Toner Supply Error - Ricoh D104 Field Service Manual

6. Troubleshooting
• B/W mode/ Normal or low speed for Special 3 Paper: SP2-852-001 to -004
• B/W mode/ Low speed for Special 4 Paper: SP2-783-001
• B/W mode/ Low speed for Special 5 Paper: SP2-833-001
• B/W mode/ Low speed for Special 6 Paper: SP2-883-001
If the result of step 2 is not satisfactory, change the settings of SP2-351-001 by -2 A or SP2-351-003
by -1 A again and then decrease the transfer current of the PTR for each paper type by 1 A until
-4 A from the default setting again.
Action 7
Increasing the transfer current for the PTR can solve the grainy image on small size paper. Use Special
4, Special 5 or Special 6 for the small size paper setting. It is because the adjusted transfer current for
small size paper is very different from the transfer current for normal paper.
Action Procedure
1. Increase the settings of the PTR transfer current corrections for each paper size until a grainy image
on small size paper is solved.
6
• B/W mode: SP2-791-005 to -017
• Full color mode: SP2-791-005 to -017
Action 8
Increasing the transfer current for the PTR can solve the grainy image on OHP in the full color printing.
Action Procedure
1. Change the setting of SP2-608-001 from 20 A to 18 A.
2. Change the setting of SP2-630-003 from 47 to 11.
3. If the result of steps 1 and 2 are not satisfactory, decrease the setting of SP2-608-001 by 1 A until
a grainy image on OHP in the full color printing.

Toner Supply Error

If the toner end message is displayed even though the toner bottle still has toner in itself, check the following
points.
1. Check if the setting of SP3044-001 to -004 is set to "4".
2. Check if the toner supply motor for each color works correctly with SP5804-071 to -074.
• Replace the toner supply motor with a new motor if it is defective.
