[Error Code] MPC 5503 - SC362-04

[copier tech]

Hi all, any ideas on this one, I recently installed a reconditioned MPC 5503 all was fine but now it is now throwing SC362-04 (yellow TD issue ?)

During the refirb we replaced all 4 devs & the black PCU, & updated all the firmware etc.

A few days after delivery it threw this code, I attended & removed the yellow PCDU, checked the dev connection, it all looked fine, I fitted it back, ran 50+ colour test prints fine, but the next day it had come back in!

Sounds like a faulty dev unit. Replace the Y dev unit. Make sure that the unit is initialized correctly, monitor the Vref and Vt to make sure the TD sensor is working correctly. Make sure toner is getting to the dev unit as well.

Hi, I replaced the yellow dev unit (again) & so far it's running fine

Many thanks
