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 specifications on page 193. 2. Check that the paper type selected in the front panel is the same as the paper type you are using. To check on the front panel, use the View information key . 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 different type of glossy paper. 6. Align the printheads. See Align the printheads on page 55. Line lengths are inaccurate If you have measured your printed lines and find that the lengths are not sufficiently 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 specified. See Functional specifications on page 191. Polyester film is about ten times more dimensionally stable than paper. However, using film that is thinner or thicker than HP Matte Film will reduce line length accuracy. 2. Set the Print Quality slider to Quality. 3. Maintain the room at a steady temperature between 10 and 30°C (50 and 86°F). 4. Load the roll of film and let it rest for five minutes before printing. 5. If you are still not satisfied, try recalibrating the paper advance. See Perform paper advance calibration on page 30. 146 Chapter 16 Troubleshoot print-quality issues ENWW

Lines are blurred

Humidity can cause ink to soak into the paper, making the lines blurred and fuzzy. Try the following:

Check that your environmental conditions (temperature, humidity) are suitable for high-quality printing.

Check that the paper type selected in the front panel is the same as the paper type you are using. To check

Try changing to a heavier paper type, such as HP Heavyweight Coated Paper or HP Super Heavyweight Plus

Matte Paper.

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.

If you are using glossy paper, try changing to a diﬀerent type of glossy paper.

Align the printheads. See

Line lengths are inaccurate

If you have measured your printed lines and ﬁnd that the lengths are not suﬃciently accurate for your purposes,

you can try to improve line length accuracy in the following ways.

Print on HP Matte Film, for which your printer's line length accuracy is speciﬁed. See

Polyester ﬁlm is about ten times more dimensionally stable than paper. However, using ﬁlm that is thinner

or thicker than HP Matte Film will reduce line length accuracy.

Set the Print Quality slider to

Quality

Maintain the room at a steady temperature between 10 and 30°C (50 and 86°F).

Load the roll of ﬁlm and let it rest for ﬁve minutes before printing.

If you are still not satisﬁed, try recalibrating the paper advance. See
