Bathy-500
While operating the B500(MF)the printer stopped printing. The system is still transmitting and the depth is still displayed correctly. System parameters can be changed as well.
Answer:
This could indicate some sort of printer failure but their are a couple of other things that could cause this problem as well.
1. Is the CHART set to "ON" as it should be? Cycle the CHART "ON" parameter to "OFF" then "ON" again and depress "ENTER".
2. Is the system being operated on a hot day and is the system in direct sunlight?
The printer has a thermal printhead that uses heat to mark the chart paper. If the printhead reaches a temperature outside of its operating range the printer stops printing. To rectify this problem the unit should be placed in a shady place if at all possible and/or the printer door should be opened to allow the heat to escape.
3. Are there any problems with the paper? Their is an optical paper sensor just beyond the thermal printhead on the platen. If the paper runs out or is not correctly travelling on the platen, the sensor will not allow printing to operate. Make sure the paper is properly installed and that it is advancing on the platen as expected.
4. If the above actions do not fix the problem then a printer cable or component failure is most likely. Check the printer cable at both ends for proper termination. Visually inspect the Printer PCB for signs of a failed component. If all seems okay, power up the unit and verify that the PRN test fails. If it does, replace the Printer PCB.
