● Printhead X Calibration — the manual version of Auto Head X Calibration.
● Manual Jet Mapping — the manual version of AutoJet.
● Default Registration Data — sets all registration data to zero.
After calibration and jet mapping, perform a linearization or color calibration (as supported by the
RIP). See
Linearization on page 53 .
NOTE: The manual BiDi and X head calibrations are time-consuming and can be error-prone, but is
necessary when calibrating transparent media or other media that the printer’s digital image sensor
cannot calibrate.
Media Feed Calibration
This calibration allows you to calibrate the accuracy of the media advance. Inaccurate media advance
can result in blank spaces between print swaths (too much advance) or overlapping swaths (too little
advance).
1. On the Manual Calibrations menu, press Media Feed.
2. Press the Yes button to proceed. The control panel displays the following options:
990 mm (39 in) calibration — sheet fed only, uses the printer's onboard image sensor for precise
adjustments. If the media feed needs larger adjustments, use the ruler-measured calibrations
first. Use for maximum accuracy.
510 mm (20 in) calibration — sheet fed only, uses the printer's onboard image sensor for precise
adjustments. If the media feed needs larger adjustments, use the ruler-measured calibrations
first. Use to conserve media.
900 mm (34 in) calibration — prints a 900 mm (34 in) test pattern so you can verify its length
with an accurate metal ruler. Cut the pattern from the media web, then measure and adjust the
media advance as needed until the pattern is exactly 900 mm (34 in) long.
250 mm (10 in) calibration — prints a 250 mm (10 in) test pattern so you can verify its length
with an accurate metal ruler. This is not as precise as the 900 mm (34 in) calibration, but it uses
less media. Measure and adjust the media advance as needed until the pattern is exactly 250
mm (10 in) long.
The image-sensor based calibration (sheet-fed media only) prints a reference pattern, ejects the
media, and prompts you to rotate and reload the media so the pattern can be measured. To
account for the slight variability in the media feed mechanism, repeat these calibrations three to
five times to obtain the best calibration. The software allows you to position the patterns
anywhere on the sheet so you can print multiple iterations on the same sheet.
Input MFN — enter the Media Feed Number that was displayed after a previous media feed
calibration, to return to that setting without performing the calibration again.
