Receiving error code 5100. what to do?

Hi You can Try 2 things.

ERROR 5100 means that there is some foreign object blocking your cartridges carriage that disables it from moving. 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


Next try.

It may be a piece of paper or a scotch tape or a staple wire.
Solution 1:
Clean the timing strip.

Solution 2:
The purge cap (the white sliding mechanism that the print head parks to when it's not in use) may be not lubricated well enough .

Lubricate the sliders with some white grease (don't get it on the small wipers or the black caps); this repair probably require to remove the right panel off of the printer to gain access to the purge mechanism.

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.
