Have you tried cleaning the document feeders Scan Glass? (small glass under doc feeder ~ 1" by 9") Most times there is dirt spot on this glass, causing a shadow on scans and copies.
Try copying from the large glass by lifting doc feeder / platen cover and manually placing original. If no line copying or scanning manually from large glass, then small scan glass is deffenitely the culprit. Hope this helps.

The reason why the printer refuses to print if you get low on one or more colors is that the system runs off negative pressure through the ink lines to the print head. If you were able to continue printing with an empty cartridge you could get air in the respective ink line, disrupt the negative pressure, make it so that that color will no longer print, and require you to get the printer serviced to fix the problem. I own a Cartridge World ink refilling store and I feel this is a good machine (compared to some of the others out there). The only down side with this type of machine is the print heads expiring or getting clogged as you are experiencing. The reason the black is clogged and not the other colors is that the black ink is pigment based and the colors are dye based. The pigment based inks do tend to clog print heads over time. You can try to rehydrate the print head with warm distilled water. if you can't get it working to your satisfaction you can buy a new black/yellow print head for $72. With this type of printer you should print at least one black and white and one color document per week to keep the print heads fresh. If they sit too long without ink flowing through them then they can get clogged and print poorly. I hope this helps belay some of the resentment you hold towards your printer.

Hi There
Summary
Usage of compatible ink and leave the printer idle too long may cause printhead clogging
What should you do if you get this problem. Relax; you may recover the printhead by unclogging it. Follow these steps to unclog the printhead

1. Right click in the printer driver name
2. Select Properties menu
3. Click Maintenance tab
4. Click on cleaning sign for regular cleaning. Perform this up to 3 times.
5. If this does not work, perform Deep Cleaning

And if that not work

Some times it needs a good clean up but this is up to you if you want to do this,
But after you done this prime the printer so it gets the inks back in the heads, it may take a little time for the inks to work.

Ok.

There is fluid cleaner for this but I can never find any in the shops the only ones I seen is when they sell them in Tesco but they come in with the ink refill bottles so I just use worm water by it self on a cloth and dabbing on the heads to clean them, it will not harm the heads but not to much water.

Some heads are on the inks them self but some have them inside the printer so I not know your printer so if the heads are inside you need to get them out you may find that some heads will just clip out put some need to be unscrewed so you got to know how they come out so be careful and not push to hard on them, if the heads are on the ink then it is a easy job to clean them,
It worth a try it worked for me more than ones.

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