Frequently Asked Questions

Which consumables does the OKI B4550 use?

The B4550 uses the 43502001 family, with the toner cartridge and image drum as separate replaceable units. It is a fast monochrome printer aimed at small workgroups.

My B4550 leaves repeating dots down the left margin. What is it?

Repeating marks at fixed intervals are the signature of a damaged or worn image drum. Inspect the drum for scratches; if you find any, the drum needs replacing even if the toner still has life.

What paper weight can the B4550 handle?

It handles standard office stocks plus heavier media through the multipurpose tray within its rated range. Always match the driver's media setting to the actual stock so toner fuses correctly and does not flake off.
