After getting message 1700 "Ink absorber is almost full" I was able to remove and clean the ink absorbing pads and reset the counter. The message no longer displays. However, is there a larger ink absorbing unit beneath these pads, that once full, the printer will no longer function? And if so, how long between this initial warning code and failure to print? I realize that may depend on print volume but a ballpark figure say 100 pages, 1000 pages? Last, if there is a waste ink reservoir, can I replace it?
