Thank AMZITMAN for his writing, which is Very helpful. I had relaced toner cartridge three times, but "print faded (faint)" issue was still the same as before. Then I found AMZITMAN's suggestion, which is very clear step by step. I let motor run 30 seconds at first, the issue was still the same as before; but after I run second time (15 seconds), It works!! Appreciate AMZITMAN
I have a Xerox 6015NI, and this procedure did not work because the options appearing on the 6015NI menu did not match these instructions for this fix for the Xerox 6500. So I quit trying and began looking for a replacement printer. I vowed never again a Xerox printer, but after my following experience, I think I will only get another Xerox.
A few days later I needed to print text document, and as a work around, I selected very dark blue font to get the printed text I needed. This worked for what I needed, and what the hey? That cyan toner on the shelf will be worthless anyway when the printer goes away.
Then the miracle began....A few seconds after the dark blue print job finished, my printer, all on its own began to make its usual "I am getting ready" noises, and then began to make a runh-runh-runh-runh sound that lasted for about a minute. Huh, what? Is it trying to fix itself???? So after it quieted down, I printed a Windows printer test page, and to my everlasting surprise, it was beautiful dark black. How could it be? I then configured the printer menu to constrain the printer to print all black and ran the test page again. Perfect again except the red-yellow-green blue Microsoft logo was in black-white.
I cannot explain this, but I did note the printer is supposed to self-actuate some maintenance cycles when certain things occur. I did not get any improvement when I previously attempted manually running the maintenance cycles. Perhaps printing with only cyan toner triggered a maintenance routine that resulted in the self-fix.
I also note that my faded text problem began when the toner ran out before the printer stopped printing, which it never did before. Every other time it needed new toner, It just stopped printing and displayed a message to change the toner cartridge. This time, when I put in a new black cartridge, I continued to have faded black. I think it might be like filling a car's gas tank, in that if it runs completely out, it will have trouble starting up again, and that is why the toner cartridges are programmed to not allow any printing when they become critically low.
Who knows. Maybe the printer is possessed. That would not surprise me more than what happened. Sorry to be non-scientific about my experience. I swear this is what really happened.
This must be great for that rointer but the 6250 has a different mechancical set up with the imager.
How can I do a similar thing with it please?
Thanks again, nivek! This worked for me as well, five years later... I was initially reluctant to mess with the diagnostics menu and found the small picture hard to see the detail on, but the basic principle was effective: I looked at the output port for the ink and it was dry, so I entered the diagnostics mode as described and ran the motor test on the black (K) cartridge for 30 seconds. Well, it turned out to be about a minute, because I couldn't figure out how to "scroll to Exit Mode": trying to scroll with the up and down arrows didn't work. The motor started making a horrible rattling noise after about 20 seconds and I was afraid it was broken. I eventually turned off the printer and turned it back on to restart and get out of the diagnostics menu. That worked. The next page I printed looked the same as before: faded black, but the 2nd one and the rest after that are beautiful!
Worked on my 6500. Thanks!
Have had similar problem with another 6505 after only about 4500 images. This solution worked just great. Tried changing cartriges but to no effect before. Thanks so much !
Thank you for your link. It worked for me also after attempting numerous other suggestions.
