PPS Product Performance Specification
PQ Print Quality - PQ is the post-pixel placement, i.e. transfix / mechanical
which differs from IQ which is pre pixel placement.

PWB A Printed Wiring Board Assembly
PWS Portable Work Station
RaLPH Registration and Long Pre Heater (to warm and register the media prior
to meeting the image on the Drum) - detects and corrects skew to within
2.5 Millie-radians. Has three sets of rollers - each set is selected and
used only for certain widths of paper / throughput (i.e. when running small
throughput you would only use the inner pair). The RaLPH is referred to
as the Registration / Preheat assembly in the service documentation.
RAM Random Access Memory
RARP Reverse Address Resolution. Reverse of ARP. Converts a MAC address
to an IP address. The document centre resolves its address using RARP.
See also MAC, NIC and ARP.
RBT Ring Back Tone
RCA Remote Customer Assistance
RDT Remote Data Transfer
R/E Reduction / Enlargement
REN Ringer Equivalence Number
Reset head sensi-
tivity data Undo the effects of “Measure head sensitivity” and “Head to head unifor-
mity”
Resolution Scanning resolution - generally in PPI or pixels per inch
Reverse Text Text that is created by printing an ink field around the text letters, leaving
the text visible as the media colour (generally white media).
RGA Tool for projecting reliability

Term Description
RGB Red/Green/Blue - colours additive primaries - used by emissive devices.
RPC Remote Procedure Call
RH Relative humidity
RIP Raster Image Processing - Software creates four separate maps or pat-
terns of dots called Raster images for each page of output - one for each
CMYK - called colour separations
RIS Raster Input Scanner
RJ 45 Phone type network connector
RM Requirements Management
RML Recommended Media List
RMS Root Mean Square (AC effective voltage)
RNR Receive Not Ready
RO Regional Operations
Roll Alignment of the print heads (levelling direction)
Roll Off Refers to transfix roller rolling off the trailing edge (presently maintains
transfix position if in burst mode but releases in say single print mode)
Roll On Refers to transfix roller rolling over the leading edge (presently at 90% of
normal pressure) changes somewhat in burst mode.
Roller Ghosting Inherent to product - generally on duplex - contributors are oiling and
transfix roller
ROM Read Only Memory
ROS Raster Output Scanner
Roving Jet Refers to random missing jets - which the root cause is largely unknown.
RR Receive Ready
RS-232, RS-423,
RS-422, RS-485 Series of standards for serial communication of data by wire. RS-232
operates at 20 kbits/s, RS-423 operates at 100 kbits/s, RS-422 and RS-
485 operate at 10 Mbits / s. See FireWire and USB.

RTN Retrain Negative
RTP Retrain Positive
RTS Request To Send
Rx Receive
Runout Concentricity inconsistency in the drum - which may result in PQ defects
unless the IOD fully and correctly compensates for the runout. Runout as
a defect may look like a bump in a line or a non circular circle.
