4 flashes usually indicates trouble in the vertical circuits. Replace the Vertical output IC and the bypass 220mf Cap. to insure reliability. I don`t know about not hearing the relay click, you may have just blown the power fuse or also may have to troubleshoot the the power supply. ------ Eagle2

# LED Flashes twice every few seconds - The Printer cannot detect the Interconnect Cable. Try the following:

2 If the Interconnect cable is connected correctly and the LED continues to flash twice then replace the Interconnect Cable
LED Flashes 3 times every few seconds - The Printer cannot
