Vertical ruled lines are misaligned.The printed surface is scuffed or soiled.oIs the print head misaligned? (in bidirectional printing)
With bidirectional printing, the print head prints while moving left and right. If the print head is
misaligned, ruled lines may be misaligned accordingly. If vertical ruled lines are misaligned with
bidirectional printing, perform Head Alignment.
See “Minimizing Print Misalignments (Head Alignment)” on page 189.
oIs the paper too thick or too thin?
Check that the paper specifications are compatible with this printer. For information about the
media types and appropriate settings for printing on paper from other manufacturers or when
using RIP software, see the documentation supplied with the paper, or contact the dealer of the
paper or the manufacturer of the RIP.
oIs the paper creased or folded?
Do not use old paper or paper with folds in it. Always use new paper.
oIs the paper wavy or slack?
Cut sheets become wavy or slack due to changes in temperature or humidity which may result in
the printer being unable to recognize the paper size correctly. Flatten the paper before loading
it in the printer, or use new paper.
oIs the print head scuffing the printed surface?
If the surface of the paper is scuffed, select a Platen Gap option between Wide and Wider in the
Paper menu.
See “Paper menu” on page 171.
oIs the print head scuffing the edge of the paper?
Select Top35mm/Bottom15mm for the Roll Paper Margin option in the Setup menu.
See “Setup menu” on page 175.
oWiden the bottom margin
Depending on the paper usage, storage conditions, and the content of the print data, the
bottom edge may be scuffed when printing. In this situation it is best to create your data with a
wider bottom margin.
oDoes the interior of the printer need cleaning?
The rollers may need cleaning. Clean the rollers by feeding and ejecting paper.
See “Cleaning the inside” on page 201.
