HP 2600n - Manual (Page 46)

Problem Cause Solution
An image that appears at the top of the
page (in solid black) repeats farther
down the page (in a gray field). Software settings might affect image
printing. In your software program, change the
tone (darkness) of the field in which the
repeated image appears.
In your software program, rotate the
whole page 180° to print the lighter
image first.
The order of images printed might
affect printing. Change the order in which the images
are printed. For example, have the
lighter image at the top of the page,
and the darker image farther down the
page.
A power surge might have affected the
device. If the defect occurs later in a print job,
turn the device off for 10 minutes, and
then turn on the device to restart the
print job.
Solving issues with color documents
This section describes issues that can occur when you print in color.
Table 6-14 Color document issues
Problem Cause Solution
Only black is printing when the
document should be printing in color. Color mode is not selected in your
program or printer driver. Select color mode instead of grayscale
mode.
The correct printer driver might not be
selected in the program. Select the correct printer driver.
The device might not be correctly
configured. Print a Configuration page.
One or more colors are not printing, or
are inaccurate.
Sealing tape might be on the print
cartridges. Verify that the sealing tape has been
completely removed from the print
cartridges.
The media might not meet HP
specifications. Use a different paper, such as high-
quality paper that is intended for color
laser printers.
The device might be operating in
excessively humid conditions. Verify that the device environment is
within humidity specifications.
One or more print cartridges might be
low. If you are using non-HP print
cartridges, no messages appear on the
device control panel or in the
HP Toolbox. Replace any low print cartridges.
The control panel is set for override. Replace low or empty print cartridges.
