• The servicing alert messages are not displayed when SP5930 001 (meter click charge) is set to "Yes".
The default setting of SP 5930 001 is “No”. For more, please refer to "5. Service Tables".
At about 200 pages before this (based on A4 prints at 2 pages/job), the machine detects toner near-end.
At this time, ‘Replace Print Cartridge Soon’ is displayed.
• Note that toner can run out more quickly 200 pages after near-end, if the coverage ratio is high.
Because of this, after toner near-end, printing quality cannot be guaranteed.
Toner Overflow Prevention
With the main motor rotation count feature, the machine can be set to stop printing after the print total
exceeds a certain set value. If the print count exceeds this value, then ‘Replace Print Cartridge’ remains in
the display. Then a new AIO cartridge must be installed.
This feature is a safety measure to prevent the used toner tank from becoming full (there is no toner overflow
detection mechanism).
To enable this feature, you must set SP3923 (Cartridge Stop) to "Yes".
Why do we need this feature?
Normally, the AIO is replaced by the user at about 15k. But some users will refill the old AIO with toner,
and use the same AIO again. If this occurs, the used toner tank will not be emptied. So there must be a
way to stop users from repeatedly filling the old AIO with fresh toner.
If you enable SP 3923, then after a certain number of prints are made with the same AIO, the machine
prevents printing, and a completely new AIO must be installed. If you try to print again by removing/
replacing the old AIO or adding new toner or other trickery, there will be no printing.
How does the machine know if the AIO is a new one?
The AIO has serial number information on a chip. The machine checks this number when the AIO is
placed in the machine.
Why is this feature disabled?
Ricoh does not support the practice of refilling old AIOs with fresh toner, so the feature is disabled by
default. But if field service stations know that this practice occurs in their region, or they know a customer
who is doing this, then they can enable the feature.
