Chapter 6 What to Do If...
6-1 What to Do If...
Clean, attractive printing is impossible
If drop-out occurs with printed images.
Clean the printing heads (see "4-1 Cleaning the Printing Heads").
The printed images are not clean.
Clean the platen and pinch rollers. (see "4-4 Other Cleaning Tasks")
The printing heads scrape the surface of the media.
Is the loaded media very thick?
If media feed is not smooth because the media catches on the head, then adjust the height of the printing heads (see "2-
3 Loading Media -- When Loading Thick Media (Only When printing)").
When the height of the printing head has been adjusted, it is necessary to perform bidirectional correction. For more
information about bidirectional correction, see "3-5 Making Corrections for Printing -- Bidirectional Correction".
If you are using media that becomes uneven when printed, then perform unidirectional printing. With unidirectional
printing, unevenness is less conspicuous than bidirectional printing.
Also, if the printing heads scrape the media even when the heads are raised, then do not use that media.
Doing so may not only cause paper jams, but may soil the media (the printing surface) and impair printing accuracy.
The results of printing are coarse.
Has feed correction been performed?
Correcting the amount of feed improves the dot-positioning accuracy in the feed direction, which can help enhance
image quality.
If the type of media was changed, refer to "3-5 Making Corrections for Printing -- Feed Correction" and perform correc-
tion for feed.
Has bidirectional correction been performed?
If misalignment like in the example occurs when perform-
ing bidirectional printing, then carry out correction at the
[BIDIRECTION] menu (see "3-5 Making Corrections for
Printing -- Bidirectional Correction").
Be sure to make this setting when you have replaced the
media with a different type, or if you have adjusted the
head height and printing is misaligned.
The printing length is not accurate
Is the loaded media very thick?
To correct the amount of feed, refer to "3-5 Making Corrections for Printing -- Feed Correction" and make the correction
to match the media you're using.
[EXAMPLE]
OK: Correct
Not OK: Single lines not produced
