7.2.12 Cleaning the Head Nozzle Face
If the nozzles are clogged by paper dust or foreign matter clinging to the Head
Nozzle Face, use the following procedure to remove it.
Caution:
Be careful not to touch the nozzle face directly with your fingers
otherwise normal ejection may not be possible.
Step 1 : Turn off the Power Switch and return the Head to the home position.
(The Power Cable may remain connected)
Step 2 : Open the Front Cover and remove the Plotting Board and Front Paper Guide
(You will need a short Phillips screwdriver to remove the Plotting board.)
Step 3 : Bring the Head to the printing area.
Step 4 : Soak a lint-free cloth in water or distilled water and gently wipe the Head Nozzle Face.
(Lint-free cloth is closely woven from extremely fine threads and has no nap and produces no
dust.)
Caution:
Don’t wipe with fluffy cloth or tissue paper as these tend to
make the clogging worse.
Be careful not to rub the nozzle face too hard.
Step 5 : Return the Head to the home position.
Step 6 : Refit the Plotting Board and Front Paper Guide.
Step 7 : Turn on the Power Switch and print out a diagnostic pattern. If there are no dots missing from the
G-line step pattern, the task is completed.
If some dots are missing, repeat Steps 1 to 7.
