BB3000 carriage speed

[ajvieirajr]

hi friends, am a Brazilian technician. I was called to fix a very old BB3000, must be about 15 years of use. When I arrived at the client, the equipment was not working. I found that the flat cable carriage was damaged. I replaced the part. The equipment is working again, but the speed of the carriage return was very fast and very strong beat. I replaced the KBIC but I can not adjust the speed of the carriage. I have not needed to adjust the tension. I checked the wiring and it is ok. Has anyone had this problem?

I know I'm very late to your question and you probably figured it out by now.

Doesn't the BB3000 have a two speed selection for the carriage to change the notching "pitch" when cutting the book spine?

Maybe that control or it's circuit has gone haywire.
