how to print 300 dpi in Canon LBP2900B Laser printer

Hi,

The error would be stating LSU. It stands for Laser Scanning Unit.
The LSU error signifies that there is an issue with the laser scanner, the part that helps making prints.
There could be an issue with the laser or perhaps the polygon mirror, maybe the sensor or a combination of these that needs to be fixed.

In the User's manual it is stated:
To turn off power and wait for 20 seconds. Then turn on the power again.

If the problem is still there then you will need to call for service.
The service tech will recommend a new laser unit or control board.

Best of luck!

If the printer cannot print or move any paper, follow these steps to display the Event Log. Otherwise, print the Event Log.

1. Press Menu until INFORMATION MENU appears.
2. Press Item until SHOW EVENT LOG appears. Press Select to show the Event Log.
3. Press - Value + to scroll through the Event Log.
4. Write down the error messages.

If you see a 52.X error then this indicates the following:

0 Laser/Scanner Error
1 Laser/Scanner Startup Error
2 laser/Scanner Rotation Error

ACTION:

1. Press GO. The page containing the error will automatically be reprinted.
2. Turn the printer off, and then turn the printer on.
3. Reseat the cables fort the Laser / Scanner Assembly.
4. Replace the Laser/Scanner Assembly

That is a laser alignment issue...
You might get lucky:

1. unplug printer power cord from wall or powerstrip.
2. Turn ON printer (without the powercord plugged in).
3. Plug in powercord and turn ON printer again.

If error code 71 remains .... repeat above steps.... but I would advise replacing ($180 ~ $240) instead of repairing ($150)...

Hope this helps!
