7302 Paper Dust Count DFU
This SP is used to set the threshold value of the paper dust count that triggers Auto
Cleaning. The nozzle condition can deteriorate over time due to ink that starts to cling to
the nozzles and accumulate inside the suction caps of the maintenance unit. Paper dust
can also accumulate and interfere with the operation of the nozzles. Periodic automatic
cleanings execute while the printer is in use, and greatly extend the length of time the
machine can be used without operator intervention.
The paper dust counts (the total number of pages printed, cutting count) are used to
determine when cleaning is done for paper dust.
