HP Color LJ 5550

[pfeifft]

I have a HP Color LJ 5550 that gives an error of 51.2c. A cold reset has been performed and the cyan toner has been replaced. After replacing the cyan toner another cold reset was performed per HP's website. According to HP's website this is a laser error and also affects the cyan toner. Any help on how to proceed from here would be great! Thank you.

Being an in-line configuration, there are four lasers. A lot of work to replace.
If you are able to do major tear-down, let us know, and will try to give a quick instruction. {Tho' it's quite a bit to do}
