I've got a DP4510 that gives a 1cm background on the lead edge of the copies.The rest of the copies are perfect.What could this be and what should I look for.Any ideas welkom

Is it doing it from the ADF? If so adjust your ADF lead edge timing. If its only on the glass adjust your lead edge void. Both can be found in F5. Good Luck.

this is a common fault on these models

take the drum unit out, remove the drum and check the catch blade (below the drum blade)

bend it back out or replace

check the sensors that sit towards the back of the drum unit just below the catch blade

check the transfer unit to see if u have a layer of toner on it

remove the dev unit & place it on the desk, rotate it anticlockwise to seeif a layer of toner lands on the desk, u may need to replace the dev

Hope that helps
