Error message: replace opc belt - Brother HL 2700CN Laser Printer

sc 481 is the OPC belt error. check the opc belt unit. it is also called rum unit. i think the belt is worn out and needs replacing.

Look at the OPC belt edges, there's a shiny spot that passes thru a sensor, a can of air should blow out the sensor, carefully! When the sensor can't see the timing spot you get that error. You may have to replace the OPC since companies are imbedding a chip that tells the machine when they're used up.

make sure all components are properly seated. also try turning the printer off and waiting a few minutes and turn back on.

The SVC E9 error on the 8008 indicates a 'Belt Marker' error.
Basicaly the printer is not detecting the OPC belt rotating.
Check the OPC is not damaged, in particular check the left side of the OPC there should be a black squair that trips the light sensor which detects the OPC belt rotating. Check there is no damage here.

Locate the belt mamarker sensor, and clean it, this is on th left side of the pritner towards the top near the drum cleaner I think. It reflects of the left side of the OPC belt.

Check the OPC belt is turning, there could be a motor / drive problem.

Perhaps your OPC belt is at the end of its life and needs replacing

The SVC E9 error indicates a 'BELT MARKER' error.
This means the printer is not detecting the OPC Belt as rotating.

This error can be caused by a damaged OPC belt, you can check this by removing the OPC belt from the printer and look at the OPC belt it should have a smooth green coating if there is damage to this belt it may cause this error.

The error can also be caused by a damaged 'Transfer Belt' when the OPC belt has been removed from the printer look inside the printer where the OPC belt used to be located you should see a black belt towards the back of the printer, if this belt is damaged it can also cause the error.

Ensure the OPC Belt locates in the printer correctly.

If the OPC belt and Transfer belt look to be free from damage and a are located correctly in the printer you may have a faulty belt marker sensor or faulty OPC belt.
You can try substituting the OPC belt for an alternative one if you have this available to see if you can narrow the problem down to the sensor.

The error indicated on the 8008, ‘SVC E9’ indicates the printer is not detecting the OPC Belt as rotating in the printer. The printer ‘looks’ for two black squires on the left side of the OPC Belt (as viewed from the front of the printer) if the printer does not ‘see’ black squires the printer indicates the SVC E9 error.

If the printer is displaying the SVC E9 error the most likely cause is something to do with the OPC Belt, normally removing the OPC belt from the printer then re-seating the belt would resolve the problem in most cases, as the OPC belt may not be locating correctly in the printer.
Unfortunately you have already removed the OPC Belt from the printer without resolving the problem, it may however be worth removing the OPC belt again and to look at the green reflective surface to see if there any damage or if the green surface is fairly central and is no skewed or bent in any way.

Depending on which position the OPC belt stops in you may see the black squares down the left side of the belt, if you can see these and they don’t look damaged or scratched the printer should detect the OPC belt ok, so the problem may lie with the sensor on the printer its self.

the opc belt is the optical photo conductor belt in your printer. It is the bright green shiney belt you see when you remove a cartridge. You can access it through the top of your unit. You will see a cover where the paper comes out. Inside there are two green clips that push outward. These release the opc belt.
You can purchase a replacement opc belt from most good stationary and consumable suppliers, however, be ready for a shock. the price of the opc belt is almost as much as the unit is worth.
