C4503 vs. C4504 similarity

[ABS tect]

Developer units definitely different. I've tried. Pcu themselves are the same.

Hmm interesting.... I'm about to be getting into the '04 series and was hoping to buy '03 for the guts to replace.

Good to know... Now is the actual developer powder different? I've come across some generic toner that says you can use in both 03 and 04... So was curious if the toner ingredients are the same wouldn't the developer also be?

Toners are the same.

Developer units the same?

Developer units NOT the same

Given the issues I have seen at times with 03 series devo units, I would not be putting those into a newer machine and instead want the newer version of the devo units. PCU's are fine as others have mentioned.

Just my two cents.

The parts within the PCU are the same ie drum, blades, charge etc but the frame is different but if you order the latest part number oem 04 pcu they will fit into 03 but not 03 into 04. The 04 pcu's are cheaper from ricoh than the 03 series pcu's

I found that it makes a significant price difference in the 30/35 ppm models. I'm not sure if the PCU's are exchangeable between the 04 and 03 series for those models.

does the developer unit mount inside?
TRicky rico likes to swap wires and sometimes muck with the td sensor under the dev unit...
I feel like "MONK" sometimes when i have to use a printer part on a copier unit..
Recently had a mpc2551 that would not accept a mpc2550 PCDU....
TD sensor was the difference
