Interface cables compatible with this unit are USB 
and parallel cables. Check which type of cable is 
supported by your computer, and then purchase 
one of the following cables accordingly:
USB cable
Shielded twisted pair cable (2 m (6 feet) Max.: high-
speed transmission equivalent)
Parallel interface cable
IEEE 1284 - Shielded type bi-directional parallel 
interface cable (2 m (6 feet) Max.)

Check if the interface cable is securely plugged into 
the connectors of the unit and computer. It is also 
advisable to ensure that the connector pins are not 
bent.

Reference:

See "CONNECTING THE INTERFACE 
CABLE" in the Operator’s Manual for more 
details on interface connection.

If other USB peripherals are connected through the 
same hub, disconnect them to see if the problem 
still exists.

If the USB cable becomes disconnected, even only once during 
the unit's operation, then printing and scanning may be 
disrupted.
If this occurs, check the USB cable and ensure that it is 
securely connected, then restart the computer.
