c203,253, 353 laser units

[EarthKmTech]

Today i changed another set for the first time in a long time on a c203.

had the constant error code, black polygon motor failing to rotate.

Its my understanding that another fault on some early laser units the SOS mirror used to come unstuck due to poor quality glue.

I intend to keep the remaining 3 good units incase of future emergency.

i opened the faulty black unit and fount the polygon motor totally seized, any reason i cant just swap this motor over with another one i come across in future to make a decent spare set again? the motor itself has no adjustments in mounting or electronically so i dont see why not.

Officially we are not allowed to open these things but rules are meant for breaking

haha, i certainly agree with you there, those ph units are crap.

otherwise ive had no real issues with that range other than the transfer belt retraction actuator debacle on early serial machines - that was a nightmare.

What i dont get is, on the c250 - c352 range i only ever replaced 1 print head set and it was destroyed by the operator attempting to clean them while coated in developer - end result, very poor print quality, the lense looked like it was cleaned with a kitchen scourer. never to this day have i had legitimate polygon or sos troubles on that range at all. the units must be quite similar in construction surely.
