USB Connection Problems

If the printer connected to the computer via USB is not recognized, check the following items.

The following problems may occur even though the USB connection is recognized.

  • Printing (scanning) is slow.
  • Hi-Speed USB connection does not work.
  • A message such as "This device can perform faster" appears(Windows).

If the above is the case, check the following.

Note

  • If your system environment does not support Hi-Speed USB, the printer operates at the slower speed of Full-Speed or Low-Speed. In this case, the printer works properly but printing (scanning) speed may slow down due to the communication speed.
