    sharp MX-2700N Black Printing with section loss

    I have a sharp MX-2700N and just change drum, black developer and primary and secondary transfer belt. Everything works fine with the color printing except black. CCF12272013.pdf
    One section of the black is not printing, and black seems lighter compare to other colors. Is it something to do with calibration, or is there any other section that might need to look into.
    Thanks in advance.

      Have you cleaned the laser slit glasses? What calibration have you done so far? =^..^=
      If you'd like a serious answer to your request:
      1) demonstrate that you've read the manual
      2) demonstrate that you made some attempt to fix it.
      3) if you're going to ask about jams include the jam code.
      4) if you're going to ask about an error code include the error code.
      5) You are the person onsite. Only you can make observations.

          I'm with Blackcat, cleaning and calibration. LSU and if there is a DCH lens on drum, that may cause issue. It is the clear plastic that would sit on cleaning blade, there is 1 on the 2600 model.

              Try removing the shutter. It is very easy to remove and reinstall.

                  Thanks everyone for the help and especially blackcat for pointing out the laser slit glasses. The problem is the laser slit glasses. I guess it has too much power build up when the developer rubber blade went bad. A good two pass cleaning, everything everything prints perfect.

                      Congratulations. Any time you remove developing units or drums toner sprinkles down, and you have to clean the slit glasses again.

                      Sharp must be the only manufacturer that hasn't figured out how to make an automatic slit glass wiper. =^..^=

                          The reality is probably copyright and patent laws preventing an easy method of setting up something that won't infringe on another manufacturer's rights. In all reality, the only ones who see it are techs (ideally) and we know it needs to be clean anyways, why create some automated system that can break and cause us more trouble when our hands work just fine?
                          Cthulhu for president! Why settle for the lesser evil?
