Ricoh aficio 2035 engine strange background image problem using 8 1/2 x 11R only??

[tonerjockey]

i posted a few days ago about background. this is a Lanier LD 235, but uses the same drum etc as the aficio 2035, 3045 etc. the machine has a new drum, blade, PCR, brush, fuser rollers. i have removed the mag rollers and cleaned them, verified the erase lamps are working.



I did find a strange phenomenon though. as I said, the heavy background, and the reverse double image isnt on the edges, and also only on the top and bottom third of the page. the center of copies is fine.

I made a strange discovery. when the paper is loaded 8 1/2 x 11 the copies are perfect. if the paper is loaded 8 1/2 x 11R in either drawer, it does this. and the first copy is always fine. if you run 5, it gets progressively worse.

this just doesnt make any sence unless there is some setting to adjust that size letter long to change the charging parameters for ? special paper.
does anyone have any ideas what could be causing this? have a nice day, Jim

Old machine....
Have you remove the 2nd (redundant) drum blade from the PCU?
Have you've vacuumed out the transfer unit etc... ?
Have you tried a new transfer cleaning blade , belt etc... ?

Post an image of the problem to the forum.

did u check charge roller and bushings ?

Is the ground bracket for the development unit in place. They tend to fall off when dumping the old developer and get thrown out.

Hi Guys. yes, after it happened, i replaced the drum, no change, the charge roller, no change, i checked the grounding clips and cleaned them. i had vacuumed out the transfer unit a 1000 copies ago. transfer belt blade was done a while back, but not when i did all the replacements. the machine does not have the second cleaning blade. i took that out a few years ago for some issue it had. the Hytec tech said there was some setting for acid paper, but at the time i didn't ask anything about that. now i am wondering if the machine can be set for different electrostatics when using a different paper size or direction. but now i am thinking, i don't know if they had the paper this direction before. must have and it never had this prior. letter R is bad, letter regular direction is fine. i can email a sample but it wont look exactly like the copy. of course now my computer isnt displaying the PDF i scanned so will reboot and send later.

You can get paper that is ammonia coated or impregnated or something, that's what the adjustment is for, so you don't have to worry about that. You shouldn't have to change anything other than paper size settings for different paper size or orientation.

that's what i was wondering. could that setting cause this issue on plain paper if it was set that way?

I don't even know if that machine has that SP setting.

Image Density Adjustment

Adjusts image density. Changing this setting adjusts development bias and ID sensor output voltage that in turn raises or lowers image density. [1 ~ 5 / 3 / 1 step]

Try checking this and seeing if it has changed from the default of 3

i cant seem to get the samples to attach.

I am not sure by what you mean with the R and non R setting of paper size. I am assuming you mean portrait or landscape or the SEF / LEF. This model does have different transfer voltage based on paper size but it I think only changes if smaller then 8.5 width and/or if your running thicker paper settings using the bypass, so unless your dials are registering incorrect widths of paper settings this shouldn't really change. You should be able to set the paper size in the user tools and set the dials.

The sp2301 on through 2309 have to do with transfer currents and paper size adjustments for voltage applied on the belt, the belt does adjust voltage at leading edge to image area. I think this is probably over complicated it would be more likely to have bad contacts or transfer belt unit. If your getting background though it sounds like there is to much voltage on the transfer belt pulling excess toner causing shading.

Like i said though i dont know what you mean by the R in your paper size description i could be way off on my thinking.

Hi, yes the "R" i was referring to is loading the paper in the drawer so its lead edge is the 8 1/2 width. the non "R" is loading the paper the other way in the drawer so the lead edge, ( the edge that is being pulled by pick up rollers and enters the machine first, ) is the 11 inch side. back in the day, that is what that direction drawer was labeled. before portrate and landscape i do believe. like i said, two distinct areas of background on parts of the copy with a ghost image of the test pattern things but not a black double image but the test pattern name for example is white or hollow within the background area.
i haven't been back yet to check those voltages and settings. i really appreciate your input. now get out and vote. have a nice day, Jim

In the future you might want to use the current terminology of SEF and LEF. "R" and "non R" are from the analog days and referred reduction of 11 X 17 to 8 1/2 X 11. With digital models it no longer has any meaning since the image can be rotated in memory.

ok, understood. can you tell me what those acronyms mean? and hopefully i will remember when i need to reference in the future.

SEF = Short Edge Feed
