Available models differ depending on your region and product release dates�

Recommended Types of Calibration

The density and tone of colors may change as you print
large volumes of pages� Even if you are printing the same
image, slight variations in the shades of colors may become
apparent� This is characteristic to this machine� You need
to calibrate the colors periodically to compensate for the
difference in colors� The following two types of calibration
can be done periodically� Refer to the following and select
the type of calibration that meets your needs�

Simple Calibration Enhanced Calibration

or

If you want to calibrate the colors quickly and

1

easily*

If you want to calibrate the colors as precisely
as possible even if it takes time and effort

If the environment of the location in which
you have installed the machine is outside the
recommended range*

*1 You can select this type of calibration only if the environment in which the machine is installed is within the recommended range*2�

*2 For information on the environment (temperature and humidity) for installing the machine and storing paper, see the

Installation and Operating Environment Guidelines or the Specialty Media Handling Guide�

Recommended Types of Calibration

Other Types of Calibration You Can Do When You Notice Variations in the

Shades and Tones of Colors

The following calibrations can be made in addition to
Simple Calibration and Enhanced Calibration� Calibrate
the machine only if you notice irregularities in the
colors� (You do not need to calibrate the machine on a
regular schedule�) Make sure to do automatic gradation
calibration prior to doing either one of the following
calibrations� If you are using the imagePRESS Server and
a spectrophotometer, such as an X-Rite i1 Pro, you can
make more precise corrections by doing both Shading
Correction and Automatic Color Tone Correction� In
this case, do these corrections in the following order:
Automatic Gradation Calibration → Shading Correction
→ Automatic Color Tone Correction�

Shading Correction

Do this if the color densities become uneven�

Automatic Color Tone Correction

Do this if you notice differences in the color tones�

imagePRESS C850/C750/C650/C65

Simple Calibration

If you want to correct the printed colors quickly and easily, this type of calibration is recommended� Do steps 1 to
3 in "Calibration After the Machine Is in Operation" once a day� (p� 37) This is, however, done on the premise that the
environment (temperature and humidity) in which the machine is installed satisfies the recommended range� If the
environment does not satisfy this range, do "Enhanced Calibration�" (p� 5)

Prior to Starting Simple Calibration

See "Adjustment for Image Quality and Finishing
(Calibration)" > "Automatic Gradation Adjustment"
> "Changing Adjustment Level" in the User's Guide,
and set [Adjustment Level] for automatic gradation
adjustment to 'Same for All Paper Types'�

Recommended Types of Calibration

Enhanced Calibration

This type of calibration is recommended if you want to correct the shades and tones of colors as precisely as possible,
even if it takes more time and effort� This is also suitable if the environment (temperature and humidity) in which the
machine is installed does not satisfy the recommended range for some reason� This type of calibration uses specific
types of paper, which correspond to the types of paper you want to print on, so that more precise corrections can be
achieved� The paper is categorized in three groups, group A, B, and C, for the purpose of more precise calibration� See
the list in "Types of Paper You Can Use for Calibration" at the end of this document� Find out in which group the paper
you want to print on is categorized, and then select the corresponding type of paper you can use for calibration� To
keep making corrections precisely, calibrate the machine for the paper you are printing on whenever you print on
paper of a different group� For example, if you print on plain paper, which is listed in group A, in the morning, and print
on Heavy 5, which is listed in group B, in the afternoon, calibrate the machine for paper in group A (p� 6) before starting
printing jobs in the morning and calibrate the machine for paper in group B (p� 7) before starting printing jobs in the
afternoon�

Prior to Starting Enhanced Calibration

See "Adjustment for Image Quality and Finish
(Calibration)" > "Automatic Gradation Adjustment"
> "Changing Adjustment Level" in the User's Guide,
and set [Adjustment Level] for automatic gradation
adjustment to 'By Paper Type Group'� If you are not sure
of the name of the paper to use for calibration, contact
your local authorized Canon dealer�

NOTE

The density and tone of colors may change as you print large
volumes of the same pages, even if you are printing the same image,
slight variations in the shades of colors may become apparent� This
is characteristic to this machine� You need to calibrate the colors
periodically to compensate for the difference in colors�

This section explains how to perform calibration using [Adjustment
Level] with 'Same for All Paper Types' for automatic gradation
calibration� For more information on [Adjustment Level] for
automatic gradation calibration, see "Adjustment for Image Quality
and Finishing (Calibration)" > "Automatic Gradation Adjustment" >

Find the answers to your questions about how to solve your problems�

Q� Are the letters or lines too small or too thin?

A� If the letters or lines in the data you are printing are too small or too thin, the printed letters and lines

may appear faint�

Solution

If possible, modify the data you are printing to enlarge the text and make the lines thicker�

Q� Are you using an outline font?

A� Outline fonts become thicker when they are printed, and they look different from their images on

your computer screen�

Solution

•

If you set [1200dpi] for <Resolution>, it may reduce the thickness of fonts� For detailed procedure, see "Reducing the
thickness of outline fonts�" (p� 62)

How to Fix Misalignment of Images

NOTE

If the following troubles often occur, the machine may have
alignment problems� Follow the procedures described in this
section to solve such problems�

•

The register marks on one side of a printed sheet do not
match those on the other side�

•

The thumb indexes on the printed pages are not aligned�

•

The image is not printed within the register marks�

•

You may not be able to correct misalignment that is less
than 1�0 mm (1/25")�

•

The machine decides the printing start position based on

Step 1 Eliminating the Basic Causes of Misalignment

Find the answers to your questions about how to solve your problems�

Q� Is the machine or paper located in a high humidity environment?

A� Paper tends to expand when it absorbs moisture from a highly

humid environment� If this happens, the images may be printed in the
wrong position� For example, the image may be printed in the lower left
corner, rather than in the center as expected� Or, images printed on the
front and back of the paper may be misaligned�

Solution

•

Keep the machine and paper in a room with a steady temperature and
humidity� If the temperature and humidity are unstable, it may cause the paper
to expand or shrink, resulting in misalignment of printed images�

•

For the appropriate temperature and humidity, see the
Installation and Operating Environment Guidelines or the Specialty Media Handling Guide�

•

Before you load paper, place the package of paper near the machine so it can fully acclimatize to the temperature
and humidity�

•

Unwrap the paper immediately before you load the paper into the machine�

Image is printed near the
edge of the paper because
the paper is larger than the
set paper size.

Q� Is the paper cut correctly?

A� If the paper is not uniform in size and

shape, the margins around the image may be
different on each page� If the paper is not cut
square, the images may be skewed when they
are printed�

Solution

•

Use a different batch of paper that has been cut
correctly�

•

If you cut the paper yourself, measure it and confirm
it is the correct size�

Image is printed near the
edge of the paper because
the paper size was not set in
advance.

Printed image is skewed
because the edges of the
paper are not square.

How to Fix Misalignment of Images

Q� Did you load paper in the correct position?

A� If you place the paper guide in the wrong position or do not align the edges of the paper before you

load it, the printed images may be misaligned on every page�

Paper Guide

Position in which image is printed is
misaligned because the paper guide is in the
wrong position.

Solution

•

Align the edges of the paper and load it again�

•

Make sure that the paper guide is placed in the correct position�

Q� Did you register the paper type correctly?

A� If you load a different brand of paper, different from the

one you have used before, you need to change the settings
for the paper in the machine� If you start printing without
changing the settings, the machine applies the previous
settings to the new paper type, which causes misalignment of
the images on every page�

Solution

Press → [Preferences] → [Paper Settings] → [Paper Settings] →
select the brand of paper that you have loaded�

"Settings/Registration" > "Registering the Paper Size and Type for a Paper Source" in the User's Guide

imagePRESS C850/C750/C650/C65

77

Q� Have the machine got warmed up enough to obtain proper printing results?

A� If you start printing before the machine gets warmed up enough, such as just after turned ON, the

printed images may be misaligned�

Solution

Before you start a print job, warm up the machine by printing 10 to 30 copies of a test page�

Step 2

If Using the Scanner

▀

If the images on the front and back sides are misaligned with each other and you want to adjust easily, you can adjust
the alignment of the images by scanning the test pages with the guide sheet�

Find the answers to your questions about how to solve your problems�

Q� Is the machine or paper located in a high or low humidity environment?

A� The humidity may cause the paper to expand or shrink� If you store the paper in an extremely high or

low humidity environment, the paper may curl before printing�

Solution

•

Keep the machine and paper in a room with steady temperature and humidity� If the temperature and humidity are
unstable, it may cause the paper to expand or shrink, resulting in curled paper�

•

For the appropriate temperature and humidity, see the Installation and Operating Environment Guidelines or the
Specialty Media Handling Guide�

•

Before you load paper, place the package of paper near the machine so it can fully acclimatize to the temperature
and humidity�

•

Unwrap the paper immediately before you load it into the machine�

Q� Are the edges of the image extremely dark?

A� If the edges of the image are extremely dark, the paper may tend

to curl during printing�

Solution

•

Use heavier paper�

•

Decrease the density in the very dark areas to reduce the difference in the
density between the dark and light areas�

condition of the printouts�

•

Repeat steps 1 to 4 to adjust the curl correction level until the paper does not curl when it is output�

The regular procedure is to set the level of curl correction in advance to suit the characteristics of each type of paper�
This is because the curl in the paper depends on the paper's materials and basis weight� However, if significant
changes in the environment, such as temperature and humidity, occur for some reason, and the changes temporarily
affect the condition of the paper, such as moisture content, the curl may not be corrected to your satisfaction� If this
happens, see the following and adjust the level of the curl correction for the paper source in which you have loaded
the paper for which you want to calibrate the machine�

How to Fix a Curl That Is Perpendicular to the Direction of Paper Feed

Printouts may not curl if you print on the back side of the paper� However, be careful of the paper's finish,
because the finish of the front and back sides of the paper may differ, depending on the type of paper� If
