HP Designjet T7100 Printer series - Manual (Page 103)

Some paper types cannot be calibrated. For all other paper types, calibration should be done in any of
the following circumstances:
● Whenever a printhead is replaced
● Whenever a new paper type is introduced that has not yet been calibrated with the current set of
printheads
● Whenever the environmental conditions (temperature and humidity) change significantly
You can check the color calibration status of the currently loaded paper at any time by pressing the
View information key on the front panel. The status may be one of the following:
● PENDING: the paper has not been calibrated.
NOTE: Whenever you update the printer's firmware, the color calibration status of all papers is
reset to PENDING.
● OBSOLETE: the paper has been calibrated, but the calibration is now out of date because a
printhead has been replaced, and should be repeated.
● DONE: the paper has been calibrated, and the calibration is up to date.
● DISABLED: this paper cannot be calibrated.
NOTE: Color calibration cannot be performed on plain paper, nor on any kind of transparent
material.
You can also check the color calibration status by using the HP Utility.
You can start color calibration in the following ways:
● From the HP Utility for Windows: select Color Center > Calibrate paper, and choose the
paper to be calibrated.
● From the HP Utility for Mac OS: select Paper Preset Management from the HP Color Center
group, choose the paper to be calibrated, press the button and select Calibrate Paper.
●
From the front panel: select the Image Quality Maintenance menu icon , then Calibrate
color.
The calibration process is fully automatic and can be performed unattended after you have loaded
paper of the type you wish to calibrate—which should be A4 or any larger size. The paper on the
active roll will be calibrated; you should ensure that the roll you want to calibrate is active. To change
the active roll, select the Paper menu icon
, then Select active roll.
The process takes about 3–5 minutes and consists of the following steps.
1. A calibration chart is printed, which contains patches of each ink used in your printer.
2. The chart is allowed to dry for a period of time that depends on the paper type, so that the colors
have time to stabilize.
