I've seen something like this-any error codes? Old drums? Sometimes a failing drum unit can cause these kind of issues.

All the drums are about 2 months old and there no error codes. I did clean the fuser unit before it started to happen.
Thanks for help

can indicate a problem with FU27 on the fuse pcb. The indication to replace all four toner cartridges can be a result of low voltage output from this fuse (ie: 5vdc on one side and 2vdc on the other indicates a bad fuse). To check the fuse use frame ground for your volt meter negative lead and measure both sides of the fuse for 5vdc, if it measures anything other than 5vdc replace the fuse pcb. You can also check the output of this fuse at connector J64 pin 5, this 5vdc is supplied to the dc controller. NOTE: During normal servicing of the machine it is important to turn the main power switch off prior to unplugging connectors, failure to do so can result in damaging circuits and degrading or blowing fuses on the fuse pcb.
