instructions on the front panel. The following screen appears.
The lists show the number of clogged nozzles in each die for each agent, Detailing Agent (DA) and
Fusing Agent (FA).
For example, in the above example, the die that is closest to the front of the printer, which is Printhead
3, Die 5, has 4 clogged nozzles in the Detailing Agent and 13 clogged nozzles in the Fusing Agent (blue
balloon).
How the Health Gauge relates to the number of clogged nozzles
The following table summarizes the relation between clogged nozzles and the Health Gauge.
Bear in mind that the analysis in the printer is more thorough, and takes more into account than just the
number of clogged nozzles.
Table 12-1 How the Health Gauge relates to the number of clogged nozzles
Clogged

Any time the number of clogged nozzles in one or more dies/agents in one printhead is more than 900
(maximum is 1056), it is very unlikely that so many nozzles became clogged suddenly. Therefore, these
are the possible causes:
● They could be genuine clogged nozzles after some damaging event such as, for example, the
carriage crashing into the material. In this case, follow the guidelines in
printheads show these defects on page
● There could be a problem with the drop-detector calibration. Tap the Settings icon
Utilities > System tools > Calibrations > Drop-detector calibration.
