Up to now the Samsung SCX-5935 have been our most successful placement, fast, low cost per copy, our wholesale cost of OEM cartridge at $62.00 per 10,000 copies, that is 6/10 of a cent for drum and toner, not bad. Just now I have a heck of a problem with the ADF, I can feed single sheets all day without a hitch, but as soon as I put 2 or more sheets in the ADF, the second sheet will l not complete the scan and goes into jam mode. The weir thing is if I put a stack of paper on the ADF and apply a slight pressure to hold back the originals, it might just feed every page correctly without a jam. This is happening to 3 locations and I begin to suspect it might be a timimg problem, has anyone run accross this ? Thanks.

Re: SCX-5935 ADF problem
What feed count on the DF? What jam codes? Have you cleaned or replaced anything? That's always a good place to start: cleaning and examining the typical pickup feed an separation components. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Re: SCX-5935 ADF problem
It's a 5935 right?? what version of frimwar (firmware for those that don't get it) is it running??? Sammy updates this constantly ........for weird issues......
BC's input is also very solid on what to check for with the hardware!!!!!!!!!Mystic Crystal RevelationsComment

Re: SCX-5935 ADF problem
did more than that, replaced the feed assembly as well as the dfp pad. What I noticed is that the second does not wait until the first sheet exit completely., it must be the feed solenoid staying on too long. I have repaired a lot of paper feed problem where the feed solenoid is sticky and feed more than one sheet at a time, I think this may be similar , but it is a bitch to open the adf cover to check.Comment

Re: SCX-5935 ADF problem
Problem solved, after dissasembling and assembling the ADF 4 times in the weekend, ignoring elementary physics I finally realizing it was residual magnetism that caused all my problem. The original paper feed solenoid core material wasn't soft enough and it eventually developed enough residual attraction to keep the relay activated after years of magnetising cycles . 3 layers of friction tape between the coil and the pawl did the trick. , I see this can be a real problem as we have 3 cases out of about 100 placement of the SCX 5935. The same problem will also affect paper feed as it basically of the same structure, I alreally run accross it . too bad I didn't connect the two faults together!Comment

Re: SCX-5935 ADF problem
I too have seen this in paper feed and adf, often it was a foamy pad that stopped being foamy and started being sticky, and if you remove the pad entirely, the residual magnetism thing happens... a few layers of black tape take care of that in the feed and both solenoids in the adf.

Re: SCX-5935 ADF problem
change the ADF rollers and separation pad, that's always works for me.. you can clean the adf roller with a mild soap and water combo, but the separation pad must be changes its wears away..
also check if the spring is there, the spring holds back the adf, I think there an updated version now, no spring needed..Comment
