●
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 T7100 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.
The T7100 Monochrome status code consists of 8 digits, one for each group of nozzles, in the
following order: matte black 1, matte black 1, matte black 2, matte black 2, empty, dark grey 1,
empty, 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)
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).
