E511 is a TR0 Sensor Fault. Can be caused by:

Photoconductor Unit
SENSOR TR-0
HARNESS-ASSY XERO
MOTOR ASSY P/R
HARNESS ASSY MAIN
PWBA MCU
LV/HVPS

Not really something easy to fix at home.

    NEW INFO:



    Look at the bar code label on your PCU unit. If the lot number on it
    (see pic below) is in the range 711 to 78A then the PCU is from a
    faulty batch.



    Returning to Epson for a new one should sort the issue.

After changing the black cartridge of epson aculaser c1100, a message flashed: Service Req E511


Hello,

Welcome to FixYa, the world's largest product support community.

The message E 511: Service Required is commonly due to the Photo Conductor Unit's tabs getting stuck. So the first thing we need to do is to remove the PHoto Conductor Unit. Here are the step to remove the Photo Conductor Unit off of your EPSON Aculaser C1100.

1. Turn the printer on, and open cover B.

2. Raise the yellow lever inside cover B.

3. Remove the photoconductor unit.

4. Check the white tabs on the underside of the photoconductor unit. These are spring-loaded plastic tabs that should depress when you press and release it. If the white tabs no longer spring back you need to replace the photoconductor unit.

After removing or ultimately replacing the photoconductor unit, please follow the step by step giude on how to remove the photoconductor unit in reverse order.

This is not Diy, I've advice you to send the unit to your local Epson Service center.

Hope it may help you.

Printer displaying "Service Req E511" and wont print


Error E511 relates to the PCU (not detecting the transfer belt rotating).
This appears to be common. Sometimes the belt can slide on the rollers to the left, thus the square metallic reflective spot on the belt does not pass over the TR0 sensor, no amount of cleaning will cure this, you either need to strip the top cover off hte PCU (6screws) and pull the belt back over to the left or replace the PCU all together. BTW PCU stands for Photoconductor Unit if you didn't know.

Service reqd E511


I was able to get hold of a schematic diagram to locate the part number for sensor :
part code 2090463 SENSOR TR-0
When I inspected the original part the pcb was cracked therefore the sensor was unable to dectect the 'mirror' which is a silver square located on belt on photo con unit.
If you require a copy of the schematic diagram (pdf) let me know an address to send it to.

Regards

Rob

Epson Aculaser C1100 - E511


The E511 error comes when you power up the printer. The noise of the "warm up" is the black rubber transfer belt on the Photo Conductor Unit spinning through one rev to check for a little silver square on the edge of the belt. You can turn the belt manually to see this square.

If this square is not found, Epson will tell you to throw away an otherwise fine PCU.
Solution:
a) Remove PCU and check the transfer belt for the square. Clean WITHOUT alcohol.
b) check the sensor that reads this square - a small black oblong "camera" in the heart of the printer on the LHS. Clean.
c) If the square is damaged, replace with a piece of tin foil. Superglue on carefully, making sure all the edges are glued but not your fingers!

You don't need to put the new square in exactly the same place, just above or below on the belt is fine.
