Sharp AR-M237 Repeated misfeeds at side cover, right out of feed tray

[blacksunshine]

Sharp AR-M237 Repeated misfeeds at side cover, right out of feed tray, sometimes it will pop the side cover out, sometimes not....sometimes it works just fine sometimes not....only problem with this machine is this little issue...

Any suggestions?

TIA

if the side door is popping out then the tabs that hold the latch in are broken, and the door needs to be replaced. if the door isnt keeping the switch activated it will stop the paper where ever it is at at that time. just like if u opened the front door after u hit the copy button.

are u reffing to the bottom side door that slides out or the upper one that hinges down, guess i shoulda ask this first

Are you talking about the manual feed tray ? (Hand Feed tray)

[blacksunshine]

it's the actual slide out tray that you pull out to get misfeeds out...the manual feed is part of that but it is not having any issues....

it's that actual 'drawer' I guess you could call it, you have to depress pull to pull it out....it is almost like a hook is not hooking good enough then when a piece of paper comes through, it will sometimes kick that out just a tad and boom, error....not really a jam I guess you could say but since it stops there and the drawer pops out a bit, it's all the same in the end....

if you press in on that drawer, it has not done this...heck, if you could take a screw and just screw the door to the housing just in the little gap, it would probably solve the issue till you had a real paper jam....

Just getting my head around that model machine. I think that machine is similar to ARM-207.
The ARM-207 has two electrodes(coil springs) that connect from the side door assembly into the main area of the machine. The home position for these electrodes(coil springs) is around the rear of the fuser section when the door is closed.
Just check one or both of these electrode springs are not bent out of position. If they are this will prevent the side door assembly from closing. This will cause the side door to pop open by itself.

There is also two electrode lever type springs in the side door assembly that you can check as well.
Check one of these are not bend out of position.

everything looks fine...only thing I can think is maybe that large spring on the left side of the drawer is a bit too stiff maybe...it has a long tail that looks to go to the other side of the drawer...like a long wire with a spring end.....I was going to pull that spring off thinking it was just a plunger type spring and see if the problem existed since this spring will help in popping the tray out with little resistance from the inside....no go since it tails off through the other side of the drawer....it's almost like a clutch jam type spring...but probably has nothing to do with anything

I have to agree with Silvertoast. I thinks it's the plastic features on the door that keep the door shut, and get worn down. It could also be the top cover of the bypass tray assembly. There are two plastic features that hook on the door. One or both. =^..^=

have to look at the arms tomorrow to see if there is any 'modification' that can be done to make this 'cooperate' more....I have two that do this and hate to see them meet their demise just because of this....but they are pretty much on the way out anyway...new contract was signed today....

turns out the issue seems to have been a couple green lockdown arms that were not locking down on the fuser I think it is...there were a couple tabbed plastic pieces that are in there that were broken.....now the fuser is locked down and seems to be working fine!

Those "fulcrums" as sharp calls them broke all the time. Sharp made a new style that didn't break as much. Pretty common for one to break. Never saw both broken at the same time but that might explain your jamming since the fuser would have no preasure.

one unit had both broken and the other only one was broken......here's for CHEAP fixes!~

These machines will all eventually need the feeding frame replaced (above the fuser)- heat warps the plastic and bakes it till it shatters like peanut brittle. Newest frame part number is CFRM-0038RS69 (around $150). Any black pieces of plastic dropping from above the fuser is a warning that shouldn't be ignored. We have reduced the fuser temp from 190 to 165 for plain paper - the M257/317's have extra exhaust fans in there to help vent the heat. These are not like M207's which are junk IMO, much better boxes.
