Failure in initialization of Scanner. Scanner is offline or , scanner is turned off.

Scanner initialization failed, and the copy processor
board (CPB) is not communicating
with the scanner-controller board (SCB).
1. Turn the product off, and then on.
2. Check the scanner controller board
LEDs.
3. Check the connections to the scanner
controller board.
4. Replace the scanner controller board.

Please try this!!
You may need a soft or hard reset. Here's some reading and instructions.
Please use this first!
resetting your scanner
1. Turn off your scanner, and then turn it on again.

2. Insert a pointed object into the reset hole on the back
of the scanner. Then, gently press and release the reset
button. Pressing reset does not clear the scanner's
working memory or the V-Scanner folders.

If this doesn't work here's step two! CAUTION. THIS WILL ERASE EVERYTHING, but it MAY Fix the Problem!!

Initializing your scanner clears all information stored in your
scanner's working memory. Initialize your scanner only when
you are sure it is not working properly. V-Scanner memory is
not affected when you initialize the scanner.

1. Turn off the scanner, and turn it on again. First, the DSP
boot version, and then Welcome To Digital Trunking appears.

2. Press 0. The following messages appear on the display:

System Tests

Select Test
Exits if no
Key Press

3. Press 1. The following messages appear on the display:

Factory Init
Erase Memory
ENTER if Yes
CL to EXIT

4. Press ENT. The following messages appear on the display:

Initializing
Clr Main Mem
V-Scan is OK
Please Wait

5. Do not turn off your scanner until the initialization is
complete. When the initialization is complete, M000 and
Bank 0 Ch 00 appear on the display.

Hope this works.. Happy Scanning

Please try this:
If the scanner's display locks up or does not work properly after you connect a power source, you might need to reset or initialize it. If you have problems with the scanner, first try to reset it to retain the memory. Warning: Initializing the scanner will clear all channel memories and reverts it the state it was in right out of the box.To Initialize the scanner, turn off the scanner then turn it back on. Press 0 when the welcome screen appears. 'Please select factory tests. Exit if no key is pressed' will briefly appear. Then quickly press 1. 'Initialization clear all memory Enter to confirm Clear to exit' will briefly appear. Quickly press ENT to initialize. 'Initializing, Please stand by' then appears. Do not turn off the scanner while it is initializing. The display should then show M000 on the top line and Bank 0 CH 00 when finished.

Hope that helps.
Happy Scanning!!

first most computers are plug and play, if yours is not then you need to load the software that came with the scanner, only then will the computer see the scanner

Is there any error message displayed on the control panel of the printer just like one of the following:
Scanner failure, power off and on
Scanner System Failure
Scanner failed, cannot make copies or fax
Scanner failure. Unable to scan, copy, or send a fax
Scanner failure, cycle power

You may want to try following these steps:
1. Check if the scanner light does turn on when you initiated the scanning process, if not you need to reset the product.
2. Try using your other electrical outlet because your AVR or Surge Extension may not be providing enough voltage for the printer.
3. Try using dirty cycle, meaning you need to directly cut the power of your printer by pulling of the power cord from the rear side of your printer and wait for about 30 seconds before inserting again and turn it on.

If all these steps do not improve your printer functionality, you may want to call the HP online help and ask for replacement.

replace the Scanner Assembly

This scanner requires a "Parallel or Centronics" cable and if you have a newer computer, you may only have USB connections. A "USB to CENTRONICS" cable may do the trick, but I'm not sure. Check on the web for one.

have you tried to reset the printer?

(Take the power cord off hold # 3and then turn the printer on.)
That is an initial position problem

Parts are no longer available for this model from HP...

This is probably a power issue. If you have many devices plugged in to one socket, the printer can't get enough power to start up or start the scanner. If you have a power extended cable, remover it and plug in te printer direct in the wallsocket.

Don't worry about the clean roller message. It is just a reminder much like your scheduled maintenance light that appears in your car.

Start Failure can occur for a number of reasons. When you get a start failure message close your scanning software and reopen it. Sometimes your connection may degrade if left idle. If that doesn't work shut down the scanner and pc. Turn on the scanner and wait until it is fully initialized before turning on the PC. These steps have resolved that problem for me. Lacking a manual, I just try things. Good Luck
