Manual Calibrations

When you run the calibrations from this menu, you evaluate the calibration test patterns visually and enter the calibration values via the control panel. In most cases, AutoSet is more accurate and should be used instead (see “AutoSet” on page 4-2).

Note

Manually performing the component calibrations of

 

AutoSet is time-consuming and can be error-prone,

 

but is necessary when the head height is 0.070

 

inches (1.78 mm) or greater, or when calibrating

 

transparent media. (There is no automatic media

 

feed calibration, so you must always perform it

 

manually.)

 

 

If you decide to manually calibrate the printer, first clean the printhead jets as described in “Cleaning Ink Jets” on page 5-3.

The Manual Calibration menu consists of these options:

◆Media Feed (page 4-4) — enables you to calibrate the printer’s media advance accuracy by printing and visually inspecting your choice of test patterns.

◆Manual BiDi Registration (page 4-7) — prints bidirectional registration patterns and allows you to report which pattern is the most precise.

◆Manual Head Registration (page 4-10)— precisely aligns the printheads relative to each other, for accurate colors and precise registration of images.

◆Manual Jet Mapping (page 4-13)— enables you to detect and report nonfiring or misfiring ink jet nozzles, which enables the printer to “fill in” for them.

◆Jet Status Lines — prints a quick test pattern that shows which jets are out.

◆Default Registration Data — sets all registration data to zero.

After calibration and jet mapping, perform a linearization, or color calibration (as supported by your print server or RIP). For further information, see “Linearization” on page 4-23.
