Points to check Corrective action
Does the media have ripples/surface
irregularities or lift up?
If you are using roll media, use a smooth section of the media for
initial feeding. You can also improve this problem by attaching the
NITOFLON
®
tape provided on the platen.
Be careful not to cover the vacuum holes.
For more information, refer to the description on transporting media
on the platen. https://mimaki.com/download/inkjet.html

occur.
(Carriage scan direction)
1. Remove any paper scraps or other debris adhering to areas over which
the head passes (e.g., media holders). "Media Holder
Cleaning"(P. 146) "Platen Cleaning"(P. 147)
2. Perform the procedure described in "Head Cleaning"(P. 73).
3. Perform the procedure described in "Feed Correction"(P. 75).
4. Perform the procedure described in "Cap Rubber Cleaning"(P. 138).
5. Perform the procedure described in "Carriage Underside
Cleaning"(P. 139).
Text is double- or triple-printed in the
media feed direction.
1. Perform the procedure described in "Feed Correction"(P. 75).
Offsetting occurs during bidirectional
printing.
1. Perform the procedure described in "Correcting the Drop

Are the print heads too high? Adjust the print head height. "Adjusting Print Head
Height"(P. 49)If the print heads cannot be lowered, increase the
refresh level during printing ( P. 117) or perform regular test
printing to check for nozzle clogging.
Are there any ink colors that aren't
used much?
Discharge from infrequently used nozzles tends not to be consistent.
Although increasing the refresh level during printing (Maintenance
Menu) will enable more frequent nozzle use, note that this will also
increase ink consumption.
Are you using media easily affected
by static electricity?
Increase the refresh level during printing ( P. 117) or perform
regular test printing to check for nozzle clogging.
