Laser Printer needs servicing (Addiscombe CR0)

Kyocera Ecosys P5021CDW laser printer. Big and heavy. NEEDS SERVICING: the rollers always produce ugly streaks on about the first three to five sheets printed, and colour balance not perfect. However, it is functional and has toner and spare toner cartridges (one of each). Note that changing the cartridges WILL NOT solve the streaky problem, as the streaking is caused by the rollers (which are internal components), not the toner boxes. Item comes in original box, and otherwise clean and in very good condition. Let me know when you can collect, and please provide a name and contact number. Thank you.
