    MX2640 E7-23

    Hi, I’ve got this code recurring randomly on a 2640, cleaned the yellow laser unit, new drum and charge kit, calibrated etc and all ok. Then back in again today, I’ve never had a laser fail on one of these? Have you or is it something else?

    Do you just replace the yellow or the whole rack? Is it straightforward to do?

    would you know if the lasers are the same in a 2614 and a 2640 as I have a scrap 2514 here and could take the unit with me

    I don't think so.

    This is how the Parts Guide breaks them down:

    MX-3140N, MX-2640N DUNT-8947DS11

    MX-3116N, MX-2616N, MX-3115N, MX-2615N, MX-2615N, MX-3114N, MX-2614N DUNT-8502DS15

    MX-3640N DUNT-8948DS14
