（3）The powdered carbon is too full.

Why does the print documents repeat appear smudge?

Why does the print documents repeat appear smudge?

   The inkjet printer repeated contamination is due to ink tank or ink tube caused by leakage of ink;When the nozzle performance is poor,The ejected ink and the remaining ink cannot be disconnect and are in a balanced state,And there will appear leakage phenomenon;And the laser printers such a phenomenon there's a certain regularity,As a sheet of paper passes through on the printer,maybe it caused by  dirty or damaged roll.

CLX-6220 Jam in Exit Area

CLX-6220 Jam in Exit Area

    We have a CLX-6220 with a consistent exit area jam. The paper continuously jams in the exit area only. Now, the symptoms of this are a consistent rhythmic clicking like a door is moving. I seem to remember this sound NOT being there except only once in the process of printing a page. The jam seems to fold the paper in the exit area and end up not being ejected. I have to lift the scanner/display level and then once inside I have to lift a black plastic guide to get at the paper. The paper will be stuck at the bottom row of grey rubber rollers next to a slot leading to the inside of the printer. Any idea what this is and what it may take to fix this particular problem. I would hate to see this enterprise class printer go to waste.About 90% of prints jam in the exit area with the paper. It seems to be much worse when printing duplex or more than one page. I suspect it may be a problem with whichever part sends the paper to either the duplex unit or exit area, but I have been unable to identify it.

    I believe this is from a bent myler guide. essentially its a clear piece of plastic that help the paper make sharp turns, however when you pull the paper out the wrong way after a jam, then the guide bends and now the paper runs into it, you have to get it replaced. The problem is due to a electromagnetic clutch which actuate the lift at exit. Under the core of solenoid it is a small piece of sponge which reduce the noise and keep the plate at a small distance from core . That sponge become sticky and work worse.Put a piece of thin plastic on the face of the core and a little piece of duck tape under the sponge. 

What are the reasons for text isn't obvious? How to deal with it?

What are the reasons for text isn't obvious? 

How to deal with it?

The reason:
The toner, magnetic roll developing voltage and carbon power is low, effect of photosensitive is poor .
The resolution is doesn't meet the printer requirement.
The printer has been working too long and it's tired.

Solution:
shake out the toner cartridges, if the printing effect is not improved, please replace the toner cartridges.
Test the resolution and meet the printer requirements.
Arrange the printing interval to restore the performance of the light-sensitive drum.
Clean the photoelectric components in the printer.
