Enhancing Printing Quality (iPF9400) (iPF9400S)



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).
  • Ideal temperature and humidity during adjustment and for printing in general when the Printhead height is set to Automatic are 2030 deg C and 3060%. Under other environmental conditions, adjustment may not enhance printing quality.


Standard Adjustment

Perform standard adjustment with the Printhead height set to Automatic.



1. Load paper in the printer.



2. On the Tab Selection screen of the Control Panel, press or to select the Settings/Adj. tab ().
  • If the Tab Selection screen is not displayed, press the Menu button.



3. Press the OK button.
The Set./Adj. Menu is displayed.



4. Press or to select Adjust Printer, and then press the OK button.



5. Press or to select Head Posi. Adj., and then press the OK button.



6. Press or to select Standard, and then press the OK button.
A test pattern is printed for adjustment. This process will take about 13 minutes.
  • 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.
  • 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.
  • We recommend that additional adjustment be executed using paper matching the following criteria.
Type: Glossy or semi-glossy photo paper, or proofing paper (in either case, roll paper only)
Thickness/weight: 300 m or less, or 300 grams per square metre or less
Width: 420.0 mm (16.54 in.) or more



  • If Super Low is not available, select Lowest.



2. Execute Standard in Head Posi. Adj..
  • If paper rubs against the Printhead or becomes jammed during Printhead height adjustment, try selecting a higher level in Head Height and performing Standard again.
