When Print Quality Is Not Satisfactory
28
Characters are Faint (Case4)
[Problem]
Image misalignment even if drop position adjustment and feed quantity adjustment was a
success.
[Cause/Technical reason]
There are two reasons that cause possibly.
1. Using high temperature for pre-heater or print heater enough to deform media such as
waving or curls.
2. Using uneven media such as nubby texture, with holes media, or with the pattern.
If you perform auto drop position adjustment in deforming part or uneven media,
this function does not work properly. Image misalignment occurs due to incorrect
adjustment values.
[Solution]
Please adjust the drop position in the un-deformed part of media.
We have two items for preventing deformation the media.
1. Changing the pre-heater and print heater to a lower setting.
When it is too low, bleeding may appear. Therefore, you should change setting little by a
little while watching medias behavior.
See the section “Heater temperature & ink limit”.
2. Changing vacuum level to a stronger setting.
Please adjust feed quantity after changing vacuum level.
When the vacuum level is too strong, black lines may appear.
If you use the uneven media, perform the manual drop position adjustment.
See the section “Adjusting the Media Feed Quantity" in Operating Instructions.
We recommend using adjustment value register and retrieve function.
It is possible to omit the adjustment of media feed quantity when using the same media
again.
