Epson Stylus Pro 7800 and 9800 5. Press the d button until PWR CLEANING is highlighted, then press Menu. Press Menu again, then press to start the power cleaning. 6. Follow the instructions on the LCD display to raise or lower the ink levers. 7. When cleaning is finished and the Pause light stops flashing, print the nozzle check again to confirm that the head is clean. For effective cleaning, always run a nozzle check between cycles. If the pattern is still missing segments or has deflections after a power cleaning cycle, turn the printer off and leave it overnight. Then clean the print head again the following morning with regular cleaning cycles. If you still see no improvement, contact Epson for assistance. Aligning the Print Head Aligning the print head is the most important thing you can do to ensure the best print quality. If banding appears on your prints, if they look grainy or blurry, or you see misregistration or "ghosting," you may need to align the print head. Although you can align the print head using the printer utility software, it's also easy to align from the control panel. This will do the most thorough job in the shortest time, and it's all automatic. If you haven't already done so, it's a good idea to run a nozzle check before aligning the print head (see page 6). This ensures that the print head alignment patterns print correctly. Follow these steps to align the print head using the control panel: 1. Make sure the printer is turned on. Then load Epson Enhanced Matte, Doubleweight Matte, Premium Luster Photo paper, or the paper that came with the printer. 2. Press the Menu button. 3. Press the d button until HEAD ALIGNMENT is highlighted, then press Menu. PAPER THICKNESS is highlighted. 4. Press Menu. The STANDARD setting is selected by default. This is the correct thickness setting for most Epson papers. 5. Press to save the setting. 6. Press l, then press d to highlight ALIGNMENT. 7. Press the Menu button to highlight AUTO, then press Menu again. UNI-D (uni-directional) is highlighted. This is the type of alignment to start with. 8. Press the button to start the alignment process. Each head alignment takes about 7 minutes. The printer's white beam sensor reads the alignment pattern and adjusts the printer automatically. Make sure you don't open the front cover or turn off the printer during this process. 9. When the uni-directional alignment is finished, press the d button until BI-D 2-COLOR is highlighted. Then press the button to start the bi-directional black alignment process. 10. When the bi-directional black alignment is finished, press the d button until BI-D ALL is highlighted. Then press the button to start the alignment process. 11. When done, press the Pause button to exit head alignment mode. If you want to verify or fine-tune the automatic alignment process, you can perform a manual head alignment. See your electronic Reference Guide for instructions. Replacing the Cutter Blade If you notice that your paper isn't cut cleanly, the cutter blade may need to be replaced. For a list of media that are not recommended for use with the cutter, see the Printer Guide. You can check the status of your cutter by printing a status sheet. See page 5 for instructions. You can obtain a new cutter blade from Epson (part number C12C815291). Removing the Old Blade 1. Press the Menu button. 2. Press the d button until MAINTENANCE is highlighted, then press Menu. 3. Press Menu again to select CUTTER REPLACEMENT. 4. Press the button. The print head moves to the replacement position. OPEN FRONT COVER TO SEE CUTTER REPLACEMENT LABEL is displayed. 5.
