Open heat cycle error SCX-6322

[Nathanthea]

We replaced the fuser unit and it will only works for 2-4 days. After that the open heat cycle error appears again. We've replaced the fuser unit 4 times.

Is there anybody who encountered this problem?

Do you think there is a problem on the SMPS or It needs to upgrade the firmware?


Help.... Thanks.

Update the firmware. It's "supposed" to fix this issue! (not my fav machine!).. Then replace the fuser/thermal fuse.

Actually my choice was the SMPS. That has fixed that issue on many of the tabletop Samsungs. Is it just a blown thermostat or a genuine meltdown with the rollers inseparably welded together? I've seen both. =^..^=

[Nathanthea]

Yeah both, blown thermostat and meltdown rollers. Is there a new part of SMPS release by Samsung? Thanks to all.

The parts book is a little confusing on this. For 110vac machines there are two different part #s listed (JC44-00091A & JC44-00126A). When you search the two numbers the first is a SMPS for a CLP-610. The latter number is the correct number (JC44-00126A), and no updates. =^..^=

Yup its a quality box, they came out with firmware and a newer style complete fuser unit (with a "better" exit sensor actuator). Not seen a power supply issue with these yet tho but I (thankfully) only have about a handful in the field!

Hi, I'm having the same problem - SCX-6322 printer stating Open heat cycle error. Can someone please tell me what part/s I need and how to go about replacing. Thanks in advance

The answer is in the previous posts. If you cannot glean the answer from the posts above you should contact a technician. =^..^=

certain serial numbers there calling to replace the main board for the open heat error....along with replacing with a new style fuser

[just a tech]

They found a problem with the fuser control circuit on the Main PWB. The only machines supposed affected were ones manufactured from march 2008 till december 2008. if your machine was manufactured during that time, you should replace the Fuser Unit & the Main PWB at the same time. They have supposedly modified all of their boards in stock so any main from samsung should be good now. Hope this helps.. Good luck
