HP Designjet T7200

●
3 : nozzle health at risk (level 2), printhead in warranty
●
4 : nozzle health OK, printhead out of warranty
●
5 : nozzle health at risk (level 1), printhead out of warranty
●
6 : nozzle health at risk (level 2), printhead out of warranty
If nozzle health is at risk, you are recommended to check the maintenance cartridge, and replace the
printhead if necessary.
If all digits are 0 or more than 50% of printheads are at risk, check the Drop Detector (cleaning it to verify
there are no fibers blocking it), perform a Drop Detector calibration, and replace it if the problem persists.
Media advance calibration
The status code consists of 8 digits, each of which can take one of the following values:
●
0 : no data, or error
●
1 : parameter OK
●
2 : parameter at risk (level 1)
●
3 : parameter at risk (level 2)
●
8 : non-navigable paper type
●
9 : OMAS disconnected
If all digits are 0, media advance calibration has not been performed on that paper type. In this case, perform
media advance calibration.
If the 4th or 7th digits are not 1, there is some mismatch between OMAS and the printer calibration. Clean the
Media Advance Sensor, and replace it if the problem does not disappear.
If you see a 9 anywhere, the OMAS sensor has been disconnected. Clean the Media Advance Sensor, and
replace it if the problem does not disappear.
If you see a 2 or 3 anywhere, the calibration has not worked well. Check that the paper is correctly loaded and
that the calibration is correctly printed (otherwise clean the printheads), and try the calibration again.
Printhead alignment
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 : scans and corrections OK
●
2 : corrections at risk (level 1)
●
3 : scans at risk (level 1)
●
4 : scans and corrections at risk (level 2)
●
5 : corrections at risk (level 2)
●
6 : scans at risk (level 2)
●
7 : scans and corrections at risk (level 2)
