Displays at toner near-end (based on the toner end sensor), or
when the print cartridge is near the end of its service life
(based on main motor rotation).
Printing can continue but print quality is not guaranteed.
The print cartridge is at the end of its service life (about 200
pages or more after near end is detected by main motor
rotation) but some toner still remains (toner end sensor did not
detect toner end).
Printing can continue but print quality is not guaranteed.
This condition will occur if an old AIO is refilled with toner. The
grey area in the diagram is marked 'out of guaranteed range'
because Ricoh cannot guarantee the operation of the machine
if an old AIO is refilled with toner.
Toner is exhausted (200 pages after the toner end sensor
detects near end), or the toner overflow prevention
mechanism is triggered (based on main motor rotation).
Printing cannot continue and "Replace Print Cartridge" will
remain in the display until the AIO unit is replaced.
