When Print Quality Is Not Satisfactory
Uneven density (In the case of discharge defects)
[Cause/Technical reason]
If you print with discharge defects such as nozzle clogging or bending, it may appear as
uneven density.
[Solution]
Print a nozzle check pattern to check if there are discharge defects, and if there are
discharge defects, clean the print head.
For details on how to print the nozzle check pattern, see the section "Test Printing" in the
manual "Operating Instructions".
For details on how to clean the print head nozzles, see the section "Cleaning Print Head
Nozzles" in the manual "Operating Instructions".
If discharge defects such as nozzle missing or bending occur frequently, see the section
"Nozzle missing" in this manual.
Uneven density (In cases where media transport is not appropriate)
Uneven density
[Cause/Technical reason]
In order to use this device to print properly, load and feed the media correctly. The
device with the stagger head configuration may experience unacceptable image quality
due to improper media feeding such as skewing.
You can find the factor for uneven density with printed cutter marks. (It does not have to
be a cutter mark, small character or thin line is enough to find the factor.)

10
[Adding registration marks]
Using the ColorGATE RIP, you can add registration marks to the job.
The way to add registration marks may vary depending on the version.
Right click on the job Open the "Settings" window Open the "Job" tab Click
on the cut marks icon Select "Cut Marks".
Using ONYX RIP, you can add registration marks to the job.
The way to add registration marks may vary depending on the version.
Right click on the job Open the "Job Properties" Open the "Marks" tab Check
the "Edge Marks"
[Details / Solution]
The solution varies depending on the problem. See the corresponding item.
▪a≠b
If the registration marks are not on the same level on the right and left positions, the
media is skewed.
page 11 "STEP1-1 If there is skewing"

11
▪a ≈ b≠0
If the registration marks are misaligned in a media feed direction, the media feed
quantity is not correct.
page 12 "STEP1-2 If the media feed quantity is not correct"
▪a ≈ b ≈ 0
It is necessary to further adjust the media feed quantity.
page 12 "STEP2Adjust the actual image by Media Feed Correction"
STEP1-1 If there is skewing
1. The media has not been loaded correctly.
Load the media correctly. See the video, which describes how to load the media, or see
the section "Setting Media" in the manual "Operating Instructions".
How to load the media:
http://support.ricoh.com/services/device/video/M0DY/mediaset/en/index.html
2. The media may be being printed in a rewound state.
If you print on the media rewound area, the machine cannot feed the media correctly.
Use only one way.

12
You can reduce waste media without rewinding by using the "Prevent Drying After
Printing" function on page 47.
3. The media edge may have touched the floor.
If the media edge comes into contact with the floor and the media is pulled to one side,
a media skew occurs. Use the roll-up unit to prevent the media edge from touching the
floor.
STEP1-2 If the media feed quantity is not correct
1. You have not adjusted feed quantity and drop position.
Perform the feed quantity adjustment when change the media, because optimal feed
quantity differs for each media.
See the section "Adjusting the Media Feed Quantity" in the manual "Operating
Instructions".
2. The media feed was adjusted in the part where the media has been fed and
moved back or the media is deformed due to heating.
Parts of media moved back at once has damage due to the heater temperatures and
registration roller.
If you adjust the media feed quantity in the damaged part, a problem such as uneven
density, white lines, or black lines may occur on the media that is undamaged because
the optimal feed quantity may differ between the damaged and undamaged parts.
If this happens, adjust the media feed quantity in the unrewound part.
STEP2 Adjust the actual image by Media Feed Correction
If STEP 1 does not solve the uneven density, try the STEP2 solutions.
STEP2 has three options.
1. Adjust the image with the Media Feed Correction.
2. Print by upper print mode.(for example.16pass is upper print mode of 12 pass.)
3. Change to compatible media. Please contact your retailer or service representative for
compatible media information.
・Media Feed Correction
The uneven density can be improved by using "Media Feed Correction".
You can select the level of media feed correction from level 0 to level 3.
Typically, it is recommended to set Level 0.
If you can see any uneven density, change the setting to level 1.
Media Feed Correction Level0
Media Feed Correction Level1～

13
If this does not solve the problem, change the setting to a higher level.
If media feed correction is too strong, white bands may occur.
If the ink set is 4C or 6C, it is recommended to set Level 2 in 12pass mode (600 x 900dpi).

For ink sets 4C and 6C, increasing the media feed correction level will slow down the print
speed. When the ink set is 4CW, increasing the media feed correction level does not change
the print speed.

STEP3 Adjustment when the feed amount shifts as the job progresses
Depending on the progress of the job, the feed amount may shift, causing uneven density or
changing the condition of unevenness. In this case, if the media feed adjustment can be
performed, perform the media feed adjustment described in No.1 of STEP 1-2. If the media
feed adjustment cannot be performed, such as during printing, etc., adjust the media feed
adjustment (Micro Setting).
[Image Adjustment by Micro Setting]
Media feed adjustment (Micro Setting) can be adjusted from the main unit control panel by
the following method.
1. If you are not printing, press the [Standard Procedure] key.
If printing is in progress, press [PrintingAdjustment] on the operation panel.
2. If you are not printing, press [Media Feed Correction].
If you are printing, press [Media Feed FineAdjustment] and go to No.4.
3. Press [Micro Setting].
4. If the media feed quantity is misaligned and Uneven density occurs, black lines or white
lines will appear in the output image depending on the amount of misalignment.
When black lines appear, the feed amount are too small, so enter the value on the
"+ (plus)" side.
When white lines appear, the feed amount are too large, so enter the value on the
"-(minus)" side.
Enter the value in increments of ± 4 as a guide.
5. Press [Close] to close the setting screen and print.

15
Uneven density at the media edge (Not in the center)
[Problem]
Uneven density occurs at the edge of media.
[Cause/Technical reason]
When you use eccentric media, uneven density occurs because media feed quantity is
not even at the center or edge of the media.
In many cases, since the tension at the media edge becomes loose, the feed amount is
not stable and uneven density occurs.
[Solution]
If the roll media is being stored in an unsuitable way, it may become deformed. Support
the roll core so that the media does not touch the floor.

16
Uneven density (Media is stuck on the platen)
[Problem]
[Cause/Technical reason]
The media may be stuck to the platen. If media that is sticky on the back is being used,
the media may stick to the platen or roll media, resulting in a paper feed error.Also, the
platen may be stained, resulting in paper feed error.
[Solution]
▪Because of the heater temperature, the media may become stickier. Reduce the
heater temperature.
If ink is adhesive on the platen, clean it with a paper towel soaked in alcohol such
as Solmix.
(Refer to the section "Cleaning the platen" in the manual "Requests for Daily Care
and Maintenance".)
▪If the media sticks on the roll media:
Please pull out the media once and wind it around the roll core again. The media
stickiness will become weaker.
▪Good

Wind again
Uneven density (Rapid temperature changes)
[Problem]
[Cause/Technical reason]
If the printing is not performed for a certain period of time, the printer goes into "Cooling
Mode" and the heater temperature drops.
If you start printing from "Cooling Mode", the media undergoes rapid thermal changes
due to the heater, so abnormal images such as uneven density may occur depending
on the media and environment.
[Solution]
If you are concerned about the image quality, set a small "Cooling Ratio" of the "Cooling
Mode Setting".

18
For details on how to set the "Cooling Mode", see the section "Configuring Cooling
Mode" in the manual "Operating Instructions".
Or before start printing, feed the media until deformed area disappears after the heaters
reach the temperature set in icc profile.
Black Lines (Case of the media feed quantity is inappropriate)
[Problem]
Black lines appear at intervals of media feed pitch.
①Media feeding pitch
There are three reasons for the Black Lines (Case of the media feed quantity is
inappropriate.
1. Media feed quantity is not adjusted appropriately
2. Vacuum level is not fitting
3. Black lines appears with job printing proceeding.Also, the level of black lines will change
with job printing proceeding
1. Media feed quantity is not adjusted appropriately
[Cause/Technical reason]
The media feed quantity is not correct.
The feed quantity is not adjusted properly or Media FeedAdjustment (Micro Setting) is
too short.
[Solution]
Adjust the feed quantity correctly, because optimal feed quantity differs for each media.
See the section "Adjusting the Media Feed Quantity" in the manual "Operating
Instructions".
In the case of adjusting the media feed quantity with the part where the media has been
fed and moved back or the deformed due to heating, adjusted value may be incorrect.
The rewound media and heated media are damaged by the registration roller and
heater temperature. If you adjust feed quantity in the damaged part, black lines may
occur on undamaged parts, because the optimal feed quantity may differ between
damaged parts and undamaged parts.

19
For details on how to check if the Micro setting is adjusted appropriately, refer to [Image
Adjustment by Micro-Setting] in [Uneven density (Major case)] [STEP1-2 If the media
feed quantity is not correct].
"Reduce sticking" function can prevent the media from sticking on the platen.
Turn this function [On] when you use the media that easily sticks on the media feeding
surface, such as synthetic paper or a banner. When this function is set to [ON], the
rewinding operation will be performed before printing. If you use the media that does not
stick on the media feeding surface, turn this [OFF] to stabilize print quality. If you change
this setting to [OFF], perform the [Media Feed adjustment] again.
For more details, refer to the section of "Reduce Sticking" in the manual "Operating
Instructions".
2. Vacuum level is not fitting
[Cause/Technical reason]
A black line may occur if you raise the vacuum level after adjusting the media feed
quantity.
This is because the media feed quantity differs as the load of the media increases.
The following images describe the trend of the vacuum level and black lines.
As the vacuum level get stronger, black lines become noticeable.
* +9 is the strongest setting.
* Feed adjustment is performed at vacuum setting +2.
[Solution]
Basically, default setting is the best to get the high quality image.
If the media jams or floats, raise the vacuum level and perform feed adjustment after
changing the vacuum level setting.
3. Black lines appears with job printing proceeding. Also, the level of black lines will
change with job printing proceeding
Black lines occur, and the level changes as the job progresses.

20
[Cause/Technical reason]
Media thickness are not correct.
Feed quantity is corrected according to the media thickness setting while printing.
If this setting is not correct, the correction function does not work.
[Solution]
Please set the media settings correctly referring to the section "Setting Media" in the
manual "Operating Instructions".
Black Lines (Heater temperature may be too low)
[Problem]
Black lines appear at intervals of the media feed pitch.
①Media feeding pitch
[Cause/Technical reason]
The heater temperature is not high enough to dry the dropped ink.
In the case of using high speed mode (6pass or 8pass), black lines occur at only dark
image position due to too much ink.
[Solution]
Use the appropriate profile, raise the heater temperature or increase the drying time.
Change the pre and print heater settings to about 10 °C higher.
Use UNI direction to increase the drying time. It can be select on RIP software.
When using ColorGATE RIP, right click on the job select "Settings" select
"Advanced" under the "Color" tab select "Settings" select the "Print Mode" tab
and untick "Bidirectional"
When using ONYX RIP, open print setting select Unidirectional on printing direction.
