Used cheap Amazon TN250 "compatible catridges in my MFC250. Both did not fit well. Now the printer prints blank stripes on the page as well as some straight stripes. Tried real Brother TN250 toner, but not fixed. Replaced the DR250 drum as well with Brother part. Still an issue.

Ussally drum/toner would fix, will not be fuser, I would suspect Hi voltage board or laser unit, In australia these machines carry a 2 year return to base warranty.
Try reseting the drum counter, this also resets Bias voltage, might be your problem. open front cover with power on and press set, arrow to change drom and select yes.
Otherwise it would be a high voltage board problem, possibility alsoexist that it could be laser unit
Check status page for "71" errors, menu * 2 8 6 4 very very fast, machine will beep "maintence displays" then 77 to print out status page, 99 to return to normal.

Normally clearing the drum count the machine has to be on open front cover as if to change the drum press and hold the button in for about 10 second then release and shut the door. This should reset the count if not please get back to me and I'll check the service manual to see if anything in that.
Thanks J

To get every bit of toner powder out of the cartridge, first remove the toner unit from the drum assembly. Second, find the little circular window on the right-side of the toner cartridge. Third, place a piece of black electrical tape over the clear window, cannot be clear tape. Fourth, re-install the toner cartridge into the drum assembly. Last, put the complete unit back into your printer. This worked for me.

You have to open the door and hold the go button til all lights flash. That tells the printer it has a new drum. After that press the go button 3 times and it will print a report that shows the drum as new...
