e-Studio 720, runs REALLY slow...

[Oystercopy]

I swear, sometimes I get the REAL winners...

This machine was installed about 3 months ago, fully PM'ed and serviced. Has only about 200K on it. All firmware is ver. 345.

The other day, it starts jamming on the customer. The initial jam code is EAE0, so we pull the Finisher and the machine seems to run fine, except REALLY, REALLY SLOW... Runs about 25 copies per minute instead of 72 (??!!).

(quick note: when it had the Finisher on it, it would take way too long keeping paper in the finisher's buckle chute before trying to exit it out so we feel that the machine's extremely slow speed was causing the jam in the first place. Hope this makes sense). We were advised to replace the RAM and then the System Board. Tried both, neither worked.

Have you guys any other ideas 'cause I'm scratchin' my (gettin' balder) head... Could the Logic board cause this? Power Supply maybe?

Thanks in advance,
OC

Is time between pages slow, or does it seem MFP is running slow? Could be fuser temp detection is mis-reading, or adding toner (you mention PM). Are prints same spped as copies? Emujo

logic board controls all of your motors and sensors clutches etc... I would suspect it. The interface for the finisher also plugs into the logic board so that kind of makes sense with what you are saying. Note, the logic boards are not swappable modle to model you have to get the one for that particular model.
