Fine lines on mono laser's prints

  Diemmess 09:04 05 Nov 2015

Samsung mono laser M2835DW less than one year old.(40% toner used) Very many fine lines on any predominantly black part of every print. Lines follow the paper i.e. from top to bottom of a portrait page.

Have tried careful wiping of the green (Photo-conductive roller) with paper from a kitchen roll. Didn't see any speckles or dirty tissue. It must be a dirty green roller but has anyone an alternative suggestion?

It is never a good idea to try cleaning the roller. It is almost certain that it has been damaged in some way and cleaning it with kitchen roll can potentially cause even more damage. Have you been using poor quality paper with rough edges. Laser paper is specially cut so the edges are not sharp and don't damage the roller.

Unfortunately for you, Allan's answer is probably the correct one. The cost of fitting a new drum may exceed the cost of a replacement Printer.

You are probably correct on all counts! I have gambled through Amazon that I will cure the trouble by a fitting a replacement (original) drum kit. Before anyone thinks this is something exotic for Audio or games, the advert does mention photoconductive. Thank you again, are drum plus toner supply the only parts with a measurable life span?

Many printers will be useable for years and are replaced, primarily because consumables become expensive as the number of units in use throughout the world, drops to a point that it is no longer economic to make replacements.

Sometimes the Fuser Unit and/or the Waste Toner Unit need replacing but that would be unusual.

It turned out to be the toner unit. This model has a roller and some sort of brush device as part of it. Smooth print again at a third of the cost of a new printer. Thanks everyone for your interest.

Usually known as a Drum. It was probably scratched

That can happen if you use cheap non laser paper. Laser paper is specially cut on the edges to be round rather than sharp so they do not damage the drum unit. False economy.
