Toshiba 3525AC E190 Non feed jams.

[guirs04]

Hi all,

I am a new tech that works on mostly Kyocera and Toshiba.

I have come across an issue were the customer claims the copier is jamming but there is no jams through the paper paths.

The jam code is e190 so the LCF according to the service manual. The log shows constant E190 jam codes. 6 In the event log on the day i attended site. And even more on the previous days

However, when i am there. I put through hundreds of printouts through lCF with no jams. I cannot get it to fault while im there.
The rollers feed counts are only 60k and theyre fresh and clean with plenty of grip.

They aslo have papercut installed on the machine, I don't know if this could affect it somehow.

When the KD-1073 came out, we noticed a HUGE uptick in E-190 jams. What we found was the same problem and then I figured out what was happening.
At time, for whatever reason, when sitting a machine down on the KD-1073, you may not align it properly, then someone will say I need a better grip, so the
machine gets sit onto the LCF while someone gets a better grip, then sits it down on the LCF. The frame of the 1073 differs from the 1072. It's not quite as
strong. This will cause the frame, to bend inward so that the metal frame slightly will rub against the LCF feed roller, thus causing a jam. Once I noticed that,
and bent the frame back a bit, it corrected the E-190 jams. Now, when we place a machine onto a KD-1073, we make sure NOT to sit it on the LCF unless it aligns
perfectly. I think if they would increase the length of the alignment pins about 1/4 to 1/2 inch it would correct it, but I don't see that happening.
