| B0-C8 | Mark detection PWB cannot read the sheet ID correctly | |
| B1-C8 | Mark detection PWB cannot read the sheet ID correctly | |
| B1-C9 | Printer not ready for printing/paper exhausting within the correct time. | |
| B2-E0 | Mechanism control PWB to mark detection PWB communication error. | |
| B2-E2 | Mark detection PWB cannot read the registration mark correctly. | |
| B3-E8 | Transfer speed correction amount exceeds the allowable range. | |
| B3-E9 | Main-scan write position correction amount exceeds the specified range in the mark detection PWB, i.e. paper speed is not consistent. | |
| B3-EA | Sub-scan write position correction amount exceeds the specified range in the mark detection PWB, i.e. paper speed is not consistent. | |
| C0-00 | Controller data parity error. | |
| C0-01 | Controller address parity error. | |
| C0-02 | There is a break in the video interface path, i.e. between the NLP-K PWB and the mechanism control PWB. | |
| C0-03 | The IOT has not acknowledged a transfer request from the controller within the specified time frame. A timeout has occurred. | |
| C0-05 | The sensor located on the NLP-K PWB has detected that the temperature inside the Stampa PC is too high, i.e. over 52 degrees C. | |
| C0-06 | The sensor located on the power control unit PWB has detected that the temperature near the power control unit PWB is too high, i.e. over 52 degrees C. | |
| C0-0D | A command submitted to the IOT has not received a response in the allowed time frame, resulting in a timeout. This is an IOT problem. | |
| C0-0E | A read command from the microcode to the IOT has failed. | |
| C0-0E | IOT read command time-out | |
| C0-10 | The controller has run out of memory (as a result of a memory leak, for example) and it is therefore not possible to send a skip command to the IOT. | |
| C0-11 | The number of skip commands requested by the printer has reached the limit set by the controller. | |
| C0-12 | The video transfer has not occurred in the allowed time frame, resulting in a timeout. | |
| C0-13 | The upstream printer has printed the front page but the downstream printer has not yet printed the back page. The downstream controller has detected a mismatch between the expected sheet ID and the received sheet ID. This error occurs only when the downstream printer is already aligned and no longer searching for the tandem mark. | |
| C0-14 | An abnormal page sequence has been detected during the alignment process. | |
| C0-20 | The NLP-K PWB is at the wrong FPGA version. | |
| C0-20 | Hardware error (APEX chip) | |
| C0-21 | One of the sensors on the power control unit PWB or the NLP-K PWB detected a temperature of over 57 degrees C. | |
| C0-21 | Hardware error (temperature sensor chip) | |
| C0-22 | There is a problem with CAN bus 1 (internal CAN bus). | |
| C0-22 | Hardware error (CAN bus#1) | |
| C0-23 | There is a problem with CAN bus 2 (external CAN bus, PLB). The external CAN bus includes the PLB bus and implements synchronisation of a duplex line. | |
| C0-23 | Hardware error (CAN bus#2) | |
| C0-24 | There is a problem with the communication between the NLP-K PWB and the power control unit PWB. | |
| C0-24 | Hardware error (power control unit PWB) | |
| C0-25 | An IOT command that was submitted has not been acknowledged in the allowed timeframe. | |
| C0-26 | There is a problem with the IOT power state. | |
| C0-26 | Hardware error (IOT power) | |
| C0-27 | There is a problem with the NLP-K onboard diagnostics. | |
| C0-27 | Hardware error (diagnostic) | |
| C0-28 | One of the sensors on the power control unit PWB or the NLP-K PWB has detected a temperature of over 52 degrees C. | |
| C0-28 | Hardware error (temperature alarm) | |
| C0-40 | If more than one of the errors that follow occur, this error code appears to announce multiple errors: | |
| C2-00 | There is a problem with the communication protocol on the dual-port RAM. | |
| C2-01 | NLPi PWB command time-out | |
| C2-20 | CAN1 transmission error. | |
| C2-21 | CAN1 receipt error. | |
| C2-22 | There is a problem with the power control unit PWB. | |
| C2-23 | This is an error from the communication module between the PC and the NLP-K PWB. | |
| C2-24 | This is an error from the communication module between the PC and the NLP-K PWB. | |
| C2-25 | This is an error from the communication module between the NLP-K PWB and the power control unit PWB. | |
| C2-26 | An IOT command has not been acknowledged by the NLP microcode. | |
| C2-27 | There is a bad response from the NLP-K onboard temperature sensor. | |

| C2-29 | The attention light temperature is too high. |
