Updates |3
English
Your printer includes updated firmware, new troubleshooting recommendations, and a kit containing a
new alignment tool and adjustment guides.
This booklet describes the updates and tells you how to perform parallel adjustment using the new parts.
Updates
The new firmware and troubleshooting procedures include the following:
•The Feed Speed option for custom media is set to Auto by default. If you see strips of uneven color,
horizontal lines, or banding on printouts, try lowering the feed speed to Lv1.
•The message displayed for ink and chip unit replacement is: Check Ink Levels.
Note that the use of a face mask is recommended when refilling ink or replacing the waste ink bottle.
•If media printed at high density is creased, set the Take-up Tension to Manual, and choose Lv1 or
Lv2.
If media skew is detected, try the following recommendations:
•Use the parallel adjustment procedure described in this booklet.
•Set the auto take-up unit to roll the media with the printed side in.
•Use media at least 36 inches (91.4 cm) wide.
•For thick media, set the software RIP to 3 passes or higher.
Parallel Adjustment
The parallel adjustment procedure ensures that media is fed straight into the printer and onto the auto
take-up reel. Use this procedure if you have problems with media feeding or take-up, or if the printer has
been moved.

4|Adjusting the Media Feeding Unit
You can use the adjustment paper included with the printer, as described in the User’s Guide or the new
adjustment guides and alignment tool (shown below), as described in this booklet.
Before you begin the parallel adjustment procedure, make sure the printer is leveled and on a level surface.
Carefully unroll the adjustment guides.
Adjusting the Media Feeding Unit
Two people are required for parallel adjustment, one in front of the printer, and one in back. Make sure
the printer is off before you begin.
1. Open the front cover and push back the media loading lever.
