Output that smudges easily indicates that the fuser needs replacing. Marks that appear in the same place (referred to as repetitive defects) are often due to dirty feed rollers (note that there are rollers in the toner cartridge and fuser unit too) or a damaged or dirty photosensitive drum. If a color is completely missing, try replacing the cartridge. If this does not solve the issue, clean the contacts between the printer and cartridge. This indicates that the primary charge roller is dirty or damaged or that the high voltage power supply to the developer unit is malfunctioning. Try printing with a known good toner cartridge. This is a sign that the photosensitive drum has not been cleaned properly. The drum is smaller than the size of a sheet of paper, so if the latent image is not completely cleared, it will repeat as a light "ghost" or dark "shadow" image farther down the page. Images may also appear from previous prints. Try printing a series of different images, and see if the problem resolves itself. If not, replace the drum/toner cartridge. Loose toner may be getting onto the paper. Clean the inside of the printer using an approved toner vacuum. This indicates either that the toner is poorly distributed (give the cartridge a gentle shake) or that the transfer roller is dirty or damaged. If prints come out in the wrong color (for example, if the whole print has a magenta tint), ensure that the toner cartridges have been installed in the correct location (for instance, that a magenta cartridge hasn't been installed in the cyan slot). Also ensure that there is sufficient toner in each cartridge. If there is a cast or shadow-like effect, the transfer belt or one or all of the cartridges or rollers are probably misaligned. Try reseating them, and then run the printer calibration utility and print a test page to verify the problem is solved. application or driver problem, but it could indicate that a toner cartridge has been installed without removing its packing seals. Alternatively, if these simple causes can be discounted, this could also be a sign that the transfer roller is damaged (the image transfer stage fails).
