Good day, as the title says I have a new problem with this machine and I am starting to think that it was not a good choice, the printer can print 10k without problems, but suddenly it clogs the input from the LCT module and there is no way to to stop jamming, when removing the jam the machine is ready, but it jams in place, if I exchange the LCT input sensor with the registration sensor it starts working without problems for other 10k or 20k, the truth is not I find a solution for you, since I changed the sensors for those of another machine, the jam 027 refers to the LCT relay sensor but in the service manual, nor in the parts manual does any reference appear to what mechanism it is, I welcome any idea, they were always from great help

You must not have the same service manual that I have. Both the RT5070 and RT5080 have their own Replacement and Adjustment sections in the service manual for the Pro 8120.
Now go clean the dust and paper lint off those sensors. -

Item 3 could be the culprit. The wires start to break where they go to the connector at the rear of the drawer unit, usually causes an intermittent problem. Check them closely, sometimes the wires break inside the insulation, they look good on visual check.Last edited by anothertech; 06-11-2020, 03:20 AM.Comment

Re: JAM 027 in ricoh pro 8120s, help!!
pull the tray..
what are the condition of the feed/sep rollers?
look in the body of the LCT with tray removed, do you see any sensors in there?
have you really checked the parts manual for ALL sensors and their locations? ricoh is usually really good about marking them in parts and service manual.
have you run sensor test? does the jam extend past the LCT?
you have to provide more info for us to help you.
what are total page counts on machine?
on PM parts?
are you trained on any ricoh unit?Comment

Thanks for answering, I found it in the detailed description manual, not in the service manual, the first thing I did of course was clean the sensors but it did not work, as I said the only thing that worked was to change places between the relay sensor and the Registration TimingSensor, after this the machine continues printing without problemComment

Thanks for responding, thanks to the previous user who shared a screenshot of the detailed description manual I was able to know what the relay sensor was, anyway I was already pointing to that sensor without knowing its name, I was looking for it in the service manual only.
I did not run a sensor test, but if I have identified the jam to the relay sensor, I already swapped lct modules and the fault returns, when it jams it does it from trays 4, 5 and 6 in the same way, and all the time, the leaves do not go beyond the registration area.
The machine has 3 million pages, the PM parts were all replaced on time with original parts, the pickup rollers are practically new, he is a problematic customer and we are monitoring for weeks on site, I do not have much experience in high-end machines volume but yes in ricoh, models mp and mpc

Has the LCT been removed to check for debris in the feed path? Has the machine been levelled properly?It's 106 miles to Chicago. We've got a full tank of gas, half a pack of cigarettes, it's dark and we're wearing sunglasses.
Hit it.Comment

If the unit runs OK for 10K and then starts to jam over and over again try turning it off for about a half a hour and see if you can get another 10k out of it before it jams again. Don't take anything apart just let it cool down. You may have a motor heating up and then failing at a certain point. I had this happen on a 8110 with less than 400K on it. Drove me nuts because I would start taking everything apart and then back again only to have it run a few thousand and then it would jam up solid.
Good luckComment

If the Pro 8120s has been properly installed in accordance with recomended ambient temperature and humidity overheating should not be a problem.
Temperature Range: 10 C ~ 32 C (50 F ~ 89.6 F)
Humidity Range: 15% ~ 80% RH
Ambient Illumination: Less than 1,500 lux (do not expose to direct sunlight)
Ventilation: 3 times/hr/person
I had a school district print shop with 2 machines and never a heating problem. At first they had a Pro 1357EX and a 1060 with a booklet finisher. QWe found that the 1060 could do 6 to 12 page booklets as fast as the 1357 and free up the 1357 for other work. When doing booklets the 1357 would not start the next booklet until the current one had stapled and was being folded. The 1060 didn't and at roughly half the over length of paper travel could the total time to do 500 booklets was less than 1 minute difference. The next year the 1060 was replaced with a Pro 1107EX with a Plockmatic. 1357 was then replaced with a Pro 8010s and eventually the 1107 with a Pro 8210s. These machines did a total of about 5 to 7 million a year, about half of that during the summer when daily outdoor high temperatures could reach from 97 to 110, occasionally more.Comment

1+ on the possible bad motor, I had a Pro 8100 give me that kind of jamming, every time I thought I had it fixed I had to have the customer run it while I hung around, after a few thousand copies it would start jamming again, turned out to be a bad motor. Some of those motors run really hot all of the time.
Installing the filter mod on the right side of the main frame helps keep the air moving.Comment
