SOURCE: Oki C3300 toner replace, where do I stick the new chip

On the top left hand side of the cartridge, usually where the letter representing the colour of the toner (in your case M for Magenta) appears, there is a small removable section, about 15mm by 20 mm in size. Prise this open with your finger nail or small screwdriver. Remove the old chip and insert the new one in here.

It is more than likely that you have an incompatible toner fitted to the drum unit. Either a generic cartridge or b430 or b440 cartridge which is not compatible with b410's. Beyond that it may be a faulty drum unit. Hope this helps.

• Press either the + or – button until “ENGINE DIAG MODE” is displayed; press the Enter button and “DIAGNOSTIC MODE xx.xx.xx” will be displayed.
• Press and hold both the - & On-line buttons simultaneously until “ENG DIAG LEVEL2” is displayed.
• Press either the + or – button until “CONSUMABLE COUNTER SET” is displayed, press the Enter button; you are now in the menu to set various consumables.
• Press either the + or – buttons to scroll through the various consumables, at the desired consumable press the Enter button and the last digit of the count will start flashing.
• Press the Cancel button to decrease the digit amount or press the On-line button to increase the digit amount; press the + or – buttons to move along individual digits in the count.
• Once the count is at the level you desire, press and hold the On-line, Cancel, & Back buttons simultaneously until the “*” reappears next to the count; consumable’s count are reseted to the number you specified.
