Frequently Asked Questions
Which toner cartridge does the OKI B4350 take?
The B4350 uses the 42103001 standard black cartridge, and there is also a high-yield option, the 42102901. Both are black cartridges — there is no separate color set to manage since it is a monochrome printer.
Is there a high-yield toner for the B4350?
Yes. Alongside the standard 42103001 (about 2,500 pages), the B4350 takes the high-yield 42102901 (about 6,000 pages) — more than double the output per cartridge, and both are listed on this page. Track your monthly page count and keep one spare on hand so a heavy month never leaves you waiting.
The B4350 says toner is low but I barely print. What should I do?
The low-toner estimate is based on page coverage, not age, so light users can print for a long time after the first warning. Remove the 42103001 cartridge and rock it gently side to side to redistribute toner, then reinstall it.
