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:

Shielded twisted pair cable (6 feet Max.: high-speed 

transmission equivalent)

IEEE 1284 - Shielded type bi-directional parallel 

interface cable (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 Operation 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.

Reference:

To use this unit, you must have an adequate 

amount of hard disk space. If there is insufficient 

hard disk space, delete unnecessary files to 

increase the free space of the hard disk. If there is 

insufficient memory, close unnecessary applications 

to increase memory available for printing or 

scanning. If you are still unable to print or scan, 

install more memory into your computer.

When data is frequently stored/deleted, the hard 

disk may become fragmented causing a reduction 

in printing or scanning speed. In this case it is 

recommended to defragment your hard disk. You 

may use the Windows tools or a commercially 

available hard disk defragmenting tool.

The unit may not operate correctly if the parallel 

port mode is set to EPP mode. To set the parallel 

port mode to a mode other than EPP mode, refer to 

your computer manual or ask the manufacturer of 

the computer. ECP mode is recommended to obtain 

the best performance from the unit. Note that some 

computers may use different names for the modes.

If the Plug and Play screen does not appear after you connect the unit to your computer with a USB cable and turn on 
the power of both devices, follow the steps below to verify that the USB port is available.

then click "Performance and Maintenance".
On Windows 98/Me/2000, click the "Start" button, select 

"Settings", and then click "Control Panel".

the "Device Manager" button.
"Universal Serial Bus controllers" will appear in the list 

of devices.

Two items will display, your Controller chipset type and 

Root Hub. If these items appear, you can use the USB 

port. If the "Universal Serial Bus controllers" shows a 

yellow exclamation point or does not appear, you must 

check your computer manual for USB troubleshooting 

or contact your computer manufacturer.
