Abstract
An electrostatographic printer has a transfer zone at which a toner image is transferred from a moving photoreceptor to a copy sheet, and a cleaner blade for removing residual toner from the photoreceptor after image transfer. A trap is provided to collect paper fibres and other debris from the photoreceptor after the transfer zone and before reaching the blade. This debris would otherwise impair the ability of the blade to remove toner. The trap comprises a strip of compliant material such as a velour fabric which is suspended by its ends above the photoreceptor so as to hand under its own weight and to brush lightly against the photorecptor. The fibre trap may be included in a removable xerographic unit incorporating the photoreceptor and other process means and adapted to be removable mounted in the main assembly of the copier.
