Printer status word 2Bit0 Throat Open—The throat of the printer is open.1 End of Forms—Printer is out of forms.2 Cover Open—The cover of the printer is open.3 Enable/Disable Switch—Switch is in disable position.4 Over Temperature—The printer has detected an over temperaturecondition. When this condition occurs, the 24 volt printer power dropsand the other status bits are no longer valid.5 Forms Jammed—The printer was issued a skip or space command and nopaper motion was detected.6 Zero7 Zero8 Printer Check Light—Read forms parameter and examine bits 0-7of the diagnostic status word to determine cause of error condition.9 Hammer Check—The attachment detected a hammer on when notexpected. When this occurs, the 24 volt printer power drops and theother status bits are no longer valid.10-15 Coded Error Status—These bits are binary coded error informationas follows:17-26 GA34-0003
