I use my Phaser 5550 pretty heavily (up to 7000 pages in a job). Recently I have found that the drum cartridge begins to fail early: it prints faded black text (looking more grey than black) when there are still 40,000 pages left on the drum's life.
This has happened with two drums in a row. I know it is the drum, not the toner, because the problem was solved when I changed the drum (until it went wrong again) - and new toner doesn't make a difference.
Why is this? It could be that I am using the printer too heavily - but I doubt this is the reason. I have researched the way the recommended usage is calculated, and apparently the drums last longer when used for long jobs rather than short ones.
Does anybody know the answer? Is there anything I can do to solve the problem? I can't afford a new drum every 20,000 pages!
Thank you in advance for your help.
