• If the cassette feels “tight”while performing operation

 

shown (see Fig. 2), the tape may be jamming due to

 

“ridges” formed in the winding of the tape (visible

 

through the center window). These may be removed, in

 

most cases, by fast winding of the cassette from one

 

end to the other and back again.

• Use only well-known brands of tape. Avoid use of C-120 cassettes.

Furthermore, do not expose cassettes to direct sunlight, dust or oil, and do not touch the tape surfaces.

HEAD CLEANING

The tape heads, pinch roller and capstan require periodic cleaning. This removes particles of the metal oxide coating that wear off the tape and accumulate on these

parts and impair performance. Switch off the power, press the Stop/Eject key to

open the cassette door, and press the Play key. Clean the tape heads, pinch roller and capstan with a soft cloth or cotton pad dampened in isopropyl alcohol or special tape head cleaner.
