Description
The  bidirectional-printing  mode  (in  which  the  heads  perform  printing  during  both  their  outbound  pass  and  return  pass) 
offers the advantage of being able to shorten printing times, but subtle misalignment occurs during the outbound and re -
turn passes. The procedure to correct this and eliminate misalignment is bidirectional correction. This misalignment varies 
according to the head height and the thickness of the media, so we recommend performing correction to match the media 
you're using.
This settings also serves to correct for misalignment of the printing and cutting positions. In such cases, check or adjust this 
setting.

Description
The  movement  distance  of  media  experiences  subtle  changes  due  to  the  thickness  of  the  media  . When  the  movement 
distance becomes discrepant, horizontal stripes are more likely to occur during printing. We recommend performing cor -
rection to match the media you're using and the media heating system. Also, perform the actual printing in an operating 
environment identical to that used for the test pattern.

Description
The movement distance for the media changes subtly depending on the media's thickness. This means that the length of a 
line when cut may differ from the length setting in the data. You enter a correction value when you want to align the lengths 
of cut lines precisely. 
When performing printing followed immediately by cutting, be sure to set this to "0.00."

[OFFSET ]: This makes the blade-offset setting for the blade. Enter the listed offset value for the blade. (The offset value for 
the included blade is 0.25 mm.) 
[UP-SPEED]: This sets the blade's up speed during cutting (the speed at which the blade travels when it moves to the next 
cutting line after cutting one cutting line). If the media comes loose during no-load feed and the blade damages the surface 
of the media, reduce the speed.

Evaluating the Results of a Cutting Test 
Check the shape of the test pattern.
The cut shape is distorted.
Reduce the cutting speed.
Peel off circle 1.Rectangle 2 also peels off. 
Increase the blade force. 
Some uncut areas remain. 
Reduce the cutting speed. 
Peel off rectangle 2. 
The blade should leave faint traces on the backing paper. 
The blade trace is indistinct.
Increase the blade force. 
The blade trace is too deep and cuts into the backing paper. 
Reduce the blade force.
Check the shape of rectangle 2.A. The shape is correct.
B. The corners are rounded.
Increase the amount of blade offset. 
C. The corners have "horns."
Reduce the amount of blade offset. 
Adjusting the Cutting-in Amount 
When you want to perform accurate and fine adjustment of the cutting-in amount, such as when cutting media with thin 
carrier paper, you can obtain good results by adjusting the tip of the blade.Turn the cap portion of the blade holder to adjust 
the amount of blade extension. Each indicator tick corresponds to 0.1 millimeters, and adjustment for 0.5 millimeters can be 
made by rotating the cap one full turn.

Rough Estimate for the Amount of Blade Extension
Use the following dimension as a rough estimate for setting the amount of blade extension.
Note that making the amount of blade extension too small may cause the end of the cap for the blade 
holder to touch and damage the printed surface. It's important to be especially careful about this when 
you're using media that has poor ink-adhesion properties.
