I have an print quality issues where there are full sheet width bands at 10" on center perpendicular to the sheet feed direction, parallel to the axis of the drum on the first prints in the morning or for prints coming out after it has been idle. Which component would be causing this? Also does anyone know if the replaceable parts (drum, etc) of this printer are the same as the new Plotwave series? If not, should I be concerned about finding parts since this printer has been discontinued? Thanks.
