What is an answering machine?

How to Trouble Shoot Telephone Answering Cassette Tape Problems

Telephone answering machines are designed to record voice messages. The machine plays a voice message giving information or instructions to incoming callers. These callers are requested to leave messages that can be retrieved later by the owner of the answering machine. The answering machine then records the caller's response. Cassette-based answering machines store outgoing and incoming messages on audiotapes. A cassette deck records and plays audio signals stored on a magnetic tape. When the answering machine stops functioning, businesses can lose customers and it is sometimes cost-prohibitive to call a repair service. Many times, this answering machine malfunction can be tracked to problems with the cassette tape. When the phone rings, but the cassette does not record the messages, the following steps can be taken to correct the problem.

Step 1. For loose cassette tapes, remove the screws that hold the cassette together and rewind it.

Step 2: If the tape jams, you’ll have to replace that old tape with a new one, being careful while you remove the old tape.

Step 3: For slow moving tapes, clean the heads of the answering machine and the tape path.

Step 4: If the deck stops unexpectedly, or will not stop at the end of a tape, the cassette may be dirty. Clean the machine hubs as well as the cassette itself.

Step 5: If the tape will not rewind or fast forward, check to see if the belt is loose or broken. If the belt is damaged, replace the belt.

Step 6: If the deck will not record, the record/playback switch may be faulty. At this point, you’ll have to call a repair service or buy a new machine. . These are repair suggestions that if taken may solve the problem of an answering machine’s cassette malfunction. However, if after trying all of these suggestions the answering machine does not record or play back, it may be necessary to obtain the services of a professional.
