SC-B9580 User's Guide Problem Solver Check pattern does not print correctly. The Prints Are Not What You Expected Print quality is poor, uneven, too light, too dark, obvious graininess, or the tone differs. 105 o Perform Print Adjustments. There is a slight gap between the print head and the media, so the landing sites for the different colors of ink may be displaced by the following causes. ❏ Difference in the direction the print head is moving (right to left or left to right) ❏ Temperature and humidity ❏ Inertial force of movement of the print head Displacement of the landing sites of the ink may cause the print results to show obvious graininess or to appear out-of-focus.
Also, large discrepancies in the feed amount cause banding (horizontal banding, tint unevenness, or stripes). You can adjust discrepancies in ink landing sites and the amount of media that is fed by doing Print Adjustments. Perform Automatic Adjustment in Media Settings and adjust according to the media being used. U “Optimizing Media Settings (Print Adjustments)” on page 47 o Perform head cleaning. The nozzles may be clogged. Print a check pattern again after performing head cleaning. U “Head Cleaning” on page 72 o Has the printer been left unused for a long time? If the printer has not been used for a long time, the nozzles may have dried up and have been clogged.
Steps to take when the printer has not been used for a long time U “Notes when not using the printer” on page 25 o Are you using a genuine Epson ink supply unit? This printer is developed for use with genuine Epson ink supply units. If you use non-Epson ink cartridges, printouts may be faint, or the color of the printed image may be changed because the remaining ink level is not correctly detected. Be sure to use the correct ink supply unit. o Are the print head nozzles clogged? If the nozzles are clogged, specific nozzles do not fire ink and the print quality declines. Try printing a check pattern. U “How to Print a Nozzle Check Pattern” on page 72 o Are you using an old ink supply unit?
The print quality declines when an old ink supply unit is used. Replace the old ink supply unit with a new one. Use all of the ink in the ink supply unit before the date printed on the package or within a year of installing the ink supply unit in the bulk ink solution, whichever is sooner. o Are the heaters at the correct temperature? Raise the temperature if the print results are blurred or smudged or the ink clots. Note, however, that raising the temperature too high can cause the media to shrink, wrinkle, or deteriorate. In addition, the heaters may require some time to reach the desired temperature if the ambient temperature is low.
The heaters may also not have the desired effect after reaching the selected temperature if the media is too cold. Allow the media to warm to room temperature before use.
