Print quality troubleshooting
Lines are Blurred (Ink Bleeds from Lines)
Description of problem
This problem is often caused by the ink soaking into the paper, making the
lines blurred and fuzzy. This could be because of the humidity in the air.
Corrective Action
1 Check that the environmental conditions (temperature, humidity) are suitable
for high-quality printing.
2 Make sure that the paper type selected in the Front Panel is the same as
the paper type loaded into the Printer.
3 Try using a heavier paper type. When printing dense colors, it is
recommended to use HP Heavyweight Coated Paper or HP Super
Heavyweight Coated Paper.
4 If glossy paper is being used, try changing to a different type of glossy
paper.
5 Align the printheads. See Image Quality Maintenance Procedure on page 1-
48.
