17535 Exposure Head HEAD: all retries failed on chnl 1 All Serial communications between the head and the MPE has failed. The exposure head to backplane (EH-BP) cable should be checked. The exposure head's digital board should also be checked (parameters stored in EEPROM must be restored if the board is swapped). Check that the board has +5V. The MPE may also be faulty. The Platesetter may recover automatically from this error, although it would be best to reboot.
