17) If the Bk Toner Feed Assembly is turned, the claw [9] may hit against the PCB behind the assembly. To
prevent this, pull the assembly toward the front a little while turning it right down.
18) Replace the Toner Feed Assembly with the countermeasure part (FM3-8084-010). This measure has a
mechanism added to drop toner adhered to the toner level detection sensor window in the Toner Feed
Assembly by vibration.
19) Put together all the removed parts in the reverse order of removal.
[Caution] When you install Bk Toner Feed Assembly, please confirm the caution in Step 14.
20) Turn on the main power SW.
21) If the machine's software has a combination of less than MN-CONT Ver.20.70/DCON Ver.40.03, update
to MN-CONT Ver.20.70/DCON Ver.40.03 or later.
[Caution] If the versions are less than the above, Service Mode in step 23) cannot be performed.
22) Check the numerical value of the affected color in Service Mode > COPIER > Display > DENS >
DENS-K. You will see a numerical value close to -4.00% to -6.00% displayed, then if E020-03b1 occurs, the
a numerical value will be over the -5.00%.
23) In Service Mode > COPIER > Function > INSTALL > SPLY-H-K and press "OK". "START" will be
displayed for a moment in Service Mode display and then "OK!" will be displayed. This allows the initial
filling of toner from the toner bottle to the hopper unit.
24) Open the front door of the machine and insert the door key switch into the door open/close sensor switch.
Then the operation of toner supply to the buffer unit starts and lasts for approximately 40 seconds. Make
sure that the toner bottle rotates intermittently. If the toner bottle does not rotate, check for the Toner Feed
Assembly Attachment.
25) Place A3 blank sheet on the copyboard glass and make 21 copies. This allows toner to be supplied in
the developing assembly.
26) Check the numerical value of Service Mode > COPIER > Display > DENS > DENS-K. You will see a
numerical value close to -1.00% to -2.00% displayed as toner was supplied in the developing assembly.
