Automatic Mist Cleaning - Ricoh D124 Detailed Descriptions Manual

6.8.6 AUTOMATIC MIST CLEANING

The condition of the print head nozzles can deteriorate over time due to ink that starts
to cling to the nozzles and accumulates inside the suction cap and the three
protective caps of the maintenance unit. Paper dust can also accumulate and
interfere with the operation of the nozzles.
The illustration above shows droplets of mist
can collect near the nozzles. This undesirable condition is corrected with periodic
automatic cleanings while the printer is in use, greatly extending the length of time the
machine can be used without operator intervention.
 Mist count. A "mist count" triggers automatic cleaning. This mist count can be
extended to increase the timing between automatic cleanings. The mist count,
which determines the intervals between automatic cleanings, has been doubled
for this machine.
 Count adjustment. The count is automatically adjusted for the width of the paper
and total print area.
 Paper dust count. The paper dust count (the total number of pages printed,
cutting count) are used to determine when cleaning is done for paper dust.
