switching between automatic document feed and manual document feed is carried out by the document feed lever above the left side of the LCD. During automatic document feed, documents arc gripped between the separation guide and the separation roller. Switching the lever to manual document feed raises the separation guide and frees it from the document. Manual document feed can therefore minimize the possibility of damage caused by pinching between the separation guide and separation roller when feeding documents such as thick-stock paper or photographs. However, because document separation does not occur in manual document feed mode, only one sheet at a time may be loaded. Loading multiple sheets will result in double feed.
Document feed error detection
There are three types of document feed errors which may occur.
a) Feed jam error
When the leading edge of the document is not detected by the document edge sensor (DES) within 15 seconds after the start of document feed, a feed jam error is detected and document feed is terminated.
b) Document extraction error When a document is extracted after document feed has started but befow the
DES is turned on, a document extraction error is detected, and feeding is tcmminated. c) Eject jam/ document too long error When the trailing edge of the document is not detected within one meter of feeding after the document�s leading edge is detected, an cjcct jnml document too long error is detected and fading is tcrminnted. When one of these types of jams occurs, all daln which have been rend and stored in memory [which are not par1 of a page that has already been completely transmitted or copiedi arc crnsed. _ ~~~~~._
