I had been working on the transfer unit fuse, which is accessible by opening the bypass tray. I needed to get a new fuse, so I closed the tray (lifted it up and latched it in the closed position). I came back with the new fuse and found that, although I pull up on the lever to the left of the bp tray, the tray is stuck on the right side and will not open.

What latch or hook is used to keep the right side in place? How iis it accessible? I could use a diagram of the internals of the tray latch mechanism if anyone might has that.

Any help is appreciated. Thanks!

if youve closed the right side door with the transfer belt unscrewed your in big trouble.

you may be able to move the belt back into position to allow the door to open if you remove all the imaging units and waste toner box and maneuver it from there.

No, thankfully, I had replaced the transfer unit screws, so as not to lose them or forget where they belong ! That said, is the remainder of your suggestion still the only way around the problem?
thanks!

Ummmm, if the locks are screwed in and the belts not installed it may not be able to go in enough to let the rear door claw clear the transfer belt handle.

Good luck my friend.

Worst case scenario uf u cant get the belt to budge you will have to break and replace the complete rhs door unless you can find another way of releasing the hook without destroying it.

Hi! Can't remember the model, perhaps it was a C351, probably a C250 but the scenario was the same of yours..You have to pull, the door, probably the plastic hooks are in a stuck position. Dont mind, is very difficult to break something . Good luck! :)16093

Thanks for your reply. I don't have much continuity in the time I can work on this issue. I appreciate your thought that "it is very difficult to break something", cause I can't get this door to budge. The left side has the lever pull to unlatch it, but it is stuck on the right side. I can pull on it from the top, but it appears there is something holding it. See the attached photo where there is distortion on the side (red circle) when I pull on the top of the door.

I am a bit timid about really jerking it, but it would seem there should be some access to free whatever "plastic hook" might have caught. I can poke a screw driver in there and move a couple of white plastic things, but it doesn't really free the sticking.

Is it possible to remove the large block shaped cover to gain access? I have pulled the screws from top and bottom (one circled in blue) and it is quite loose, but there seems to be something keeping it from coming off. I am curious that with the cover off I might find access to the clip or fastener that is catching the door.

Thanks for your help.

you are going to have to remove the covers on each side of the RHS Door.
this will make it easier to gain access to the latches.
What you have to do is gain enough room to slip a long thin screwdriver in there and move the latch down.
one of my previous techs did this on the same model machine.
its going to take some time and patience, but it is possible to do.

Anybody in the Denver Area that would be able to come take a look at this? I feel that if I knew where to find the latch / hook then I might be able to get to it. It's pretty much disassembled at this point and I don't know anything more than I did before I took it apart.

This would be billable time. My contract w KM is long expired. Please call 303-588-7219 if you can come over.

Thanks,
Ross

Happened to me once - had to force it to open, pull as hard as I could. Luckily it opened without breaking anything, although I was already counting on replacing at least the door claws, if not the entire door itself.

Most probably the tech will have to do the same and, if anything breaks, bill it anyway because you caused the entire problem. Good luck!

after all this, I think you will find the total cost of the exercise is going to be far greater than the cost of a new transfer belt.

the right side door here retails for about $200, bare that in mind before letting the tech spend hours and hours trying to free the door, if its getting to 45min mark just get them to break the door and replace it. (get a quote on the door assembly first, it may be so cheap there that its not even worth the effort)

1 hour should be more than sufficient to change the door, though I've done a few before due to the suction fan becoming noisy.

make sure the duplex unit is removed safely before destroying the door.

Thanks all. I guess I need to pull out the long bladed nail puller.. Hah!

Thanks to all for your responses.

I finally pulled out my carpenters pry-bar - about 1.25" wide and a foot long. This gave me the leverage to get the door open again. The right and catch had been bent forward during opening the door, but was likely put slightly out of position when removing the Transfer Unit Belt the first time. That slight position displacement was enough to keep the right hand latch from releasing. I couldn't see it in the manual or the exploded diagram of the door - I have pics if anyone is interested.

I had to remove the fuser to gain access to the catch and bend it back into position. All that is corrected now. I replaced the fuser and all the rest of the assemblies I had worked with to gain access to that latch - and narry a single screw left over :-)

So I powered it up, plugged in the lan cable, and boom! Here came the documents in queue - from some two months back or whenever I started this thread!

BUT!!! - The output is verrrrrrrrry faint (although well fused - no smudges), and the display indicates:
"Machine Status 27/ / / / /"

The manual I purchased from JustManuals.com offered earlier in this thread tells me "P-27 - 2nd Image Transfer ATVC Failure. An abnormal average value is detected during an adjustment to the second image transfer ATVC value."

I haven't a clue what to check next to resolve this issue. Any ideas?

Thanks again!
Ross

If the machine didn't have that problem before, then most likely the door isn't closing properly or there's some kind of problem with the door contacts.

The 2nd transfer is done with the black "sponge" roller on the door - check for any bent contacts. Try to take a couple of prints while pushing the door with your hand to see if it helps - if it does, then the door isn't properly closed.

Had this happen at training school. Someone locked the door up, without putting the transfer belt screws in. Then ensued an hour or two of hilarity as students & instructor proceeded to remove the door. It's amazing how much six different people with six different ideas can "stuff up" a brand new copier.
