[CQ] Nashuatec MP 2000

[brunot]

Hi everyone,
I need your help,
After a general servicing,when i try to print the total counter(User tools) it's ok ,so i think that the Photoconductor Unit (PCU) is ok but when i places a document on the exposure glass or in the ADF unit to make a copy,i got plenty of black lines on the copy. Then after some copies,the machine indicate sc code 144. I have replaced the SBU,there was no sc code but the black lines were there. I have replaced the whole scanner unit,the BICU even the LD unit but the black lines remain on the copies,either using exposure glass or ADF.
Please adviced.
Thanks and regards.

I presume the optics and the white plate are clean. Check the mirrors for deviations and run SBU-Auto Adjustment in SP4-428.

when you replaced the lens block did you also replace the ribbon cable from the ccd array. i have had this issue on a smaller MP171 machine before and it was the ccd ribbon cable.

Thanks for your reply but i removed the whole scanner unit(mirrors,CCD,SBU,cables) from another machine and put it on this one . I also replaced the BICU.

You can try to adjust the "ADS-Level"
SP 4-903 to 180-190.

good luck!
