developing rollers

[tcypy1961]

does any one see any reason why I couldn't use a developing roller from either a Ricoh 1035/45 or 2035/45 in a Ricoh 350/450. As I was thinking about this throughout the day the only reason I would think not would because of the doc. blade gap???
Thanks!!!

You might have a slight doctor blade gap issue, but I'm thinking more along the lines of dealing with the mag roller brush height and exactly where the dv stands up on the roller. In that case, the doctor blade would not help too much if the brush height was off by five or ten millimeters.

Why would you want to ?

He's trying to keep up his 5.2 calls per day, and this can be one of those "calls" that he just keeps going back to!!!!

My guess would be that he doesn't have a replacement 450 dv assembly, but a boneyard 1035 sitting at the shop just begging to be scavenged.

I didn't think about trying to keep up with a certain # of posts. The reason for using the 1035 mag roller over the 350 is for the reason one of the replys gave is I don't have any usable 350's but I do have 1035/2035's. Is the mag. brush height preset or is it adjustable???
Thanks!!!

It's been awhile since I've seen one of their dv units. I THINK the brush height is non-adjustable, as this is probably a good thing cuz' once it's out-of-adjustment it can be a real pain to get back to spec.

You can probably eyeball it to see where the brush height is at its peak.

I would just try one to see what happens. The only thing the brush height would affect would be copy quality and it MIGHT cause some premature wear on the drum. Sometimes, you won't know what works until you give it a shot!!! Given some of the similarities of the machine designs, I would say that it will work and may only look a little poor if anything.

Oh, I was just referring to service calls per day. Just tell the company, "Uh, I have to go back to that MacGyver machine I've been tweaking with for six weeks now!!!" It would murder your recall stats though.

If you have the doc blade gap too tight or loose you will either end up with light copies until process control dumps a bunch of extra toner in the mix then backgrounding and dusting (think MP4000 without the buildup) or grainy low contrast copies possibly with spilled developer. Either way its not good, but I think these machines are close enough that it's worth a try. Ricoh does not publish specs on the proper gap - only that it's adjusted at the factory using special equipment and should not be tweaked in the field. I have seen them tighter on one side, and have successfully adjusted them with a set of feeler guages oldschool style - so much for the precision factory adjustment...
