Taskalfa 8001i JAM 0000 02,03,10,15,19.

[Suppotech]

Hi Guys,


The machine was displaying this Jam code. JAM 0000 02,03,10,15,19.

I have thoroughly checked and cleaned the paper path and sensors. The fuser unit was pulled out for inspection and the gears and leaf dust cleaned.
I also checked and cleaned the paper exit flags and sensors. I have disconnected and reconnected all the connectors on the boards.


Turn on the machine, and the jam icon is still there.




Any suggestion/tips would be greatly appreciated.

hi

i changed the sensor but still the same problem .
lot of many jam

in the service mode U031 the sensor are blocked.

That seems like an abnormal amount of sensors that are in the "on" state. I always try to manually toggle each sensor to make sure they are working correctly. Of course, you'll have to locate the individual sensors. Maybe someone has an easier way but that's my method.

I just checked the sensors (U031) on a 3552ci (without finisher) and none of the sensors are activated. There's something going on with your machine to have that many sensors lit up blue. You need to check them all.

I changed three sensors but still the same jam...in U031

What 3 sensors did you change? You should have tried (my opinion) to manually toggle the sensors before you changed them. You have +5v supply, ground and the signal wire. I'd start by checking the +5v and ground.


PS - It's very rare you'd have more than 1 sensor go bad at the same time, IMHO.

Same here. For sensors on the door assembly you'll have to close the door to get valid readings (the door sensors are connected through a modular connector), so you'll need to strategically place paper in front of these sensors and close the door to check HI/LO state. You can buy a test pigtail, to connect the door electronics to the main body with the door open, but I've never actually seen one. If you have a corpse lying around with good connectors, you can make your own test-pigtail.

When I was first learning the particulars of the 3551ci, I made it a point to find each sensor location. I think I used a combination of the service and parts manual. Then I set out to manually toggle each one. I think I got some help from you. Can't be sure as you've helped me with so many things.


BTW: What are you thoughts on all the sensors being on in his picture?

BY the way, what I did for the sensors in the door is insert a piece of paper to activate the desired switch and just close the door. It worked nicely.

I would suspect either a missing voltage from the LV power supply or a defective PF PWB.

Quite a few sensor signals pass through the paper feed PWB, and if it was malfunctioning you could lose a whole group of sensors at once. In the same way, many of the sensors are powered by the same 5vdc supply voltage. If you lost that voltage, you could lose a group of sensors all at once.

It's also possible that the main PWB took a hit (lightening or power surge). =^..^=

All of those were possibilities in my mind. In any event, he now has a road map. Hopefully he can pinpoint the problem.

hi and thx you for your support

the sensors that I changed


exit-sensor
sensor register
and bridge sensor
but it didn't change anything

+5V and Gnd are tested .

What 3 sensors did you change? You should have tried (my opinion) to manually toggle the sensors before you changed them. You have +5v supply, ground and the signal wire. I'd start by checking the +5v and ground.

What is the wall voltage that you have this machine plugged into? I ran into something similar a few years back. The client took the 20 amp surge and bent the prong so it would fit their 15 amp wall outlet, the machine would have weird jamming issues because the machine was not getting the proper voltage.
