[Jamming] Samsung CLP-315 jam 1 only when I print non-color document.

[Guest]

Hi all,

I've used 4 years well with CLP-315 with hardware reset chip installed (removed EEPROM chip)
I don't think the reset chip is related to the reason for this jam.

Recently I got "Paper Jam 1" error message.
I searched and found most reason is defective exit sensor on the left top of the fuser.
I bought the NEW sensor and replaced yesterday but still the same jam error.

Very strange thing is
printing color character is no problem.
Paper jam happens only if print document without color character.

Pressing 2 seconds button --> prints 1 color demo page. No problem.
6 seconds --> should print 1 configuration page,
but it print 1 config page and 1 blank page, then LEDs flashing all
and print 1 config page, then 1 blank page is coming but jammed when the exit sensor's plastic bar start to raise.

The same thing happen when I test with Word document file.
Yellow 1 dot file --> print 1 page well.
Black 1 dot (or even just 1 space character) file --> print 1 + 1 blank then LED flashing, print 1 + 1 blank jammed.

Anybody has seen this kind of thing?
Power supply weak?
Why color pages are all good? Not mechanical/Electrical problem? Firmware got crazy?

Edit: I just recall the color printing is slow and b&w printing is faster. maybe that's the only difference for mechanical thing. and need more electric amp?

I'm just thinking out loud here:

I agree. As long as you're not getting toner related messages, the chip is unrelated.

Recently I got "Paper Jam 1" error message.

Are you sure you changed the correct sensor? There are a large number of threads on this topic, examining this problem to death.

Why does it only jam black & white? There are a couple of things that caught my attention while you were going on. The blank page can indicate a few things. First it could mean that the paper tray multiple fed, which does throw off jam timing. If the pickup solenoid is sticking, the pickup clutch will cycle twice or more butting a second page up to the trail of the first, again throwing off jam timing. The problem usually found with the pickup solenoid is a foam sound damping pad that gets sticky, preventing the solenoid from returning instantly. The fix is to remove the sound damping foam and adhesive, then replace it with a piece of self adhesive mylar about the same size. A common mistake is to remove the pad and not replace it. if the metal solenoid lever is allowed to touch the core it will magnetize, acting just like that sticky foam.

Why B&W but not color? Perhaps the additional spooling time of the print jobs gives the solenoid a little extra time to return?

Edit: I just recall the color printing is slow and b&w printing is faster. maybe that's the only difference for mechanical thing. and need more electric amp?

This machine doesn't draw very much energy ... 6 amps at most. Your electrical circuit would have to be severely overloaded to make a difference. I would not expect a power quality issue.

Does any of that help? =^..^=

Wow, thank you very much!!

Yes, it is #0604-001393 Samsung Photo- Interrupter at the photo location.
I just finished, power supply re-soldering all points again and got the same jam.

6 seconds' configuration page(only b&w characters)
I tested with only 1 paper in the tray. --> 1 page printed and no more paper error. seems good.
2 papers in tray, holding 2nd paper with my fingers --> 1 page printed and try to pickup 2nd paper, I hold it, then. printer think all good.
2 seconds color demo page, printer did not try to pickup 2nd paper. all good.

B&W and color printing's paper pickup is different. color printing has one step pause when it pickup the paper.
now I confirmed it is pick up mechanical problem like you said, no power supply, no main board, no sensors.
I wish I asked here before buy the sensor, it costs me $20 include shipping.

Now I have to find where the pickup solenoid is, somewhere around pickup roller?

Re: Samsung CLP-315 jam 1 only when I print non-color document.

Find the pickup roller > follow the shaft to the sector gear on the opposite side of the frame > the solenoid will ride against the sector gear. I don't know if it appears in this cutaway ...

Sensor Location.JPG

Nope. But it will be somewhere in the viscinity of the red arrow along one of the side frames. =^..^=

Re: Samsung CLP-315 jam 1 only when I print non-color document.

Yup. Surely enough, that's it. If you do decide to order the new item (and it's probably not necessary), I'd still scrape off the foam sound damping pad and replace it with self-adhesive mylar. Based on the view, I suspect that it will be clearly visible once you've removed the HVT. Be sure to remove all the supplies first. The HVT contact springs will be very difficult to re-install if the supplies are still inside, and toner will dump all over the place, and create a huge mess.

Have you considered a job as a printer tech? You're doing a lot of things right:
Good observation skills.
Reading the forum posts.
Tried a few logical things to fix it first.
Honestly described what you saw, what you did.
Reading the manuals.

Life would be a lot easier if all the threads read like this one.

Thanks!!!!!!!!!!!! You fixed!!!!!
As the pictures, the solenoid is just under the main board. I did not remove any toners or HVT, but all good.
As you said, the sponge pad became thin (thickness from 1.5mm to 0.5mm now)
and the metal plate is almost contacting the solenoid which is magnetized a little bit even without electric current.
so when I push the metal to the solenoid, it stick for 1 second and detached, this means the pickup timing problem.
I could not find mylar things, so I just overwrap 1 layer of the black electric tape.
then tested 6 seconds page.
Hurray~ Only 1 page configuration paper came out!!!!

I just sent a cancellation email for pickup an used CLP315. No need anymore

About 10 days, I opened my printer case 10+ times finally got helped from you.
It's impossible to even imagine opening the main board and find the solenoid for sticky or not.
so you fixed. not me.

I like to fix things, many appliances and cars and house small problems.

As the attched picture, the solenoid is just under the main controller board.
I did not remove any toners or HVT which is on the different side of the printer.

(thickness from 1.5mm to 0.5mm now)
and the metal plate is almost contacting the solenoid's metal which is
magnetized a little bit even without the electric current.

in my case, picking up second paper, then try to print again
and finally give up and paper jam 1.

I could not find mylar things, so I just overwrap 1 layer of the black electric tape.
then confirmed it did not stick at all.

then I tested 6 seconds button page.

Re: Samsung CLP-315 jam 1 only when I print non-color document.

I want to add to this thread as I had what I now believe to be exactly the same problem. My CLP-315W printer would print any page I sent to it, but instead of stopping there, it would immediately afterwards push out one blank piece of paper, then a second copy of the document I had printed and finally it would jam, with a blank piece of paper stuck between the rollers. Reading the many threads and internet anecdotal data about the need to replace the exit sensor, I did that and it did not fix the problem. Then I came upon this thread and the original poster's printer seemed to have symptoms very close to mine. So I checked his theory by printing a colour document (something I never do in daily life) and, like him, I found that it printed without problems. I then took the beast apart, following the instructions and referencing the service manual, which can be found online. It was the deepest I had even been into a printer and I was nervous that I would break something, but it all came apart okay and I took the solenoid out. It is spring-loaded and, like the original poster, I noticed that there was a delay in releasing the spring-loaded piece of metal that the solenoid acts upon.

However I do not believe that the problem was, as the original poster seemed to think, that this piece of metal had become magnetised. As far as I could judge the surface of the "sound deadening" pad that is stuck to the surface had become sticky over time so that it would not release for a second or so - just long enough, I guess, to set another piece of paper rolling through the machinery. Like the original poster, I simply covered it with a piece of electrical tape (having used a cotton bud with some alcohol to clean the surface first) and so far it appears to be working fine. If it fails again in the same way, I will replace the solenoid with a new one since I found them online for about $10. But for now, so far so good. If I had any tips to give anyone attempting to perform the same repair, they would be:

1) Take your time.
2) Do this somewhere well-lit. My vision is not great and I could not see well enough to have much confidence in what I was doing until I took the whole thing out in the yard and daylight came to my aid.
3) Don't force anything; use patience.
4) Be very careful to remember exactly how it came apart so that it goes back together the same way. Taking photos along the way would be a good idea. Use a magic marker/sharpy to mark which screws go in which holes.
5) When you get to the main circuit board, you do not need to remove it completely; I simply detached the wire connectors plugged into its lower edge and then duck-taped the circuit board to the top of the printer, leaving all the wires attached to its top half in place.

Good luck. Hope this helps someone. I am fond of the printer and I would like to keep it going.
