10. Troubleshooting Message "Internal cooling fan is active." "Self checking..." Cause Solution Large print runs will cause the machine's interior to heat up, triggering the cooling fan. The fan will emit noise, but this is normal and the machine will be operable while the fan is running. The amount of paper that can be printed and the total operation time until the fan starts running depends on the temperature of the location at which the machine is installed. The machine is performing image adjustment operations. The machine may perform periodic maintenance during operations. The frequency and duration of maintenance depends on the humidity, temperature, and printing factors such as number of prints, paper size, and paper type. Wait for the machine to resume operation. When There Is a Problem Scanning or Storing Originals Message Cause "Cannot detect original size. The machine failed to detect Select scan size." the size of the original. Solution • Place the original correctly. • Specify the scan size, and then place the originals again.
