Question about Sharp AR-M162 All-In-One Laser Printer
Reads H4-00 Call for Service
H4-00 means heat roller low temperature detection. It usuallly caused by 3 things :
1. The machine hang : You simply reset the error code by pressing : # * C * then input 14 then start.
2. If the error still displayed, open the side cover, feel the fusing unit ( don't touch, it is hot ), if the
fusing unit feels cold then the problem is the heater lamp ( inside the upper heater roller,
connected with anti heat cable and big connector ), you should replace it.
3. If the fusing unit feels warm or hot then the problem is the thermistor ( connected with small cable
and connector ), replace it.
