Greetings from Berlin Germany

The toner cartridge has a chip that calculates the estimated usage of the toner and once it reaches it's capacity (per estimation), it will not print. The only thing you can do is to buy a new cartridge or buy refill toner that comes with a reset chip.

Yes it should. The sellers often reuse the cartridges and so it will fit in just fine.

Mr Stephen You have to check paper settings at 3 places first that you are putting correct paper size in correct tray and the paper supporter is touching the paper. Secondly your documents page setup paper size. Finally go to printer properties and under paper selection you will find letter size change it to a4 Thankyou for using free solutions at yafix-ratings from your side would be appriciated.

18H: Heating roller warm-up failure

1 Check the fusing unit for correct installation (whether it is secured in position).
2 Check the fusing unit, DCPU1, and PRCB for proper connection and correct as necessary.
3 Check the lever of the safety switch and correct as necessary.
4 Change the fusing unit.
5 Change PRCB.
6 Change DCPU1.

I believe the duplex door is in the back of the printer.

Need to set A4 size default on the printer driver itself.
Go to Printers and Faxes / Konica Minolta 2490MF right click/ Printing preferences /
Create a "Easy Set" with a new name. Set all paper sizes to A4. Save the new settings to the new Easy Set.
Click apply.

should be o.k.

Konica before fixing the issue used to ship out the controller board.
Now a simple firmware upgrade will solve your issue
