ricoh 2015 jamming in fuser

[ash_572]

customer is printing heavy blackwhite ie full a4 pictures. papers wraps around the hot roller in the fuser. have not replaced any parts yet dont really know the history of the machine. machine has done 200k. normal printing is fine like meter reading and letters and stuff.##

customers says they have done these types of prints many times before.

Sir,good day!the problem is the printing,the machine required to print must have a distance of 5mm of leading edge.but now is already jam around the hot roller please check the stripper pawl and spring if its ok.if not ok please repair it,and next time please advice or explain to the customer if they copy a full image into a A4 size of paper must have a 5mm distance of leading edge between the image because it cause jamming.goodluck ang have a nice day.

but why isit jamming now and not before then? stripper fingers and springs are ok.

Gosh that sounds a lot like a customer question.

Answer: Probably because the hot roller is worn enough now that it is not as "slick" as it was. So pages want to stick to it more now.

You can either replace the hot roller more often, so that copier always has a nice "slick" new one in it. Or you can adjust the lead edge void enough so that it isn't trying to wrap when the hot roller gets older.

(P.S. I forget if the fuser PM is 60k or 120k. But if it has actually gone 200k with the customer doing this kind of prints (doubtful), then the hot roller likely trashed anyway.)

I use the stripper pawl springs from the Aficio 2045 fuser. These springs don't come off easy. I find the existing springs too sensitive.

the hot roller, pressure roller, fingers and springs are important and if doing full coverage (or near enough) wont go over there expected life by much.
Gernah is right about ensuring a large gap of 5mm or so is kept so the rollers can grip the paper. You can see if setting up to feed A4 r helps but of course means the central part of the rollers will wear down at a quicker rate.
Also once the Hot rollers have lost the outer coating though wear or often due to an engineer "cleaning the roller" its performance will be far worse yet from a glance look fine.

The life of the HR is 60 k while the other bits are 120k. But i have found if they normally do low coverage printing then the HR will often get to 120k.

One bit thats important to check and replace is the pressure roller bearings as they get worn down i find you get problems with jamming. Even if all the other pm parts are replaced, many Engineers dont tend to bother changing i have noticed.

Dont forget to make sure you have the latest firmware loaded on as it ensures if it does jams it should stop quicker so the customer can remove with less hassle.

Also when you say the finger pickers and springs are ok how are you saying they are? Often they will be fine when low coverage copies are made.

Dont forget to check the paper with it being damper now the summer over and the parts that bit much older this maybe part of the cause.

Often a problem i havbe found is due to a whole mix of things rather than just one single issue.

slick!

Sir,are you sure that the print image before is the same as the printing now?maybe before the distance of there image is defferent.but as what as you mention the total copy now is 200t already its better you change all the pm parts of fuser unit so that make it sure that yuor problem its solve.this kind problem its a simple only but you must focus to solve this ok goodluck and god bless.
