Horizontal lines on Samsung 2835

Istalled printer 2 years ago and worked fine then.  Did not use since then as waiting for old printer to run out of toner.  Started to use "new"printer but find horizontal lines either side of page every 75mm.

Have cleaned drum and reinserted toner which has made no differance.  Are the lines comming from drum ,toner, or fuser unit ??

2 year not being used is quite a long period, you are having drum problem (75,49 mm is drum circumference).

Try printing more pages maybe it will fix by itself.

Thank you for confirming my suspitions. I will do as you suggest and continue to use printer as is.   If no improvment will have to get a new drum unit.
