Puddling the Cap
It is recommended to do this procedure every 3-6 months, or whenever you experience a decline in cleaning efficiency. If you have never done this procedure before, repeat it several times in succession to soften up the capping pad. Lines through nozzle checks, clogged nozzles and “missing” colors on your nozzle check can usually be solved with this procedure.
1. Open the main window/door
2. Press down on the cutter and move the carriage to the left
3. Locate the capping pad. It should be a multi-color fabric pad, usually orange and black.
4. With an eyedropper of tap water, soak the pad to the point of spill over.
5. Allow the water to be absored (3 minutes should do the trick)
6. Repeat, and return the carriage to it’s home position while still wet
7. Wait 3 minutes for absorption
8. Run a standard clean cycle (not power clean)
If you still experience trouble, try the following:
A. After step 2, lay down a half-folded wet paper towel (do not fold more than once as this will be too thick) in the carriage path
B. Run the carriage over the paper towel and center it
C. Grab the edges of the paper towel and “shimmy” the back of the carriage. This will wipe off some of the more stubborn dried ink chunks around the edges of the print head. *Be careful not to tear the paper towel as this can leaves hard to remove pieces of paper towel lodged in the back of the carriage.
D. Continue with step 3 in the “puddling the cap” procedure.
E. After step 5, reach in and locate the rubber wiper blade.
F. Wipe the blade with a damp paper towel until clean.
G. Finish the “puddling the cap” procedure"
