There are horizontal lines or streaks across my image. Horizontal lines or streaks across an image is called banding. Banding can signal that the nozzles in the print head have become clogged, the print head needs cleaning, the print head needs to be aligned or that your media/paper setting is incorrect. Remove your print head and blot the bottom with a lint free cloth and warm, distilled water. If this does not resolve the problem, perform a Nozzle Check Pattern test. If lines are broken or missing, a print head cleaning is needed. See How do I clean my print head? If the Nozzle Check Pattern test results are normal but your images still show banding, check that your media/paper setting is correct. If that is not the cause of the problem, perform a print head alignment. Certain colors are not printing or are not printing correctly. Examine your image closely to identify which colors are either printing incorrectly or missing. Check to see that the affected color ink cartridge isnt empty, tainted, air-locked or inserted improperly. You will know that a cartridge is air-locked if it isnt empty and tapping it gently on a paper towel doesnt release any ink. Air-lock can occur when the vent hole located on top of the cartridge is blocked or clogged. This is sometimes the result of refilling your cartridge or if the cartridge wasnt stored in an upright position. The air-lock can often be released by simply turning the cartridge upside down but you may have to pierce the vent hole to release the air lock. The vent hole is located in the middle of the cartridge top, over the sponge. Perform a Nozzle Check Pattern Test. If lines are broken or missing, a print head cleaning is needed. If your ink cartridges are not empty, tainted, air-locked or inserted improperly and the Nozzle Check Pattern Test is without broken or missing lines, edit your image to compensate for the difference in color. Sometimes colors dont print as they appear on the computer screen. For example, if red is printing too orange, try reducing the amount of yellow in the red areas of your image or changing the shade of red until the printed image is acceptable. Print small test images on regular paper. My image is printing off the frosting sheet. When editing and printing your image, be sure to take into consideration the size and shape of your frosting sheet. When sizing your image, do not exceed the size of your frosting sheet. Center the image if needed. Always perform a print preview. Print practice pages on regular paper using draft quality. If your image is still printing slightly off the frosting sheet, performing a print head alignment may solve the problem. My printer tries to print but no ink is coming out. Check that your ink cartridges are not empty and that they are inserted properly. If they are, the problem is most likely a clogged print head. A print head cleaning is needed. See How do I clean my print head? Experiencing poor print quality in general. Reasons for poor print quality include clogged nozzles/print head, empty ink cartridges, low image resolution, improper media/paper setting and/or improper print quality setting. To improve print quality: Check to be sure your ink tanks arent out of ink. Perform a Nozzle Check Pattern test to check for clogged nozzles indicated by broken or missing lines. Perform a print head cleaning if needed. Check media/paper setting and print quality setting. You can find the proper settings for your printer here. Poor print quality can also be the result of printing low resolution images. If youve enlarged an image, this can result in low resolution. Print images with a higher resolution.
