Paper is not Flat
Description of problem
If the paper does not lie flat when it comes out of the Printer, but has shallow
waves in it, you are likely to see visible defects in the printed image, such as
vertical stripes. This can happen when you use thin paper that becomes
saturated with ink.
Shown below is an example of what you might see if you have problems
with the paper not being flat:
Corrective Action
1 Try using a heavier paper type. When printing dense colors, it is
recommended to use HP Heavyweight Coated Paper or HP Productivity Gloss.
2 Make sure that only genuine HP paper is being used.
3 Check that the appropriate print quality settings are being used.
Refer to
Page 6-3 for further information on choosing the correct Print Quality settings
.
4 Check that the environmental conditions (temperature, humidity) are within
the temperature/humidity range as specified for the Printer (refer to the
User’s Guide for further information).
