Re: mpc2551

where do the image get fainted? on drum? transferbelt? - you can test if you interrupt the print and check the surfaces

Re: mpc2551

just the drum or dev unit as well? in case the dev unit hasn't been replace you can try toner add via sp and see if the density improves. what about C/M/Y - do the colour looks weak as well?

You might check all HV/bias/ground contacs

Re: mpc2551

Going right back to basics, did you clean the LD glass with the little wand thingy? Is the drum/dev up to PM?

Re: mpc2551

You said you replaced parts, could you tell us which parts you replaced? Because that sure looks like you just have a worn out PCU, and the numbers on the image you shared make it look even more so.
