Test Print Examples (Continued)
4: Reverse Text
The print indicates if the printhead is producing
properly-sized drops of ink and that the drum
temperature is not too high.
NOTE:
This print should be made with the
system covers closed and in place. The
heat loss without the covers can hide the
"too-hot" thermal problem. Also print the
test print in Enhanced print mode.
Look for: Legibility in the lines of 6-point text,
particularly in the primary colors. If the letters
are closed or badly "plugged" with ink, the
printhead is laying down too much ink. A good-
quality print shows five vertical parallel lines of
different thicknesses on the left and right side of
the print. If the thinnest line is missing, the
printhead is outputting too much ink or the drum
temperature is too high.
Causes:
NOTE:
Ensure that the system is not in High
Resolution/Photo or Standard print
mode.
Check the thermal regulation of the printhead
and of the drum. Make sure that the drum
temperature sensor is correctly mounted and in
proper, even contact with the drum. If
necessary, remove the sensor and check it for
an accumulation of debris at its contact point.
Replace the drum temperature sensor.
Ensure the printhead drive voltage is set to the
default 128.
