Brother MFC 9420FN Needs a polygon motor. Can just the motor be replaced or must it take a laser unit. Which ever, how much is the cost if available. We are a Samsung dealer and one of are customers asked us to look at this machine. We do know what the polygon motor sounds like when its bad. Thank you for your help, Wayne

This is due to Polygon Motor Error in the Laser Unit.
Pls try one of these:
1. Input the correction value of the laser unit correctly.
2. Check the harness connection of the laser unit. Try re-connect them.
3. Replace main PCB Assembly.
4. Replace the laser unit.

Print unable 71


Print Unable 71 means Polygon Mirror Failure on the Brother HL-4040, MFC-9840 and MFC-9440.
Pretty safe to say it means the same thing on the MFC-8880.

The Polygon Mirror is part of the Laser Unit, and its rpm isn't within specs.
The Laser Unit must be replaced.

What is machine error 71 How to fix it?


Error 71 on a MFC-9600 means there is a problem with the motor inside the printer.
You can try unplugging and waiting a few minutes, then plugging back in again.
If it is still coming up with the error, if its still under warranty Brother will replace/repair it for you, otherwise you will have to pay Brother for the repair cost.

It is a Sharp al 1000 with error message L6 which means Polygon mirror motor not up to speed? How is this fixed and what cost?


Since the polygon motor is part of the laser unit, it would cost about $200 plus labor to replace it

Mfc9880 machine error 71


error 71 is a problem with the polygon motor which is in the laser unit. This error usually means that you would need the laser unit replaced.
I'd suggest calling out an engineer.

Polygon mirror motor not up to speed. Check the motor, you power supply, and the board the motor it connected to.

Unit 11 laser polygon motor failure


Most likely, all the problems you are experiencing are being caused by a bad laser motor assembly. We can send you a motor assembly for the laser unit and you can change it out yourself, however, we will have to charge for the entire unit since it makes one laser unit worthless. You would save on shipping that way. Aligning the lasers is a little tricky, but doable. The manual can be downloaded at: www.lpscomputer.com/ec/Phaser_7700_Service_Manual.pdf
The parts can be ordered at: http://www.lpscomputer.com/p-3060-1-116-1110-00-laser-unit.aspx
