Chapter 5 What to Do If

103

5-2 Attractive Printing/Cutting Is Impossible

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 35 "Printing Test and Cleaning"

☞ p 45 "When Head Cleaning Is Not Effective"

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 cor-

rection on the printer.

☞

p 67 "Performing Feed Correction to Alleviate Horizontal Bands and the like"

Have you carried out bidirectional correction?

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 64 "Correcting for Misalignment in Bidirectional Printing"

Are the print heater and dryer at a suitable temperature?

If ink forms lumps or smudges, raise the temperature. Note,

however, that a temperature that is too high may degrade

the media or cause it to wrinkle.

☞

p 32 "Print Heater and Dryer Settings"

Is the temperature of the room too low?

The print heater and dryer may not warm up sufficiently

when the temperature is 20 ˚C (68 ˚F) or lower. Also even

when they reach their preset temperatures, adequate effec-

tiveness may not be apparent if the media is thoroughly

chilled. Before printing, allow the media to come to room

temperature.

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 affected.

☞

p 106 "Media Wrinkles or Shrinks, or Feed Is Unstable"

Colors Are Unstable or Uneven

Did you shake the ink cartridges gently before installing them?

If you're using a model that uses ECO-SOL INK, gently shake

the cartridge before you install a new cartridge.

Is the media wrinkled?

If the media is wrinkled and comes loose from the platen,

colors may be uneven or printing quality may suffer.

☞

p 106 "Media Wrinkles or Shrinks, or Feed Is Unstable"

Was printing paused partway through?

When printing is paused, the coloring at the seam may be

altered when printing resumes. Avoid pausing printing. With

the factory-default settings, printing pauses when an ink

cartridge runs empty. Before you perform lengthy printing,

check the amount of ink remaining in the ink cartridges.

Printing may also pause when data is not sent from the com-

puter quickly enough. We recommend not performing any

other tasks with the computer while printing is in progress.

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, ensure

that the print heads are not exposed to wind or blown air.

These factors may lead to missing dots or reduced printing

quality.

The Media Becomes Soiled When Printed

Are the print heads dirty?

The following may cause ink to drip on the media during

printing.

• Buildup of fibrous dust (lint) around the heads

• Ink transferred to the heads due to rubbing against the

media.

If this happens, clean the heads using the cleaning kit. We

recommend carrying out periodic head cleaning.

☞

p 46 "Cleaning the Heads Using the Cleaning Kit"

Are the pinch rollers dirty?

Periodically clean the pinch rollers.

Cutting Is Misaligned or Skewed

Is the media loaded and set up correctly?

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