If you find that the printing is done perfectly, the go to the prior application and try to print a different file. This will help you to check whether the printer is doing its job perfectly without showing the same error.

  • Disconnect all the cords and connections attached to the printer. This step is a must if the error code persists with different software applications and printing.

Step 4: Remove the DIMMs from the printer

  • Turn OFF the printer and remove all the DIMMs as well as the third-party DIMMs from the printer for removing all printing memories.
  • Keep the firmware DIMM and don’t remove it.
  • Now remove all the EIO devices before turning ON the printer.
  • If you find the Code 49 error is resolved, it’s strongly advised to install each DIMM along with the EIO device separately while keeping the power OFF.
  • Now, switch on the power of the printer to start printing once again.
  • If you notice that the DIMM or the EIO device is the reason behind the error, then replace it.
