Good evening everyone. Been to a double recall today to sort out a skewing problem. Had already checked out this forum before attending. Found various possible causes. Very good! The 2 previous engineers had failed to resolve the issue and one of them had "played" with the laser adjustment plate without marking the original position! Anyhoo, I checked out the side door tension rollers on the top door, everything ok there! Checked the registration roller springs and again they were ok. Checked the final set of relay rollers, the ones on the inside part of the bypass assembly. There are 2 sets of 2 tensioned rollers and I noticed that the tension of the 2 sets of springs were very noticeably different, one set weaker than the other. Hmmmmm! this machine has only 100k on it! So I stripped them out and "re tensioned" the 2 weaker springs, refitted and tested. Problem solved!! Machine was off like a dirty shirt, true as an arrow, zero skew from any tray!! I am no expert on Kyocera machines but have had no end of problems with these variants, dev units, drums, charge rollers and fusers failing prematurely , and yes we use original toners before that chestnut rears it's ugly head. So then I gets me laptop out to order 4 new springs only to find that the part numbers for them are different!!! What the hell is going on! Call me picky but the door relay rollers are evenly tensioned for the obvious reason of feeding paper straight and the reg roller is evenly tensioned, again for the same obvious reason. so why would the final relay roller idle rollers be tensioned unevenly front to rear???? Who designed this abomination? Hmmm! Let's make the paper come out of the trays straight then just before the reg rollers we will skew it against the final relay rollers and then miraculously hope that the reg rollers will level it up again!!! Ha- Ha!! Never gonna happen! Got back to the office and checked out some new ones in the showroom and guess what, they are all the same. They all have a skew on them of around 1.5 to 2.0mm. Don't know what the acceptable tolerance is, don't really care! So beware, if you want a machine that doesn't skew
