DECK MECHANISM ADJUSTMENT 1.Mechanism Alignment Position Check Purpose:To determine if the Mechanism is in the correct position, when a Tape is ejected. Test Equipment/ Fixture Test Conditions (Mechanism Condition) • Blank tape • Eject Mode (with Cassette ejected) 1) Turn the Power S/W on and eject the Cassette by pressing the Eject Button. 2) Remove the Top Cover and Plate Assembly Top, visually check if the Gear Cam Hole is aligned with the Chassis Hole as below Fig. C-2.
DECK MECHANISM ADJUSTMENT Cassette without Tape. Cover the Holes of the End Sensors at the both sides of the Bracket Side(L) and Bracket Assembly Door to prevent a light leak. Then The Deck Mechanism drives to the Stop Mode. In this case, The Deck Mechanism can accept inputs of each mode, however the Rewind and Review Operation can not be performed for more than a few seconds because the Take-up Reel Table is in the Stop State and can not be detected the Reel Pulses. 2.
DECK MECHANISM ADJUSTMENT 4.Guide Roller Height Adjustment Purpose: To regulate the Height of the Tape so that the Bottom of the Tape runs along the Tape Guide Line on the Lower Drum. 4-1. Preliminary Adjustment Test Equipment/ Fixture • Post Height Adjusting Driver Test Conditions (Mechanism Condition) • Play or Review Mode Adjustment Procedure Adjustment Point • Guide Roller Height Adjustment screws on the Supply and Take-Up Guide Rollers.
DECK MECHANISM ADJUSTMENT 5. Audio/Control (A/C) Head Adjustment Purpose: To insure that the Tape passes accurately over the Audio and Control Tracks in exact Alignment in both the Record and Playback Modes. 5-1. Preliminary Adjustment (Height and Tilt Adjustment) Perform the Preliminary Adjustment, when there is no Audio Output Signal with the Alignment Tape.
DECK MECHANISM ADJUSTMENT slowly turn the Tilt Adjustment Screw(C) in the Counterclockwise direction. 5-2. Confirm that the Tape passes smoothly between the Take-up Guide and Pinch Roller(using a Mirror or the naked eye). 1) After completing Step 5-1.(Preliminary Adjustment), check that the Tape passes around the Take-up Guide and Pinch Roller without Folding or Curling at the Top or Bottom.
DECK MECHANISM ADJUSTMENT 7. Adjustment after Replacing Drum Assembly (Video Heads) Purpose: To correct for shift in the Roller Guide and X value after replacing the Drum.
MAINTENANCE/INSPECTION PROCEDURE 1 Check before starting repairs The following faults can be remedied by cleaning and oiling. Check the needed lubrication and the conditions of cleanliness in the unit. Check with the customer to find out how often the unit is used, and then determine that the unit is ready for inspection and maintenance. Check the following parts.
MAINTENANCE/INSPECTION PROCEDURE 2. Required Maintenance The recording density of a VCR(VCP) is much higher than that of an audio tape recorder. VCR(VCP) components must be very precise, at tolerances of 1/1000mm, to ensure compatiblity with other VCRs. If any of these components are worn or dirty, the symptoms will be the same as if the part is defective. To ensure a good picture, periodic inspection and maintenance, including replacement of worn out parts and lubrication, is necessary. 3.
MAINTENANCE/INSPECTION PROCEDURE 5-2) Greasing (1) Greasing guidelines Apply grease, with a cleaning patch. Do not use excess grease. It may come into contact with the tape transport or drive system. Wipe any excess and clean with clean ing patch wetted in Isopropyl Alcohol. (2) Periodic greasing Grease specified locations every 5,000 hours.
