How to Clean the Head Nozzle Face
How to Clean 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 fin-
gers otherwise normal ejection may not be possible.
1. Turn off the Power Switch and return the Head to the home position.
(The Power Cable may remain connected)
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.)
3. Bring the Head to the printing area.
4. Soak a lint-free cloth in water or distiled 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.
CAUTION: Be careful not to rub the nozzle face too hard.
5. Return the Head to the home position.
6. Refit the Plotting Board and Front Paper Guide.
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.
