●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.
