-922 Fuser Error messages indicate that the fuser unit failed to reach the standby temperature.
If this is the first time you have seen the error, turn the printer off and on.
-Leave the printer off for at least 10 seconds before turning it back on. This gives the printer's engine board a chance to reset.
If this is an intermittent error, you may want to check how the printer is plugged in, even if it has worked on this surge device for months. Make sure the printer is plugged straight to the wall and not through a surge device or power strip. Power strips and uninterrupted power supplies can cause a low amperage problem in your printer which can trigger a false fuser error.
If this does not help or if this error appears every time the printer is powered on, you will probably need service on the machine.

- 923 Fuser Error indicates that the fuser unit is getting too hot while printing or when the printer is idle. Make sure that nothing is stuck inside the fuser unit that can cause the fuser unit to overheat. To check for any stuck sheets of paper in the fuser unit:
Locate the rear door and open it. The rear door opens and drops down towards you.
Look into the back of the printer. See if there is any paper or any other item stuck there that could be causing the fuser unit to overheat.
If you cannot find anything jammed up or broken in the back of the printer, open the upper front cover of the printer and remove the toner cartridge. Look into the printer from the front. See if you can see anything jammed into the back area of the printer.
If nothing appears to be jammed in the printer, the fuser unit or the main power supply of the printer will probably need to be replaced to fix this problem.

check in the duplex unit

You need to install duplex in your windows driver printer dialogue
