Re: overflow developer. why?

1) Check the version of DCON. If it is v21.01(iPRC1) or v7.01(iPRC1+) or earlier, upgrade it to the latest one.
(The following control in service mode is added changed in v21.01(iPRC1)/v7.01(iPRC1+) or later.)
2) Set "3" in service mode > COPIER > OPTION > BODY > DEVL-VTH.
3) Check the color where developer overflow occurs. If it occurs in black only, go to step 4); if it occurs also in
other colors, go to step 6).
4) Set "54" in service mode > COPIER > ADJUST > DENS > P-TG-K.
5) Set "30" in service mode > COPIER > ADJUST > DPC V-CONT > VCONT-K and go to step 8).
6) Set "54" in service mode > COPIER > ADJUST > DENS > P-TG-Y/M/C/K.
7) Set "30" in service mode > COPIER > ADJUST > DPC V-CONT > VCONT-Y/M/C/K.
8) Replace the concerned developing assembly or developer.
9) Clean the ATR sensor.
10) Execute aging.
Set "5" in Service mode > TEST > PG > TYPE.
Set "1" in Service mode > TEST > PG > TXPH.
Set "0" in Service mode > TEST > PG > THRU.
Set "128" in Service mode > TEST > PG > DENS-Y/M/C/K.
Set "1" in Service mode > TEST > PG > 2-SIDE.
Set "20" in Service mode > TEST > PG > PG-GTY PG-QTY.
* Use A3 or larger paper.
11) Run automatic gradation correction (full correction).
Points to Note About Service Work:
The above measure may cause such adverse effects as decreased Dmax density of the color concerned or
worsened speckle (dots with low gloss on image).
Neglect of replacing the air filter of the printer on a periodic basis may cause developer overflow from the
developing assembly due to the temperature rise in the machine. Replace the air filter by 250,000 sheets passed.
