We have a Kodak i4000 scanner. We replaced the tire assembly on the feed module and separation roller. Now we are getting a U7 message and the elevator is not going up.

SOURCE: Pixma i4000 - manual feed picks up 2 to 3 sheets at a time

Get a window cleaning product such as windowlene and a soft but LINT FREE cloth. Remove any paper from the feeder and turn off the machine

Look into to sheet feeder and identify any rubber areas. There should be a rubber pick up wheel and just beyond it a separator pad. There may also be a cork pad in the vicinity.

Use your cloth well dampened and clean all these item as best you can. You can rotate the wheels but ensure you go the correct direction and do not force anything that does not want to move. This will be chore as access is only easy for pixies. Once you have then cleaned and dried off, replace the paper and restore the power.

Try running a print job and see if it makes much difference. If it helps, then you will know that the pick up wheel and separator pad are worn out and could do with replacing.

The paper jam error is related to this issue as the printer is expecting the leading edge of the paper to pass its sensor and then 297mm later the trailing edge should pass the same point. If the machine feeds more than one sheet, the chances are that the paper length will be altered and the machine thinks a bit has been left behind.

Let me know how you get on

Thanks to the Konica Minolta tech: Solution is to use alcohol and a clean wipe or cue-tip on the grey 1/2 moon roller deep inside at the end of the paper feed tray. It is accessessible easily by lifting blue top cover of printer, then pulling out the ink cartridge. There will be a grey 1/2 moon like roller seen when looking at very bottom of cavity. Clean the dust off and all will work fine. You can manually roll the roller to get all faces. The machine will reset it's position so it is not nessary to set back to original position.       Turn the machine on with or without paper. Once the roller has reset it's position, gently push the load of paper into the paper tray to be sure the roller was not keeping the paper from being placed to furthest position toward back of tray.
     All is ready for reliable printing once again! Best regards, Danny

Hello there
You may still have a little bit there some where 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.
