5 Encoder Card Refer to the “Test Page” again. The current
Temperature is the ambient temperature at the
encoder card in degrees celcius. Printing slows to
prevent overheating. Overheating can cause
excessive ink flow from the print cartridges. The
normal operating range is from 16 to 32 degrees
celcius. If the Current Temperature indicates
“Thermal Sensor Not Installed”, check the
printhead cable connector J10 at the system
board. Also, check the connector at the encoder
card. If the problem continues, replace the system
board.
