imageCLASS LBP633Cdw beeps (twice) when printing starts

[Rhaaziel]

Hi, as mentioned in the title, each time I send any file to the printer it beeps twice before the printing starts.

There is actually one long beep just before printing, and the second one also laud and long when the printing is in progress.

Any ideas how to solve this?

I am using original toners which are about half full, there are no errors or visible problems.

Many thanks!

I just found a very similar post and it was exactly the same issue… UPS was the issue, and guess what there I the same problem at my side, when I use UPS (which is located directly behind the printer) it beeps, but without the UPS no beep 😊😊
