Im getting a error E52
Error E52 is a Laser Motor Unit Fault. You can buy a new laser motor unit or try to fix it yourself.
1 - Remove gently the top cover of the
printer ( 4 screws - 2 on top/front + 2 in back/side). [Front screws are
revealed by pulling open the front cover.]
2 - Be careful with the
connectors going to the top LCD panel. You might want to disconnect the
shorter one. [Do disconnect the shorter one.]
3 - Remove the laser unit located on top of the printer covered by a steel plate.
To do that:
1 - Unplug (pull) the white flat connector going to the left side of the laser unit.
2 - Unscrew the 3 screws keeping the laser unit in place.
- The lower/right screw also maintains in place the second connector
going to the unit. Remove it and unplug (pull) the connector.
4 - Squeeze out the laser unit from under the wires (going back and up).
[If there is a wired cable that goes tightly over the unit, unscrew one screw holding the small circuit board in
You now have the laser unit outside of the printer.
- Remove the steel plate of the laser unit. There is a plastic shutter
that will come loose. Don't loose it and take note of its location in
case you need to put it back.
2 - Unscrew the 4 screws maintaining the motor section and remove it. [This is not necessary. Leave the board in place.]
- There is a small piece of black plastic that maintains the top part
of the motor unit (with the mirrors) on the left side of the board.
Twist it and remove it. [Twist it 90 degrees is sufficient; no need to
4 - Pull up the mirror part.
5 - Be careful during
all that not to touch any of the mirrors or prism or whatever seems to
conduct light. If you do, you can always clean with isopropyl alcohol or
glasses solution. [Since you have to touch the mirror to lift it, I
just cleaned it routinely with an alcohol prep pad after I replaced it.]
- Put some sewing machine oil on the shaft.
7 - Put everything back together.
