Ricoh D0A0 SPC360SFNw

Problem

• SC332-** (Toner supply feed lock (01: Bk, 02: C, 03: M, 04: Y) occurs during operation.
• The machine can be restored temporarily by switching it off and then back on. The problem reoccurs after printing a number of pages.

Cause

• The PCDU's protruding part (at the right of the shutter) fails to lift the shutter and the shutter stays closed, failing to supply toner to the PCDU, resulting in SC detection.
• The toner cartridge gear [A] and the middle cover gear [B] are not connected, failing to supply toner to the PCDU, resulting in SC detection.
• Toner has clogged in the toner supply port of the toner cartridge.
  Note:
  Open the toner cartridge's outer and inner shutters and check the toner supply port. If the toner is clogged, it will not come out even if you hold the cartridge with the supply port facing down and the shutter open.

1. Reinstall the toner cartridge with the middle cover closed [A] to make sure that the shutter is properly lifted.
2. Open the middle cover and make sure that the toner cartridge gear [A] and the middle cover gear [B] are engaged. (Left: not engaged, Right: engaged)
3. Eliminate the toner clogging in the supply port of the toner cartridge, shake the toner well, and then reinstall the cartridge.
4. If the problem persists even after performing Steps 1 and 2, replace both the PCDU and the toner cartridge.

Checking Toner Supply to PCDU

1. Execute SP3-017-001 (TnrRmnSnsFc) and SP3-017-002 (TnrRmnSnsBk).
2. Execute the SPs below, and then check the category of the LED used for the toner-end sensor for each color.

   Toner End Sensor	SP	No. to be identified/LED category
   BK	3-244-009	29: Category 1 31: Category 2 27: Category 3
   C	3-244-016	9: Category 1 5: Category 2 4: Category 3
   M	3-244-015	21: Category 1 20: Category 2 16: Category 3
   Y	3-244-014	24: Category 1 23: Category 2 20: Category 3

3. Check the output count of each color toner in the following SPs.
   • SP3-411-005: SnsOutCntAvK
   • SP3-411-006: SnsOutCntAvY
   • SP3-411-007: SnsOutCntAvM
   • SP3-411-008: SnsOutCntAvC
4. The amount of the toner is adequate if the [SnsOutCnt] values are within the range of the following table:
