Initializing means that the printer is starting up and getting all functions ready such as fax, print engine, scanner. If your printer is freezing with just initializing on the screen then there is a problem. If you have added any extra memory to the printer remove and try to restart. Most common failure is the formatter itself.
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.
This is a problem with the formatter board, try doing an nv ram ( turn off the printer and hold down the right arrow and the cancel button, turn the printer back on and continue holding until you see permanent storage init). If this doesn't work call hp tech support 1800 334 5144 and ask for a case number. This printer has a service note which will cover the formatter for 2 years.
The all-in-one product display always reads "Initializing"
This may occur in a low power situation. Follow these steps in order to determine the cause:
Verify that the computer and the all-in-one product have a three-prong power plug.
the product cable from any power strips or surge suppressors, and plug
it directly into a grounded (three-prong) wall outlet.
If the all-in-one has an ADF with an external cable plugging into the back of the product:
Turn off the unit.
Unplug the power cable from the wall outlet.
Unplug the ADF cable from the back of the product.
Plug the ADF cable to the back of the product.
Plug in the power cable, and turn on the power.
If no change, the problem is not the ADF.
If the problem clears, turn off the all-in-one, unplug the power cable, and plug in the ADF.
If the error returns, the ADF is defective. Contact HP Customer Care to get the ADF replaced.
the USB or parallel communication cable from the back of the all-in-one
and try to power up the all-in-one. The computer may be grounding out
through the communications cable. If this corrects the issue, check the
grounding of the computer and outlet.
If the above steps did not resolve your issue, contact HP for additional issue verification or the servicing of your product.
That error means low temperature on the heat roller. The thermistor (something like an electric thermostat) measures the amount of heat needed to work. Error 173 refers a lower temperature than required, while error 172 refers overheat. The complete error list will be of no use to you, since most errors will refer you to an authorized service center.
