Access the internal maintenance mode by pressing the Menu/Set button, then press * 2 8 6 4 within 2 seconds. This should put you in the maintenance mode menu. Enter 80, then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is over 6000, enter 2 7 8 3.

This will reset the purge count value. Then the printer will restart, try this step by step.without missing any thing. thanks

Usually this is caused by a foreign object or debris under the printhead path, or under where the printhead "parks."

Unplug the machine. Open the cover. Check the printhead path for little bits of paper, push pins, paperclips, staples etc. Note the location of the printhead.

If the printhead is at the far left, gently slide it towards the center (do not force it). Look carefully under where the printhead was stopped for debris. Use a flashlight if necessary.

Close the cover. Plug in the unit. Try again.

OK Try
Solution:

• Machine off
• Switch on the machine while holding down the “menu”button until all the leds are flashing on/off. Now you are in “maintenance” mode.
• Press 80
• Press the “mono start” button several times until you see “purge: xxxx”
• Press “2783” in order to reset the purge counter. You will see: “purge:0000”
• Press the "stop" button.
• Press “99” to exit the maintenance mode.

Hello there
I think this is down to a bit of paper sticking some where, it worth a try anyway.

This may work for you, it has worked for many here I given this advice so gave it a try it could work for you.
Generally when this happens, something has fallen into the printer, or a piece of paper has been jammed in there.

First step, remove the ink cartridge, and turn the printer upside down and gently shake it, see if anything comes out.

If nothing goes, or you can't hear anything rattling around, get a piece of cardstock paper (60lb or heavier) and gently push this through the printer, to see if it will help push out what might be stuck in there.
And gave the rode that the ink slides on a good clean and maybe a bit oil on cloth and wipe the rod with it.

Also clean The purge unit, called a spittoon assembly in an HP, Lexmark, Caonon and other inkjet printers, is where the print head assembly parks when not in use, also its other job is to clean and make sure the print head is clean and open for printing.

That is where you'll find the print head assembly parked on top of it.
It also has an electrical pump to milk the print heads and test for ink flow.

So clean all under where the heads are parked and on IP6600D models you can take out the heads just by clipping them out, and then clean well.


Please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.
