Frequent problem with Ecosys P2040dn/M2040dn

[lebo]

Hello, almost each Ecosys P2040dn and M2040DN that I sold has a problem with fuser (FK-1150).
The fusers after print cca 30-50 K pages starts to turn different speed which causes staining or jams. What are your experiences ?

I need to resolve the problem another way than by replacing the fuser. For example One P2040DN (total counter 80K) has already third fuser kit. One I replaced during warranty and second a few days ago. In addition Kyocera sells FK-1150 more expensive than new printer(?)! So I must to disassembly new printers for parts.
By the way, is it true these models are made in cooperation with Ricoh ?

Thank you.
Bye

We managed to pester Kyocera into extending the warranty of the fuser to 5 years for this problem.
So complain to your Kyocera rep about this problem as this is a known problem with these fusers.
They caused it, they should fix it.

How long are the fusers on before there in energy saver mode. Should be as low as the customer will let you 15min ES and 30 to shut off

We have a ton of P2040dw printers in the field and they all have the same issues. I noticed that after a firmware update, the max sleep mode went from 240 to 120, so they must have done that to help with this issue. It still doesn't fix the issue, just allows the fuser to go a little longer I guess. Why can't they just use a roller instead of a belt?

I don't believe re-engineering the fuser mechanics is one of our options as field technicians. How about focusing on plausible options like reducing the sleep timer? =^..^=

What do you set your sleep timers to? Does it help with the issue?

Re: Frequent problem with Ecosys P2040dn/M2040dn

Yes it does help. The sleep timer is the amount of time until the fuser temperature lowers. Plastic construction fusers tend to fail quickly if kept at high temperature for a long time.

The few seconds of first copy speed just doesn't justify having that fuser hot all the time.

So simple but yet genius. Solid thinking, my man.

Would a 30 minute sleep timer be enough to achieve the benefits of a longer fuser life? I'm about to push these changes to a large group of these and want to know what's working for everyone else.

Sounds like your problem is severe and it's costing you a ton of money. If it were me (and it's not) I would set the timer so that the fuser remained off for as long as possible and the customer would just have to wait a few seconds longer. Beats the the hell out of you being out there replacing a fuser unit all the time.

The shorter the time the better. On machines at home and in the office I set 5 minutes. It's about what the end-user will accept. =^..^=

My same sized Brother MFPs are set to 1 minute before go to sleep mode(by default). Same type teflon sleeve fuser I guess. They do last around 200k under that circumstances. Even on bigger A3 machines common sleep timer is 15min.

Don`t forget to take a look for Bulletin 2S0-0030 (J114)
Item #17:

The oil applied to the fuser sliding sheet might decrease after fuser overshoot repeatedly when the main unit is stopped at jam/service call error, and the fuser torque might increase to cause the fuser jam. (Measure when completing print) ・Aging time is changed by print volume (Max 20s) 　1-4 sheets: 0s 　5-29 sheets: 5s *1　　30-49sheets: 10s *1　　 50 sheets and more: 20s *1: Until the fuser belt temperature becomes 140 degrees C after a certain time (Max 20s)　 ・Heater is turned off during the above aging ・If the next job comes in during aging, it is executed and after completing it, aging is reset based on the specification (Measure when the error is detected) ・The in-machine cooling fan is driven for 60s after detecting jam/servicecall error and stopped at the temperature of 180 degree C or less. New Fk unit together with FW upgrade will solve your problem. Also you can ask KDC for special warranty in case of broken FK-1150.

According to kyo tech, the latest firmware reduces the rotation time of the fuser, and also the length of time the fuser is at a high temp, I have rebuilt some of these fusers, with grey market belts and pads, the problem with them is the oil pad is poorly designed, and begins to stretch and gather, causing the fuser belt to get tight, causing fuser jams at about 40 K, if somebody could come up with a better quality oil pad, it would solve the problem. Has any one seen one ???

Maybe it's just me, but Kyocera has always struggled with their fusers, very little ever make a full life.
