2. Dampen a small piece of clean linen cloth with a small amount of alcohol.
• Never use cotton, soft tissue, or any other type of material that could shred and leave fibers
on the encoder film strip.
3. Gently wipe the horizontal encoder strip always from right to left in one direction.
• To avoid bending the spring plate on the left end of the encoder strip, always wipe the strip
from right to left. The horizontal encoder strip is fragile.
• Never apply excessive tension to the horizontal encoder strip when cleaning it.
4. Push the carriage unit to the right with your hand.
5. Repeat the procedure to clean the left side of the encoder strip.
6. Lock the carriage.
7. Turn on the machine.
8. Confirm that the machine is in standby mode and ready to operate.
• Switch on the printer immediately after cleaning to ensure that the carriage returns to the right
side of the machine and caps the print heads.
• If this is not done immediately, the print heads may dry out.
9. Do the "Nozzle Check" after cleaning, and then check the patterns for missing or broken lines.
10. Do "Print Head Cleaning" if the pattern is not satisfactory.
11. Do "Print Head Flushing" if the pattern is not satisfactory, even after three print head cleanings.
12. Do "Print-Head Flushing" and print another Nozzle Check Pattern.
13. If the Nozzle Check Pattern is still not satisfactory after flushing the print heads, replace the
horizontal encoder strip.
