LBP3100 / LBP3010B
Description
There is sometimes a case where the difference of temperature between air and inside of the machine causes moisture to occur on the toner immediately after the
power is turned on for the first time for the day.
As a result, when the toner transferred on a sheet at the time of initial printing passes through the fixing assembly, moisture on the toner is vaporized into steam,
causing breading (smear) to occur.
Field Remedy
Prevent bleeding using the following user mode items.
