KM-3040 pausing during duplex copies

[Sudsybrew]

I have a KM-3040 that prints the first 7-8 duplex prints just fine, but after that, pauses during each copy. It just stops and acts like it is "thinking". No error messages. Sometimes it resumes after just a few seconds, other times it takes a minute or two. There is no optional hard drive, print system, fax. Just a key counter - could the key counter be the problem, or do we have a RAM issue, or just something I'm not thinking of?

BTW - copying just one page, duplex.

Thanks.

Have you updated firmware? What emulation are you using on the printer and print driver?

[Sudsybrew]

Firmware up to date and these are copies, not prints. There is no print system on this machine.

Raise the Fixing Temps back to Factory Settings, someone lowered them. I only know because I've had this same problem after lowering the fuser temps on this engine.

You are probably dead on - I lowered the fixing temperature the last time I was there. Thanks for getting me on the right track!
