When I try to run a job with a big, bold, black headline of type the first copy out looks great! but as I continue to run the job, the 25th copy looks lighter, more faded and by the time I get to the 50th copy, it looks like ****.
Now, here is the curious part.
If I let the copier sit for awhile and run the job again, the same thing will happen, the first couple copies will look great and then it fades out.
So because the first couple copies look great, I know it is capable of it, but I don't know if the toner feed just can't keep up or it is the developer unit or xerographic belt or what.
Please help! To get Xerox to come and fix this costs a million dollars and then they don't even fix it! I paid over $3,000 for them to replace lots of stuff and it they end up replacing a 39 cent belt! Did they give me my $3,000 back when they figured out it was the belt? Hell no!

You have no light output. The system places a charge, the image will remove charge (without image processing, the system leaves full charge ) (removes charge where no image is if negative processing)
EX: a copier has platen closed makes a copy because the cover has a white surface the light is reflected and removes charge from Drum. If you make a copy with platen open out put will appear black. Charge was not erased, toner is attracted to charged area.
Most systems use a small wire to place charge, depending on what development (pos or neg) with broken wire will also result in either a black or blank output. I would look for a broken charge wire.
Try something, Send a job with 5 pages to it. Shut the machine off as a page it halfway out of the exit area.. Open the machine and look at the jammed copies. Are they clear in the imaging unit areas but not upon exiting the machine? If the image is clear around the drums and imaging unit, then the problem would be in the fuser. If the image is grainy and fuzzy in the image area, You could have a bad second BTR roller, the soft black roller on the left side door. One of the developer housings could be bad. You have to remove the imaging units and look in the opening with a flashlight to see if the developer housing brush is thick on the developer roll. Could have a bad transfer belt or one of the color housings could be bad. Less likely is a bad laser. But have you taken the wand that is on the front cover and cleaned the laser exposure slots?
The metering blades in those cartridges go bad and do not allow the ink to get to the page. Look at the front of the toner cartridge, is should be a solid consistent black all the way across, if its streaky, not consistent all the way across replace the toner. The other problem could be a dirty laser. If replacing the toner doesnt work let me know, I will tell you how to remove and clean the laser.
i had similar problem a week ago running black only job on extra heavy card stock. there is black toner built up. when you run black only copy with little toner use, it builds up toner in black developer and motor could not run. always mix black and color jobs and run alternate, so there is no excesses in any color. or cheaper way how i did without paying color clicks. i got rid of excess black in following manner. took 11x17 white sheet, copied as negative (solid black) and ran 30-50 black copies, which drained all excess black and then continued with job. hope it works for you or get professional help or you will lose motherboard and motor if you just follow instruction as it tells you on error screen... switch off and switch on. do not keep on repeating.
NOTE: The problem occurs because of the trickle development system in the machine, making extended lengths of black and white copies / prints does not allow the black developer housing to purge itself of excess waste Toner (Dry Ink) and Developer. There are two solutions for the problem:
Make 1,000 copies / prints of a black and white job, then make 150 copies / prints of full color. Continue making 1,000 copies / prints of the black and white job, then 150 full color, and so on, until the entire black and white job is complete.
Make extended jobs in groups of 100 by making 100 copies / prints of the black and white job, then allowing the machine to cycle down (return to 'Ready') and making the next 100 copies / prints. Continue in this pattern until the entire black and white job is complete.
NOTE: The above solutions are based on jobs using 8.5 x 11 inch paper, single sided, with no more than 28% coverage.
Black toner problem.Probably You have low toner sensor defect.
But try first to vacuum and clean black toner dispenser.You must vacuum whole path wich is used to transport black toner to developer unit.Then if printing B/W print only, you must print 10 full color sheets every 100 copies.
