Darker images after first developer change MX2700

[sharphead]

Has anyone else noticed this, I was told to change the developer and drums in a copier in the office. I took prints before hand of the tiger in sharpdesk, after maintence and colour calibration the image is def darker not a lot but noticable I have noticed this before and it seems to always occurr after the first change of developer

cheers

Could be wrong - but I do not remember the counters impacting CQ (but yes you should clear them).

Did you do your standard sims (50-22, 44-06 etc) for maintenance after changing the drums and developer? Others may differ, but I am anal enough to follow the manual without skipping steps.
