DSI Paper tape reader service manual/schematic needed
Hi everyone, I purchased a DSI NC2400 paper tape reader/punch and while the punch section works perfectly the reader has a problem. Basically, the reader just won't start. It won't respond to a DC1 in remote mode and won't start to read & copy a tape in local mode. When you press the read button, the read LED lights for less than a second & goes out and the read head never moves tape. I will revisit troubleshooting it next week but I figured I would see if anyone had a service manual or schematic for it. I would gladly pay for any scanning/copying costs Thanks, Jeff
When we restored the Univac 1532 I/O console the very first problem was that it would not advance the paper tape through the reader. Turned out to be deteriorated rubber on the pinch roller / capstan assy. After having the rubber replaced and realigned all was well. We sent ours to http://www.terrysrubberrollers.com/ He did a good job.

Jeff, What are the dip switch settings inside? If may be setup wrong. They are a very flexible reader and it may be waiting for terminal commands. The 2400 can have an external terminal setup to control it. corey cohen uǝɥoɔ ʎǝɹoɔ

Hi Corey, I have the operations manual so yesterday I checked and the proper dip switch is set for remote operation which means a DC1 command (Ctrl Q) should turn it on when it is online and the remote operation indicator is lit. Even with a problem in that area, it should still be able to duplicate a tape offline directly to the punch so I think I have an actual bug. I will have more time next week to reseat any socketed chips, connectors, check all voltages, etc. Thanks for the reply! Regards, Jeff
