Brother MFC-J4335DW 20 ppm Wireless INKvestment Tank All-in-One Inkjet Printer with Duplex and Fax ERR-48 Error Fix: Machine Error 48 — Head Cleaning Failure

Error code ERR-48 on the Brother MFC-J4335DW 20 ppm Wireless INKvestment Tank All-in-One Inkjet Printer with Duplex and Fax means: Machine Error 48 — Head Cleaning Failure. Machine Error 48 indicates the automatic print head cleaning cycle could not complete successfully. The printer attempted to purge dried ink from the nozzles but the cleaning mechanism failed or the waste ink system could not absorb the purged ink. This often occurs when the printer has been sitting unused for an extended period and the ink has dried in the purge lines. Power cycle the printer — unplug it from the wall outlet for at least 60 seconds, then plug back in. If the error returns, the internal waste ink absorber may be nearing capacity, or the pump assembly that draws ink through the print head may be clogged. Repeated cleaning cycles consume significant ink. If you have not used the printer in months, the print head may need to be removed and soaked in warm distilled water to dissolve dried ink.
