EstimuloVisual Posted February 9, 2009 Report Share Posted February 9, 2009 Hi !! I have this problem with my Frontier 370, when i make only 4x6" prints, (I didn´t try in a smaller size). Not always but somedays the prints come out overlapped, so the counter sensor check one print, not two. And then the alarm sounds, "paper jam in dryer section". So, i tighted all racks springs, i tested all crossovers, and the problem still appears. If you have the solution to this trouble, please let me note!!!

MasterLaser Posted February 9, 2009 Report Share Posted February 9, 2009 Check gears and shafts on crossover racks and gear spur on rack, as well as COVER and gear next ti him on every rack especially PS. Replace as needed. Quote Link to comment Share on other sites More sharing options...
EstimuloVisual Posted February 9, 2009 Author Report Share Posted February 9, 2009 I did that, and everything it´s OK, also i tighted the springs... :-/ anyway, thank you!! Quote Link to comment Share on other sites More sharing options...
manager Posted February 9, 2009 Report Share Posted February 9, 2009 On our Frontiers, the prints usually overlap because of the dryer's net wich is most time too tight because of the spring that stretch it. I don't know how Frontier 370 is, but you must know that the net doesn't push or pull prints, just guides them, so it can be almost loose and still function properly. So, if you can attach small rings or anything to that springs, just for a test, you can see if it is from there or not. and if it is, then you can modify permanently the spring. I don't know how Frontier 370 is inside, but if it doesn;t help you, my answer may help others. Also, crossovers' locks get loose sometimes and not touch the racks system correctly stepping fractions of rotations sometimes, but this is kind of hard to notice.

eoughphily Posted February 11, 2009 Report Share Posted February 11, 2009 First of all, pull processor covers and wedge flat head screw drivers in the corver sensors to trick the machine that the covers are there. Watch as the prints go thru to see where they are overlapping. Here are two tricks that will really help you. First, look at the crossovers, do any of them look like they are dancing around. a wiggling and a jiggling, even just a tiny bit?. Second. Grab a flash light and shine it on the rod where the 'C' clip locks it in, on the upper rack section closest to the tank filters (the rod that holds the drive gear for the crossovers, that side). Watch as the rod turns, does the rodt stutter or hesitate at all? If they do, replace the 6 shaft supports (bushings) in the upper section of each rack with this symptom. If your crossovers are dancing around, replace the shaft supports. If they are still dancing arround, check where the shaft supports sit in place, sometimes they wear groves into the crossover and move around too much, causing the crossover drive gear to loose contact with the crossover gears.

EstimuloVisual Posted February 11, 2009 Author Report Share Posted February 11, 2009 Thanks for your help !! I did all indicated before, but the problem still appears... I checked out all processors racks, all crossover racks, all shafts, gears, dryer net and everything it´s OK.... Most rare is yesterday i made more than 250 4x6" prints (the problematic size), no one were overlapped. Today I made about 200 4x6" prints, too many were overlapped.... In fact, after finished all works, i did tests with "paper feed", checking one by one all racks and crossovers, and no one were overlapped!!! It´s make me crazy, ´cause the problem didn´t appears everytime I made 4x6" prints. I´m still looking for the cause of this problem, i hope i find it, when i´ll make it I tell you what cause this. If you know any other way to fix it, please let me note! Thanks a lot again MasterLaser, manager & Eoughphily, EstimuloVisual Quote Link to comment Share on other sites More sharing options...
eoughphily Posted February 11, 2009 Report Share Posted February 11, 2009 When the prints come out overlapped, are they still wet in between prints? If so, then it's deffinately in the processor section. If they are wet between the prints when they come out overlapped, is it a clear wet, a red chemical wet, or undeveloped wet? That kinda helps determin where in the processor its heppening. undeveloped, comes from the developer, red chemical wet would be bleach/fix, just wet and fully developed, PS1, 2, 3, 4. Another thing to check, pull rack number 6. Pull off the side panels and examine the soft tire rollers. Those are those little things that look like french ticklers, round with bumps all over them. For some reason, in rack 6, they tend to swell and cause extra friction, thus causing the occasional overlapping print. Check the edges of those rollers and see if they are basically falling off the end of the roller. Eoughphily Quote Link to comment Share on other sites More sharing options...

EstimuloVisual Posted February 13, 2009 Author Report Share Posted February 13, 2009 Hi Eoughphily !! The problem still... and deffinately is in the stabilizers, not in developer or fix/bleach racks, the prints came wet as water, with no chemicals. The rare thing is this: when you use distrution function, only in one side overlap the prints, i´m clearly? when i set Distributor "NO", the prints came OK, all of them. So, yesterday i tested with 160 prints 4x6" with distrution function activated and the processors covers opened, using paper feed... no one were overlapped...... unbelieve, 15 minutes before y made 4x6" prints from a coustumer and the overlap problem happened.... So, as you said, I´ll check out rack 6 rollers if their sahpe are in good conditions. Thanks again Eoughphily!! EstimuloVisual Quote Link to comment Share on other sites More sharing options...
white06lacrossecxs Posted February 14, 2009 Report Share Posted February 14, 2009 Our 355 did this exact problem. The soft touch tires were swollen on rack 6. Replaced them and the problem went away. Quote Link to comment Share on other sites More sharing options...
Denis Posted February 15, 2009 Report Share Posted February 15, 2009 As a general rule on most mini-labs, check rubber rollers that are on the racks within chemical, They can expand and cause paper slippage(Allowing paper behind to overlap) Hope this helps!

EstimuloVisual Posted February 16, 2009 Author Report Share Posted February 16, 2009 Hi white06lacrossecxs!! Wich rollers did you replace it? Could you tell me exactly wich ones i should replace? Thanks!! EstimuloVisual Quote Link to comment Share on other sites More sharing options...
digitalfotostudio Posted February 17, 2009 Report Share Posted February 17, 2009 hi, I am jason axisa from Malta. I had a problem like yours on the frontie360. Do not let me tell you what i changed!!! rollers, gears, springs, shafts....... cost me a fortune. Then CLIKK , i saw that the top shaft holder bracket of the P2 rack was slightly loose, thus the gears not reaching each other properly and slipping occured. Due to the fact that it was not so constantly slipping only the 10x15 format was overlapping. Incredibly the 11x15 never overlaped. So that is why i am 100% that only that shaft holder is difective ( just a couple of cents to buy!!!!) Sorry for i can not tell you the exect part number cause i sold the 360 and bought the frontier 7100 so i do not have the manual of the 360. If you do not figure out which part i am refering please email me the part index of P2 rack as all racks are the same on top and i can tell you the part number. hope i was helpful and sorry for not answering sooner but i only registered yesterday. regards jason axisa Malta just in case you are still in panic! telephone 00356 21438825 Quote Link to comment Share on other sites More sharing options...
digitalfotostudio Posted February 17, 2009 Report Share Posted February 17, 2009 PS make sure to check after which rack the overlapping is happining(mine was P2) by opening the top and you can temporaly add a little electrical tape on the end of the top shaft to slightly expand the shat circumference. Visually i noticed which rack was giving me trouble by seeing the cross over rollers slipping intermitantly. Quote Link to comment Share on other sites More sharing options...
EstimuloVisual Posted February 17, 2009 Author Report Share Posted February 17, 2009 Thanks for your data Jason. I´ll check out all shaft holder brackets, although I´m still thinking the problem appears because of soft rollers...

digitalfotostudio Posted February 17, 2009 Report Share Posted February 17, 2009 31B7499922 should be the support shaft code number Quote Link to comment Share on other sites More sharing options...
vaidean.radu Posted May 20, 2009 Report Share Posted May 20, 2009 had the same problem. It was because of a crossover rack not clicked in on both sides. Pushed it in and now it;s OK Quote Link to comment Share on other sites More sharing options...
defotoboer Posted May 24, 2009 Report Share Posted May 24, 2009 this problem appears in thedryer !!!! its in the top were it come from the big belt running up there it stucks in te unit you cam pull out.....believe or not this is what you have to do....unscrew this unit (four screws) and place it on a table....now you see the rubber roller and on top yousee white roller with presure springs....you haveto tighten this springs (all of them) or replace thissprings with newones...if you want to tighten them yourself take a coupple of hours to do...remove the spring...cut off the top so you make it shorter about 12 mm then bent a new eye on it and put it back...then thenext..and the next..alsoclean the white roller with alcohol becouse they are sticky and thats not ok....after doing all the springsput the unit back and the problem is solved !!! goodluck Quote Link to comment Share on other sites More sharing options...
hdarmawan Posted January 26, 2011 Report Share Posted January 26, 2011 I'm trying to install new rollers on racks PSx. Which side of the gears on the rack I need to dis-assemble ? The side that's on the chain side or the side that's on the pump ? Thanks for any input. - Harry Quote Link to comment Share on other sites More sharing options...
