canon irc 2880 light at bottom of page

[lightningjeremy]

ive got a 2880 that has weak solids at the bottom. all the colors are equally weak, so i am thinking it is transfer related. i tried cleaning the transfer roller with no change in cq. the machine has just over 200k. thanx

check that the ITB Assembly is locked in and engaging correctly
check contact for bias tab on the transfer roller assembly

Check if ITB ground wire is firmly attached at HVT2 and the grounding screw at the ITB frame.

I agree with secondary transfer as the issue. Print a test page 10. If all colors are light at the same end, it is unlikely that all 4 primary transfer rollers would exhibit the same problem, so most likely culprit would be transfer roller mounted on the right door...
