When the alarm light is blinking what other lights are on. This is the fatal error code with the printer.
Remove the ribbon. if still not moving smoothly unit needs service. 3 year warranty on this unit brand new.
If you cannot move the carriage back and fourth accross,
there is a seriuois issue. unit requires service.

We swapped out the printer for another one we had in the office that was working. The new printer also got the alarm light. From that we concluded that it was a bad serial card. We swapped the serial card from another printer, and the original printer started working perfectly. Now we just need to find out where we can purchase another serial card, as we have no more 'spares' around here.

Use the IBM proprinter driver for this printer and select IBM in the menu of the printer.
Hope this helps.

Could be 2 things..
First Check close and make sure there are not small bits of paper in the feeding arms rollers etc.. any place paper passes make 100% sure. Second adjust the tension from the feeding arm and make sure the paper path to the printer is clear.
You can also hit it with a few shots of Dustoff
