HP Designjet 4500 Printer series - Manual (Page 278)

Try the following suggestions to avoid this problem:
● Use a recommended paper type (see Supported paper types).
● If the image you are printing contains intense color, try using HP Heavyweight Coated Paper.
● Use extended margins (see Adjust the margins), or try to increase the margins by relocating the
image within the page using your software application.
● If necessary, try changing to a non-paper-based material such as transparent film.
Smears or scratches on the front of glossy paper
Glossy paper may be extremely sensitive to the bin or to anything else that it contacts soon after
printing. This will depend on the amount of ink printed and the environmental conditions at the time of
printing. Avoid any contact with the paper surface and handle the print with care.
Hint Leave a sheet of paper in the bin so that freshly-printed sheets do not make direct
contact with the bin. Alternatively, you can remove an important print as soon as it emerges
from the printer, without allowing it to fall into the bin.
Ink marks on the back of the paper
Ink residues on the platen or on the input rollers are likely to mark the back of the paper. See Clean
the platen and Clean the input rollers.
Ink marks when the stacker is in use [4500]
NOTE The stacker is available with the HP Designjet 4500 Printer series only.
Try the following suggestions:
● Clean the stacker roller. See Clean the stacker rollers.
● Check that the paper you're using is compatible with the stacker. See Using paper with the
stacker [4500].
● When printing in Fast mode on Translucent Bond, Vellum, or Natural Tracing Paper, there could
be some ink transfer marks in highly inked areas. Select Normal or Best mode to avoid this
problem. See Change the print quality.
A defect near the start of a print
There is a type of defect that affects only the start of a print, within 5.5 cm of the leading edge of the
paper. You may see a thin or thick band of inconsistent color:
