Possibility cartridge print head dry.

Solution 1:
Do a clean process
cartridge automatically. Press START - Control Panel - Printers and Faxes - HP Deskjet d2360 right click and select Printing Preferences - Select the Color tab - select Printer Services - select Clean cartridge, wait for the cleaning process is completed - Perform Test print. If the print test results, has good graphics, press Finish. If the graph is not clear or drop out, repeat the cleaning process once again.

Solution 2:
1. Open the cover printer, cartridges will move to the middle position.
2. Remove the cartridge (be careful, do not touch the element cartridges or print head by hand), then stick the tip cartridge (print head) to clean water
3. Then, attach the print head to a tissue paper. If there is a tissue paper used in ink (black cartridges, black block lines, and color cartridges, three color red yellow blue lines), means the flow of ink to the print head is normal. If the
tissue paper no trace of ink, attach back into the water, repeat the above process.
4. After process is complete no.3, clean the cartridges with a tissue paper (careful, do not touch the element cartridges or print head by hand, because it will damage the cartridge). After cartridge clear of the water, insert the cartridges into printer.

My printer is printing blurry on the right hand third of the page - the rest is crystal clear

The printer's head with the ink cartridges runs on a rail above the paper path. The paper comes out face down so the left side of the printer prints the right side of the page. The bottom of the print cartridge is either too close or too far away from the paper. So look for something that is lifting the paper up like some paper wrapped around the rollers or something that would move the head up or down like a loose rail - it would be on the left side of the printer. If it is not paper or some other foreign material on the rollers or stuffed behind them (open the rear cover plate too), the chances are that it will not be cost effective to service the printer.

i think u should check for peices of paper ,tiny objects etc that might be obstructing the movement of the paper. also check that the print head is not disconnected from the belt you can check this by slidind the print head from side to side and ensure that both of them are moving hope this helps.

This sounds like a problem with the paper pick up rollers. I would suggest cleaning the rollers with a little isopropyl alcohol. Please make sure the machine is turned off when doing the cleaning. Let the rollers dry for a few minutes. If this does not work, The rollers would probably have to be replaced.

The ink well is full and leaking. How do I clean it out.

There is an ink well below the home run position of the print head and cartridge assembly. If you open the lid of the printer, the print head moves to the center of the rail. You then unplug the printer and gently move the print head to the left and out of the way. If you shine a flashlight in the right hand corner or home run position, you will see the ink well. You can clean it out with a paper towel or a syringe. Obviously, the well is no longer overflowing and the drip should stop.

It almost sounds as if the guide on the left side has been moved. Reload the paper so it is up against the right side of the paper tray and then move the left guide up against the paper.
