Hi everyone !

I am a french computer sciences teacher and I get an ASR33. I succeeded to clean it and made work well the printer, keyboard and puncher. I have a problem with the reader and so I am looking for someone who could help me.

I cleaned the reader, tested all the contacts. I plugged it. The magnet and the feed wheel are working well and the tape go forward but nothing is printed except some O and ? regardless which is punched of the tape. More, they are not regularly punched. The contacts are good from the reader pins to the distributor disc. So i don’t know what i can do now.

An idea please ?
