Enhancing Printing Quality
With some types of paper and under some conditions, adjusting the printer as follows with the paper to be used can enhance printing quality when printing fine lines/text or photos.
Two adjustment options are available: standard adjustment (with the Printhead height set to Automatic ) and supplemental adjustment (used if standard adjustment is not effective).
Important
•  Ideal temperature and humidity during adjustment and for printing in general when the Printhead height is set to Automatic are 20–30ºC and 30–60%. Under other environmental conditions, adjustment may not enhance printing quality.
Note
•  Paper used for adjustment must conform to the following specifications.
Type: Glossy or semi-glossy photo paper, or proofing paper (in either case, roll paper only)
Thickness/weight: 300 μm or less, or 300 g/m² or less
Width: 25.4 cm (10 in.) or more

  Standard Adjustment
Perform standard adjustment with the Printhead height set to Automatic.

A test pattern is printed for adjustment. This process will take about 11 minutes.
Note
•  If standard adjustment does not enhance printing quality, next try supplemental adjustment, which may be helpful.

  Supplemental Adjustment
Perform supplemental adjustment with the Printhead height set to Super Low.
Important
•  Printing with Head Height set to Super Low may enhance printing quality, but it may also cause paper to rub against or become caught on the Printhead, which may cause paper jams or soiling on printed documents.
  1. Set Head Height to Super Low.  (See "Troubleshooting Paper Abrasion and Blurry Images (Head Height) (7.2.4).")
    Note
    •  If Super Low is not available, select Lowest.
  2. In Head Posi. Adj., select Auto(Expansion).
    Note
    •  If paper rubs against the Printhead or becomes jammed during Printhead height adjustment, try selecting a higher level in Head Height and performing Auto(Expansion) again.
  3. Return Head Height to Automatic.
    Important
    •  If Head Height is not returned to Automatic, the printer will print with the Printhead height set to Super Low.  (See "Troubleshooting Paper Abrasion and Blurry Images (Head Height) (7.2.4).")
