Hope this helps, if so do rate the solution Good Luck

Background of issue- When 4345/M4345 boots up, amber light comes on under start button and the message "Initializing Scanner" is displayed. The unit will print but will not preform any scan functions.

Steps taken to try to resolve issue:
1. Updated firmware
2. Restored factory defaults
3. Took off cover in back of printer covering scanner controller board and reseated all cables
4. Took apart scan unit and cleaned (2)mirrors in scan head
5. Took off back cover of unit, reseated cables coming from scanner controller board
6. Ran Scanner Test, in menu (which everything functions properly)

Usually I would say scanner or controller board has failed but I had 3 M4345 come down with this issue in one week. The only resolve i've found for this issue is repetitively turning on and off the unit until it comes up without "scanner initializing" message. Once it comes up it functions 100% until the unit is turned off and issue will come back.

I'm at a loss here with so many units having same issue, open to any advice. I once took the formatter out of bad unit and put it in good one and it caused the issue in the good one but i'm double verifying this tonight. Thanks for any help.

The ERROR message normally indicates that you've entered a frequency that's out of the scanner's tuning range. Check your manual to confirm that your frequencies are within the unit's reception capabilities. If the freq is in range and the problem continues, you may need to RESET or INITIALIZE the scanner to restore it to its original factory settings.

To RESET the PRO-135:
1. Power the scanner OFF.
2. While holding in the 2, 9 and PSE keys, power the scanner on. The process takes about 3 seconds to complete.

To INITIALIZE the scanner:
1. Power the scanner OFF
2. While holding in the 3, ENT, and PGM keys, power the scanner ON.
NOTE: The INITIALIZE process will delete/erase all of the information that you've programmed into the scanner.

Most likely cause of the "Scanner could not be initialized" error on the HP Scanjet 3970 is due to using an incorrect power adapter and cord -- the only power module and cord that work for the HP Scanjet 3970 are these part numbers: 8120-6260 for the power cord and L1970-80003 for the power module / AC adapter I hope this info helps you.

First, power the printer off, wait for about 30secs and power on. If problem persist replace the scanner.

Pull the battery out, press the trigger for 5 secs and you are done
