Epson Acculaser CX11NF Error 'Service Req E527'


Hi.. To fix the E527 error, close the front panel (cover A) and open the top cover (cover B). With the photoconductor unit removed, the toner carousel will rotate. It only rotates if cover A is closed all the way. You can easily rotate the carousel to a position where you can remove/reinstall the toner cartridge if stuck.

Thanks

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
