Brother MFC-J1010DW 16 ppm Wireless All-in-One Color Inkjet Printer with Duplex and Mobile Device Support ERR-49 Error Fix: Machine Error 49 — Print Head Temperature Error

Error code ERR-49 on the Brother MFC-J1010DW 16 ppm Wireless All-in-One Color Inkjet Printer with Duplex and Mobile Device Support means: Machine Error 49 — Print Head Temperature Error. Machine Error 49 indicates the print head has exceeded its safe operating temperature. Brother inkjet print heads have a built-in thermistor that monitors temperature during operation. Excessive heat can be caused by sustained heavy printing (large photo prints or many pages continuously), a partially clogged print head that causes the heater elements to overwork, or high ambient room temperature. Allow the printer to cool down for 15-20 minutes with the cover open. Make sure the ventilation openings on the printer are not blocked. Reduce the print duty cycle — avoid printing more than about 50 pages continuously. If this error occurs frequently during normal use, the print head may be failing and need replacement.
