HP PageWide Enterprise Color, HP PageWide Managed Color - Media guide (white paper)

10
Issues and recommended actions
The following table shows a list of possible issues that may be related to paper quality, how you load paper into
the tray, or how you set the paper type on the control panel or in the software driver. Some issues may simply be
the result of unrealistic expectations. For example, 16 lb (60 g/m
2
) papers tend to have much more strike-through
and may not be suited to duplex printing.
Issue
Recommended action
Output is wet to touch
Longer drying times can be caused by certain papers, high concentrations of ink in printed areas, and high-
humidity environments.
• Papers with ColorLok Technology dry faster. You might need to use heavier papers such as 24 lb (90 g/m
2
) or
32 lb (120 g/m
2
), which can absorb more ink and hence dry faster.
Wrinkles in printed areas
(called cockle)
Excessive cockle is caused by a problematic combination of printed areas of high ink concentration and low-
humidity environments.
• Lighter weight papers cockle more, so consider using heavier weight papers.
• Papers with ColorLok Technology tend to cockle less than non-ColorLok papers.
Paper Curl
Paper curling can occur depending on the interaction of paper and high concentrations of ink in printed areas.
• Changing to a different paper can change the curl behavior.
• Consider reducing the amount of high concentrations of ink. Methods to reduce the ink concentration are:
– Printing in General Office mode
– Adjust the ink levels in the printer driver.
i. Go to “Printer Properties” and select the Advanced tab.
ii. Select “Ink Setting” and use the “Saturation” slider to reduce the amount of ink printed.
Note: In some driver versions “Ink Settings” are located in the “Color” tab.
– Print using the Light Media type setting.
Strike-through
Excessive visibility of the printed image from the back side of the sheet is due to paper that has low
opaqueness or is too thin.
• Consider using a heavier paper.
• Consider using paper with ColorLok Technology as it is specially formulated to keep ink pigments on the
surface of the paper instead of bleeding into the paper itself.
Smeared ink on glossy paper
There are many coated (glossy) papers such as LaserJet Glossy Papers that do not work in this device. The ink
cannot absorb into the media and creates a wet, messy output. Fortunately, this condition can be avoided:
• Never use LaserJet Glossy paper.
• Never use coated paper developed for offset printing.
• HP Recommends HP Brochure Paper Glossy, 48 lb (180 g), which can be printed on both sides and is
reasonably priced.
• If you do print on LaserJet glossy paper or other paper that does not let ink absorb into the paper, recover as
follows: – Remove and discard smeared paper, then clean ink off the surface of the output bin using a clean,
moist cloth.
Highlighter smears ink on
printed page
Good highlighters will not smear ink on the printed page when using one pass of the highlighter.
• Use a single pass when highlighting your printed documents.
