To identify if the image drum is the problem, insert an image drum from another HP Color LaserJet
CP6015 series, if one is available, before ordering a new image drum.
If the defect repeats at 94.0 mm (3.75 inch) intervals, try replacing the image drum before replacing the
fuser.
Overhead transparency defects
Overhead transparencies might display any of the image quality problems that any other type of paper
could display, as well as defects specific to transparencies. In addition, because transparencies are
pliable while in the print path, they are subject to being marked by the paper-handling components.
NOTE:Allow transparencies to cool at least 30 seconds before handling them.
●On the printer driver’s Paper tab, select Transparency as the paper type. Also, make sure that
the tray is correctly configured for transparencies.
●Check that the transparencies meet the specifications for this product.
●If transparencies are sticking together in the output bin, set MEDIA TEMP to REDUCED from the
print quality menu. See 
Use manual print modes on page 243.
●Handle transparencies by the edges. Skin oil on the surface of transparencies can cause spots
and smudges.
●Small, random dark areas on the trailing edge of solid fill pages might be caused by transparencies
sticking together in the output bin. Try printing the job in smaller batches.
●If the selected colors are undesirable when printed, select different colors in the software program
or printer driver.
●If you are using a reflective overhead projector, use a standard overhead projector instead.
Print quality problems associated with the environment
If the product is operating in excessively humid or dry conditions, verify that the printing environment is
within specifications. See 
Environmental specifications on page 269. Several optimization modes can
also help with environmental conditions. See 
Use manual print modes on page 243.
Print quality problems associated with jams
●Make sure that all paper is cleared from the paper path.
●If the product recently jammed, print two to three pages to clean the product.
●The paper does not pass through the fuser, causing image defects to appear on subsequent
documents. Print two to three pages to clean the product.
Optimize and improve image quality
The following procedures can be used to solve most image quality problems.

							Use manual print modes
Try the following manual print modes to see if they solve the image quality problems. These options can
be found in the Optimize sub-menu under the control panel Print Quality menu. See 
Print Quality menu
on page 22.
●PAPER CURL: The REDUCED setting decreases full speed to 10 PPM (instead of 40 PPM) and
3/4 speed to 7.5 PPM (instead of 30 PPM) in order to reduce paper curl problems.
●PRE-ROTATION: Set this feature to ON if horizontal streaks appear on pages. Using this feature
increases the warmup time for the product.
●FUSER TEMP: If you are seeing a faint image of the page repeated at the bottom of the page or
on the following page, you should first make sure the Paper Type and Print Mode settings are
correct for the type of paper you are using. If you continue to see ghost images on your print jobs,
set the Fuser Temp feature to one of the Alternate settings . Try the ALTERNATE 1 setting first
and see if it solves the problem. If you continue to see the problem, try ALTERNATE 2 and then
ALTERNATE 3. With the ALTERNATE 2 and ALTERNATE 3 settings you may see an extra delay
between jobs.
●TRAY 1: Set the mode to ALTERNATE if you are seeing marks on the back side of the paper when
printing from Tray 1. This increases the frequency of the cleaning cycle.
●GLOSS MODE: Set this feature to HIGH for glossy print jobs, such as photos, if you notice the
gloss finish decreasing after the first page is printed.
●LIGHT MEDIA: Set this feature to ON if you are frequently seeing Fuser Delay Jam or Fuser Wrap
Jam messages, especially when printing on light-weight paper or on jobs with heavy toner
coverage.
●MEDIA TEMP: Set this feature to REDUCED if you are having problems with paper sticking
together in the output bin.
●ENVIRONMENT: Optimizes performance in extreme low temperature environments. Set this
feature to ON if the product is operating in a low-temperature environment and you are having
problems with print quality such as blisters in the printed image.
●LINE VOLTAGE: Optimizes performance in low-voltage conditions. Set this feature to ON if the
product is operating in a low-voltage environment and you are having problems with print quality
such as blisters in the printed image.
●CLEANING FREQUENCY: If you are seeing defects in the printed output that repeat at 38 mm
(1.5 inch) intervals, set this feature to ALTERNATE. This feature increases the frequency at which
the C roller is cleaned. Setting this feature to ALTERNATE might also reduce printing speed and
increase the frequency of consumable replacement.
●D-BLADE BIAS: If you are seeing short white vertical lines in the printed output, set this feature
to ALTERNATE. The ALTERNATE setting might also cause dark spots in the printed output, so
be sure to test this setting on a few print jobs.
●WASTE BIN: Set this feature to ALTERNATE if you are seeing lengthwise toner streaks in your
printed output, especially in jobs with low toner coverage.
●BACKGROUND: Turn this feature on if pages are printing with a shaded background. Using this
feature can reduce gloss levels.
●HEAVY MODE: Sets speed to 30 PPM
 or 24 PPM in order to better feed heavy paper.
