5.4.4 Repairing The Microcassette Tape Drive Unit
Before repairing the microcassette tape drive unit, check the following:
1) Check the read/write and pinch roller for dirts.
2) Exchange the microcassette tape for known good one and test to make sure malfunction is not
due to a damaged tape.
3) Make sure that the lead wires from the mechanical section are perfectly soldered.
4) Examine the error message on the LCD panel to find whether the trouble is a directory-related
problem. Tapes written by other computers may contain no directory and cannot be read by
this computer.
Problems 1) and 2), above, are interrelated so that both the checks should be performed at the
same time.
