Ink drops
o
Is media being handled appropriately?
If the following points are not observed when
handling media, small amounts of dust and lint may
stick to the media surface and cause ink drops in the
print results.
❏ Do not place exposed media directly on the floor.
Media should be rewound and inserted in its
original packaging for storage.
❏ Do not carry media with the media surface
pressed against clothing.
Handle media in its individual packaging until
just before loading the media in the printer.
Horizontal stripes or tint unevenness
(banding)
Multiple causes are possible.
Perform the following sequence until the print results
have improved.
If the following problems remain unsolved, this
symptom will not be able to be resolved by taking any
actions. Before taking any actions, check that such
problems have been resolved.
❏ Nozzles are clogged.
U “Checking for clogged nozzles” on page 128
❏ Media settings are not configured correctly.
U “Saving media settings” on page 83
A
Check the attachment of the media holding
plates
If a media holding plate is not installed correctly,
media feeding may be disturbed. See the
following reference and reattach the media
holding plates.
U “Loading and Exchanging Media” on
page 33
If installing the media holding plate correctly still
does not resolve the problem, perform the
following measure.
B
Resolving ink sedimentation
Ink sedimentation (components settling to the
bottom of the liquid) may occur inside the
printer. Perform Ink Refresh.
U “Ink Refresh” on page 132
If this error recurs after Ink Refresh was
performed, take the following action.
C
Feed Adjustment
Feed adjustment may be required independently
depending on the media used. If the roll width is
different, independent adjustment is required
even with the same media. In Media Adjust,
select Feed Adjustment - Manual - 500mm
Pattern to make adjustment.
U “Changing settings during printing” on
page 89
If feed adjustment does not resolve the problem,
perform the following measure.
D
Resolving ink drying time differences
During bidirectional printing, print head
movement may cause an ink drying time
difference. Firstly, perform unidirectional
printing from RIP. If this improves the print
results, change the Heater Temperature or
Drying Time Per Pass, and adjust so that stripes
and unevenness are improved during
bidirectional printing.
