Main Motor Rotation Count - Ricoh G176 Service Manual

Printing Process
The 200 page limit for after the near-end alert appears can be adjusted with
SP2213. However, the print quality of these pages cannot be completely
guaranteed. This is because the 200-page limit is calculated for A4, with a 5%
coverage ratio (depending on the coverage ratio of these 200 pages, toner could
run out before the 200 pages are made).

Main Motor Rotation Count

The time to replace the AIO cartridge can also be determined by the length of time the main
motor has been rotating.
When toner end is detected, 'Replace Print Cartridge' is displayed alternately with 'Ready'.
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.
