To prevent future problems with your HP Designjet T770 and T1200 printer´s Media Advance system (starwheel motor issue), we recommend to upgrade your printer to latest firmware version 22.214.171.124 available. Check out the Customer advisory note: www.hp.com/go/tseriesfw for more details.
The firmware file is about 50MB and it will take around 15min to update your printer. Files are ready for download here:

There is a service note on this since 7/29/2011:

I have experienced this error, but there is always a broken gear on the star wheel motor. Does this upgrade stop the gear from breaking, or is it just to stop 'phantom' star wheel errors?

No, it actually prevents the cogs from breaking. Now it is less paper axis movement when going out of sleep mode, as one example.

It appears to me that if you get this code you now have a problem in that starwheel drive area and simply updating firmware will not fix it. The firmware is to stop the starwheel gears from breaking in the future, but if they are broken now, they will need to be replaced.

i forgetted to let you know that starweehl have been already changed.
Gears are not broken now, but always the same message on my panel "47:03"

Hi, I have the same problem. My printer show 47:01 error, after replaced new sstartweel motor, it's startup ok but when I print, the first page is ok, but when printing the sendcond page, it's show 81:01 error. I turn off printer about 15' and then reprint, the problem still happen as above. How can i solve this issuse?

Could you please advise on how you fixed the problem. Am getting the same error today. 47:01 Restart the printer. If the problem persists, contact HP Support.

i downloaded the new firmware, how can i update it, my computer is a stand alone system that is not connected to the internet. i used HP utility/support but it wants to go to the web

How did you access the internet to download the firmware?
Use a USB flash drive to perform a firmware upgrade
1. Turn off the printer.
2. Ensure that your USB flash drive contains a valid FMW firmware file and no other files.
3. Connect the USB flash drive to the USB host port on the formatter.
4. Turn on the printer and follow the instructions on the front panel.

Download the FWM firmware file from the HP Web site.
Store the file in a standard USB flash drive with no other files. Connect this alternative flash drive
to the formatter's USB host port to perform the firmware upgrade, following the instructions on the

If your firmware is below this level then it needs to be updated. IG_01_07_02.1

After receiving the 47.01 error due to out-of-date firmware, we installed the updated firmware via USB. On reboot, we received the same 47.01 error.
On secondary reboot to diagnostics mode, we reset EEPROM and rebooted. [79.xx error.]
On third reboot to diagnostics mode, we ran the starwheel diagnostics tests: the only error that came back was on the starwheel lifter test: out of range.
Subsequent reboots returned the 47.01 error.
Are there any calibrations we should also perform, given that we updated firmware *after* receiving the 47.01 error and causing a non-functional printer?
Many thanks for all help,

It sounds like your starwheel motor drive assembly is broken and will need replacement, the firmware upgrade is only a fix to stop the starwheel motor assembly from breaking in the future, but since you have that code now, the part will need replacement.

Hi, I've done the FW upgrade 7.01.2?, the latest anyway. Is there something about this update that may cause me to continually get error 45.1:03 upon startup? upon doing the rewinder test I get 45.1:10 - replace.
Keep in mind I did cross the 2 parallel cables to the formatter board, and that I think I may have burned the rewinder motor out, possibly, not sure. (after I crossed them, I would get error 22.0:10 but due to the crossing of the 2 cables.)
If there is something inherent in the latest FW upgrade that needs to be addressed in order to get around error 45.1:03, please let me know.
Thanks for any and all help.

I just wanted to clarify that you actually crossed the connectors on the main board of the electronics unit, the formatter board is where you plug the network cable into on the rear of the printer. I just didn't want you to possibly order the wrong part.
