Printed Results Are Coarse or Contain Horizontal Stripes

Do the print heads show dot drop-out?

Carry out a printing test and make sure no dot drop-

out occurs. If dot drop-out is present, perform head

cleaning.

 P. 42, "Printing Tests and Cleaning"

 P. 72, "When Head Cleaning Is Not Eective"

Is the head height appropriate?

Printing when the [HEAD HEIGHT] menu item is set to

"HIGH" is coarser than when set to "LOW." Keep this set

to "LOW" except when changing it is necessary, such

as when you're using thick media.

 P. 93, "Adjusting Head Height to Match Media Thick-

ness"

Have you carried out feed correction?

Large misalignment in the amount of feed of the

media may result in printing that seems coarse or

contains horizontal stripes. Either make the setting on

the computer to match the type of media you're using,

or make the setting for correction on the printer.

 P. 115, "Performing Feed Correction to Alleviate Horizontal

Bands and the Like"

Have you carried out bidirectional correc-

tion?

When you are performing bidirectional printing, use

the [ADJUST BI-DIR] menu item to carry out correction.

The optimal adjustment value may vary, depending

mainly on the thickness of the media. Set or select an

adjustment value that is suited to the media.

 P. 111, "Correcting for Misalignment in Bidirectional

Printing"

 P. 112, "Correcting for Misalignment in Bidirectional Print-

ing More Precisely"

Is the media heating system at a suitable

temperature?

If the ink forms lumps or smudges, raise the tempera-

ture. Note, however, that a temperature that is too

high may degrade the media or cause it to wrinkle.

 P. 38, "Settings for the Media Heating System"

7-2 Attractive Printing or Cutting Is Impossiblea

Is the temperature of the room too low?

The media heating system may not warm up suf-

ciently when the ambient temperature is less than

20˚C (68˚F). Also, even when the media heating system

reaches its preset temperatures, adequate eective-

ness may not be apparent if the media is thoroughly

chilled. Before printing, allow the media to come to

room temperature.

Is the print mode suitable?

If attractive printing is impossible even when the

media heating system is at a high temperature, try

using a higher-quality print mode.

Depending on the media, smudging may occur when

using a high-quality print mode, and results may also

vary greatly depending on the settings of your RIP

program (such as the color-prole selection). Make

settings suited to the media you're using.

Is the printer installed in a level and stable

location?

Never install the machine in a location where it is tilted

or where it may wobble or experience vibration. Also

make sure that the print heads are not exposed to

moving air. These factors may lead to missing dots or

reduced printing quality.

Is the media loaded and set up correctly?

If the media is not loaded and set up correctly, media

feed may not be smooth, or printing may be adversely

aected.

 P. 151, "Media Wrinkles or Shrinks, or Feed Is Unstable"

Are the settings for the [PRESET] menu item

appropriate?

If the settings selected with the [PRESET] menu item

are not suitable for the type of media, printing may

be adversely aected. Choose settings optimized to

the media you're using.

 P. 127, "Saving Optimized Media Settings As Preset

Values"
