Laser and led array that discharges the drum

Re: Mp5002 streaks

I would say that the led array that's meant to discharge the drum has maybe gone faulty. Cant see the laser causing that but have seem the discharge lamps cause print quality issues

Quenching lamps I think they are called?
I have seen on mp2550 a couple of years ago they went faulty and it kept causing every page to be gritty all over, one to remember as have never had any other problems involving quenching lamps before.

Re: Mp5002 streaks

Seems also that maybe the machine is not rotating the cleaning web. Any ideas on this?

Re: Mp5002 streaks

If the fuser Web is still attached how about removing it to see if you get a different result? Also there's a fuser cleaning roller that might need cleaned inside the front of the fuser

I already mentioned removing the web unit to test

Re: Mp5002 streaks

Also you can remove the web completely and the machine will still work with no problems

Re: Mp5002 streaks

Measure the spacing between the streaks. That is the diameter of the source.

Re: Mp5002 streaks

Well the only thing you can do is jam the machine. You can open the right hand door when a page is going up the vertical feed try and stop it at the drum to see if the marks appear there and then try stop it at the fuser. I know you tried different units but maybe this will help indicate where the fault is coming from?

Re: Mp5002 streaks

Looking at the parts catalog I would say it is mounted to the frame stay with double sided tape. You can remove the entire stay assembly with 2 screws at the front, there is a tab that goes into a slot in the back frame when putting back in.

Re: Mp5002 streaks

Hi,

I had this problem in MP3353, new drum, charge roller, charge cleaner, developer, fuser...etc PM parts. Since the machine is not frequently serviced, the seal covering the toner recycling unit is bent and out of position causing it to dump unwanted toner.

Please check if you have the same deformed seal.
