Question about Office Equipment & Supplies
Yes tape head can be replaced,a humming sound is also caused by loose connection of parts in power supply section and beeping sound is also caused crack or cold solder solder joint of parts in circuit board...Cold solder issues - each
component is soldered into small
holes on the printed circuit board which in turn connects said
component to the
other components. Due to time, heat, use, some solder joints would be
or loose. It is possible that the cold solder is still minimally
(hanging by a thread). When the unit turns on heat would be
generated which would
be sufficient to further loosen up the solder joint to the point it no
provides electrical contact. Jarring the unit creates movement inside
re establish the contact, sometime good enough sometimes not enough.
Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".
hope this may help;

Check Take up reel. May be bad. Check or replace reel sensor. check clutch. If this unit is CCD-TR, you must replace reels table (take up and supply) is very common to crack bab. And clean contacts on flex board connection on bottom of transport, intermittent contact may cause error on sensors job
