Various devices mounted on the machine can be set.
Use this function to clean the machine's fusing unit
when dots or other dirt appear on the printed side of the paper.
When this function is executed, "V" printed paper is output and
the fusing unit is cleaned.
This machine periodically executes automatic cleaning
and normally it is not necessary to execute this mode. Only in case,
however, that black lines appear on the printed paper, execute this
mode.
Adjust black text and the width of black lines.
After using this function to perform adjustment, perform [System
Settings] - [Common Functions] - [Auto Gray Calibration (for Copy)],
[Auto Gray Calibration (for Print)].
Specify to use the dark streak reduction or
not.
The dark streak reduction can be used for Scan Original, Copy,
Image Send, and Scan to local drive functions.
If the dark streak reduction is enabled, select any of the
following options.
Treat Thin Dark Streaks: Use this setting to make thin dark
streaks less apparent. (Low level)
Normal: Use this setting to make dark streaks less apparent.
(Medium level)
Treat Up to Thick Dark Streaks: Use this setting to make thick
dark streaks less apparent. (High level)
Set this option to display a warning message
when dark streaks are detected by the document feeder.
You can easily perform copy quality adjustment
in the default state.
You can change the default setting ([2]) to [1 (Smooth)] or
[3 (Sharp)].
You can adjust the gradation, and density of
copies.
The density is divided into 3 ranges and you can adjust the
level.
Configure settings for black & white copying
when [Auto] is selected for the copy exposure. The exposure can
be adjusted separately for copying using the document glass and
copying using the auto document feeder.
You can make copy images in the default state
sharper or softer.
Specify image quality priority. Set this for
the auto copy exposure and text / printed photo settings.
Perform quick adjustment of print quality.
You can change the default setting ([2]) to [1 (Smooth)] or
[3 (Sharp)].
You can adjust the gradation, and density of
printing.
The density is divided into 3 ranges and you can adjust the
level.
Set the density of printing.
When lines do not print correctly in special
applications such as CAD, you can make lines thicker.
Set the color tone (RGB) for scanning.
Use this setting to obtain a sharp image when
scanning an original.
You can adjust the contrast of scanned images.
Performs automatic grayscale correction.
For copying, adjust with [Auto Gray Calibration (for Copy)].
For printing, adjust with [Auto Gray Calibration (for Print)]. You
can use [Copy Calibration by Screen] and [Printer Calibration by
Screen] to perform even higher precision adjustment of each mode.
The machine prints a test patch, the test patch is scanned,
and the grayscale is automatically corrected.
After the [Execute] key is tapped and a test patch is printed,
a message appears prompting you to begin automatic calibration.
Follow the instructions in the message to perform gray adjustment.
If uneven density occurs in a copy and others,
use this function to smooth the density.
The uneven density is automatically corrected by scanning
a test patch that you print.
After the [Execute] key is tapped and a test patch is printed,
a message appears prompting you to begin automatic calibration.
Follow the instructions in the message to perform density smoothing.
If there are no problems after adjustment, perform "Auto Gray
Calibration (for Copy)" and "Auto Gray Calibration (for Print)".
To return the adjusted values to their factory default state,
tap [Return Density Smoothing Adjustment Value to Defaults]. If
you tapped [Return to the Defaults], perform adjustment of the density
that you want to readjust (medium density in the default mode).
