Adjustments for Better Print Quality
Note
• If advanced adjustment does not improve printing results, or if you are using special paper, try manual
adjustment.
For instructions on manual adjustment, see "Manual Straightening of Lines and Colors (Manual Head
Adj)."
• Use Standard Adj. if you have switched to another type of paper or if you want the boundaries between
colors to appear as attractive as possible.
• Use Advanced Adj. to fine-tune the space between nozzles or colors if you have switched the printhead
or if you want printed documents to appear as vivid as possible. We recommend using Advanced Adj.
for printing at a higher level of image quality.
• Always make sure the loaded paper matches the type of paper specified on the printer. Adjustment can-
not be completed correctly unless the loaded paper matches the settings.
• We recommend using the type of paper you use most often for adjustment.
• This function is not available with CAD Tracing Paper, CAD Translucent Matte Film, or CAD Clear
Film. If adjustment is not possible as expected using highly transparent film or similar media, try another
type of paper, or try adjust the Printhead alignment manually. (See "Manual Straightening of Lines and
Colors (Manual Head Adj).")
