B504 error Canon Maxify Printers

Certified repair for the canon mb5310 with a error code 5040 due to a broken cable from a possible mishandling of the scanning unit. We were able to unravel the cable and mend it back via a soldering iron. The error is gone but the yellow and magenta is low which will trigger a b504 error because the head will overheat without all the ink. So we need to get ink for it before we can move ahead.#Computerrepairshop #PrinterRepair #printing #Epson #Ittech #TrinidadandTobago #HP #Brother #Dell #Deskt
