Whole image is blurry or grainy
1. Check that the paper type you have loaded corresponds to the paper type selected in the front panel and in
your software. See View information about the paper on page 36.
2. Check that you are printing on the correct side of the paper.
3. Check that you are using appropriate print-quality settings (see Printing on page 38). In some cases, you
can overcome a print-quality problem merely by selecting a higher print-quality level. For instance, if you
have set the Print Quality slider to Speed, try setting it to Quality.
4. Print the Print Quality Diagnostic Report, and align the printhead if recommended in the report. See Print
Quality Diagnostic Report on page 68.
5. If the problem remains, perform paper advance calibration: see Recalibrate the paper advance on page 75.
If the problem persists despite all the above actions, contact your customer service representative for further
support.
Paper is not at
If the paper does not lie at when it comes out of the printer, but has shallow waves in it, you are likely to see
defects in the printed image, such as vertical stripes. This can happen when you use thin paper that becomes
saturated with ink.
1. Check that the paper type you have loaded corresponds to the paper type selected in the front panel and in
your software. See View information about the paper on page 36.
2. Try changing to a thicker paper type, such as HP Heavyweight Coated Paper.
3. Select a lower print quality (such as Speed); the printer will then use less ink.
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.
