Lexmark X4650 cartridge carriage contact problem.

[Copy link]

Post time: 2012-8-3 08:15:17 |Show all posts
I have a Lexmark X4650 printer. Recently, it has been giving me an alignment error whenever I try to align the cartridges. When I align with only a black cartridge, everything works perfectly. But when both cartridges (or just the color cartridge) are in the printer, the color parts of the alignment page are partially incomplete. The color cartridge still prints, but not well.

The problem is not the cartridges. I have brand new cartridges, there is no tape on the cartridges, etc. The problem is the printer. You see, the metal contacts on the part of the cartridge cradle of the printer that touch the metal contacts on the color cartridge are damaged or stained or something. The contacts for the black cartridge are all right.

Here are two photos of the cartridge cradle, with both chambers for the cartridges open.

Picture 2

If you look carefully at the contacts in the chamber on the right, (The one for the color cartridge), you can see that there is some sort of black stuff on some of the metal contacts on the top. I don't know what it is, nor how to fix it. I thought it might be ink, and tried cleaning it with a Q-tip with alcohol on it, but it didn't remove any of it. I then considered that the black stuff might be some sort of corrosion.

Does anyone here know what it is, and how to fix it?
