I have A problem with an HP Laserjet flow M830z. It comes up with error 30.03.23 and the copy output has streaks. I did some research and in most cases they suggest a firmware upgrade (which i have done and the error returned after.) or replace scanner. The printer has not been moved in the last two year and i need to get to work ASAP. Is there anything else i can do before i go through the lengthy process of replacing the scanner unit. Please Help

I have never tried with that model but in some cases you can clean the optics in the scanner.
Have you looked online to see if you can find the service manual or they might call it a repair manual. (On some newer models the manual is split into two manuals, troubleshooting, and repair)

30.03.23 Error Alignment Calibration Failure appears on the control panel it indicates that there is an issue calibrating the scanner.
Symptioms: Vertical or hprizontal line will appears on copy out or scan out from ADF.. see the snaps.
Hp know about this error.. I faced this error 4months back, I replaced both Flatbed scanner unit & SCB board at a time, after that I rolled back to previous firmware, then error got resolved..
Sorry to say that the Firmware link was expired which I got from HP team. Try to rollback previous firmware if any one helped from our forum, then check it, if not resolved then you need to replace both above said parts.
Keep posting for further assistance..

I cant seem to find another version of the firmware. Anyone with a link. Also does anyone know the cause of the error. My research is saying the scanner calibration lining could have moved, but i cant find the the scanner calibration lining in the service manual to check on it. Please help.

Hi Again this is Vinay.,
There is a 24pin black flat cable between SCB board & inter connect PCA, if this cable faulty (continuity failed) you may get the same error...
Detach this cable & check for the continuity.. This cable is very delicate, if found faulty replace it.
some of useful information as snaps
Scanner control board(SCB): P/No CF066-67911.
24 pin Flat cable..
Thanks for kudo..

Thank you for the responses. Very much appreciated. I checked comtinuity on the cable. It was fine. I still can't find old version of firmware. Sent an email to HP hope to get from them.
I will check volntages this afternoon.
Thank you again
