    light copy ir 2520

    hi..
    I have a problem in IR 2520, it print out very light copy. the total counter of machine is about 6000 copies. the first toner bottle not finished.
    I check the transfer roller and it seems good.
    I also checked the charge roller of the drum also it seems good.
    I noticed that the latent image on the drum surface is very light, no black image was there.
    i print out the counter for test also it was light copy.
    please can anyone help me th solve this problem.

    did you check the dev unit contacts to be fully in contact with the machine body ?

        We have had this twice now - both times on machines that had done less than 10k with their original toner. Only way we could resolve it was to vac out the dev unit and re-start with fresh toner. Neither machine caused same problem again (to date!).

          If the machine is not printing regularly, toner on the dev. cylinder and in the the dev. assembly gets "saturated" resulting a light image. This was common in GP605 machines.
