Exactly what was needed to assess the product - excellent value and great service
 ;
Nice to have the service manual for the Sony DCR-TRV345E now. The document is of excellent quality.
;
MACKIE HR824 26 pages English-only Service Manual contains:
1) HR824 technical overview with the description of front and rear panel switches.
2) HR824 specs
3) Block Diagram
4) Wiring Diagram
5) Packaging management
6) Spare part & final assembly list (for PCB rev A and B) + exploded view
7) Test Procedures (where, how to measure voltage...) including Test Point diagram on the PCB.
8) IC and Transistor charts.
Excellent guide: very clear, good scan quality enabling us to print readable diagram :-)
Note:
Mackie HR824 make extensive use of surface mount devices (SMD). Service on the HR824 must
only be undertaken by experienced service technicians with the right tools, experience and patience to perform surface mount rework when needed.

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 :)

I was very pleased with the service provided and was surprised at how good the quality was of the manual. I thought it may be a third generation copy or so, but it is as good as the websites that charge 3 times this much. I repair some electronics for family and friends without charge, so this is perfect for me. Thank you very much.

5. SERVICE REMARKS
5.1 Handling The Drum 1. Never touch the drum surface with bare hands. 2. Store the drum in a cool dry place. 3. Always wear gloves when cleaning the drum. 4. Prime the drum with setting powder only when the cleaning blade, cleaning brush, and drum are replaced as a set. 5. Never expose the drum to light for a long time. 6. Always keep the drum in the protective sleeve when inserting or pulling the drum out of the copier. 7. Drum conditioning is necessary when a new drum is installed. In addition, it should be done at the following times: a) When image density is reduced due to overexposure of the drum. b) After cleaning the drum. c) When the drum is lightly scratched. 8. Before inserting or sliding out the drum, the cleaning unit should be removed to avoid drum damage. When pulling out the cleaning unit, press the drum shaft slightly to the left. 9. Return used drums to the distributor according to standard procedure. 5.2 Charge Corona 1. Do not use emery paper to clean the corona wire; this abrades the wire coating. 2. Do not touch the corona wire with oily hands. Oil stains may cause white bands on copies. 3. The corona wire height should be adjusted only when a) the front end block is replaced. b) the drum charge current is uneven. 4. Make sure that the corona wires are correctly positioned between the cleaner pads. 5.3 Erase Lamp 1. A narrower lead edge erase margin increases the possibility of fusing jams. The margin should be at least 1.0 mm.
