E511 is a TRO sensor error (cannot detect rotation of PCU belt), don't panic its probably just a dirty sensor. Turn off & raise the scanner unit fully & open the top printer cover. Lift the orange lever and lift the PCU out of the printer using the strap. First of all turn the PCU onto its back but avoid any bright light on the blue roller (it's called the "Drum" and it is light sensitive and very easily scratched so be careful with it and avoid touching the blue surface if possible). Rotate the white plastic gears at the ends of the drum until a little silver square appears in the cut-away section of the cover, this reflects the light onto the sensor so make sure it is cleaned with a soft cloth. Next look inside the printer and you will see a metal strip running across from side to side, mounted on this is the TRO sensor. Give this a clean also with the cloth. One more thing to clean is the sensor at the back, you will see a small black plastic spring loaded lever, push this down and wipe the sensor. Do not try to lift the lever back into position, it will spring back when the PCU is refitted. Refit the PCU, close the covers and give it a try.
If still not working the cause is either a faulty MCU board or possibly a faulty PCU, but to be sure it will need checking by a repair tech as diagnosis by email is difficult.
Good luck, please take a moment to rate this solution, thanks.

I am getting an error message of E 511 what does this mean and how do i fix it? can it be bypasses? how do i reset the unit? Thanks


Hi Collin,
E511 is a TR0 Sensor Fault. This is commonly caused by:

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

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

Hope it may help you.
Have a nice day!

1. Your website has a mind of it's own. Try typing in 'Service Req E511' & the site scrolls on it's own, not allowing me to select anything. 2. I have the above message flashing. After waiting 5 days...


Hi Sharon
I wish some of the users posting questions here had minds of there own.
Anyway,, That issue you're having doesn't happen on my machine, I'm able to type willy-nilly (and a whole lot more).
There's a bunch of answers relating to the E511 message on the Epson pages
just click here http://www.fixya.com/search.aspx?cstm=0&_s=E511
hopefully something there will help.

Epson schematic (e511 error)


Hi-

Try reseating all the toners, as well as the photoconductor unit. If all fails do a reset using the panel. Call manufacturer for 562-276-4382 for step by step instruction.

Hope this helps

No functions are working, error code E511 shows in dialogue box


E511 is in regard to the photoconductor unit. There may be the need to clean the black belt from dust accumulation (other users have reported success by that) whilst I had success by cleaning the surface of the optical sensor on the left, accessible after lifting out the photoconductor. Keep the photoconductor shielded from light while you do this. It usually about stray toner accumulated on surfaces within the printer. Be careful how you remove "dust", a vacumn cleaner can catch fire because the dust is susceptible to electrostatic charge build up.
Hope this helps.

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
