HP DesignJet Z5600 - Lines are blurred; Line lengths are inaccurate

1. Check that you are using appropriate print-quality settings. See Printing on page 50.
2. Reseat the printheads by removing them and then reinserting them. See Remove a printhead
on page 105 and Insert a printhead on page 108.
3. Align the printheads. See Align the printheads on page 153.
Lines are blurred
Humidity can cause ink to soak into the paper, making the lines blurred and fuzzy. Try the following:
1. Check that your environmental conditions (temperature, humidity) are suitable for high-quality printing.
See Environmental specications on page 171.
2. Check that the paper type selected in the front panel is the same as the paper type you are using. See
View information about the paper on page 42.
3. Try changing to a heavier paper type, such as HP Heavyweight Coated Paper or HP Super Heavyweight
Plus Matte Paper.
4. Select a paper type that is slightly thinner than the paper you have loaded; this will persuade the printer
to use less ink. Here are some example paper types in ascending order of thickness: Plain Paper, Coated
Paper, Heavyweight Coated Paper, Super Heavyweight Plus Matte Paper.
5. If you are using glossy paper, try changing to a dierent type of glossy paper.
6. Align the printheads. See Align the printheads on page 153.
Line lengths are inaccurate
If you have measured your printed lines and nd that the lengths are not suiciently accurate for your
purposes, you can try to improve line length accuracy in the following ways.
1. Print on HP Matte Film, for which your printer's line length accuracy is specied. See Functional
specications on page 169.
Polyester lm is about ten times more dimensionally stable than paper. However, using lm that is
thinner or thicker than HP Matte Film will reduce line length accuracy.
2. Set the Print Quality slider to Quality.
