Kyocera 7052ci jam that won't clear. Exit Feed switch?

[Necrocannibal]

So a tech went to a place and this jam will not clear and Exit Feed is the switch that is on in Sim 31, there is no mention of this switch in the manual and of course they tried the Off/On main power to try and fix it and it has a jam 0000 so we don't even know what jam code it had. Does anyone know where that switch is what it is called in the manual? I do not understand why Kyocera can't keep names of parts the same between the machine and the manual, it very confusing and makes it hard to try and work on things sometimes.

I am assuming that Exit Feed is in or around the eject section area just after the fuser?

Re: Kyocera 7052ci jam that won't clear. Exit Feed switch?

He found it, it was the switch just above the fuser going into the eject section. I am still not sure why Kyocera can not keep the names of parts uniform to cut down on confusion.

Glad you found it

Re: Kyocera 7052ci jam that won't clear. Exit Feed switch?

Kyocera often has at least three names for every switch:

The name in the Disassembly Section
The name in the Simulation Section
The name in the Parts Manual

My theory is that each of these sections is edited or translated by a different group, and these groups do not communicate between each other. So depending on who is translating that day, you may get differing results.

When I search for such things I will find out either the sensor designation (PS21) or signal name (say FES, fuser exit sensor), then search by that. You'll have better success. =^..^=

Thanks! I'm pretty good about researching and finding their second and third names but just couldn't find it but my educated guess was correct.

Thanks! If I were there it would have been no big deal but he's a new tech and wasn't sure.

I've been training the new guy and I've been going deep in the manuals because I want him to know how to find things. There's something definitely lost in translation throughout the manual.


Yesterday we were training on a 3552ci and it was making a noise. It sounded like a fan. I went to sim U037 and turned on ALL fans. It turned on all the fans except for the Main PWB fan....which is the one that I need to turn on. I still haven't figured out how to turn it on.

The fan will turn on for about 10 seconds when you first switch the power on. I tried another fan and the result was the same.

I love the Kyocera devices but damn if some of the Service Mode shortcomings don't drive me crazy!

After reading this thread I decided to try to look up the sensors in the manual and find them on the machine. I'm struggling like big dog. lol

I'll spend some time this weekend. My homework assignment, I guess.

I assume, based on your original post that 57 and 59 (highlighted on attached doc) were the sensors in question. I am looking at the 7052ci Service Manual Rev. 2, in Section 3-4 under Sensors and Switches. It will give a decent breakdown on the general location of all the sensors

Re: Kyocera 7052ci jam that won't clear. Exit Feed switch?

I continue my journey to trace down all the sensors in a 3551ci (this is the model I'm training new guy on). I'm gonna keep this short and to the point - it's harder than it needs to be. Now that that's out of the way....


In sim. U031 it shows a total of 17 sensors that can be toggled on/off. On the machine that we're training on, it has no finisher thus no bridge unit, thus we can ignore those sensors. The bridge unit has 3 (maybe 4?) sensors, so that leaves me with 14 sensors to trace down. Thus far, I've done 6.


- DU2: located above bypass tray - Duplex sensor. (open door)

- Feed 2 (feed B): Paper enters conveying unit @ Tray 2. Note: has sensor arm.

- Feed 1 (Mid): Paper enters conveying unit @ Tray 1. Note: PT sensor, no actuator arm.

-Regist: located immediately below registration roller. Note: No actuator arm. PT sensor

- Fuser Feed: located on the fuser after paper passes between heat rollers. Note: Has actuator arm.

-Exit: located in exit tray section. Has actuator arm.

The rest of the sensors will be harder to manually toggle but I'm give an attempt.

Re: Kyocera 7052ci jam that won't clear. Exit Feed switch?

I traced down another couple of sensors.

Cassette 1 Feed: located on P.F. Unit 1. This sensor has no actuator arm and is located directly after the primary feed tire. It has no actuator arm.


Notes: The easiest way to toggle this switch for testing (toggle) is to unplug the wiring harness @ Tray 1.

The feed head has a total of 3 sensors. (The other 2 sensors don't show up on U031...they are paper present sensors.) Only sensors that result in a jam condition show on U031.

Cassette 2 Feed: Same as above but on Tray 2 feed head.

Re: Kyocera 7052ci jam that won't clear. Exit Feed switch?

Man, it's a lot of damn working tracing down all of these sensors.


I'm trying to locate the Belt Jam sensor. The best I can tell is that it's not used in this model.


In the manual it lists the sensor but shows no supply voltage (left blank) and in the description it says "Not Used". On to the next one.


Edit: That's 9 of 14.

10 of 14


Exit Feed : AKA: Switchback Sensor


This sensor is located in the 'eject unit'....which comes with the finisher. Which has a switchback unit that routes the paper either (a) in the finisher or (b) on top of the finisher. In any event, my machine doesn't have a finisher. On to the next one.

Re: Kyocera 7052ci jam that won't clear. Exit Feed switch?

I'm taking a couple hour break on tracing sensors but a quick note:


I think a tech will be much better off tracing the sensors in a known good machine and making notes rather than having to rely on the service/parts manual when you're out on a service call. Just saying.


PS - Should I be taking pictures of all the sensors to go along with my notes? blackcat would have pictures. I think I'll add pictures. lol
