Ricoh V-C3 D081 Field Service Manual page 539

1.Replace the toner cartridge causing the problem (density too light or no "Toner End" release) with a new
toner cartridge.
• After the "Toner End" alert appears for a color, this "Toner End" information is written into the ID chip
on the toner cartridge, even though a lot of toner may remain inside the cartridge. This means that
machine will detect that the toner cartridge is empty.
2. Follow the procedure in the service manual to replace the developer for all colors.
3.After the TD sensor initialization (SP3801-001 to 006) has been completed, check these SP values:
• SP3812-001 = 1111 (Display Result of Developer Setup Execution)
• SP3821-001 = 10101010 (Display Result of Process Control)
Procedure 2
1.Replace the toner cartridge causing the problem (density too light or no "Toner End" release) with a new
toner cartridge.
• After the "Toner End" alert appears for a color, this "Toner End" information is written into the ID chip
on the toner cartridge, even though a lot of toner may remain inside the cartridge. This means that
machine will detect that the toner cartridge is empty.
2.Do SP2251-001 to 004 "Forced Toner Supply for the color (K, M, C, or Y) for the color whose image
density is too light.
• To avoid damage to the toner supply mechanism, never perform "Forced Toner Supply for K, M, C,
or Y more than three times.
3.Check the image density to see if it is darker.
4.Do SP3820-002 (Manual ProCon).
5.Do SP3821-001 (ProCon OK?) to confirm that SP3820-002 succeeded. YOu should see "10101010"
displayed if SP3820-002 executed successfully.
• If SP3820-002 displays any values other than "10101010" (successful execution), the toner supply
mechanism may be broken. Replace the toner supply mechanism.
6.If SP3820-002 shows "10101010" (successful execution), perform Steps 2 and 3 of Procedure 1 for
the color causing the problem (light image or failure to release from "Toner End" alert).
Procedure 3
• For this procedure there must be developer in the development unit.
