X2 - Item 31 is the sensor in question. Also, it's quite possible you knocked something loose/out in the recycling unit when you inserted the transfer unit back in place.

[Problem]
SC 495 after 1 copy
[Cause]
If the toner collection coil sensor [31] does not change within 3 seconds after the drum motor turns on, then SC 495 (Toner Recycling Unit Error) is logged.
Paper dust built up on the toner collection coil sensor [31] and /or bad sensor.
Worn toner collection coil drive belt [1].
The transport coil [43 & 26] maybe clogged and cannot rotate.
1. Clean and check the toner collection coil sensor [33] with SP Mode 5-803-013, bit 5 should change from 1 to 0 or 0 to 1 when SP5-804-28 (Main Motor) is turned on.
2. Check that the toner collection coil drive belt [1] is not worn allowing for proper drive of the toner collection sensor pulleys [27 & 28].
3. Check that the toner collection coil [43 & 26] is not clogged, it can cause the toner collection drive belt [1] to slip.
