Review on Inkjet MFP Canon PIXMA MG2540S, color, A4 by Janis Saikovskis ᠌

Refilling cartridges. First, we launch the factory software. Canon Quick Menu, Starting My Printer, Printer Settings, Maintenance, Printer Status Information, Options, Untick Enable Status Monitor. 1 Press the STOP button for 15 blinks, turn off the power and remove the cartridges. 2 Peel off the stickers and drill holes in the round depressions in the plastic. 3 Pour paint through syringes in strict order! 1 (upper cavity) red paint 3 ml, 2 (left cavity) blue paint 3 ml, 3 (right cavity) yellow paint 3 ml. During pouring, the paint may flow from the nozzle, protect the surface of the table from the practically indelible paint! 4 After refueling, install the cartridges, turn on the power and hold down the STOP button for 5 blinks. 5 We use until the heads in the cartridges die. Googled the bonus. On this printer, you can permanently turn off the ink level, not programmatically, but at the hardware level. To do this, you need to completely empty the running out cartridge, running a few pages, until a corresponding warning pops up that the cartridge is empty. Then, without closing this warning, hold down the yellow button on the printer for 10 seconds. Ink monitoring for this cartridge is permanently disabled. In general, it’s better to buy a normal MFP that costs from 5k, everything below is just some kind of consumer goods with truncated functionality.
