Hi guys! I have a copier bizhub 227 which gives me problems. On the FIRST PAGE (copy or print) after it comes out of standby, it leaves a mark on the background of the page like a shadow as it appears in the attached image.The following pages are clean and the print quality is good. This situation occurs only when the device comes out of standby mode or sleep mode when the display is off. I mention that the drum and developer unit is new and transfer assy also. What could it be?

Re: Bizhub 227 first page with "shadows"
Fusing temperature/fuser? Check temperature and increase it accordingly Service Manual if still no improvements try another fuser unit. Did you happen to rebuild the fuser prior or anything like drum unit or developer unit or transfer roller?A tree is known by its fruit, a man by his deeds.

if it was from the fuser and it wasn't the right temperature, couldn't that mark be taken off the sheet with your finger? she is fixed. without reconstruction at the units. changed new oemComment

I'm a tech more than a junior. Total counter 127435
the thought leads me to something on the source board/power board like a capacitor that does not work properly when changing the working modes from sleep to wake. I will keep checkingComment

Hi!
You mentioned to have replaced the Transfer assy, does this one include the transferroller?
The roller might be stuffed with toner or paper dust.
Worth trying as well is to put the fusing temperature higher. (Service menu -> Machine -> Fusing temp)Comment

Re: Bizhub 227 first page with "shadows"
If the following prints come out clean, it's a sign that the fuser unit doesn't heat up enough when it comes back from sleep. As it prints, the unit warms up and cleans itself, doing its job properly. I would disable this service or configure it correctly for your needs.Comment
