Clean, attractive printing is impossible
If drop-out occurs with printed images.
Clean the printing heads (see "3-3 Cleaning the Printing Heads").
Is the surface of the platen dirty or scratched?
Clean the platen (see “3-7 Cleaning”).
Is the material dirty?
Remove superficial soiling, then load the material.
Is the material damaged?
Clean, attractive printing is not possible if the material is damaged or warped.
Use care to keep materials from being damaged while in storage.
During printing, was the front cover opened (executing an emergency stop) or the [PAUSE] key pressed?
If operation is stopped or paused while printing is in progress, the quality of the image before and after the interruption may differ. It is a
good idea to avoid pausing operation while printing is in progress whenever possible.
Is thick material in use, or does the surface of the material rub against the printing heads?
If material feed is not smooth because the material catches on the head, then adjust the height of the printing heads (see "4-2 Adjusting
the Height of the Printing Head").
When the height of the printing head has been adjusted, it is necessary to perform bidirectional correction (only when the printing
direction for [PRINT QUALITY] has been set to [BI-DIRECTION]). For more information about bidirectional correction, see "2-5
Printing - Making Corrections for Printing - Bidirectional Correction."
If you are using material 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 material even when the heads are raised, then do not use that material.
Doing so may not only cause paper jams, but may soil the material (the printing surface) and impair printing accuracy.
If the type of material was changed, was feed correction 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 material was changed, refer to "2-5 Printing - Making Corrections for Printing - Feed Correction" and perform correction
for feed.
During printing, ink drips from the carriage and soils the material (the
printing surface).
The following may cause ink to drip on the material during printing.
- Dust or fiber-containing grime around the heads may have absorbed ink.
- The heads scraping the material may have caused ink to fail to be discharged, resulting in ink buildup in the heads.
If this happens, refer to "3-3 Cleaning the Printing Heads -- Using the Cleaning Kit to Clean the Printing Heads" and clean the heads.
Also, before you start printing, perform a printing test to make sure there is no dot drop-out.
Printing goes beyond the loaded material
Is [SHEET TYPE] set to [CLEAR]?
When [SHEET TYPE] has been set to [CLEAR], no detection of the material width is performed when material is loaded (printable
width set to maximum).
If transparent material has been loaded, specify a printing area that matches the actual material width (see "2-5 Printing -- Printing at the
Desired Location -- Setting the printing area in the left-right direction (the direction of carriage movement)").
If opaque material has been loaded, set [SHEET TYPE] to [OPAQUE].
Is the reflective tape dirty?
If the reflective tape becomes soiled, the width of the material cannot be detected correctly.
If the tape becomes dirty, wipe gently with a cloth moistened with water or ethyl alcohol.
Has the material been loaded at an angle?
If the loaded material is not straight, it may extend outside the printing area.
Refer to "2-3 Loading the Material" and load the material correctly.
