Question about Brother MFC 7840W Printer
The copier stops when the MACHINE detects the toner is low. How can I cover up the "Toner eye", so that it will keep printing and use up the toner in the machine until I say it is low?
If you know where the "Toner Eye" is in the copier, cover it with black tape. Usually though, the copier counts the number of pages printed and then at a predetermined number thinks toner is low and stops printing. If the toner cartridge is chipped (has a electronic chip) it keeps the count in there. These type of cartridges are refillable, but still have the "Empty" count. The counter must be reset. These resetters are hard or impossible to get.

Tips for a great answer:
Sir/mam Power off the machine. Then remove the toner bottle be careful the hole might be on the bottom toner is going to go everywhere. Then close the front cover and turn on the machine. Let the machine go through it normal routine. When it asks for toner install the toner correctly. If THE KUNB on the side of the bottle is damage put a new one in that KUNB is what the toner motor uses to turn the bottle if it damage you get a code. If that does not work you might have a bad motor or the home sensor or actuator for the toner bottle is bad worse case the control board is bad
