Samsung SCX-4521F Fuse

[Guest]

I have a client using remanufactured laser cartridges, seems the "CRU Fuse" error comes up after installing a new cartridge, we have tried 2 remans. so far and both times the error has come up. We pulled each cartridge, and the fuse had not blown. So is the fuse the wrong one, or is the printer at fault?

When the SF-5100 first came out, we had problems with remanufactured cartridges not blowing the fuse. I assume that the fuse did not make contact with the metal tabs inside the fax. I would suggest trying a Samsung brand cartridge instead of a remanufactured one.
