Question about Konica Minolta magicolor 2300DL Laser Printer
When printing, the first page gets folded twice, horizontally. Quite nicely, but useless for work. The rest of the pages print normally. How can I correct this? There are no error messages other than paper jam from the first (folded) paper. Have checked inside the machine and all the rollers roll, nothing seems excessively worn; there are no bits of flotsam blocking things.
I kept digging until I found some helpful, lucky people that stumbled across a solution. The cost of doing the repair yourself is about $1 for superglue.
I detailed the repair in my blog: http://dlburkhart.spaces.live.com/blog/cns!5BA5F950B86A8BE5!182.entry.
I don't know if that URL will work as a permanent link. So, just in case, the same information is on my business web site on the Tech Tips page: http://www.BurkhartTech.com/Tips.html.
I hope to have helped.
If anyone can use a custom web site, I can really use the work. I left work a couple of years ago to be a stay-at-home dad and to try to start up a web site business. Things started out okay. But the economy soured, all of my business dried up, and now I can't find full time employment.

I tried solution 2 on my 2300DL that was also folding the paper. For a while It was only doing it on the first sheet but today it started doing it on every sheet. My daughter was trying to print out an assignment and we didn't manage to get it to print without the folds even though we tried several times.
Even though solution #2 was for a 2200 I thought I would give it a try. There were sure lots of screws involved and I took off most of the left mother board connections as well so I could get it out of the way. Also I removed the left side panel. It was small and only required me to remove two extra screws. Removing this side panel gave me that little extra room I needed to operate. I then unscrewed the plate behind the motherboard and there was a solenoid there so I removed it and checked it out. The little felt pad discussed in the solution was intact but I noticed that it had compressed a little over time. The only reason I could tell is that it overhung the place where it impacted slightly so that part was still the original thickness.
I ended up cutting a small piece of duct tape to exactly the same size using an x-acto knife and then stuck it right on top of the felt. I then reassembled everything.
The first page came out even worse but it is now printing perfectly again. I'm thinking the solenoid may of had to adjust on the first page as it sticks in the gear assembly. I only just fixed it tonight so I can't say how it will perform over time but I couldn't get a single page to print earlier without the folding and now it is printing perfect so I'm optimistic.

I have a magicolor 2300DL that was experiencing this problem and solved it today. I replaced the Transport Unit. It cost $85.36 plus freight plus tax, just short of $100 for delivery to my Northern CA location. This suggestion was made by Konica Minolta. I had them email me the service manual to save the labor cost. It took me 10 hours total. The disassembly procedures are on pages 96-97, 100-102 and 108-109. I found them to be misleading and some corrections were needed to page 97. No. 1 required removing 3 screws, No. 2 required removing 4 screws (2 large in the rear and 2 small near the front), No. 6 required removing 6 screws and No. 9 required required removing 6 screws because 3 were previously removed by No. 1. No. 9 required removing the Drum Cartridge to get to one of these 6 screws. Do not touch or allow bright light to contact the green surface of the Drum Cartridge. On page 109, I added step 10A, Remove the left side cover (3 screws). There are 4 plastic clips also holding this cover on, so be careful not to snap them off when pulling the panel off. This step was necessary to allow 3 screws to be reached in Step 11. In Step 11, the diagram is misleading. There are 2 long screws holding a fan. Mark the orientation of this fan. The fan wires lace through a plastic clip. You must thread the two circuit board connectors through this Controller Box and 2 screws to the Master Board (PWB-A) go into this Controller Box. The Transport Unit has 2 connectors, a white one that goes to PJ12 and a blue one that goes to PJ13. Getting the Master Board connectors labeled and out of the way was the most time consuming part of the project. I added steps 13A, Remove Right-side door cover and step 13B, Remove Right-side rear cover to give additional lateral spacing to remove and replace the transport unit. Step 14 is misleading as there are way more than 10 screws involved in freeing the Transport Unit. There are actually just 4 each on the front and rear, 2 long brass ones and 2 short silver ones on each side. The diagram on the rear shows 5 screws, but there is only 4. The top one in the diagram is not there. The front side is more complicated. There are 2 clips with screws that must be removed, plus 1 screw for a bracket which hides one of the 4 main screws to the Transport Unit. To get this bracket off, requires loosening two large screws on the Drum Cartridge holder (black plastic), then sliding it out far enough to unclasp the bracket. The right side door is connected to the Transport Unit by a strap. So, add one more step 14A, Transfer the nut to this strap screw from the old Transport Unit to the new one. This nut will probably be missing from the new Transport Unit. Reverse the disassembly order to put everything back together. Test it and you will have saved a bunch of money in labor cost.

I took my entire 2300DL apart, took out the drum (be sure not to touch the green roller and put the drum in a dark place!). Then I blew the entire printer out with air. There was a ton of toner inside the printer so I used a small toothbrush and cleaned all the cogs and wheels I could see with the toothbrush, blew them all off again and used a VERY TINY AMOUNT of sewing machine oil on the wheels and the moving parts where they rub plastic to plastic, put it all back together. The very first print folded with the single fold, the next one did the accordion thing, But all prints after that have printed perfectly.

This is an update to DLBurkhart's link.
A correction to what SL4 does, Its the Belt cleaner Separation solenoid, not Transport Roller Solenoid.
Heres the list as follows.
SL1 Manual Feed Paper Take-Up Solenoid
SL2 Transport Solenoid
SL3 Synchronizing Roller Solenoid
SL4 Belt Cleaner Separation Solenoid
SL5 Second Image Transfer Roller Pressure Contact Solenoid
SL6 Fusing paper Loop Solenoid
Those are straight out of the Service Manual
Hopefully the size is readable. Otherwise the Service manual is readily available online. Refer to pages 38,39

Many cheap papers are only finished on one side. The **** will often have an arrow on which way to place in unit. If not try fliping paper over, and try. Next try reversing the paper in the feed tray. Laser paper is produce with zero to very little dust, as compared to ink jet or typing paper. a good 20#, or 60#offset (24#) with often help also. Humidity can also penetrate the top sheet by being absorbed into the paper, and causing irregularities. Finally some lasers, and copiers drive systems work better with a rougher finished paper, as apposed to a slick paper that drive tires slip on.

I have a KONICAL MINOLTA 2300DL, i have found a simple FIX:
Unscrew the BACK of the printer and find the Main Engine & the white Rolling Bearings.
Just Spray generously some lubricant or grease on it.
Put back the cover,
The printer no longer make paper Jam neither Paper FOLD

I have the Same problem with the same model. I have not had time to dig into this on the QMS, but usually as far as my experience with HP and other laser printers it usually turns out to be and electronics failure. These printers rely heavily on timing and when one of the many feed stages fail a page can hit a roller that has not be given the ok to feed. This causes the page to pause while the other roller continues to push. This jam up folds over on itself thus causing almost perfect folds. The out of sync feed roller then decides to feed after the fact and wahla. Magic origami. With Hp we used to replace a feed assembly and you be back in business. These thing are quite complex and probably cheaper to replace than to fix. However I dont like to lose battles like this so I will eventually post what I find for you.
