Install Polygon mirror motor Lanier 5627. Where is it located?

Hi,
This is Polygon mirror motor problem.
1. Try to turn the main switch off and on.
2. Check the wires.
3. Check the polygon mirror motor PCB connector (bad, loose or broken)
4. Polygon mirror motor no good
5. IPU no good
6. Polygon mirror motor PCB no good

Thanks,

That code is usually a problem inside the laser unit - the polygon mirror motor.

You just bought it...take it back and exchange it for another?

Ricoh CL7300 with SC201.
Due to the age of the machine, it is very likely that the polygon motor is defective. Either the bearing or the electronics for the motor.

The polygon motor is a motor that has a many sided mirror mounted on top of it... a polygon mirror. In this machine, it is two mirrors placed on top of each other. The motors job is to spinn the missors fast and at a steady speed. Several thousand RPMs.
The lasers in the machine is aimed at the mirrors. As the mirrors turn, the laser beams are spread out and go through several lenses and mirrors in order to be able to swipe the length of the drum, and make a latent electrostatic image - that is the key to how a laser copier/printer works.
When the motor is not able to spinn this mirror fast enough due to a worn out bearing (or a defective driver circuit on the PCB that the motor is mounted on) the machine shows an error code.

It must then be replaced.

I've included a few pictures, so it's easier to see.



This shows you basically where the laser housing is located. The polygon mirror motor is inside this houseing. Make sure it is clean inside.



This shows how the lasers hits the two mirrors and some of the path it taked before it svipes the lengt of the drums.



This showes how one mirror is placed on top of the other - and how the laser beams (2) hit each mirror. It is one laser beam for each color in this model.



This shows how you take out the polygon mirror motor, and where it is located inside the laser houseing. Keep it clean.

This is a part that may be better it a technician do the job. If not, get the proper procedure as it requires several steps in service mode for adjustments, calibrations and so on.
It is a fairly quick job for a technician to do. And an easy way to destory the machine for people who does not know what to to.
So make sure you get the proper documentation if you're going to replace it yourself. I'm not saying it is hard - you just have to do it the right way.

This SC-320 code error occurs when polygon mirror motor fails or poor connection between BICU & polygon mirror motor please check first the connector of motor if you feel that the connector is good change the polygon mirroe motor it sits inside the LD unit please call the expert to change the part
thanks

sc320 on the Lanier 5635 is a laser unit error code. Often if you power cycle the machine (turn it off with the orange power switch on the left side of the copier, wait a few seconds, then turn it back on) the code will clear and the copier will resume normal operation. If the error code comes back or doesn't clear, you'll probably need to replace either the entire laser assembly or the polygon mirror motor inside the laser unit. These are best done by a professional -- contact your local Lanier service company if the problem persists.

sc322 is an error with the copier's laser unit. You can pull the laser unit out and clean it up if there is toner on or in it, but more than likely either the polygon mirror motor or the laser unit as a whole assembly should be replaced.

Polygon mirror motor is bad. Sometimes you can put a drop of oil on the shaft, but at best is a temporary fix. You'll end up having to replace it. Good luck

The polygon mirror motor (laser motor) is shot, and needs to be replaced.

Yes this is a Polygon Mirror motor error it is reasonably common in the Lanier digitals. The mirror motor can be ordered separtetly to the laser unit.
