Generally these are very high quality printers but I have had three fan failures on these so far. The fan is running fine but the firmware thinks it has stopped turning. The problem seems to be the tachometer circuit in the fan. These are the three-wire fans we used to see as CPU coolers on Pentium Three motherboards. One fan was made in Viet Nam and the other two were made in Taiwan.
