Mpc4502 black smear offset

[mrfuser]

Got a client with the 4502 that suddenly started to smear on the op side of pages. Swap the drum with the same result . Color pages look fine just the black is a problem .

Is there something going on with the fuser possibly on this?

Hi there!
Yep! My 2 cents on the fuser, it may look OK, but after a time it smears. When the old sleeve-roller is installed, the problem occurs earlier.

Yep, right on the money! Fuser. Odd, fuser looks absolutely fine and only has about 100k on it. Time for a rebuild I suppose. Any thoughts on best place for parts for these fusers?

Get the printer version (SPC830) and simply swap the wiring loom over. Sounds tricky but it's super simple. Disconnect the thermistors and feed the wires out of the base plate, leaving the thermistors in place on the fuser itself. Swap out the entire wiring harness and you're done. The printer version comes with a new transfer roller also. If you aren't an authorized Ricoh dealer, order the fuser from Pro Vantage. I'm told they have the best prices for the grey market. I've seen these fusers with less than fifty k and the copy quality is terrible (light copies,etc) Freaked me out the first time I put in a new fuser and the solids came right back. I haven't had much luck replacing just the the heat sleeve.

Re: Mpc4502 black smear offset

My guess is there won't be a bulletin on this one. No one wants to admit these fusers are the week link on this series......

Re: Mpc4502 black smear offset

Anyone? Someone must have that bulletin still. It is the one that has you change temps and such on the fuser to stop the smearing.

Anyone?

At one point replacing the fuser motor was a compulsory mod.

I didn't know that fuser fit in these, we used to use them on the older generation models. Those sleeves only last around 100k on average I get lucky sometimes and get one that goes pretty far. Its probably cheaper to get the d144 part then the whole spc830 fuser, it only takes about 25 mins to replace it.
