If you will encounter paper jam error message of your brother printers even if there is no paper that jammed inside your printer, there might be a problem with the paper sensor inside your brother printer. This is caused by a scattered ink from the printer head, because this sensor is being placed beside the printer head itself. We need to open the printer and cleaning this suspected sensor with a solution or alcohol. Do not do this if you are not familiar how to do so. It might damage your whole printer. please contact us at 0948-6847-908. we offer home/office service for your convenience.
