SOURCE: Just got a new HP

Issue with the service station. Turn off and turn on your printer couple of times. Try moving the carriage assy., manually.

Still if it don't work then the service station would have gone bad. Needs to be replaced.

I have a code error 47:03 in my hp t770 and i dont know what to do please help me to solve this problem

47 errors are related to the starwheel motor. This is the motor that lifts the bar that the paper passes under, it has little star shapped wheels on it. If you open the main window and look down you will see it. Make sure it is moving properly and there is no paper jammed under it.

This is problem with the starwheel assembly, make sure that there is no paper stuck under it and restricting movement. The starwheel is the metal bar and little spiky metal wheels that guide the paper.

My hp t770 have this error 59.2:00 after repalcing formatter board plz help me

A 59.2:00 error says that a reused part has been installed.
If you paid for a NEW formatter get your money back and shop somewhere else.
If you paid for a repaired/reconditioned part, it won't work.
You need a NEW formatter.
