Functional problem, error 991 sometimes 990 appeared on the screen. What exactly this error means? Is there a way to reset this type of error?

How many copies has your drum and dev done?

When they start to wear you'll get this code along with half a ton of dev in the PCU

As he said check drum and dev. unit...fatal kernel error culd mislead you as it makes you think it's software or controler problem.
My guess is that machine can't check itself propperly,comunication with other boards and assembly's,reading the state of some assembly...some voltage reading is abnormal is in ilogical...something that machine isn't prepared for.
It all comes down to drum,sometimes it's not seated propper on small machines,sometimes one has to change drum.

The copy counter of the machine is near 700k and so as developer and drum.It didn't undergo drum replacement yet.
