I would try using something like rubber renew on the pickup rollers and make sure that the paper is being fed correctly. If this is happening then start looking at the ink.

Open the printer and remove the ink. Clean around the ink carriage and the under the ink with alcohol and a cotton swab. Pay special attention to areas with copper contacts. Some printers will let you re-run a cleaning utility from their system menu or the computer printer properties. Keep in mind too that some printers will not print correctly, even with full ink, if the exact type of ink it expects you to have is not installed. If all else fails change out the ink, but double check that the ink is correct against the manual or written instructions inside the printer. Not every cartridge that fits the printer necessarily is the right type and using the wrong ink can cause unexpected results.
