Roland TrueVIS VG2-540 - Printed Results Are Coarse or Contain Horizontal Stripes; Do the Print Heads Cause Dot Drop-Out; Is the Print Head Height Appropriate; Have You Carried out Feed Correction

Do the print heads cause dot drop-out?
Carry out a prinng test and make sure no dot drop-out or dot displacement occurs. If dot drop-out or dot dis-
placement is present, perform head cleaning.

Is the print head height appropriate?
Prinng when the [HEAD HEIGHT] menu item is set to "HIGH" or to "MIDDLE" is coarser than when set to "LOW".
Keep this set to "LOW" except when changing it is necessary, such as when you are using thick media.

Have you carried out feed correcon?
Large misalignment in the amount of feed of the media may result in prinng that seems coarse or contains hori-
zontal stripes. Either make the seng in the soware RIP to match the type of media you are using, or make the
seng for correcon on the printer.

Have you carried out correcon of the ink landing posion (MEDIA GAP ADJ.)?
The opmal adjustment value varies depending on the thickness of the media. Set an adjustment value that is
suitable for the media. When further correcon is required, such as when adjustment made using [SIMPLE SET-
TING] does not enhance prinng, use [DETAIL SETTING] to make the correcon.

Is the printer installed in a level and stable locaon?
Never install the machine in a locaon where it is lted or where it may wobble or experience vibraon. Also make
sure that the print heads are not exposed to moving air. These factors may lead to dot drop-out or reduced print-
ing quality.
Is the media heang system at a suitable temperature?
If the 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.
