HP Network Scanjet 5 Scanner series - Manual (Page 100)

Scanner Troubleshooting
If you have problems with the scanner, proceed as described in the
following paragraphs.
Scanner is not Working
Make sure of the following:
•
The power cord is connected securely to the scanner and is plugged into
an electrical outlet.
•
The scanner is turned on.
•
The scanner is connected to the network.
•
The scanner is unlocked. If you try to scan a document when the scanner
is locked, it will emit a harsh, grinding sound.
If these conditions are met, turn the scanner off, wait 30 seconds, and
turn the scanner back on to reset it.
Control Panel is not Working
Make sure of the following:
•
The power cord is plugged into an electrical outlet.
•
The control panel is correctly connected to the network box.
•
Check the control panel contrast. You can change the contrast using the
arrow keys.
If the problem persists, call your network administrator.
Scanned Image Quality is Poor
If scanned pages are blank, white, or have repeated patterns, first make
sure that a page is not already on the scanner glass.
Scanner Overheats
The scanner automatically shuts off if environmental conditions cause it
to overheat. If this happens, switch the on/off switch to off, wait for the
scanner to cool down, and switch on the scanner to operate.
