HP Designjet T7200

If all digits are 0, printhead alignment is pending. In this case, perform printhead alignment.
If you see 3, 4, 6 or 7 anywhere, the results of the pattern scan are worse than expected. Try loading photo
paper to ensure that the problem is not the paper. If the problem persists, calibrate the Line Sensor; if the
problem still persists, replace the Line Sensor.
If you see 2 or 5 anywhere, the pattern scan is OK, but the corrections are out of the expected range. Try
reseating the affected printhead(s) and then perform the alignment again. If the problem persists, replace
the affected printhead(s).
Closed-loop color calibration
The T7200 status code consists of 16 digits, one for each group of nozzles, in the following order: empty,
yellow 1, empty, yellow 2, magenta 1, cyan 1, magenta 2, cyan 2, matte black 1, matte black 1, matte black
2, matte black 2, light grey 1, dark grey 1, light grey 2, dark grey 2.
Each digit can take one of the following values:
●
0 : no data, or error
●
1 : corrections OK
●
2 : corrections at risk (level 1)
●
3 : corrections at risk (level 2)
If all digits are 0, color calibration is pending for this paper type. In this case, perform color calibration.
If you see 3 anywhere, the corrections are out of the expected range. Try repeating the color calibration. If
the problem persists, replace the affected printhead(s).
