3, Check whether the toner cartridge is installed correctly. Re-install the edge and ensure that the sealed tape is removed from the bottom of the cartridge.

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.
