Frequently Asked Questions
Which cartridge fits the Oki B4300?
The B4300 uses the Oki 42103001 toner cartridge. As a monochrome printer it needs only this single black cartridge, with no color set to manage.
My B4300 prints have vertical white lines. Is the 42103001 cartridge empty?
Vertical white lines usually mean low toner or a dirty LED array. First try redistributing the toner by rocking the 42103001 cartridge side to side. If lines persist with a fresh cartridge, clean the LED printhead strip inside the printer.
How do I get the most pages from a 42103001 cartridge in the B4300?
Use draft or toner-save mode for internal documents and reserve normal quality for final copies. Coverage is what drains toner fastest, so avoid printing solid-black graphics you do not need.
